Magnesium Steel Insulating Pipe Supports Magnesium steel insulating pipe supports with special requirements are referred to as "pipe-shoe," regardless of whether they are for insulation (or cooling). They can be categorized into sliding, fixed, and guiding types. Regardless of the choice, the pipe support itself remains unchanged; the only variation is in the connection between the pipe support and the steel structure or bracket. Typically, sliding and guiding types of pipe supports use PTFE plates in sliding friction with each other, or white steel plates with PTFE plates, to reduce the friction coefficient. This lowers the binding stress on the pipeline from the pipe架 during deformation or displacement, and also aims to minimize relative movement between the pipe support and the pipeline. The polyurethane foam consists of thousands of extremely small, uniform, and independent cells, forming a three-dimensional honeycomb structure. It boasts low thermal conductivity, high compressive strength, and low water absorption, making it superior to asphalt wood products and other types of cushioning materials. It is an ideal material for deep cryogenic pipeline supports, saddles, and low-temperature equipment pads. It is used domestically and in North America and Europe for pipeline supports, suspension brackets, and pads in petrochemical bases, LNG liquefied gas plants, cold chain bases, and central air conditioning systems.
