Polyurethane insulation pipe products are widely used, but now our life can not do without the use of polyurethane insulation pipe products, why is this? Because in our daily life, the pipes conveying water and other media are often used in polyurethane insulation pipes.

Polyurethane insulation pipe as work is mainly used to transport liquid medium, however, if you need to transport for a long time, the temperature of the liquid should not be more than 120, and the highest temperature should not be more than 140, including gas or other hot and cold medium, pu heat preservation pipe low thermal conductivity, heat preservation effect is good, rigid polyurethane foam used as an insulating layer. Polyurethane insulation pipe has high strength, anti-aging, good corrosion resistance, good sealing performance, waterproof, and impermeable, polyurethane insulation pipe adopts advanced high-pressure polyurethane mixing foaming machine, the production of a three-in-one combination. Polyurethane insulation pipe products have good sealing and waterproof performance and are mostly used in areas with high water tables and humidity.

Polyurethane insulation pipes are generally connected in the following two ways:

1. Thermal contraction belt

Raglan sleeve joint, such joint casing with prefabricated insulated pipe material and density of the same polyethylene casing pipe, the polyethylene with heat shrinkable belt joint casing connected to the head of the seal, guarantee the water tightness of joint, and then on the joint sets on the foaming hole on joint foam, foam with high-density polyethylene block, and the patch or hot melt welding methods will foam hole closed.

2. Electric melting sleeve

The welding method uses the sleeve embedded with resistance wire, the hot melt sleeve, and the outer sleeve tightly tied together with binding, and then switch on the power to start welding, preset welding time, automatic power off after the welding is finished, until the casing completely cooled, take off the binding, such a joint structure is simple, the connection is firm.
