hose flange using 37Mn5 material pipe,overall design,inner surface quenching,more wear-resisting.

Inner rubber in reference to the parameters of aircraft tire,abrasion is 0.150 cubic centimeters,make the hose converying concrete amount to 20000CBM.

After adjust the rubber hose steel wire ,wire diameter from 2.1mm to 1.8mm,from original article of the 180 article,experments show that hose pressure explosion-proof performance is greatly enhanced.

Outer rubber to join the new stabilizer,make hose more resistance to blow,tensile anti-aging,improve the performance of rubber outside the protection of steel wire.
