Knowledge Base

Q

In the field of industrial insulation, it is crucial to choose high-quality prefabricated directly buried foam insulation pipes. Firstly, ensure that the products come from reputable manufacturers such as "XX brand", which is known for its strict quality control and honest operation. Secondly, focus on the core performance of the product: select high-density polyurethane foam material to ensure good thermal insulation performance; The pipe body is made of corrosion-resistant and high-pressure resistant materials

Q

Prefabricated polyurethane directly buried thermal insulation pipe can play a good anti-corrosion role because the polyurethane rigid foam thermal insulation layer is closely bonded to the steel pipe skin, which can isolate the infiltration of air and water. At the same time, its foam pores are all closed, and its water absorption is very low. The high-density polyethylene shell and fiberglass shell both have good anti-corrosion, insulation, and mechanical properties.

Q

Polyurethane prefabricated buried foam insulation pipeline is a composite pipeline composed of working steel pipe, polyurethane insulation layer, and high-density polyethylene (HDPE) outer protective pipe. Working steel pipes are used to transport high-temperature liquids or gases, and polyurethane insulation layers provide excellent insulation performance to reduce heat loss, while HDPE outer protective pipes play a role in waterproofing, moisture resistance, and mechanical protection
