Motor Housing ,motor casing ,pump housing,protector housing for Submersible Electric Pump
1.Material includes Q234B steel,Q345B steel,45#steel,4130,4135,ASTM A335 T91,T95,TP304,TP316,ASTM A335 P5
Process:Cold rolling process,compared with the traditional cold drawing and honing process
The precision of the inner holes is 0~0.05mm
Smoothness is between Ra~0.8 to Ra~1.6
The same section thickness deviation is +-0.20mm
within the ellipticity of 0.05mm
Straightness is 0.2mm/m
The housing made of cold rolled forming process can be used directly without honing,in this way a great deal of processing cost can be saved and work efficiency is improved.
It is suitable for submersible pump units of various geological conditions.
6.We can manufacture according to your drawing with good quality and to be on time.
