Standards for halogen content requirements in stainless steel contact materials
Thread Content
When chemical industry stainless steel pipes corrode, are there any standards that specify the halogen content in the organic materials in contact with these stainless steel pipes?
What are the standards? Is there a standard number? Does \"below 25 ppm\" refer to a requirement for the operating medium? What I need is information on materials in contact with pipes, such as seals, outer anti-corrosion and insulation materials, etc
