Concrete pumping hoses tube is made of rubber, and reinforced layer in the middle . It can bear high pressure when concrete pouring. The concrete pumping hoses can work at extreme temperature from -50°C to 100°C.
The concrete rubber hoses tube have 3 structure layers.
Handling strength of rubber | Pure rubber vulcanizate tensile strength | Tensile strength of filled 50 parts carbon black vulcanizate | Tear strength of vulcanizate filled with 50 parts of carbon black |
0.5 Mpa | 1.4-3.0 Mpa | 17-28 Mpa | 40-60 KN/M |
SBR rubber have wear resistance, heat resistance, oil resistance and chemical resistance.
The middle enhancement layer of concrete pump wire hose can be 2 layers, 4 layers. Steel wire hose has good comprehensive performance, and the steel rubber hose used for concrete convey, engineering construction.
Fabric reinforcement concrete pump hose have 2 layers, 4 layers, 6 layers, 8 layers as middle enhancement. It have 55Bar and 85Bar high pressure hoses. The more fabric layers, the more pressure the concrete pumping hose can withstand.
Length | Size | Layers | Connection |
3m, 4m, 5m, 6m, 7m, 8m, 9m, 10m etc. | 2'', 2.5'', 3'', 3.5'', 4'', 4.5'', 5'', 6'' etc. | 2 layers, 4 layers. | SK, HD, ZX, MF. |
The tail ferrule is #20 steel with galvanized. It can be suit for SK end, and also offered HD end.

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