Structure of blasting pipe:
Inner rubber: black, smooth, antistatic, wear-resistant, SBR / NR synthetic rubber. Reinforcement layer: high-strength synthetic cord. Outer rubber: black, smooth (surface cloth), wear-resistant, antistatic, SBR / NR synthetic rubber.
Technical requirements of blasting pipe :
Bend performance When the hose 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 hose outer diameter D. (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.
