: >Introduction to direct buried insulated pipes:
: > Direct buried insulated pipes
: > Also known as a tube in a tube, it is composed of a two-step process and is composed of a high-density polyethylene outer protective layer, polyurethane rigid foam insulation material and steel pipes. The insulation layer material is rigid polyurethane foam with a density of / to /, which fully fills the gap between the steel pipe and the casing, and has a certain bonding strength, forming a strong bond between the steel pipe, the outer casing and the insulation layer. overall.
: >Composition of direct buried insulated pipes:
: >Working steel pipes: Slit steel pipes, seamless steel pipes, and double-sided submerged arc spiral welded steel pipes can be used according to the requirements of the transmission medium.
: >Insulation layer: made of rigid polyurethane foam.
: >Protective shell: made of high-density polyethylene or fiberglass.

: > Performance of direct buried thermal insulation pipe:
: > Directly buried thermal insulation pipe
: > It has good mechanical properties and thermal insulation properties, and can usually withstand high temperatures. It can withstand high temperatures (℃) or combined with other insulation materials, and is suitable for insulation projects of various cold and hot water high and low temperature pipelines.
: >Applications of Directly Buried Insulated Pipes:
:>Directly Buried Insulated Pipes are widely used in liquid and gas transportation pipeline networks, chemical pipeline insulation projects, petroleum, chemical industry, central heating networks, central air conditioning and ventilation Pipelines, municipal engineering, etc. Directly buried thermal insulation pipe is a kind of thermal insulation pipe with good thermal insulation performance, safety and reliability, and low engineering cost. Effectively solves the problem of high temperature heat loss in urban centralized heating. Directly buried insulated pipes not only have advanced technology and practical performance that are unmatched by traditional trench and overhead pipes, but also have significant social and economic benefits, and are also a powerful measure for heating and energy saving.
: >Future development of directly buried insulated pipes:
: > Directly buried insulated pipes have become a relatively mature and advanced technology in some developed countries abroad. In the past decade or so, our country's heating engineering technicians have digested and absorbed this advanced technology and are promoting the development of domestic pipe network laying technology to a higher level.
