Concrete pump rubber end hose show:

Concrete pump end hose advantage:

1.High-pressure pipe heads are upgraded into seamlessly intergrated 37Mn5 manganese  alloy pipes,conducted quenching treatment make flange much more wear-resisting.

2.The internal rubber is made of quality natural rubber ,new -type accelerants and green anti-aging agents by consulting the technicak parameters of the rubber of airplane tires.The abrasion of the internal glue enhanced from 0.111 cubic amount of rubber hose to more than about 30 thousand cubic meters.

3.The medium rubbers adopts the lastest environmental-friendly adhensive in the world to reduce pollution and improve the adhensive force between the framework and rubber,which makes rubber hose more durable.

4.Conduct a tensile test on steel wire for each batch of rubber hose and conduct proffessional adjustments.The number of steel wire increases to 400  from 200.Their diameter reduces from 1.8mm to 1.2mm.Therefore,the pliability of rubber hose is improved greatly.Experiments show that the pressure -resistant and explosion-proof performance of the rubber hose has been improved greatly.

5.A new-type anti-aging agent is added to the external rubber to make the rubber hose have better performance in resisting blows,stretching ,ageing and ultraviolet rays.

Concrete pump end hose has won national patent:

2.Concrete pump hose flange type:(Galvanized and sulfur black)

Hose can fit SK,HD,ZX,MF end flange.(Quenching and galvanized)

1.SK148mm flange is commonly used. HD 157mm flange is special for Sany concrete pump.

2.ZX 175mm flange usually used for Putzmeister concrete pump.

3.MF 166mm flange usually used for Schwing concrete pump.
