PolyUrea PIPES

A water board of major metropolitan city in India specified for a strong abrasion and chemical resistance coating for application inside their new RCC sewerage pipes.Theperformance of coating was to be warranted for over 25 years. The proposed material of supply had to be tested by independent third party laboratories and supplier qualification criteria were set to stringent standards.

Vibrated Casting process pipes for NP3 class and NP4 class

Following are some of the common applications of these products:

    Satyen Polymers proposed a TEVO grade of Polyurea – TEVO PP50-10. The material went through numerous tests both in the laboratory and also onsite, including extensive field testing of randomly collected samples of material applied to pipes coated at the pipe manufacturers factory.

  • The concrete inside of the pipes were surface prepared.
  • TEVO PRIME E100, an epoxy primer was applied ensuring sufficient coverage.
  • After 3 hours of Primer application TEVO PP 50-10 was spray applied on theprimer using a high-pressure plural component spray equipment.

The main features of the PolyUrea Unit

  • The manufacturing process is fully automatic. Four people monitor the functioning of the machine and moves the pipes to the drying area with a forklift.
  • The installed capacity of the machine is to produce 60 pipes for every 8-hour shift
  • The pipes moved to the curing area by forklift are wrapped in a stretchable film to retain moisture and humidity. After 24 hours of initial curing the pipes are moved to a yard and de-moulded from the pallet and allowed to be further cured.
  • This machine can produce pipes from inner diameters 300 to 2400 mm with 2500 mm length as per BIS 458/2003 standard.
  • The process involves machine production of reinforced or unreinforced pipes, round or pre-bed pipes with spigot and socket joint, with rubber joint, egg-shaped pipes, square or rectangular pipes, manholes and other items as per the customer’s requirements.
  • Normally pipes made by this process of Vibrated/Vertical Casting will have matt finish on both the inside as well as outside.
  • The concrete is mixed by automated ready-mix plant.
