Things To Consider Before Looking

Find about two or three pipe comparison charts that specifically note material, applications and corrosion resistance. This can help narrow down a lot of close choices when price becomes the deciding factor. The charts will usually say the same thing about the steel pipes you are considering. When conflicting information is found, you can always add an additional chart to get a clearer picture of the details. Don&#;t underestimate the power of doing side by side comparisons when looking at steel pipes. That one feature you overlook could be the biggest thing you need when starting a new project.

A Rundown Of The Different Steel Types

There are three main steel types that are worth mentioning. Carbon, alloy and stainless steel are the three types that you will do the most business with. Carbon is strong and easy to work with. With its low number of alloying elements, carbon is also one of the least expensive pipes to get. Alloy is strong against impact while also being more resistant to stress. The many combinations of alloy means that high quality mixtures are more profound in the industry. Stainless steel does not rust, and therefore is a huge benefit for steel pipes. In industries where corrosion protection is mandatory, stainless steel reigns supreme.

 

What Is The Grade of The Steel?

One of the first steps to getting steel pipes is to determine what grade is needed. Narrowing down steel pipes will always require knowing what grade will do the best job. But regardless off the grade, the sizing will remain the same since it follows the same industry standard. Consider that one less variable you have to worry about when getting a steel pipe. ASME and ASTM usually have piping specs that show which grades of steel are beneficial for your project. The main difference between the two is that they have different standards to go by. Even though the grades are similar across both spec sheets, their standards will often determine what testing is done for each.

 

The SAE and AISI are two other organizations that should be looked at for steel pipe grades. Their numbering system simplifies a lot of the more complex classifications of steel piping. Keep in mind that the numbering system is only one part of the specifications needed when ordering steel pipes. This is a good example of where the information from the other organizations come in. SAE/AISI combined with ASME/ASTM gives you a full profile when deciding which steel pipe is better for your project.

The last grade sort of sits by itself, and for good reason. API 5L is strictly used for the oil and gas industry. As its own category, the grade has multiple delivery conditions to choose from. Things can get complex when comparing the different options with API 5L. Just like the previous choices, the grades are there to help you narrow down what works best for your industry.

Choosing Between Seamless or Welded

Tons of customization options for steel pipes include the choice of seamless or welded. This requirement changes on each project, so you must know which one will get the job done. Welded pipes are more cost effective than seamless, especially when buying in bulk. The consistency from pipe to pipe enhances the wall thickness. To keep this consistency active, manufacturers can check the internal surface of the tubes. This is something you can&#;t do with seamless pipes due to the way they&#;re made. Seamless pipes have the advantage with consistent roundness and lack of seams. Often, a weak seam in a pipe can be a future headache for a project. By eliminating that issue with seamless pipes, you have one less problem to worry about. This feature becomes important when you&#;re worried about corrosion or breakage.

Getting Bundles

Buying in bulk will always have its advantages. When buying pipe bundles, you get the added benefit of mixing length and size. The discount you get by buying cut-lengths of pipe can save your company a ton of money. The savings don&#;t end there, and also apply to businesses that purchase pipes at full length. Depending on where you get it from, buying at full length may carry a larger discount than buying mixed. Pay attention to a manufacturer&#;s pipe page to see where the most savings are. Chances are full length steel pipes will see the biggest savings when purchasing or larger projects.

Quantity

Buyers that aren&#;t concerned about price still need to know the footage of pipe needed for a project. It is one of the requirements for a quote and should be one of the top things on your purchase checklist. With this information, you may be able to plan for future projects that require the same materials. When price is a concern, going over what you need will cost you more on both ends- purchase and cleanup. Trying to buy extra in case a mistake happens will lead you to a bottomless hole. Planning carefully is the only way to prevent this from becoming a problem with steel pipes.

Pipe Size

Sizing specifications often contain plumbing terminology that buyers are not familiar with. Know your fittings and what steel pipe sizes will be compatible before committing to an order. Pipe fittings and sizes can always be research using a manufacturer&#;s chart, if one is provided. When you&#;re left to figure it out on your own, it is a good idea to create a personal reference table for the company. Update and refer to this table whenever you need to make a purchase for new steel pipes.

Verify Suppliers

Someone telling you that a specific supplier is the best in the world is only one part of the selling point. Do your own footwork to find out if a steel pipe supplier is compatible with your company. There are different top choices based on region, project type, grade and more. That means suppliers in Asia will have different benefits than suppliers in America. On top of the locational differences you must consider bulk price history. There are suppliers that may never offer a discount, even when the market is not in their favor. When price is your driving factor for a project, this is something that you can&#;t ignore.

Why Coating Matters

Coating gives steel piping additional properties to make it more attractive to the buyer. Black steel is cheaper to manufacture but great as an alternative to galvanized pipe. Projects that require the transport of gas will fair better on price by using black steel pipe. Although its weakness is water, you can save a ton if the project aligns with the strength of black steel.

Galvanized steel is stronger than black steel, and therefore more expensive. It is strong against corrosion and can carry water without a problem. Mineral deposits have a hard time building up in a project that uses galvanized steel pipes. Despite its strengths, this type of pipe is weak when transporting gas. More than one company has purchased black steel when galvanized steel pipes would have been a much better fit.

Pre-painted steel has multiple uses, from residential to business. Coil coating is used to apply different types of coating materials. All of this leads to a steel pipe that delivers both in design and durability. As the most flexible steel pipe coating, it can be used on multiple projects and is still competitively priced. Pre-painted steel can be as durable or as visually attractive as needed for any project.

A Small List Of Red Flags

You won&#;t run into a lot of scams in the steel pipe industry when going with a reputable supplier. Manufacturers of steel pipes have a reputation to keep. That makes it very difficult for larger companies to scam the little guy. That doesn&#;t mean you should ignore obvious red flags that pop up. This information applies when dealing with smaller companies. When you find yourself in a situation where a smaller company is the best deal, check for reviews. A company with no reviews is a bad idea to pour money into. Another red flag is when a smaller company doesn&#;t offer enough information about the product. This applies to companies of all sizes, but for smaller steel piping companies it is unacceptable. The buyer is expected to do some of the research, not all of it.

Wrap Up

The number of charts made for steel pipe recommendations is staggering. Don&#;t let the information overwhelm you into making a rushed decision. Whether for personal or professional use, getting the right steel pipes comes down to research. Take your time, and the final decision will make all the difference in the world.

Buying steel pipes seems to be an easy task, but how to buy them correctly and effectively can be a difficult one. In the blog below, Chinh Dai Steel will show you things you should consider before buying steel pipes.

I. Overall about steel pipes

1. What are steel pipes?

Known as the most utilized product made from steel, steel pipes are cylindrical tubes with thin walls and hollow structures that are used in many ways in manufacturing and infrastructure. Depending on the purposes, steel pipes can be galvanized or used for further manufacturing processes. 

2. Application of steel pipes

Steel pipes can be found anywhere in the world. The primary use of steel pipes is in liquid & gas (underground) transportation including oil, gas, and water. However, the main purpose of steel pipes is throughout the manufacturing and construction industry. With the strength, durability, and ability to withstand extreme temperatures, pressures, and destructive elements, steel pipes make it possible to be the initial part of every building & construction. 

3. Classifications of steel pipes

There are many ways to classify steel pipes but the most common method is based on their characteristics. We then have 04 popular classifications of steel pipes: carbon steel pipes, stainless steel pipes, black steel pipes, and galvanized steel pipes. 

a. Carbon steel pipes

Being made of steel in which carbon is the main chemical element and determines the extent of the metal&#;s physical characteristics such as strength and toughness, carbon steel pipes are considered the most cost-effective type of steel pipes. During the manufacturing process, producers add carbon to iron so as to harden and strengthen the resulting metal.

Based on the purposes, carbon steel pipes are also classified as ultra-high carbon steel pipes, high carbon steel pipes, medium carbon steel pipes, low carbon steel pipes, and mild carbon steel pipes. 

Carbon steel pipes are mainly used in transporting water and wastewater underground, in industrial operations involving high temperature&#; 

b. Stainless steel pipes

Stainless steel pipes are widely known for their considerable corrosion resistance and in great demand in many countries. Also known as inox steel pipe, they are made of steel containing iron, carbon, and at least 10.5% chromium content, in which chromium is the main element. In stainless steel pipes, there is a passive layer that helps to protect the metal from deterioration which is made from the reaction between chromium and oxygen. 

Stainless steel pipes are commonly used in construction, transporting fluids, and other industries such as automotive industries, pharmaceutics&#; 

c. Black steel pipes

Black steel pipes are the most highly stable structured steel pipe for sale thanks to their convenience and high stability. Also called raw or bare steel pipes, black steel pipes are made of steel that is not covered with any kind of coatings. The &#;black&#; in its name derives from the dark-colored iron oxide cover formed on its surface during the fabrication process.

Black steel pipes are also used in transporting water & oil and the construction industry, especially in making fences and scaffoldings. 

d. Galvanized steel pipes

Galvanized steel pipes are made of steel that is coated with several protective layers of molten zinc to prevent the pipes from rust and corrosion. The galvanization process was invented in the s and galvanized steel pipes have replaced lead-based pipes since then. 

Mostly used as water conveyance and building materials, galvanized steel pipes are broadly applied in many industries such as automatic and general engineering industries, bus body, and railway bogies manufacturer&#; 

II. What you should consider before buying steel pipes? 

Since steel pipes have many classifications and a wide variety of applications, we need to consider carefully before giving out the buying decision. 

Below is a list of things that you should consider before choosing any steel pipes for your projects and constructions. 

1. Which type of steel pipes are you looking for?

Before buying anything, you need to determine the exact classification of steel pipes you are in need of and what you are going to do with the pipes. As listed above, there are 04 types of steel pipes with different coating and characteristics. Carbon steel pipes are the least expensive pipes to get while stainless steel pipes do not rust. Galvanized steel pipes are coated with several layers of zinc which enhances the corrosion resistance and strength while black steel pipes can be used in many industries such as construction, fire fighting, fence making, scaffoldings&#; 

2. The grade of the steel pipes

Another step to get the correct steel pipes is to determine the grade of steel you need. You can base on international standards to pick out the most suitable steel pipes for the projects. The ASTM and ASME standards usually have piping specs that help you a lot in showing you which grades will do the best job. However, there are still differences between these two standards, which resulted from different testing methods applied. That&#;s why you should check the specs carefully when choosing the right grade of steel pipes.

Besides, you can also count on SAE & AISI &#; the two other organizations that are well known for steel pipe grades. Their numbering system simplifies a lot of the more complex classifications of steel pipes, however, not the whole specifications when choosing the correct pipes. 

When basing on international standards to find the correct steel pipes grade, you should refer to industry standards as well. For example, if you are looking for oil and gas transporting steel pipes, the API 5L standard will do the job. It is the industry standard for oil and gas transporting pipes. When there are a lot of standards to consider to make the buying decision, you should combine them together to have a full profile to narrow down what works best for your projects. 

3. Seamless or welded steel pipes?

The customization options of steel pipes are also an important factor to consider when buying steel pipes. Of which, there are the 02 most popular options of customization: seamless or welded. The decision is mostly based on your choice of what would best suit your needs. However, most welded pipes are more cost-effective than seamless, and it becomes a huge thing to consider when you buy in bulk. 

Also, the consistency from pipe to pipe, which enhances the wall thickness, also an important factor to count when choosing the customization option of steel pipes. Manufacturers will keep the consistency by checking the internal surface of steel pipes, which could be extremely difficult when it comes to seamless steel pipes due to the way they are made. Hence, if you are finding steel pipes with a high consistency from pipe to pipe, welded steel pipes are the best choice.

However, seamless pipes are without seams (of course) and have the advantage of consistent roundness. Hence, there will be no chance for a weak seam, which might lead to a headache problem for the projects in the near future. 

4. Quantity

Whatever you buy, buying in bulk always gets you a better price. Besides, you might have the added benefit of mixing steel pipes length and size or getting customize-to-need pipes; which you will never have once you buy in small quantities. 

Besides, if you purchase pipes at full length, there might be extra benefits from manufacturers. To get this, you should pay attention to reputed manufacturers&#; websites to know where the most savings are. 

In case you are not concerned about the price, you still need to consider the quantity of steel pipes you need to get the correct quotation. Some steel manufacturers only sell steel pipes in exact quantities. Also, to avoid mistakes happening during the projects, you might want to buy extra steel pipes to take the initiative. 

5. Pipe size

Specifying the steel pipes&#; size might be a problem since it often contains plumbing terminology which is not familiar to most buyers. It&#;s essential to know the fittings and size before ordering any steel pipes. You can research the fittings and sizes based on manufactures&#; charts, or consult with the sellers. If you buy in bulk, it&#;s easy to get steel pipes customized to your needs and wants. 

6. Why does coating matter? 

Steel is strong already, but the coatings give out additional properties as it protects the steel itself from corrosion and harsh weather conditions. Hence, steel pipes with coatings are highly recommended when you are finding ones that are strong and durable. Others&#; based on your needs and budget. Black steel pipes are the alternative option for galvanized steel pipes if you just need steel pipes to work on other projects such as fences, barricades&#; Meanwhile, galvanized steel pipes are strong and protect perfectly against corrosion and do the job better in transporting water. 

Pre-painted steel pipes are also a good choice from residential to commercial with their multiple uses and competitive prices. It is durable yet also visually attractive, which is needed for any project. 

7. Choosing reputed suppliers

Choosing the correct type, quantity and coating is not sufficient if you cannot find a reputable supplier that manufactures high-quality steel pipes. If you need to find trusted suppliers by searching and scrolling through the feedback section, here are some factors you should refer to:

• They have mills with high production capacity
• Their products should be qualified for specific international standards which are widely applied for their purposes
• It should be easy to track the origin of the product on its labels and QR codes, which ensures you are buying the steel pipes from a prestigious supplier/manufacturer
