The technological process and product characteristics of directly buried insulating pipe:

The direct buried insulating pipe is a rigid polyurethane foam insulating layer filled between the straight seam steel pipe, the high density polyethylene outer sleeve and the straight seam steel pipe and the outer sleeve.

The manufacture of directly buried insulation pipes only needs to set the straight seam steel pipes after rust removal and corrosion protection in the polyethylene bushing, and the two ends are filled with polyurethane foam to fill the gap between the steel pipe and the polyethylene bushing so as to make the spiral steel pipe, casing and insulation layer form a sturdy whole so as to achieve the effect of anticorrosion and heat preservation. The construction process can be stopped on site.

Technological process: steel tube inspection - rust removal and anticorrosion - pipe piercing forming - head repair - finished product inspection - finished product stacking secondary equipment: steel tube buffer platform, pipe diverting unit, transmission line, steel tube preheating furnace, shot blasting machine main machine inspection turntable and unqualified spiral welded pipe to transmission line, fast-forward roller set, tractor, pipe piercing machinery, high-pressure gun launcher, repair platform, Fast-out roller, inspection level Taiwan and so on.

Product features: Direct-buried prefabricated insulating pipes have outstanding advantages over traditional insulating pipes.

1. Good thermal insulation function, heat loss is only 25% of the traditional pipe, temporary operation can waste a small amount of power, significantly reducing power costs.

2. It has strong ability of waterproofing and corrosion resistance. It can be buried in the world or water indirectly without additional pipe trenches. It is simple and quick to construct, and its comprehensive cost is low.

3. It also has good corrosion resistance and impact resistance at high temperature, and can be buried in the frozen soil indirectly.

4. The service life can reach 30-50 years. Correct installation and operation can make the maintenance cost of the pipeline network very low.

5. It can set up alarm fragments, automatically monitor the leakage of pipeline network, accurately indicate the fault status and automatically alarm.
