CHEMICAL COMPOSITE HOSE
STANDARD AND SPECIAL CHEMICAL COMPOSITE HOSES IN CHEMICAL SERVICE
We know that different media are handled by different kinds of composite hoses. So chemical fluids should be transferred by chemical composite hose, which is soft and lightweight. Chemical composite hose is composed of polypropylene films and fabrics, so they are highly resistant to most acids, alkalis and organic solvents. It can bend freely, making it easier to operate. It is mainly used to transfer various acids, alkalis and other chemical fluids which may be corrosive to the hose.
Characteristic:
- Soft and lightweight, can bend freely.
- Resistant to corrosion, oils, acids and alkalis.
- Resistant and high temperature.
- Excellent pressure resistance.
- Construction:
- Its construction is very complex for five layers: inner and outer helix, liner, carcass and cover. And also there are four types namely PG (Polypropylene coated steel inner helix and high tensile galvanized carbon steel outer helix), PS (Polypropylene coated steel inner helix and 316L stainless steel outer helix), SG (316L stainless steel inner helix, and high tensile galvanized carbon steel outer helix) and SS (316L stainless steel inner helix and 316L stainless steel outer helix).
Liner: multiple layers of PTFE films.
Carcass: multiple layers of polypropylene fabrics, films and polyester barrier layers.
Cover: abrasion resistant PVC coated fabric.
The details of chemical composite hose:
- Temperature range: -30°C to +100°C.
- Inner diameter: 25mm, 38mm, 50mm, 65mm, 75mm and 100mm.
- Outside diameter: 38mm, 52mm, 64mm, 80mm, 92mm and 120mm.
- Bend radius: 90mm, 125mm, 160mm, 180mm, 220mm and 350mm.
- Working pressure: 10 bar.
- Length: 15m.
- Couplings: externally swaged: NPT threaded; cam and groove, fixed, floating, reducing flange, etc.

Application of chemical composite hose:
- Chemical composite hose is mainly used to transfer chemical fluids, such as acids, alkalis and organic solvents.
- It is used for in-plant chemical liquids transfer operations, tank truck delivery and rail car loading.
- It is designed to transfer highly aggressive media.
- Hose wire is connected to the fittings securely, making electrical continuity maintained.
