Hello, experts! Do pipe supports and hangers require gaskets?
This post was last edited by Shutong on 2022-5-8 at 14:18. Gaskets are not required for metal pipes in support and hanger systems. A soft cushion such as plastic tape or rubber should be placed between the plastic pipe and the metal clamp to prevent damage to the pipe surface.
It can’t be generalized; for some supports and hangers, gaskets still need to be considered. Gaskets serve various functions, such as insulation, heat insulation, and preventing rust.
It depends on the specific situation; if it’s stainless steel pipes and carbon steel supports, then it’s definitely necessary
When stainless steel pipes come into direct contact with carbon steel supports and hangers, chemical and electrochemical corrosion is likely to occur. The \"Code for Construction and Acceptance of Industrial Metal Piping Projects\" (GB50235) and the \"Safety Technical Inspection Regulations for Fixed Pressure Vessels\" TSG-R700402009 stipulate that stainless steel and non-ferrous metal pipes shall not come into contact with carbon steel pipes. When the substrate is carbon steel, stainless steel pipes in direct contact with carbon steel are prone to chemical and electrochemical corrosion. In such cases, gaskets need to be installed between the carbon steel brackets and hangers for isolation; the materials for these gaskets can include rubber, asbestos, and other similar materials.
