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.
Designed for suction and discharge of the most aggressive chemicals and searching solvents and is generally used where the chemical resistance of polypropylene is inadequate.
Construction
Chemical composite hose construction is very complex and is done in five layers : inner and outer helix, liner, carcass and cover.
| Inner Wire | : | SS 304 / SS 316 |
| Lining | : | Multiple layers of PTFE films |
| Carcass | : | Plies of Polypropylene films and fabrics |
| Cover | : | Weather resistant and anti-abrasive PVC |
| Outer Wire | : | Galvanised Steel / SS 304 / SS 316 |
| Temp. Range | : | -30°C to +80°C |
| Working pressure | : | 10 bar |
Characteristic
- Soft and lightweight, can bend freely.
- Resistant to corrosion, oils, acids and alkalis.
- Resistant and high temperature.
- Excellent pressure resistance.
Application
Chemical composite hoses are excellent for applications involving:
- Transfer of 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.
