Technical consultation on liquid chlorine pipeline insulation
Thread Content
I would like to ask everyone what materials are used for insulation of liquid chlorine pipelines (at temperatures below 0 degrees), as well as what construction methods are employed I mainly want to understand how it’s done in the industry; please share your insights so we can determine which approach is better.
Insulation materials are generally made of polyurethane foam, which is either prepared on-site or installed in a molded form; professional anti-corrosion and insulation companies will provide appropriate solutions for this. :)
Polyurethane. Now pipes use casings ； The equipment can be sprayed directly, with the thickness determined by how much is sprayed.
Ideal approach: wrap it with 4 flat hollow tubes, with each pair forming a cycle unit, and use a CacL salt solution for cyclic cooling. The periphery is treated with insulating material.
Generally, polyurethane is used to form the tube shell, it is bonded with hippurate, and then waterproof materials are added.
Silicate cotton is wrapped with glass fiber and then coated with asphalt mastic
A layer of quartz sand at the bottom, followed by the spraying of polyurethane, and then a layer of cement on top
