Seeking advice on the selection of valves and insulation materials for the acetic acid unloading feed line
Thread Content
For the acetic acid unloading feed line, 316L piping is to be used. Can aluminum silicate be used as the insulation material? Should gate valves be those specified in Part 3 (Valves) of the \"Petrochemical Process Piping Design Manual\" as valves suitable for acetic acid media? Waiting for experts to give some advice. . .
There are electric ball valves on the pipe rows, while gate valves are used in the pump area
Using ball valves results in relatively lower costs
Aluminum silicate can be used, but according to GB/T 16400-2003 \"Aluminum silicate wool for insulation and its products\", clause 5.5.3 requires that the leachate must comply with GB/T 17393-2008 \"Specifications for insulating materials for cladding austenitic stainless steel\". Therefore, the material list should specify that the insulation products purchased must comply with the GB/T 17393-2008 standard.
