Insulation pipe, buried pipe insulation, pipe insulation jacket black spiral steel pipes including straight seam steel pipe and seamless steel pipe. Outer layer of black polyethylene material called black jacket insulation. High pressure foaming machine with the cavity between the steel pipe and the outer protective layer is formed in a one-time injection of a rigid polyurethane foam stock solution is made, and then processing the polyethylene surface of the steel pipe, forming the outermost layer of the protective layer. High temperature corrosion heating polyurethane insulation, polyurethane foam insulation pipe buried national standard engineering practice in terms of quality problems arise, you should pay particular attention to the following issues in the design and construction: one, in the design and construction must be true Understanding Buried way into heating pipes have compensated and uncompensated burying burying two ways, really two ways to master their works, characteristics and applications, pipe insulation, so a reasonable choice in the design, Construction on the safe, reliable and economical. 1. We must first grasp the concept: There are ways to compensate Buried polyurethane insulation manufacturers, is by pipeline natural compensation and compensation (such as squares and bellows compensator) to solve the thermal elongation of the heating duct pipe insulation tubes, so that the thermal stress the minimum; no compensation Buried, simply put, is the pipeline without any compensation measures when heated, but by the strength of the pipe itself to absorb thermal stress.
