LPG Skid Tank with Safety Control System

Product Overview

This LPG skid tank with safety control system is a fully integrated pressure vessel unit designed for the safe storage, separation, and dispensing of liquefied petroleum gas (LPG). Available in both ASME and Chinese GB standard configurations, this skid-mounted system combines a horizontal storage tank with a complete safety control system including safety valves, pressure meters, and cut-off valves on a single structural base.

The system is engineered to handle flammable and toxic media with a pressure range of 0.1MPa to 1.6MPa. Available tank capacities range from 6m³ to 200m³, with customizable materials including SA-516, SA-517, SA-612, P460, Q420R, and Q370R. The skid tank features a built-in full-lift spring safety valve, 5-second closure time, and 550 kg/m³ filling capacity, with a maximum payload of 30 tons.
