Product Overview

This 150m³ LPG storage tank is a large‑capacity pressure vessel specifically designed for the safe and reliable storage of liquefied petroleum gas. Classified as a Category III pressure vessel, this tank is manufactured to the highest standards of quality and safety, with a design service life of 20 years.

The tank is constructed from high‑quality steel with an 18mm wall thickness and features a robust design pressure of 1.71 MPa. Every weld seam undergoes 100% non‑destructive testing (RT) to ensure structural integrity, and the entire vessel is subjected to overall stress‑relief heat treatment for enhanced durability and fatigue resistance. Manufactured and inspected in strict compliance with GB150‑2011 and the “Fixed Pressure Vessel Safety Technical Supervision Regulations,” this LPG storage tank represents a reliable solution for industrial gas storage applications.
