Fluid loading arm

Crane tube (land use fluid handling arm some parts description)

Rotary joint presentation

Swivel joints using precision CNC machining, large capacity, flexible rotation, for liquid and gaseous media having the desired sealing effect, can be safely and reliably used at room temperature, low temperature, high temperature, corrosive media, the primary seal and secondary seal and dust seal effective to achieve zero leakage. Rotary joint designed for a variety of structural forms, ranging from a simple structure to internal heating of steel lining PTFE structure, single roller, double and triple raceway raceway. Rotary joint is removable without disassembling the whole arm when replacing the seals, and can be easily replaced. Both sides are flanged rotary joint structure makes repairs, the replacement easier and faster.

Main ring

Main ring made of graphite filled PTFE and specially treated stainless steel liner tension spring cards. Seal with PTFE, wear resistance, good sealing effect, anti-aging, and other characteristics, in order to increase the elastic lining snap ring, when after long-term operation of the sealing surface wear, snap to a certain extent realized within the scope of compensation.

Secondary seal

And the main seal structure similar to the axial direction of the opening, has a good compensation performance.

Dust seal

Dust seal and secondary seal similar to prevent moisture and dust from entering the raceway.
