How to Maintain LPG Spherical Tanks

As we all know, LPG (Liquefied Petroleum Gas) is an easily combustible gas that is used in many industries for various purposes such as heating, cooking, and powering vehicles. Its storage is a crucial aspect that requires utmost care and maintenance. Spherical tanks are among the most common methods of LPG storage.

Maintaining LPG spherical tanks is an essential responsibility of the operators to ensure safety and reliability. As an expert in the industry, I have penned down some valuable guidelines on how to maintain LPG spherical tanks.

1. Regular Inspection.

The first and foremost responsibility is to keep an eye on the condition of the spherical tanks regularly. As per the industry standard, an external inspection needs to be carried out once every six months, followed by an internal inspection every ten years. The inspection is conducted to check for any damage, corrosion, or leakage that may have occurred.

External inspection is done by visually inspecting the tank's outer surface for any cracks, deformities, or other sign of wear and tear. In contrast, an internal inspection requires a certified professional to inspect for any signs of rust, corrosion, or residue accumulation inside the tank.

2. Maintenance of Coatings.

The surface of the spherical tanks is coated with special paints or coatings that prevent the tank from corroding and rusting. Regular maintenance of these coatings is necessary to keep them in good condition. Re-coating might be required when the surface coating starts showing signs of damage or wear and tear.

3. Valve Maintenance.

The valves control the flow of the LPG from the tank to the end-user. These valves need to be serviced regularly. The seals and other internal components must be replaced periodically to avoid valve failure and ensure a smooth operation. A hard-to-turn valve or a leaking valve is signs that maintenance is due.

4. Emergency Vent and Relief Systems.

LPG tanks are designed with an emergency venting and relief system that releases excess pressure to ensure the integrity of the tank and the safety of the users. These systems must be regularly checked to ensure proper functioning. In case of any blockage or damage, the repair or replacement of the relief valve is necessary.

5. Safety Measures.

LPG tanks must be maintained with all safety precautions, including fire protection, lightning protection, and anti-static grounding systems. Their proper maintenance and inspection guarantee the reliability and safety of the complex system.

6. Cleaning.

Spherical tanks need regular cleaning to prevent the accumulation of debris inside the tank. The debris foreign to the environment can clog the valves and can cause severe damage if not addressed timely. Regular cleaning removes the accumulated residue and debris and keeps the internal surface clean and free of impurities.

Final Words.

In conclusion, LPG spherical tanks play a critical role in the LPG industry, and their proper maintenance is essential for sustainable operations in this industry. The key to maintaining LPG spherical tanks lies in timely inspection and regular upkeep, and addressing any issues as soon as they arise. The safety and reliability of the users depend on the proper maintenance of these tanks. Therefore, I highly recommend that proper precautionary measures be taken and that the guidelines mentioned above be implemented to maintain LPG spherical tanks.
