ASTM D 1785

ASTM D 1785 (SCH 40 & 80)

Our permanent goal is to engage in the business of manufacturing UPVC (Rigid) pipes as per the cell classification ASTM D 1784 used in the pipe is domestically produced Unplasticized by Polyvinyl Chloride (PVC) compound.

U-PVC pipes are especially to be used for drinking water network. It meets the requirements according to ASTM D 1785 (American Society for Testing and Materials).

NFP U-PVC Pipe Characteristics

  • Friction free characteristics
  • Light Weight, Ease of Handling and Maintenance
  • Easy Installation
  • Resistance towards corrosion caused by acid, salt, oil, alkalis, moisture etc.
  • Weather Resistance
  • Chemical Resistance
  • Fire Resistance
  • Durability

NFP ASTM Standard Pipes are categorized as follows:

Category Application
Schedule 40 For Non pressure water networks
Schedule 80 For High Pressure water networks(Industrial, Above & Underground system)

NFP U-PVC Pipes Handling & Storage

  • 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.
