304 pipeline support issues
Thread Content
The pipe rack is made of carbon steel; the 304 pipes need to be separated from the pipe rack. What is a good material to use for this separation? Polytetrafluoroethylene is too expensive; is there anything else?
If one can afford a group of top-quality horses, all that’s missing is saddles and cushions; would it work to use PVC for that purpose?
Place a stainless steel arc plate between the pipe and the pipe support
That makes a lot of sense. Is there a problem of chloride ion corrosion when using PVC?
The cost of this is higher than that of using polytetrafluoroethylene, and it also requires welding
Is it the gasket between the pipe support and the pipeline?
It can be separated using PE or PP.
I have a question. I’ve encountered this situation before: the pipeline is made of carbon steel, but the customer wants the valve body to be made of stainless steel. For the flanges used in connection, it’s preferable to use those made of the same material as the pipeline, that is, carbon steel flanges. However, the design team says that corrosion can occur between carbon steel flanges and stainless steel valve bodies, and they insist that we use stainless steel flanges. But won’t those flanges still need to be welded to the carbon steel pipeline, thereby preventing corrosion? Are there usually any default rules for this?
