MANUFACTURING PROCESS

Products: Black Iron Pipes and Hot-Dipped Galvanized Iron Pipes
We produce pipes that conform to the following standards:


Manufacturing Process:

Electric Resistance Welded (ERW)

  • Length : Standard length is 6 meters.
  • Cut-to-length is available upon request
  • Tolerance of the Outside Diameter: 0.1-0.3mm

Hot Dipped Galvanizing:

Air Wiping and Steam Blowing System
The process will always guarantee a smooth surface
finish both inside and outside the pipe.

  • Zinc-coating Thickness: Ave. 76-85 microns
  • Hydro Testing: Based on Standards 700-2300 psi (depending on pipe size)

Other Services:

  • Special Made to Order Sizes
  • Inside Bead Removal
  • Bevelling Services

Test & Inspection

SUPREME values the quality of its product. From the time the coils (raw materials) are prepared for production. to the time it comes out of the production line, the goods are inspected strictly.

SUPREME performs the following test to ensure consistency of product quality:

  1. HYDROTEST
  2. DESTRUCTIVE TEST

    such as Tensile Strength, elongation, hardness, bending, flattening.

    These tests are conducted by accredited testing centerslike the MIRDC and U.P. Testing Laboratory.

  3. NON DESTRUCTIVE TEST

    During the line process, the dimensions and physical properties are checked for proper diameter, wall thickness, length, and straightness and workmanship.

    Zinc coating is also tested by an electromagnetic meter.
