Concrete Pumping Hoses With Steel Wire

Concrete pumping hoses is conveying cement, and steel hoses have 3 structures. The inner rubber takes NR/NBR/SBR usually. The enhancement is made of 4 wire steel layer. External rubber is always with high wear resistance.

With the concrete pump equipment work, the rubber hose should bear high pressure.The tail ferrule is usual SK end, and can be offered HD end.

 

The standard length of end hoses is 3 meters, and the other size can be customized.

How to choose concrete pumping hoses?

If the concrete particle size is less than 25mm, the inner 125mm concrete hoses can be used;
If the concrete particle size is less than 40mm, the inner 150mm concrete hoses can be used.

 

Feature

  • High pressure resistance
  • High wear resistance
  • Durability

 

Application

The concrete pumping hoses connect with drag pump for pouring, and it also use for end of hose pumping.

Precautions

  • When using steel rubber hose, do not allow small bend radius.
  • If the inner rubber and the flange at the outlet is obviously worn, please replace it immediately to avoid danger.
  • It is forbidden to connect the pipe tube to the end hose, because the strength of the hose is not strong enough, and the hose may be broken when concrete pouring.
