Triplex Sewer & Drainage Pipe

Triplex is a corrugated sewer and drainage pipe manufactured in HDPE up to diameters of 1,000mm (I.D.). Joints are easily established on site using the proven slip on fitting with gaskets. Gaskets are securely located in pipe notches and feature a service life equivalent to that of Triplex sewer and drainage pipe.


Examples of Applications

  • Sewer and household waste water
  • Storm water collection
  • Rainwater harvesting
  • Industrial waste water
  • Gravity piping

Key features

  • 50 years service life
  • Large bore polymeric alternative to traditional materials (I.D. up to 1,000mm)
  • Lengths made to order
  • Low mass for ease of handling
  • Produced in HDPE
  • High impact strength
  • Minimal to no storage –, transport– or site damage
  • Able to withstand soil movement and loads
  • Smooth bore
    • Lower fall required
    • Helps reduce sedimentation which restricts the useful service area of the pipe.
  • High abrasion resistance
  • UV Stabilised
  • High resistance to chemicals and no corrosion
  • Slip on fitting with gasket joint
    • Simple joint system and requires no special equipment
    • Suitable for confined areas — narrow trenches are less costly.
  • Internal wall surfaces are co-extruded in a light colour. The increased luminosity significantly improves the ease with which pipelines may be surveyed using camera equipment.
  • Moulded fittings available up to 400mm diameters
    • Couplers & sliding unions
    • Coupler with branch to PVC pipe
    • Branch connections
    • Tees
    • Adaptors
    • Reducers
    • Elbows (45 and 90 Deg.)
    • End caps
    • Concrete passage nipple

FKS (Firat Sewer System)

Firat, in technological partnership with Krah GmbH, developed the Firat Sewer System (FKS); a high performance structured wall pipe manufactured up to diameters of 3,600mm (I.D.), for sewer, drainage and non-pressure applications.

Krah GmbH in Germany developed the spiral pipe technology especially for the production of thermoplastic pipe in large diameters. The technology, together with integral bell and spigot EF (electro fusion) joints, has brought the proven performance of polymer pipe and electro fusion to large bore applications.

Examples of Applications

  • Sewer and drainage
  • Sea outfall
  • Manholes
  • Ventilation and aeration
  • Fabrication of tanks and storage vessels

Key features

  • 50 years service life
  • Large bore polymeric alternative to traditional materials (I.D. up to 3,600mm)
  • Available in lengths of 6m – 1m
  • Low mass for ease of handling
  • Produced in either HDPE or PP
    • (note *) HDPE or PP selected in accordance with the field of application and load conditions.
  • High impact strength
  • Minimal to no storage –, transport– or site damage
  • Able to withstand soil movement and loads, rodents and roots
  • Smooth bore
    • Lower fall required
    • Helps reduce sedimentation which restricts the useful service area of the pipe.
  • High abrasion resistance
  • UV Stabilised
  • High resistance to chemicals and no corrosion
  • Integral bell and spigot EF (electro fusion) joints
    • Quick, leak-tight, fusion weld joints
    • Enables welding within confined areas — narrow trenches are less costly.
    • Butt weld joints available on request
    • FKS pipe may also be ordered with integral adaptors for flanged joints
    • Bell and spigot gasket joint may also be used under special circumstances
  • Internal wall surfaces are co-extruded in a light colour. The increased luminosity significantly improves the ease with which pipelines may be surveyed using camera equipment.
  • Auxiliary pipe fittings available
    • Tees
    • Reducers
    • Branch connections
    • Elbows
    • Fabricated to design requirements
  • Can be manufactured (by request) with a special film coating for critical applications requiring the discharge of static electricity.
