Manufacturing Process

From raw-material granules to a marked, dispatch-ready pipe — this is how production runs on our lines.

Production stages

  1. 1

    Raw material selection

    Approving suitable raw materials for each product family per the agreed standard.

  2. 2

    Material preparation

    Mixing and preparing the material and required additives before feeding the line.

  3. 3

    Extrusion

    Melting the material and forcing it through the forming die to create the pipe body.

  4. 4

    Pipe sizing

    Calibrating outside diameter and wall thickness in the vacuum sizing unit.

  5. 5

    Cooling

    Gradually cooling the pipe in water baths to lock in dimensional stability.

  6. 6

    Printing and identification

    Printing product and production-line data on the pipe for traceability.

  7. 7

    Dimensional inspection

    Measuring diameter, thickness and length and verifying conformity during the run.

  8. 8

    Quality testing

    Performing the tests specified for the product per the standard and approved agreement.

  9. 9

    Packaging

    Preparing bundles or coils with identification labels according to the product type.

  10. 10

    Dispatch

    Loading orders and delivering them under the agreed transport arrangements.

Quality checkpoints on the line

  • Material verification before feeding
  • Monitoring extrusion temperature and pressure
  • Diameter and thickness calibration
  • Haul-off speed stability checks
  • Print and identification review
  • Sample checks from every batch

A disciplined working environment

Lines operate under clear safety instructions with organised work and handling zones — protecting both people and product.
