Liquefied Gas Swivel Pipe

Liquefied gas crane pipes are composed of flexible rotating joints with excellent sealing, connected in series with pipelines. They are used for the transmission of liquid mediums between tank trucks and bridge storage pipelines.

Our company's fluid handling arms come in a wide range of specifications and types, are safe and reliable to use, operate easily and flexibly, are convenient for installation and maintenance, and have excellent sealing performance, giving us a significant edge in the domestic industry.

Key component of the liquid gas crane arm: rotating joint; most leaks are due to the leakage of the rotating joint.

The manufactured swivel joints feature an advanced double raceway structure internationally recognized, made from high-strength alloys or stainless steel, and equipped with PTFE (enhanced polytetrafluoroethylene) seals for extended service life. Utilizing a state-of-the-art production process, they ensure long-term usage without any leakage.

Key Features of Liquefied Gas Swivel Fittings:

◇ Features a compound double-track structure

◇ Made of alloy material or stainless steel

◇ Use polytetrafluoroethylene seals

The track surface can undergo nitriding heat treatment.

◇ Suitable for various media properties

Pipe Welding Technology

All process pipelines are TIG tungsten argon arc welded.

◆ Features of Liquefied Gas鹤管 products:

1) Dual-channel swivel joints and sealing rings with elastic cards ensure no leakage during loading and unloading of media.

2) The balance cylinder balancer with a遇balance design makes the loading and unloading arm operation easy and labor-saving.

3) During loading and unloading, follow the tank truck within its normal movement range.

4) When the crane arm is in storage position, it locks parallel to the direction of the tank truck, occupying minimal space.
