The large crane pipe is widely used in petrochemical operation. The rotating joint of the crane pipe is made of alloy steel and stainless steel, precision CNC machine tools are selected, and the supporting structure of the double raceway is included, which can accept the harsh axial, radial and torque loads. 

Tumble active, reliable, no leakage. 

Sealing ring structure together, the selection of wear-resistant, corrosion-resistant reinforced polytetrafluoroethylene data PTFE, embedded stainless steel skeleton, the sealing surface is polished, the sealing function is superior and reliable.

Crane tube manufacturers can add posts, airtight, acousto-optic alarm equipment, heating and thermal insulation equipment, stainless steel data, hydraulic submersible pump, and electric submersible pump according to customer needs. 

Crane pipe is a kind of equipment which is used for liquid medium transmission between tank truck and trestle storage and transportation pipeline, which is connected with pipe by rolling, activating and sealing rotating joint. 

Key parts of the rotating joint, the selection of precision CNC machine tool processing, built-in double raceway support structure, rolling active, concise and reliable. 

The outer ring selects alloy steel, the inner ring selects stainless steel or lined polytetrafluoroethylene to ensure that it can be used in high temperature, low temperature and strong corrosive medium.
