Only standard Sandblasting pipe The product can make users feel relieved. Next, let's talk about her technical standards.

In terms of service temperature, Sandblasting hose The temperature of is generally - 20 ℃ - 70 ℃.

In terms of material and structure, the sandblasting pipe should have the following composition.

1. Internal adhesive layer is required.

2. There is a reinforcing layer, which is composed of natural or synthetic materials supplemented by appropriate methods, and it is mostly made by cloth clamping method and cord winding method.

3. It has an outer rubber layer.

In terms of hydraulics, the standards are as follows.

Sandblasting hose The working pressure of is 0.63Mpa. When he carries out the hydraulic test under twice the working pressure, no water shall be added, and no local bulge, expansion and other abnormal phenomena shall occur.

The pressure of its anti-static hose should be maintained for one minute, but the length change should not exceed 0.8% of the upper and lower, the outer diameter change should not exceed 10% of the upper and lower, and for each meter, the torsion should not exceed 60&ORDM. After that, the bursting pressure of sand blasting hose shall not be less than 4 times of the working pressure
