China Manufacturer Tight Tolerance Good Roundness Various Material Submersible Motor Housing

China Manufacturer Tight Tolerance Good Roundness Various Material Electric Submersible Motor Housing

The pump stages are housed in a pressure sleeve(housing) made of thigh grade alloy steel.The inside diameter of the housing is isolated from the pumpstages;the outside surface may be treated with a special coating as an added protection from hostile fluid in the well housing.

1.Application

It uses coll rolling process and formed in one step,inner hole precision /-0.05mm, degree of finish Ra0.8~1.6, section wallthickness deviation 0.2mm, ovality within 0.05mm,straightness 0.2mm/m, The cold-rolled housing can be directly assembled and used without honing, which greatly saves the processing cost and improves the working efficiency.
