Description :

　　The key to polyurethane insulation pipes lies in insulation, and their important role is insulation. Being able to provide insulation is crucial. The insulation layer is tightly bonded to the outer skin of the steel pipe, isolating the infiltration of air and water and providing good anti-corrosion effect. At the same time, its foam pores are all closed, and its water absorption is very low. The high-density polyethylene shell and fiberglass shell both have good anti-corrosion, insulation, and mechanical properties. Therefore, the outer skin of the working steel pipe is difficult to be eroded by external air and water.

　　Choosing this product also requires an understanding of its specific performance characteristics, as different sizes, specifications, and parameters require different installation environments for polyurethane insulation pipes. Especially under temperature differences, it may cause some thermal expansion and contraction. Therefore, we need to take this into consideration during the installation and construction process, especially when installing in some special environments, which also requires special attention!

　　Choosing polyurethane insulation pipes is a very important issue in many heat source transportation projects. However, the mixed phenomenon of good and bad in the insulation pipeline industry often blurs the line of sight, leading to many problems when choosing polyurethane insulation pipes. Today, Fulesi will take you to understand the purchasing misconceptions of polyurethane insulation pipes that must be known.

　　1、 Don't let low-priced polyurethane insulation pipes blind your eyes;

　　There are qualified and unqualified polyurethane insulation pipes. Generally, regular polyurethane insulation pipe manufacturers produce guaranteed qualified products, while irregular polyurethane insulation pipe manufacturers use inferior raw materials to produce polyurethane insulation pipes in order to reduce costs and cater to some buyers who blindly pursue the price of polyurethane insulation pipes. However, the quality is really not commendable. Once inferior polyurethane insulation pipes are selected, not only will the project be difficult to repair in the future, but the price loss will also be greater.

　　2、 Don't just care about the thickness of the working steel pipe for polyurethane insulation pipes;

　　When purchasing polyurethane insulation pipes, buyers hope to buy high-quality ones. Some people blindly believe that the thicker the working steel pipe, the better the quality. This is one of the common misconceptions when purchasing polyurethane insulation pipes. The thickness of the working steel pipe does not necessarily represent the quality of the polyurethane insulation pipe. Overly thick working steel pipes can actually affect the durability of the polyurethane insulation pipe. But I don't understand the precautions for engineering construction. Even if the quality of polyurethane insulation pipes is good, the quality of the project after construction cannot be guaranteed.

　　The advantage of polyurethane insulation pipes is that they are relatively lightweight. However, we know that there may be many problems when installing the product because during the installation process, if we do not understand the performance advantages of the product, it will result in our installation being unable to reach a stable level. Firstly, during the installation process, we must pay attention to understanding the characteristics of polyurethane insulation pipe material, because polyurethane material itself is quite special, and we need to pay attention to this special material during use. It is better to communicate with the manufacturer and see what specific requirements they have for this product! Some manufacturers have installation guidance requirements for their products, and through these installation and usage manuals, we can also have a certain understanding of the overall performance of the product!

　　First, let's know the full name of polyurethane insulation pipe: high-density polyethylene plastic protected polyurethane foam prefabricated directly buried insulation pipe. The structure of polyurethane insulation pipe: working steel pipe, polyurethane insulation layer, and polyethylene plastic outer protective pipe, which are sequentially combined outward through equipment. The development and application of polyurethane insulation pipes are receiving increasing attention from countries around the world. After the 1970s, foreign countries generally focused on the consumption and application of insulation pipes, striving to significantly reduce energy consumption, thereby reducing environmental pollution and greenhouse effect. The insulation industry abroad has a long history, and new insulation materials are also emerging from time to time. Don't underestimate the contribution of insulation materials to energy conservation and emission reduction. In the development goal of building energy conservation, the contribution rate of building energy conservation should reach 20%, which means saving 120 million tons of standard coal. Therefore, polyurethane insulation pipes are an important factor affecting energy conservation. Before 1980, the development of insulation pipes in China was very slow, and the few insulation factories could only consume a small amount of publicly buried insulation pipes. However, after more than 30 years of effort, especially after nearly 10 years of rapid development, many products in China's insulation industry have gone from scratch, from single to diversified, from low to high quality, and their applications have become increasingly common.
