Consumer Specification for Direct Buried Black Jacket Insulation Pipe Manufacturers

Function of directly buried insulating pipes: The directly buried insulating pipes have good mechanical function and thermal insulation function. They can withstand low temperature 120 ~C under normal conditions, and can withstand low temperature 180 ~C when combined with other insulating materials. They are suitable for all kinds of insulating projects of cold and hot water pipelines.

Use of directly buried heat preservation pipes: directly buried heat preservation pipes are widely used in liquid and gas pipeline network, chemical pipeline heat preservation engineering petroleum, chemical industry, central heating network, local air conditioning and ventilation pipeline, municipal engineering, etc. Direct buried insulation pipe is a kind of insulation pipe with good thermal insulation function, safety and reliability, and low cost. Invalid treatment of low temperature heat transfer between 130 ~600 in urban central heating. Directly buried insulation pipe not only has advanced technology and applicable function which is difficult to compare with traditional trench and overhead pipeline laying, but also has obvious social and economic benefits, and is also a weak measure of heating energy saving.

Rare achievements and treatment methods in construction of directly buried insulating pipes:

1. The starting speed of directly buried insulating pipes is slow; this phenomenon usually appears in the construction in autumn and summer or at night, due to the sudden drop in temperature or low temperature. The environmental temperature and black material temperature can be reduced to be treated. Usually, the temperature of black material is raised to 30-60 C, and the ambient temperature is raised to 20-30 C.

2. The starting speed of directly buried insulating pipes is fast; this scene usually appears in spring and winter or midnight construction, because the temperature suddenly drops and the temperature is too low. Black material can be cooled with cold water or left outside at night to cool naturally to prevent direct sunshine.

3. The burial strength of the directly buried insulation pipe is small and the foam is soft. This scene is caused by the imbalance of color materials. The proportion of black materials can be increased appropriately (1:1 - 1.05).
