Polyurethane insulation pipe rust treatment

Now with the progress of The Times, polyurethane insulation pipe is also gradually used more and more, and then I will talk about the rust elimination of polyurethane insulation pipe, and to explain in detail.

Anti-rust removal of polyurethane insulation pipe

The surface treatment of polyurethane insulation steel pipe is mainly mechanical elimination, including shot blasting and sandblasting, shot blasting uses indoor air and high pressure water according to a special nozzle, so that the abrasive in the form of rapid circulation, impact and friction

In this way to remove the steel layer of rust, oxide, pollutants and accessories, after elimination, the steel is not easy to fade, and will produce a suitable degree of cleanliness and finish.

For boiler and petroleum machinery companies that consume a lot of steel, they generally use the sand blasting process, under the function of high-speed rotating cast head leaves! The abrasive is thrown onto the steel layer at a large radial and radial velocity to achieve the goal of eliminating debris.

In addition, we can also use high-pressure sewage treatment and high-pressure water sand removal and other methods, in view of the method of cleaning fast, high efficiency

Therefore, the overall economic benefits are more significant, can effectively increase the use of polyurethane insulation pipe, therefore, in the progress of recent years, the scope of use is more and more wide, but for different seasons, storage forms are not the same

Summer temperature changes too fast, although polyurethane insulation pipe has excellent waterproof and anti-corrosion characteristics, but must go out in the sunny, in the heavy rain temperature to avoid going out, or use plastic sheet to cover the pipe

In addition, the pipeline is easy to roll in the car, can be stabilized with a rope, but pay attention to the stability strength, do not have to leave marks, or even damage the pipeline level, affecting the use of the pipeline.

Polyurethane insulation pipe construction steps

The on-site joint insulation of polyurethane insulation pipe should be carried out after the test pressure is qualified. This work is necessary for the construction of polyurethane insulation pipe. The insulation layer has two methods of on-site foaming construction and insulation tile construction, no matter which method is used, there can be no annular space, cracking, delamination and other shortcomings.

There are many ways to maintain the layer, but the integrity and tightness of the joint must be ensured. The field temperature of the interface in the operation room should be maintained at more than 10 ° C, not less than 5 ° C. Therefore, it is not suitable for joint treatment in winter. Joint treatment should not be carried out on rainy days.
