Characteristics of directly buried steam pipe with steel sleeve:
High temperature resistant thermal insulation layer, layer and elastic seal. Sytdin is the implementation standard of this kind of anticorrosive and thermal insulation steel pipe. There are many ways of retaining layer (such as high density polyethylene, glass fiber reinforced plastic protective layer), but all of them can ensure the integrity, sealing and waterproof performance of the joint
There are three ways of directly buried insulation pipe with steel sleeve, including cold installation, hot prestressed installation and compensator installation. High density polyethylene shell (or FRP shell) has excellent anticorrosion, insulation and mechanical functions

The construction method of heat preservation and anti-corrosion direct buried heat preservation pipe of steam pipeline is a kind of steel pipe. There are two methods of foam construction and insulation tile construction.
