Since the birth of polyurethane synthetic data in the 1930s, polyurethane foamed insulation pipe has been developed rapidly as an excellent thermal insulation material. Its application scope is becoming more and more widespread. It is also widely used in various heating, refrigeration, oil and steam transmission pipelines because of its cumbersome construction and remarkable energy-saving and anti-corrosion effect. It is widely used in various heating, refrigeration, oil and steam pipelines. Almost in the shortest hey, love you, so that all businessmen can control the heat preservation process on the left side of time. Successfully becoming a high quality feature and choice that most of the current business personnel are rare in comparison with. Prefabricated polyurethane insulating pipes should have low thermal conductivity, no metamorphosis, good heat resistance, no corrosion to metals, light weight and more voids, with certain mechanical strength, no damage when subjected to external forces, easy processing, low cost and other characteristics. Commonly used thermal insulation materials include: shrinkage perlite and its products, glass wool and its products, rock wool products, microporous calcium silicate, aluminum silicate fiber products, foam plastics, foam asbestos and so on.

The insulating layer of steel-sheathed steel steam insulating pipe is usually made of lightweight and durable glass fibre with average slenderness and elasticity and special high-temperature binder. The insulating layer of steel-sheathed steel insulating pipe is made of high-temperature resistant glass wool with excellent thermal insulation performance. The insulating layer needs to be insulated by more than two layers. The transverse and longitudinal seams of the insulating layer are overlapped by staggered seams. The insulating layer is coated with a reflective aluminium foil on the outside. Effectively reduce the heat loss of the pipeline. Water-repellent aluminium silicate blanket/fiber felt can be used as the first layer of insulation layer to meet the requirements of high temperature resistance.
