PU Pneumatic Pipe

There are many kinds of pneumatic pipes, which are generally produced with PU raw materials, with stable quality, high pressure resistance, weather resistance, wear resistance, zigzag resistance, smooth and flexible pipe body, bright color, high elasticity, winding resistance and small bending radius.

The tube body is smooth and flexible, bright color, high elasticity, winding resistance and small bending radius. Temperature range: - 15 - + 70 ℃.

Product classification

1. Pu pneumatic pipe

2. Pu (polyether) pneumatic pipe

3. Pu (polyurethane) bobbin

4. Pu (polyether) bobbin

difference:

Polyurethane pneumatic pipe is over air type. If it is used for over water, its service life will be affected,

Polyether pneumatic pipe can pass air or water, with more stable physical properties and longer normal service life. It is an ideal material for pneumatic pipe.

The bobbin is wrapped with a layer of fiber in the middle of the common pneumatic pipe. Therefore, the bobbin is more solid, pressure resistant and non explosive than the common pneumatic pipe.

Product selection

What should be considered when choosing the type of plastics for blow molding pneumatic pipe?

The following aspects should be considered in the selection of pneumatic pipe materials.

Whether the wall thickness of the welded blank of the pneumatic pipe can be kept uniform, whether a higher blowing pressure is needed, whether the blowing is uniform, whether the surface of the pneumatic pipe is bright, whether the demoulding is easy, and whether the strength can meet the requirements, etc.

Performance comparison of plastics for blow molding pneumatic pipe. The pneumatic tube formed by blow molding is in thermoelastic state, and its density is smaller than that after cooling and shaping, resulting in shrinkage. For the general size of pneumatic pipe is not strict, forming shrinkage has little effect. But for the pneumatic pipes of specified size, such as some hoses used in precision machines, large shrinkage has a considerable impact. The larger the blowing volume is, the more significant the effect is.

The advantages of extruding and blowing plastic forming pneumatic pipe are less investment in production equipment, simple equipment structure, easy mold manufacturing, high forming of pneumatic pipe during production, uniform temperature control, and various specifications of pneumatic pipe can be formed. The disadvantage is that the wall thickness uniformity of pneumatic pipe is poor.

The advantages of injection blow molding pneumatic pipe are that the plastic pneumatic pipe has good product quality, accurate dimensions, no seams, uniform wall thickness, multi-mode molding production, high degree of automation, which is very suitable for large-scale high-efficiency production of small specifications. The disadvantage is that the investment of equipment and molding die is large, and the operation and production need skilled workers.

Tips for pneumatic pipe

Polyurethane pneumatic hose is suitable for compressed air, ordinary industrial water and non corrosive oil. In order to maintain a long service life, it must be used under rated working pressure and ambient temperature. As the temperature rises, the working pressure should be reduced accordingly. If it exceeds the limit, the hose may break. If the fluid temperature is too high or the fluid is corrosive, the hose may break. If the working environment temperature is too high or there is chemical gas in the working space, the hose may crack. If the hose is stored in a wet place or the storage period is too long, the hose may hydrolyze or age, which may lead to fracture
