Selecting hoses for abrasive materials
In an abrasive material hose, the inner tube, particle type, grain size, conveying velocity and routing are assessed together. A thick inner tube on its own is not a guarantee of long life. Bends, flow restrictions and …

Line and end connection compatibility in concrete hose
In concrete hose, the hose body, end connection and coupling system must be verified together. The same diameter or a similar coupling profile does not show that different parts will work together safely under pressure.…

Cement and powder transfer hoses
For cement and powder transfer hose, the dry/wet state of the material, conveying method, temperature, pressure/vacuum and electrical requirements must be defined. Dry powder transfer and concrete pumping are not the sa…

Abrasion and electrical properties in sandblast hose
In sandblast hose, abrasion resistance and electrical behavior are assessed together. The abrasive type, grain size, operating condition, nozzle and connection system must be determined. The term 'antistatic' alone does…

Key parameters for slurry and dredging hoses
Slurry and dredging hose selection covers the properties of the solids in the liquid, density, flow rate, suction/discharge condition and mechanical movement together. The liquid being water alone does not show that a s…
