Housing and casing for oil electric submersible pump ,motor ,protector and sepetator
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.
