Carbon Steel ERW Pipes Manufacturer in India

Carbon Steel ERW Pipes Specification

Carbon Steel ERW Pipe Standards and Specifications

Carbon Steel ERW Pipes Material and Grades

Common Materials

Carbon steel ERW pipes are generally produced from low-carbon steel, selected for good strength, weldability, and consistent forming during the ERW process. Common specifications include ASTM A53 Grade A and B, ASTM A135 Grade A and B, ASTM A500 Grade B and C, API 5L Grade B through X70, and IS 1239 light, medium, and heavy classes.

For European requirements, grades such as EN 10217-1 P235TR2 and P265TR2 and EN 10255 S195T are also available for suitable applications. The grade is selected according to the required pressure, mechanical properties, service conditions, and applicable standard.

We are a carbon steel ERW pipes manufacturer with experience in producing different grades, sizes, wall thicknesses, lengths, and finishes. When placing an order, the grade, standard, size, and finish should be specified together to ensure the pipe matches the intended application.

What Is the Difference Between Carbon Steel ERW Pipes and Seamless Pipes?

The difference is the seam, and the seam changes price, pressure limits, and design rules. Carbon steel ERW pipes have one welded seam and cost less. Seamless pipes have none and suit the highest pressure and temperature. Design codes reflect this. Under ASME B31.3, A53 Type E welded pipe carries a quality factor of 0.85, while seamless A106 pipe carries 1.00, so the same wall can carry a little less pressure in ERW.

Choose ERW when the line carries water, air, gas, or oil at moderate pressure, or when you build structures. Choose seamless when steam, high temperature, or high pressure sets the design.

Carbon Steel ERW Pipes Chemical Composition

Low carbon keeps the pipe weldable and easy to fabricate. Values are weight percent, maximum unless a range shows.

Carbon Steel ERW Pipes Mechanical Properties

Mechanical properties show how much load the pipe carries before it stretches (yield) or breaks (tensile). Values are minimum.

Carbon Steel ERW Pipe Size and Weight Chart

Each cell reads "wall in mm / weight in kg per metre". Dimensions follow ASME B36.10M for black carbon steel pipe.

IS 1239 (Part 1) Medium and Heavy Class

To work out the weight of any size, use Weight (kg/m) = (OD − Wall) × Wall × 0.02466, with both values in mm. Galvanizing adds about 4% to 7% to the black pipe weight.

Available Sizes, Dimensions and Schedules

We roll carbon steel ERW pipes from 1/2" to 24" NPS. A schedule is a wall-thickness code, so SCH 40 gives a different wall in mm at each pipe size, while the outside diameter stays fixed for each NPS. For Indian projects, IS 1239 light, medium, and heavy classes set the wall by nominal bore instead.

Standard lengths are 6 m and 12 m, plus single random (16–22 ft) and double random (36–40 ft). We cut to any length your site needs. As a carbon steel ERW pipes supplier in India, we hold the common sizes in black and galvanized finish, subject to availability.

Carbon Steel ERW Pipes We Manufacture and Supply

Our range includes black ERW pipes, galvanized ERW pipes, ASTM A53 Type E pipes, ASTM A135 pipes, API 5L PSL1 and PSL2 ERW pipes, IS 1239 medium and heavy class pipes, and ASTM A795 sprinkler pipes. We also manufacture and supply square and rectangular hollow sections, scaffolding pipes, conduit pipes, and structural tubes.

For projects requiring additional corrosion protection, we supply 3LPE, FBE, and epoxy coated ERW pipes. Threaded and coupled, grooved, bevelled, and plain-end options are available depending on the application and applicable standard.

Our carbon steel ERW pipes supplier operations support both domestic and export requirements, with regular availability of commonly ordered specifications and the capacity to handle bulk quantities for industrial and project orders.
