Specification:
End collar: Twin wall flange
Surface Treatment: Electrostatic Spraying
Working Pressure: 85bar-135bar
Wall Thickness: Inner 8mm, outer 3mm
Hardness: up to 62HRC
Wall material: GX350+GX20
Structure:Our twin-wall elbow is composed of GX350 inner wall and GX20 protective layer outside,Intermediate is stuffed by polymeric damping material.
Application: Used by concrete pump boom truck which have higher requirements for the end elbow which connected with rubber hose.
Life time: Common concrete 50000-80000 m³
Advantage: The super wear resistant,the protective layer with explosion-proof safety, and buffer layer can effectively absorb the impact force from both within and outside the tank.
what is the material of Concrete Pump Boom Elbow?
The Concrete Pump Boom Elbow is made of special quality steel which is quenched and carried out carburizing chemical treatment on the inner wall.
The hardness of the flanged bushings can reach 58-60 degrees and the serving life of pipeline can increase 3-5 times,which enables users to save time and cost, enhancing the production efficiency.
Material: High Manganese casted such as ST52,37Mn5,45Mn2
