Structure:

Inner tube:

Polyurethane and butyl rubber are used as the main raw materials, and special reinforcing agent is added. It has high wear resistance and high toughness. The wear resistance index is 2-3 times that of ordinary sandblasting tubing.

Reinforcement:

The sandblast rubber hose adopts high-quality tape or cord as the reinforcing layer, which has good flexibility and strong pressure bearing capacity; the steel blasting pipe is woven with special copper wire for copper-clad hoses, and the working pressure is 3-4 times that of the cloth hoses. High pressure resistance and superior flex resistance.

Cover:

Synthetic rubber, black, oilproof, weather resistant.

Classification

The sandblast rubber hose is generally divided into a standard duty sand blasting pipe and a heavy-duty sand blast pipe according to the working condition and the loss degree of the material particles to the conveying medium, and the spiral steel wire will make it suitable for the negative pressure environment.

sistant-rubber
standard duty sand blast pipe

It is usually used in the use environment such as ship sandblasting and sand drifting operation; the common inner rubber is made of wear-resistant NBR (natural rubber) material, and the outer rubber is wrapped with composite rubber.
Heavy duty sandblasting pipe
It is used in equipment such as sandblasted gravel, pebbles and mud.


Features:

1. The working pressure of the pipes is 20-45 bar. The tubing pressure is 1min, the length change does not exceed ±0.8%, the outer diameter does not exceed ±10%, the twist per meter does not exceed 60º the burst pressure is not less than 4 times the working pressure.
2. Under the double working pressure, the hoses do not seep water, no local bulging, no expansion and other abnormal phenomena.
3. Bending performance: When the sandblast rubber hose is tested with a minimum bending radius of 10 times the nominal inner diameter at 23 ° C, the deformation KD value does not exceed 0.8 times the outer diameter D of the hose. (K is the outer diameter of the tube before bending and the ratio of the outer diameter after bending to the outer diameter before bending.)(-25 ± 2 ° C), no cracking after bending.
4. Conductivity: Each "M" grade pipe does not exceed 10 ² Ω. Each "Ω" grade tubing does not exceed 1MΩ.
