Large-Capacity Horizontal LPG Storage & Pressure Vessel

Product Structure

• Massive Pressure Shell: A heavy-gauge, high-tensile steel body cold-rolled and welded for extreme pressure containment.

• Hemispherical End Caps: Optimized head design to distribute stress evenly across the vessel’s structure.

• Reinforced Heavy-Duty Saddles: Oversized steel support structures that stabilize the vessel and allow for secure mounting on concrete foundations.

• Manway Access Ports: Multiple large-diameter flanged manholes for safe entry, internal maintenance, and non-destructive testing.

• Instrument Flange Array: A series of top-mounted ports for liquid level transmitters, pressure relief valves, and temperature sensors.

• Industrial Safety Coating: Multi-layer, high-visibility yellow polyurethane coating for maximum UV resistance and anti-corrosion protection.

Product Advantages

• Exceptional Volume Efficiency: Designed to provide massive storage capacity within a streamlined horizontal profile, optimizing land use.

• Rigorous Safety Testing: Undergoes 100% radiographic (X-ray) weld inspection and high-pressure hydraulic testing to ensure zero-leak integrity.

• Advanced Material Durability: Utilizes specialized pressure vessel-grade steel (Q345R or equivalent) to withstand thermal cycling and internal stress.

• Turnkey Logistics Support: Engineered with reinforced lifting lugs and saddle geometry compatible with global heavy-transport equipment.

• Weather-Resistant Finish: The industrial-grade yellow topcoat provides an effective thermal barrier and protects against harsh outdoor elements.
