Knowledge Base

Q

Prefabricated buried polyurethane insulation pipes have low thermal conductivity; It does not deteriorate when exposed to moisture and has good heat resistance, Long service life and other advantages, Not only does it have significant social and economic benefits, but it is also a powerful measure for heating energy conservation.

Q

1. Steel sleeve steel direct buried insulation pipe, welded steel pipe for low-pressure fluid transportation (GB/T3092-1993), also known as general welded pipe, commonly known as black pipe. It is a welded steel pipe used for transporting generally low-pressure fluids such as water, gas, air, oil, and heating steam, as well as for other purposes. The wall thickness of steel pipes is divided into ordinary steel pipes and thickened steel pipes; The form of the takeover end is divided into non threaded steel pipes (light)

Q

What is the function of prefabricated buried steam insulation pipe     Prefabricated directly buried insulation pipes, also known as prefabricated insulation pipes, are divided into two types: plastic sheathed steel insulation pipes and steel sheathed steel insulation pipes (used as steam pipelines). Prefabricated directly buried steam insulation pipes can be directly buried in frozen soil layers of 0.6-1.2. Rice (so people are accustomed to calling it directly buried).
