BS 3505 and 3506
NFP is predominantly engaged in the business of manufacturing UPVC (Rigid) pipes. The material used in the manufacturing of the pipe is domestically produced (Rigid) by Polyvinyl Chloride (PVC) Compound.
U-PVC pipes are especially to be used for cold potable water networks. It meets the requirements according to British Standard (BS) 3505 & 3506.
NFPU-PVC Pipe Properties
- Friction free characteristics
- Light Weight, Ease of Handling and Maintenance
- Easy Installation
- Resistance towards corrosion caused by acid, salt, oil, alkalis, moisture etc.
- Chemical Resistance
- Weather Resistance
- Fire Resistance
NFP British Standard (BS) pipes are categorized as follows:
|Class C||For Non pressure water networks|
|Class D||For Non pressure water networks|
|Class E||For High Pressure water networks (Industrial, Above & Underground system)|
|Class 6||For High Pressure water networks (Industrial, Above & Underground system)|
|Class 7||For High Pressure water networks (Industrial, Above & Underground system)/td>|
- When off-loading, pipes should be lowered, not dropped to the ground, care being taken to ensure that pipes do not fall one upon another and care must be taken to avoid contact with any sharp edges, nor on to any hard or uneven surfaces.
- UPVC pipes prefer to be stored to avoid ultra violet (UV) degradation from the sun light.
- Pipes should not be stacked in large piles, might result in deformation & difficult jointing later.
- For temporary storage in the field, where racks are not provided, the ground should be level and free from loose stones. Pipes stored should not exceed three layers high and stacked to prevent movement.
- For long-term storage, pipe racks should be provided for size below 6 inch where stored not more than 7 layers or 6ft., (1.8mtrs) whichever is the lesser.
- The standard length is 6 meters or as required.
- Standard Color: Grey, White or as required.
- Pipes with plain end or solvent cement socket end.
- Class 7 pipes are suitable for screw threading for pressures not exceeding Class C rating.
- Classes 6 and 7 are equivalent to American Schedules 40 and 80 respectively.
