Polyurethane Foam Insulation Pipe brief introduction
Polyurethane Foam Insulation Pipe refers to a pipeline that has been equipped with thermal insulation to reduce heat transfer between the transported contents and the surrounding environment.
Insulated pipelines are used in various industries and applications to maintain the temperature of fluids (liquids or gases) being transported, prevent condensation, improve energy efficiency, and protect the pipeline from temperature-related stress.

Pipe insulation what material good ?
Foam tubing, available in different sizes, designs, and structures, is used for pipe protection. The important factor to take into account when selecting foam tubing is the material used to produce it. This material-type's thermal insulators are usually made of porous materials — glass or mineral wool, rubber, polystyrene, polyurethane, or polyethylene foam.
Polyurethane-foam tubing is often used to insulate central heating and domestic-water pipelines. This material is resistant in the temperature range -50°C to 135°C, and has a low heat-transfer coefficient. Such a thermal insulator is rigid, and protects pipes from damage. Tubing made of polyurethane foam is distinguished by its high level of resistance to chemicals. It comes in a soft, hard, and super-hard versions.
Polyethylene foam is also well-suited for insulating straight pipelines. It is almost totally water-repellent, highly flexible, and easy to apply to pipes. It is resistant to temperatures ranging from -80°C to 105°C. A thin polyethylene foam will protect pipes from heat-escape.
Both polyurethane and polyethylene foam tubing protects pipes against contact with the ground, guarding against plaster damage. Moreover, its application eliminates the noise associated with the system’s operation. Thus, foam tubing prevents heat-escape and eliminates cost increases. It, moreover, improves safety, and provides greater comfort for residents.
