Chemical hoses are suitable for organic and inorganic liquid chemicals (acids and bases, salt solutions, paints and varnishes, solvents, etc.).
Chemical hoses are great for organic and inorganic liquid chemicals, such as acids, bases, and solvents.
First, they’re used for chemical transfer in processing, technical work in chemical, food, and pharma industries, as well as in labs. Moreover, the inner layer of the hose needs to be highly chemical – resistant.
To select the right hose for chemical resistance, it’s vital to collect data like the medium type, its state (liquid or gas), concentration, temperature, and working pressure.
Importantly, the safety data sheet of a chemical is crucial for proper hose selection. Also, check for static charge build – up risks, especially in potentially explosive zones.
Typically, the inner layer of chemical hoses is made of EPDM or EPM rubber and reinforced with textile. However, for suction delivery hoses, a steel wire helix can be added if needed. Meanwhile, the outer layer is made of rubber that resists external factors.
Furthermore, couplings and fittings for chemical hoses must be corrosion – resistant, just like their seals. We can mount the fittings using worm – drive clamps, bolt – screw clamps, or ferrules.
Finally, other hoses suitable for chemical transfer include general – purpose, food, ducting, composite, metal, PTFE, and silicone hoses.
