Selecting an industrial water hose
When selecting a water hose, it must be determined whether the use is irrigation, process water, drinking water, hot water or cleaning. Under the same fluid name there are different hygiene, pressure, temperature and me…

Safety and connections for compressed air hose
In compressed air hose, the hose and couplings are selected together; separation of the connection or rupture of the hose can cause uncontrolled movement. Working pressure, temperature, oil/moisture in the air, the lock…
-
Helix reinforcement in suction and discharge water hoses
In a suction and discharge hose, the helix is one of the structural elements that helps maintain the cross-section under suction. However, the helix material or appearance on its own is not a service approval. Vacuum, p…

Points to watch with layflat discharge hoses
Layflat hoses are products that can fold flat and take up little space when unpressurized. Selection defines the working pressure, fluid, temperature, coupling and site conditions. Using the layflat construction for dis…
-
Industrial washdown hoses and service conditions
Washdown hose selection covers the water temperature, pressure, cleaning chemicals, gun connection and external environment together. Hot water, steam and high-pressure washing are not interchangeable service names. Eac…
-
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…
-
Petroleum and fuel transfer hoses
In oil and fuel hose selection, the actual chemical composition, temperature and mode of use of the product must be determined. Diesel, gasoline, biofuel blends and hydraulic oil are not the same compatibility row. In a…
-
Selection checklist for tank truck hoses
A tanker transfer hose is selected together with the conveyed product, filling/unloading method, connection system, handling loads and facility safety requirements. As important as the hose's pressure rating are the sui…

Why an LPG hose is not a general fuel hose
An LPG hose should not be treated as equivalent to a general fuel or oil hose. The product must be explicitly designed for the relevant phase of LPG, the operating condition and the mode of use. The suitability of the h…
-
Service distinctions in welding gas hoses
Welding gas hoses are selected according to the gas to be conveyed and the equipment. Product suitability, connection and marking requirements are separate for oxygen, acetylene and other fuel gases. Color alone should …
-
The concept of permeation in gas transfer
Permeation is the ability of a fluid to pass through the hose material at the molecular level. It is not the same mechanism as a visible hole or a connection leak. For gases, volatile or hazardous fluids, it must be add…
-
Which hose is used in a fire hose cabinet?
Two types of hose are used in building fire hose cabinets. In buildings without trained staff, a cabinet to TS EN 671-1 with a round semi-rigid hose to TS EN 694, 25 mm in diameter and at most 30 m long, is required. In…

How to choose a garden watering hose?
For a garden watering hose, first choose the inside diameter and length according to the distance the water has to travel; then look for a braid-reinforced construction with a UV-resistant outer layer and an opaque inte…
