Steel sleeve steel direct buried insulation pipe is made of high-performance polyether polyol composite material and repeatedly methyl polyphenyl polyisocyanate as materials, which are foamed by chemical reaction. Steel sleeve steel direct buried insulation pipe is used for insulation and cooling engineering of various indoor and outdoor pipelines, centralized heating pipelines, central air conditioning pipelines, chemical, pharmaceutical and other industrial pipelines.
　　
The primary characteristic of steel sleeve steel buried insulation pipe is its service life of up to 30-50 years. The insulation function of the pipe is good, and the heat loss is only 25% of that of traditional pipes. Long term operation can save a lot of power and significantly reduce power costs. Has strong waterproof and corrosion-resistant capabilities, simple and agile construction, and low overall cost.
　　
Common questions in the construction of steel sleeve steel buried insulation pipes? Steel sleeve steel direct buried insulation pipe factory teaches you how to handle it:
　　
1. Slow starting speed of steel sleeve steel buried insulation pipe
　　
This phenomenon usually occurs during autumn, winter, or early morning construction due to sudden drops in temperature or low temperatures. Raise the ambient temperature and black material temperature to handle it. Usually, the temperature of the black material should be raised to 30-60 ℃, and the ambient temperature should be raised to 20-30 ℃.
　　
2. Steel sleeve steel direct buried insulation pipe has a fast starting speed
　　
This phenomenon usually occurs during spring and summer or noon construction, due to the sudden rise in temperature caused by excessive heat. Black materials can be cooled with cold water or naturally cooled outdoors at night to prevent direct sunlight.
　　
3. Steel sheathed steel directly buried insulation pipe foam has low strength and soft foam
　　
This phenomenon is caused by an imbalance in the proportion of non materials. Increasing the proportion of black materials appropriately (1:1-1.05) is sufficient. Be careful not to make the proportion of black materials too large, otherwise it will make the foam brittle and affect its function.
