Orientflex will deliver a container of PVC suction hose to Africa
Sandblasting hose is also called rubber hose for sandblasting. It is suitable for blasting and rusting metal surface by wind pressure, sand blasting, sandblasting and wet sandblasting and dry sandblasting in engineering construction. It is suitable for blasting and rusting metal surface by wind pressure, sand blasting, sandblasting and wet sandblasting and dry sandblasting in engineering construction. Common application fields are shipbuilding, machining, spraying, etc.
Sand blasting pipes are generally composed of the following parts: Inner lining (inner rubber layer);-Reinforced layer of natural or synthetic fabrics laid by appropriate methods; Outer cover (outer rubber layer); Among them, the reinforcement layer is mostly sandwich Tape method and cord winding method.
Sandblasting pipe quality inspection standard
- The maximum working pressure of the hose is 0.63MPa.
- 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 anti-static hose maintains pressure for 1min, the length change should not exceed ± 0.8%, the change of outer diameter should not exceed ± 10%, and the torsion should not exceed 6.
- The burst pressure of the hose should be no less than 4 times the working pressure. Bending performance When the hose is tested with a minimum bending radius of 10 times the nominal inner diameter at 23℃, 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.) When there is no cracking after bending.
