Advantages of Insulation Pipes and Construction Specifications (Part 1)

Advantages of thermal insulation pipe:

1. Good insulation performance, heat loss is only 25% of traditional pipes, long-term operation can save a lot of energy and significantly reduce energy costs.

2. It has strong waterproof and anti-corrosion ability. It can be directly buried in the ground or water without laying pipe trenches. The construction is simple and quick, and the overall cost is low.

3. It also has good corrosion resistance and impact resistance under low temperature conditions, and can be directly buried in frozen ground.

4. The service life can reach 30-50 years, and the correct installation and use can make the pipe network maintenance costs. Polar rigid polyurethane insulation pipes are widely used in direct buried projects such as urban heating, electric heating, water insulation, oil pipelines . It has many advantages such as environmental protection and energy saving, anticorrosive insulation, antifreeze and cold resistance, and economical beauty.

It is precisely because of these outstanding advantages that the application of insulation pipes will become more and more widespread, so the common problems in application are nothing more than installation and construction.

Insulation pipes have good mechanical and thermal insulation properties. Generally, they can withstand temperatures up to 120°C. They can be modified up to 180 ° C through combination with other insulation materials.

Thermal Insulation Pipe

The thermal insulation pipe factory reminds you: From the perspective of quality problems in engineering practice, you should pay special attention to several issues in design and construction:

One

In the design and construction, we must really understand the direct buried method of heating pipelines. There are paid direct buried methods and unpaid direct buried methods. We must really grasp the working principles, characteristics and application occasions of the two methods in order to design Reasonable selection, safe, reliable and economical construction.

two

Before the construction, the manufacturers who produce high-quality insulation pipes and buried pipes must be investigated. After entering the site, they should be inspected carefully and the unqualified insulation pipes should be rejected.

three

In the construction of directly buried insulation pipes, welding is a pipe fitting work to ensure the quality of the project.

four

With fixed brackets, the construction quality of various well chambers directly affects the engineering quality and the service life of the pipeline. If the well chamber is not waterproof, the components will be damaged due to water infiltration. Therefore, construction should be done carefully to ensure construction quality.

Fives

Attention must be paid to the compression of directly buried pipelines. Under the conditions of compression, the water is first exhausted and the air is exhausted, and then it is done in two steps: 1 Strength test: After the pressure in the pipeline is increased to 1.5 times the working pressure, the pressure is stabilized for 10 minutes No leakage inside. 2 Tightness test: When the pressure in the pipe is reduced to the working pressure, the welding seam is beaten one by one around the welding seam with a 1kg hammer, and there is no leakage within 30 minutes and the pressure drop does not exceed 0.2 atmospheres.
