Product Details
Material
Q 235 steel, # 20 steel
Process
cold rolling
Main Parameters
compared with the traditional cold drawing and honing process,
the precision of the inner holes is 0-0.05mm,
smoothness is between Ra~0.8to Ra~1.6,
the same section thickness deviation is �±0.20mm,
within the ellipticity of 0.05mm,
Straightness is 0.2mm/m.
The shell of cold rolled forming pump can be used directly without honingï¼?in this way a great deal of processing cost is saved and work efficiency is improved.
Application
It is suitable for submersible pump units of various geological conditions.
