Types of thermal insulation pipes
What are the main categories of thermal insulation pipeline steel pipes?
There are many new thermal insulation materials in domestic thermal insulation pipes, among which the most commonly used thermal insulation pipes are rigid polyurethane foam. There are also many different materials for the components of thermal insulation tubes. This article will introduce four types of thermal insulation tubes:
1. Prefabricated polyurethane direct buried insulation pipe
External material PE jacket tube, can be customized according to the on-site media delivery environment, the price is low, non-toxic and odorless, no dust and falling objects, flame retardant, no harmful substances are released after working for a long time at a medium temperature below 120 ℃, and the softness is good , Waterproof and moisture proof, acid and alkali corrosion resistance, excellent heat preservation effect.
2. FRP polyurethane insulation pipe
The external material glass fiber reinforced plastic is installed overhead, without trenching and buried, simple and convenient construction, non-toxic and odorless, no dust and falling objects, flame retardant, long-term exposure to exposed space will not oxidize, waterproof and moisture-proof, acid and alkali corrosion resistance, Crash resistance.
3. galvanized iron skin polyurethane insulation pipe
The external material of the enterprise's heat source transportation is made of hot-dip galvanized iron sheet. This kind of galvanized iron sheet is not afraid of water or light. It adopts spiral forming structure for winding, bending resistance, and good acceptance of combined seam. Longer service life.
4. composite polyurethane insulation tube
The thermal conductivity of polyurethane insulation is very low in insulation materials, so it can reduce the heat loss of the material to a very low limit; because the closed cell rate of polyurethane foam is more than 92%, therefore, polyurethane is used as the insulation layer of insulation pipes , It can not only play the role of heat insulation, but also effectively prevent the penetration of water, moisture and other corrosive liquids and gases, and prevent the growth and development of microorganisms. Polyurethane foam can be firmly bonded to various materials, so as the insulation layer of the insulation pipe, there is almost no need to consider the problem of adhesion of the anticorrosion layer. The adaptation temperature of the polyurethane insulation layer is + 120 ℃ -196 ℃, and it can reach + 190 ℃ in a short time (more than ten hours). If the user needs a long-term temperature of 190 degrees, it can be molded with high-temperature materials according to user needs.
