Product features

It has many varieties, generally produced with PU raw materials, stable quality, high pressure resistance, weather resistance and wear resistance.

It is resistant to twists and turns, the tube body is smooth and flexible, the color is bright, the elasticity is high, the bending resistance is fast, and the bending radius is small. Temperature range: -15--+70 degrees.

Product category

1, PU (polyurethane) pneumatic tube

2, PU (polyether) pneumatic tube

3, PU (polyurethane) clip tube

4, PU (polyether) clip tube

The difference:

Polyurethane-type pneumatic tubes are over-air type, such as used to pass water will affect the service life,

The polyether pneumatic tube can be used for over-gas or water, with more stable material properties and longer service life. It is an ideal pneumatic tube material.

The clamping tube is wrapped with a layer of fiber in the middle of the ordinary pneumatic tube. Therefore, the clamping tube is stronger and more resistant than the ordinary pneumatic tube, and is not easy to burst.

Product choice

What should be considered when selecting a plastic type for blown pneumatic tubes?

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

Whether the wall thickness of the pneumatic tube melt parison can be kept uniform, whether a high inflation pressure is required, whether the inflation is uniform, whether the surface of the pneumatic tube is bright, whether the demoulding is easy, and whether the strength can meet the requirements.

The performance of plastics for blow molding pneumatic tubes is compared with wind gauges. The blow molded pneumatic tube is in a thermoelastic state, and its density is smaller than that after cooling and setting, resulting in shrinkage. For pneumatic tubes with generally small dimensions, the molding shrinkage has little effect. However, for a pneumatic tube of a specified size, such as some hoses for precision machines, the large shrinkage has a considerable influence. The larger the volume of blow molding, the more significant the effect.

The advantage of extrusion-inflated plastic forming pneumatic tube is that the investment in production equipment is relatively small, the structure of the equipment is simple, the mold manufacturing is easy, the pneumatic tube is formed at a high speed during production, the temperature control is relatively uniform, and the pneumatic tube of various specifications can be formed. The downside is that the wall thickness of the pneumatic tube is less uniform.

The advantage of injection-inflated pneumatic tube is that the molded plastic pneumatic tube has good quality, accurate size, no joint seam, uniform wall thickness, multi-molded production, high degree of automation, and is very suitable for large-scale high-efficiency of small size. produce. The downside is that equipment and molding molds are heavily invested, and skilled workers are required to operate the production.

Product advantages:

1. Excellent flexibility. Less bending radius and resistance to bending. Has a high elasticity to restore memory effect.

2. Resistance to wear, tear, and impact. Resistant to some non-corrosive chemicals and oils. It can circulate flammable objects and can be welded.

3. It can be incinerated into ash by 100%, which is an environmentally friendly product recognized.

4. Good damping, smooth inner wall, low friction coefficient, high medium passing ability, good flame retardancy, non-toxic and tasteless.

5. Color can be customized as needed, easy to identify the pipeline.

Pneumatic tube use tips

Polyurethane pneumatic hoses are suitable for compressed air, general industrial water, non-corrosive oils. To maintain a long service life, it must be used at rated working pressure and ambient temperature. As the temperature rises, the working pressure should decrease accordingly. If the limit is exceeded, the hose may break. Excessive fluid temperatures or chemically corrosive fluids may cause hose rupture, excessive operating temperature or chemical gases in the work space, which may cause hose cracking, storage in wet locations, or storage periods. Long, it will cause the hose to hydrolyze or age, which may cause cracking.
