Carbon Steel Plates for Pipelines & Flanges – Reliable Material for High Pressure & Flow Systems

Looking for carbon steel plates suitable for pipeline fabrication and flange manufacturing?
At Hindustan Steel Corporation, we supply pipeline-grade steel plates and flange raw material plates with MTC, cut-to-size service, and third-party inspection support for projects in India, UAE, Saudi Arabia, Africa, and other export markets.

What Are Pipeline & Flange Steel Plates?

These are carbon-manganese steel plates used for pipe fabrication, line pipe fittings, flange rings, and pipeline support structures.

Key requirements include:

  • Good weldability
  • Moderate to high tensile strength
  • Machinability for flange facing and boring
  • Thickness consistency for large OD flanges and pipe shells

 

Applications Across Industries

  • Oil & Gas Pipelines – Transmission lines, gathering lines
  • Petrochemical Plants – Process pipe sections, fittings
  • Water Supply Projects – Large diameter pipelines
  • Power Plants – Steam piping, cooling water lines
  • Industrial Infrastructure – Pipe racks, structural pipe supports
  • Flange Manufacturing – Weld neck flanges, slip-on flanges, blind flangess
  • Pipeline Fittings OEMs – Elbows, reducers, tees

We supply both standard plates and custom cut blocks for forging shops and pipe fabricators.

Mechanical Properties & Grade Performance

Grade Yield Strength Tensile Strength Typical Use
IS 2062 Gr B/C 250–275 MPa 410–580 MPa Flange rings, supports
ASTM A516 Gr 60/70 220–260 MPa 415–620 MPa Pipe shells, large OD flanges
ASTM A36 Min 250 MPa 400–550 MPa General flange rings
EN S275 / S355 275–355 MPa 410–630 MPa High-strength line pipe supports

Impact tested (J0/J2) and UT-tested plates available for critical projects.

Technical Standards & Equivalent Grades for Pipeline & Flange Steel

Standard Common Grades Supplied
IS IS 2062 B/C
ASTM A36, A516 Gr 60/70

We supply large OD ring blanks, pipe support base plates, and forging stock plates.

Heat Treatment & Toughness

  1. Normalized condition (N) available for A516 Gr 70N and EN S355J2
  2. Stress-relieved plates for welded pipelines
  3. UT-tested plates (Level II / III) for critical pipe components and flanges
  4. Impact-tested plates for low-temperature pipeline applications

Machining, Welding & Fabrication Advice

Welding:
Plates are suitable for pipe-to-pipe welding, flange-to-pipe welding, and support bracket welding.

Cutting:
CNC plasma, oxy-fuel, or waterjet cutting for round blanks, rings, and gusset plates.

Machining:
Plates used for CNC turning, boring, facing, and drilling during flange manufacturing.

Drilling:
We offer pre-drilled plates and flanges for easier assembly.
