High temperature steel prefabricated steam directly buried insulation steel pipe is widely used in liquid, gas transmission pipe network, chemical pipeline insulation engineering petroleum, chemical, centralized supply, air conditioning and ventilation pipeline, municipal engineering, etc.

High temperature resistant steel sheath steel insulation pipe is suitable for direct buried prefabricated insulation pipe with conveying medium below 180 ℃. Cogeneration, high-temperature water heating and steam heating all need directly buried insulation pipes with higher temperature resistance requirements. The advantages of high-temperature water for central heating are increasingly recognized by peers in the heating industry. In order to meet the needs of users to transport high-temperature heat-carrying media, we have developed high-temperature insulation pipes.

The use of steel insulation steel pipe temperature range and the use of the environment is extremely wide, even in minus 60 ℃ to zero 60 ℃, can be used safely, in the safe range of effective use, and he will have uneven settlement, relatively strong adaptability, especially in winter construction, will not occur pipe leakage.

The reason why the steel-sheathed steel steam directly buried thermal insulation steel pipe can be directly laid without other protective measures is that the steel pipe should be used as an outer protective layer, which has the characteristics of high strength, not easy to damage and can bear the upper load of the trap. In order to achieve long life, the steel outer sleeve needs anti-corrosion treatment, which ensures the safety of heating pipelines and can be widely used in different temperature environments *, especially suitable for high temperature steam pipeline projects. The sliding bracket and internal fixation in the steam pipeline adopt special material insulation measures to prevent the generation of thermal bridge, so that the temperature control of the outer coating is obtained.
