Liquefied gas crane pipes are divided into bottom loading and unloading trucks and top loading and unloading truck crane pipes. They are connected to pipelines by flexible and well sealed rotary joints, and are used as equipment for liquid medium transmission between tank trucks and storage and transportation pipelines on pallets. The key component rotary joint is processed using precision CNC machine tools, with a built-in double raceway support structure, which can rotate flexibly and is lightweight and reliable. The outer ring is made of alloy steel, while the inner ring is made of stainless steel or lined with polytetrafluoroethylene to ensure its safe and reliable use in high temperature, low temperature, and highly corrosive media. The sealing ring is made of reinforced polytetrafluoroethylene material, lined with stainless steel elastic support ring, and the seal is polished, which has superior self-lubricating performance and super strong corrosion resistance.

Usage: Loading and unloading operations at the bottom of tank trucks

Applicable media: liquefied gas, liquid chlorine, liquid ammonia, etc

Working pressure: 1.0Mpa, 1.6Mpa, 2.5Mpa

Pipeline material: carbon steel/stainless steel/aluminum

Nominal diameter: DN50-DN150

Product features:

1. The rotating joint of the double raceway and the sealing ring with elastic card ensure that the loading and unloading medium does not leak;

2. The balanced spring cylinder balancer makes the loading and unloading arm operation light and labor-saving;

During the loading and unloading process, follow the tanker within its normal range of movement;

When the loading and unloading arm is in the receiving state, it is locked parallel to the direction of the tank truck's movement, occupying less space;

5. The structure is reasonable, with a very small arm size to meet a reasonable envelope range.

When the bottom of liquefied gas is sealed for loading and unloading, the liquid phase pipeline interface is facing downwards or laterally.
