Zheheng steel, specializing in the production of stainless steel
seamless pipe, stainless steel tube, stainless steel U type pipe,
stainless steel bellows tube, stainless steel coil, stainless steel
coil for 15 years, from the storage of raw materials, production
and processing, finished product outbound cengcengbaguan, to ensure
that the environmental protection, safe and reliable.
Special purpose steel pipe and cold rolled steel tube outside
diameter allowable deviation can be used absolute deviation.Wall
thickness tolerance is divided into two types: standardization and
non-standardization.Standard wall thickness tolerance should be
preferred.
Welding steel pipe wall thickness requirement, welding steel pipe
wall thickness allowable deviation,
national standard welded steel pipe wall thickness allowable
deviation table.
