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):
Class A – Light
Class B – Medium
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.
