Stainless steel water pipe wall thickness.
Requirements for water pipe wall thickness The factor for wan thickness is differents. we can not consider simply from the perspective of the laboratory conditions. The definition of water pipe wall thickness in national standards have been used and prefect for several decades by Germany and Japan. Choice of wall Thickness is to choose reliability...
stainless steel press fitting thickness requirements.
Pipe is the key component of pipeline .The reliability of Connecting is crucial point of using life for water pipe .So, It's not regulate the negative tolerance for pipe fitting wall thickness in GB, but regulate the minimum wall thickness to avoid inadequte of pipefitting wall thickness of material must be a higher grade,or else will inevitably cause insufficient thickness to less than the national standard and affect life. ..
