What material is used for the toluene liquid pipeline conveying acid?
Thread Content
Because toluene is easily charged with static electricity, it is easy to cause problems when using PP pipes to accumulate static electricity. Metal pipes can solve some static electricity problems, but because they are easily corroded by acids, carbon steel and stainless steel cannot be used. Have you ever encountered this situation? Do you have any recommended pipe materials?
You can choose carbon steel lined PP or PTFE lined pipes, and electrostatic bridging and grounding must be done.
Speaking of methane, there is a question. If it is a mixture of hydrogen and methane, can the pressure regulator be made of aluminum alloy? Explanation, this is a low pressure situation, about 10 kilograms!
Steel-lined PP pipes also have problems. The PP layer is not conductive, and strong static electricity will still be generated when toluene flows at a high flow rate. PP pipes with conductive metal wires also have the problem that metal is prone to corrosion.
