Technical requirements of blasting pipe
The operating temperature of the hose is -20—45 ℃
Hydraulic requirements 1. The maximum working pressure of the hose is 0.63MPa.
2. When the hose is hydraulically tested at twice the working pressure, it should be free of water leakage, local bulging, expansion, and other abnormal phenomena. The antistatic hose maintains pressure for 1min, the length change should not exceed ± 0.8%, the outer diameter change should not exceed ± 10%, and the torsion should not exceed 60 & ordm;
3. The burst pressure of the hose should be no less than 4 times the working pressure.
The bending performance of the sand blasting tube
is tested with a minimum bending radius of 10 times the nominal inner diameter. The deformation KD value should not exceed 0.8 times the outer diameter D of the hose. (K is the ratio of the outer diameter before bending of the hose minus the outer diameter after bending to the outer diameter before bending.)
The electrical resistance of the antistatic hose should not exceed 2.0MΩ / m.
