Manufacturing Processes
Seamless Hot Rolling Processes:
  • Round Pipe Billet → Heating → Perforation → Three Roll Skew Rolling, Continuous Rolling or Extrusion
  • Off Pipe → Sizing (Or Reducing Diameter) → Cooling → Billet → Straightening
  • Water Pressure Test (Or Flaw Detection) → Marking → Storage
Seamless Cold Rolling (Cold drawn) Processes:
  • Round Pipe Billet → Heating → Perforation → Head → Annealing → Pickling
  • Oil (Copper) → Multi Pass Drawing (Cold Rolling) → Billet → Heat Treatment
  • Straightening → Water Pressure Test → Marking → Storage
Longitudinal Welding (Straight seam welding) Processes:
Including ERW, EFW methods.
Product Standards & Specifications
ASTM A312 - High Temperature and General Corrosive Applications
Specification for seamless, welded, and heavy cold worked austenitic stainless steel pipes. Widely used in sulfuric acid storage tanks, phosphate fertilizer industries, fluorosilicic acid reactors, phosphoric acid plants, chlorate crystallizers, pharmaceutical ventilation systems, solvent recovery filters, pulp and paper bleaching equipment, offshore platform pipelines, desalination systems, and seawater condensers for power plants.
ASTM A213 - Boiler and Heat Exchanger Tubing
Covers seamless ferritic carbon steel and austenitic alloy stainless steel tubes for boiler, superheater, and heat-exchanger applications.
ASTM A269 - General Use Stainless Tubing
Covers stainless steel tubes for common applications in seamless and welded configurations.
ASME SB677 - Extremely Corrosive Resistance
Specification covers UNS N08904 (904L), UNS N08925, UNS N08926 (alloy 926) in seamless, cold-drawn, and hot finished steel pipe and tube for extremely corrosive services. Includes 6% molybdenum alloy stainless seamless pipe and tube.
ASTM A789 - Duplex Stainless Tubing
Covers seamless and welded ferritic/austenitic stainless steel tubing for general services. All tubes are furnished with heat-treated condition according to specified temperature and quench conditions.
ASTM A790 - Stress Corrosion Cracking Resistance
Standard specification for seamless and welded ferritic/austenitic stainless steel pipe with particular emphasis on resistance to stress corrosion cracking. Includes comprehensive testing requirements for quality assurance.
