As the name implies, "crane pipe" is a kind of pipe which can stretch and move like crane neck, which is mainly composed of fixing, rotating, operation, balance and so on. It is mostly used for liquid loading and unloading of petroleum and chemical wharf, also known as fluid loading and unloading arm. 

The product adopts rotating joint to connect with rigid pipe and elbow to replace the old hose connection, which has the characteristics of high flexibility and long life.

Are crane tube manufacturers the same? 

There are many points of attention when doing crane pipe selection, regular manufacturers will understand and provide "crane pipe data table" in detail, chemical designers will be based on the field data for design selection and drawing confirmation. 

Crane pipe manufacturers are intermingled, as pressure pipeline "special equipment installation and renovation license" and "special equipment design license" manufacturers, must be based on qualifications and industry reputation to choose.

The crane pipe is mainly composed of fixing, rotating, operation, balance and other mechanisms and tubing. 

Among them, the rotary mechanism (rotary joint) is meticulously manufactured with forged steel or aluminum alloy, with multiple ball bearings and stainless steel special sealing ring, which has the advantages of flexible rotation, reliable sealing performance and durability.
