Magnesium Steel Insulating Pipe Hangers - Special requirements for magnesium steel insulating pipe hangers, those used for thermal insulation (or cooling) are referred to as pipe-shoes. Regardless of insulation, they can be categorized into sliding, fixed, and guiding types. Regardless of the choice, the hanger itself remains unchanged; only the connection between the hanger and the steel structure or bracket varies. Typically, sliding and guiding hangers use PTFE plates for sliding friction, or white steel plates with PTFE plates, to reduce friction coefficients, decrease the binding stress on the pipe from the support structure during deformation or displacement, and minimize relative movement between the hanger and the pipe. Polyurethane foam is composed of thousands of extremely small, uniform, independent cells, forming a three-dimensional honeycomb structure. It has low thermal conductivity, high compressive strength, and low water absorption, boasting superior properties that are unmatched by asphalt wood products and other types of padding materials. It is the ideal material for deep-freeze pipe hangers, saddles, and pads for low-temperature equipment. It is used domestically and in Europe and America for pipe hangers, suspension brackets, and pads in petrochemical bases, LNG liquefied gas plants, cold chain bases, and central air conditioning systems.
