The LNG loading and unloading arm is evolved from stainless steel corrugated hose. The loading and unloading arm is flexible in rotation and good sealing performance.

It is composed of high-quality, large load-resistant rotary joint, pipes, pipe accessories, balancing devices, support mechanisms, etc.

The column load-bearing structure is adopted to reduce the mechanical stress of the process pipeline to the lower limit, thereby maximizing the product.It has a long service life and is used for fluid material transfer between tank trucks and storage and transportation pipelines.

LNG loading and unloading arms are widely used in places where unloading superchargers are used to unload trucks, such as: gas filling stations, storage stations,itused in various gas stations such as receiving stations, transfer stations, LNG liquefaction plants, etc. It greatly reduces the company's production costs and ensures the safety of operators.

The LNG loading and unloading arm consists of three pipelines: liquid pipeline, gas pipeline, and pressurized liquid pipeline integrated into one column.

It consists of a rotary joint, pull-off valve, cryogenic valve, inner arm, outer arm, spring steel, static conduction device, nitrogen blower

It is composed of a cleaning device, a column and other components. This rotary joint does not require nitrogen purging and can be used normally.

Useful, light and flexible.
