Concrete Pump S Valve S Pipe S Tube Wear Resistant DN200/DN230/DN260

Product features and advantages:

1,The inner wall adopts ultra-fine grain technology of high wear-resistant welding material for surfacing, which is super wear-resistant and not afraid of impact.
2,The shaft head is a high-quality forging, normalized treatment, with high strength, good toughness and long fatigue life.
3,Surface nitriding treatment of spline, hardness 650HV-800HV, good wear resistance and long useful life.
4,The quality is stable and reliable, the pumping volume is over 60,000 cubic meters (commercial concrete C30 ).

Maintenance method:

1,Accurate alignment and firm fixation during assembly.
2,The accumulated materials in the hopper shall be cleaned in time to prevent the accumulated materials in the hopper from causing the abrasion of the S tube and the bottom of the cutting ring.
3,After the cutting ring reaches its service life, please replace it in time, so as to avoid the early wear of the surfacing layer at the big end of S-tube due to step erosion.
4,After the operation, please clean the inside of S tube in time.
