A Brief Discussion on the Development and Application of Polyurethane Insulation Pipes With the continuous development of the social economy, the application of polyurethane insulation pipes in our production and life is becoming increasingly widespread and favored by users. Below is a brief introduction to the development and application of polyurethane insulation pipes.

Polyurethane insulation pipe is not only used for transporting fluids and powdery solids, exchanging heat energy, manufacturing mechanical parts and containers, but it is also an economical steel material. Using polyurethane insulation pipes to manufacture building structural grids, pillars, and mechanical supports can reduce weight, simplify construction, and save costs.

With the continuous development of strip rolling production and the advancement of welding and inspection technology, the demand for welding polyurethane insulation pipes is gradually increasing due to the continuous welding of seams. The development of the chemical industry is driving the polyurethane insulation pipe industry in terms of variety, output, and quality.

All equipment on the entire production line has the function of networking with computer data acquisition to achieve real-time data transmission, and the technical parameters in production are controlled by the control room.

During the forming process, the steel plate undergoes uniform deformation, with minimal residual stress and no scratches on the surface. The processed spiral steel pipes have greater flexibility in the size specifications of diameter and wall thickness, especially in the production of high-grade thick walled pipes, especially small and medium-sized thick walled pipes, which have advantages in other processes. Users can have more requirements in terms of spiral steel pipe specifications.

2. Adopting the double-sided submerged arc welding process with X in, welding can be achieved at the optimal position, which is less prone to defects such as misalignment, welding deviation, and incomplete penetration, and easy to control welding.

3. Conduct a 100% inspection on the steel pipes to ensure that the entire production process is under effective testing and monitoring, effectively guaranteeing the quality of the products.

Rigid polyurethane has many excellent properties and is widely used in the field of thermal insulation in Europe and America. About 49% of developed insulation materials in Europe and America are polyurethane materials, while in China, this proportion is less than 20%. Therefore, there is still a lot of room for the development of polyurethane insulation pipes in China.

Insulated pipes are suitable for transporting various media within the range of -50 ℃ to 150 ℃. They are widely used in centralized heating, cooling, and hot oil transportation, as well as insulation and cooling projects in industries such as warm rooms, cold storage, coal mines, petroleum, and chemical engineering.

The outstanding advantages of polyurethane insulation pipe The polyurethane insulation pipe is made of rigid polyurethane foam, which can fully fill the gap between the steel pipe and the sleeve, and has a certain bonding strength, so that the steel pipe, the outer sleeve and the insulation layer form a solid whole. The insulation performance of this raw material's insulation pipe is good, with extremely low heat loss, and long-term operation can greatly save energy.

Polyurethane insulation pipes run more smoothly than traditional insulation pipes and can significantly reduce energy costs. And it has strong waterproof and anti-corrosion capabilities. High impact resistance, can be directly buried in frozen soil underground, and ensures that the insulation pipe will not break. Polyurethane insulation pipe is currently the most commonly used insulation material, with an extremely long service life.

The insulation layer is made of rigid polyurethane foam with a density of about 60kg/m3 to 80kg/m3, which can fully fill the gap between the steel pipe and the casing, and has a strong bonding strength, making the three main layers of steel pipe, outer casing and insulation layer form a solid whole. The foam of foamed thermal insulation steel pipe has outstanding mechanical and thermal insulation functions. Generally, it can withstand 120 ℃. After modification or combined with other thermal insulation materials, it can withstand 180 ℃.
