Knowledge of the installation of polyurethane direct buried insulation pipes

Polyurethane insulation system pipe is a very important and practical direct buried prefabricated insulation pipe enterprise products in the heating and heating impact project, it has a very wide range of uses, and the development has a good thermal insulation quality
.

The pipe walls of prefabricated directly buried polyurethane insulation pipes have no joints compared to other ordinary insulation pipes
.

And for this traditional pipe in the field of industrial technology is still very widely
used.

The function of polyurethane insulation pipe is mainly to transport natural gas, oil, hot water and other fluids
in China.

Both of them can be achieved by studying polyurethane insulation pipes
.

Today, we will share our installation expertise
in polyurethane insulation pipes.

1.
Prepare the prefabricated direct buried polyurethane insulation pipe before installation must complete the necessary preliminary planning
.

2.
Before installation, prefabricated direct buried polyurethane insulation pipe should be checked before installation whether it is because of poor transportation or storage and transportation that leads to anti-corrosion outside the pipeline or the destruction
of core components.

3, the storage of prefabricated direct buried polyurethane insulation pipe should be stored in flat, non-rigid, solid debris such as gravel
.

After storage, it should be firmly placed on the cushion layer to prevent heat and fire
.

The pipe stacking shall not exceed 1 meter
.

5.
Before verifying the installation of prefabricated direct buried polyurethane insulation pipelines, please carefully check the company's product pipeline drawings and the pipeline construction plan of the design institute, and check the location and direction
of the pipelines.

And strictly follow the product line diagram and product number to complete the pipeline installation
.

5.
The installation of the design direct buried insulation pipeline should be completed according to the design development requirements of the students, and the construction inclination of the pipeline should be consistent with the teaching design; In pipe segments that must be compensated by an axial bellows compensator (prohibited in corners), if we have to add some additional elbows, we must be able to pass the inspection
of our own designers.

6.
Lifting ring
should be used when hoisting the insulation pipe.

7.
The prefabricated prefabricated polyurethane insulated steel pipe can be hoisted into the groove for installation, or two or more
can be hoisted after installation and welding.

When the welded pipe cross-section is long, two or more cranes should be used to lift the buried pipe and select the lifting position
according to the balance conditions.

It is lifted with a wider soft sling and should remain stable to prevent the pipe from being fed directly into the groove
.
