Jindal Star MS Black Pipe Dealers In Okhla Industrial Area (Phase I, II, III)

Brand & Manufacturer

Jindal Star is one of India’s leading manufacturers of ERW (Electric Resistance Welded) Mild Steel (MS) Black Pipes, trusted across plumbing, structural, industrial, and fire-fighting applications.

Material & Manufacturing

• Material: Mild Steel (Carbon Steel)

• Manufacturing Process: ERW (Electric Resistance Welding) — ensures uniform welds and consistent quality.

• Surface Finish: Black (Bare/ Self-colour) — uncoated surface with typical mill oil or varnish finish to protect against handling corrosion.
  

Applicable Standards

• IS: 1239 (Part-1) 2004 — for MS Black Pipes and Tubes.

• IS: 3589 — for larger diameter and water/sewage transportation pipes.

• Also manufactured and compliant to BS, API, ASTM, DIN standards on request.
  

Size & Dimensions

• General Nominal Bore Range:
  15 mm (½″) to 500 mm (20″) — widely available.
  

• Wall Thickness:
  Varies by Class/type — from ~2.0 mm up to ~12.7 mm depending on nominal size and class.
  

• Typical Length:
  Random lengths — usually 4 to 7 m / 6 m / up to 12 m depending on customer order.
  

Classes / Types

Jindal Star MS Black Pipes are generally supplied in three strength classes (based on application and wall thickness):

1. Class A – Light

2. Class B – Medium

3. Class C – Heavy
   These classes define increasing wall thickness and load-bearing capability.
   

End Preparations

• Plain Ends (PE) – standard

• Beveled Ends (BE) – for welding applications

• Threaded Ends – (on demand for smaller sizes)

• Socket Ends – with protective caps (option)
  

Mechanical & Quality

• Manufactured from low carbon mild steel that is easy to weld, bend, and fabricate.

• Pipes undergo hydrostatic testing and dimensional inspections to ensure quality and performance.
  

Typical Applications

Where MS Black Pipes are commonly used:
✔ Water supply and distribution
✔ Plumbing and irrigation systems
✔ Fire-fighting mains
✔ Structural and fabrication work
✔ Scaffolding and supports
✔ Industrial process lines (non-corrosive media)
✔ Water and sewage transmission lines

Key Features

🔹 Strong mechanical strength with uniform wall thickness
🔹 Wide availability in sizes & classes
🔹 Easy to cut, weld, and install
🔹 Cost-effective solution for general piping & structural use
🔹 Compatible with standard fittings and flanges

Notes on Corrosion

• MS Black pipes are not zinc-coated — surface must be painted, varnished, or otherwise protected in corrosive environments to extend life.
  

• For outdoor/underground or wet conditions, MS GI (galvanized) pipes are preferred.
  

Summary

Jindal Star MS Black Pipes are ERW mild steel pipes manufactured to BIS and international standards with a broad size range and multiple strength classes. They are ideal for plumbing, structural, industrial and utility pipelines where corrosion is controlled through coatings or environmental protection.
