Abrasion resistant sand blasting rubber pipe is a kind of material conveying pipe. Common black, yellowish or transparent; The outer rubber packing belt is mostly used for wrapping, and the steel wire is usually used between the inner and outer rubber to apply to the negative pressure working condition.

below Sandblasting pipe The factory editor will give you a detailed introduction to the relevant knowledge of sandblasting wear-resistant rubber pipe.

1. Product performance of abrasive rubber pipe:

As Sandblasting hose Its main performance is also the main judgment basis for users to distinguish the quality of rubber hose. According to the current industry standard HG/T2192-2008, according to method A of ISO 4649, the wear volume shall not exceed 140mm ³。 (The test method used in the previous old industry standard is: Akron abrasion method --- the abrasion volume does not exceed 0.8cm ³/ 1.61km。 Although this method has been replaced by method A of ISO 4649 since 2008, some domestic hose users still use this method.)  

2. Material and structure: sand blasting pipe shall be composed of the following parts:

Inner lining (inner rubber layer);

Reinforcing layer of natural or synthetic fabric laid by appropriate method;

Outer coating (outer glue layer);

Among them, the reinforcement layer mostly adopts the adhesive cloth method and cord winding method.

3. Hydraulic requirements for abrasive rubber pipe:

① The working pressure of the hose is 0.63MPa.

② The hose shall be free from water seepage, local bulge, expansion and other abnormalities when conducting hydraulic test under twice the working pressure. Keep the pressure of anti-static hose for 1min, and the length change shall not exceed ± 0.8%, the outer diameter change shall not exceed ± 10%, and the torsion per meter shall not exceed 60 º.

③ The bursting pressure of the hose shall not be less than 4 times of the working pressure.

Bending performance: at 23 ℃, when the hose is tested with the minimum bending radius of 10 times the nominal inner diameter, the deformation KD value shall not exceed 0.8 times the outer diameter D of the hose. (K is the ratio of the outer diameter before bending minus the outer diameter after bending to the outer diameter before bending.) (- 25 ± 2 ℃), there should be no cracks after bending.

Conductivity: each "M" grade hose shall not exceed 10 ² Ω。 Each "Ω" rubber hose shall not exceed 1M Ω.

4. Service temperature: the service temperature of the hose is - 20-70 ℃.
