LSAW Pipes Manufacturer in India

Types of LSAW Pipes

LSAW pipes can be classified by their forming method, applicable standard, and coating. Each type is selected according to factors such as pipe size, wall thickness, application, operating conditions, and corrosion protection requirements.

The choice of LSAW pipe type depends on the required diameter, wall thickness, material grade, manufacturing standard, operating conditions, and coating requirements. We can supply LSAW pipes according to project-specific specifications and applicable standards.

Common Materials

LSAW pipes are available in different materials to suit pipeline, piling, pressure, structural, and infrastructure applications. The material and grade are selected based on factors such as operating conditions, pressure, temperature, mechanical requirements, and the applicable standard.

Material availability depends on the required grade, pipe size, wall thickness, manufacturing standard, and project specification. Mill test certificates and applicable inspection documentation can be provided with the order.

LSAW Pipes Specification

Our LSAW pipes come in a wide range of diameters, walls, grades, and coatings. As an LSAW pipes manufacturer, we build to your standard, project specification, and delivery condition, and we bevel, coat, and pack each order to your needs.

LSAW Pipe Standards and Specifications

Every LSAW pipe follows a standard that sets its grade, size limits, testing, and delivery condition. We make LSAW pipes to the codes below and add third-party inspection on request.

LSAW Pipes Material and Grades

Each grade below comes with a mill test certificate that lists its chemistry, strength, and standard. If your project needs a grade that is not on this list, we can supply it against a custom specification.

What Is the Difference Between LSAW Pipes and Other Welded Pipes?

The main difference is the plate, the seam, and the wall. LSAW pipes come from thick plate, have one straight seam, and are commonly used for large diameter and heavy-wall applications. SSAW pipes come from coil, have a spiral seam, and are commonly used for water mains and piling. ERW pipes come from coil too, have one straight seam made without filler metal, and suit small to medium sizes.

Choose the pipe type according to the required diameter, wall thickness, pressure, material grade, applicable standard, and project specification.

LSAW Pipes Chemical Composition

Chemistry sets the strength, toughness, and weldability of a grade. Values are weight percent, maximum unless a range shows.

API 5L LSAW Pipes, PSL1 (Welded)

API 5L LSAW Pipes, PSL2 (Welded)

ASTM A252 LSAW Pipes

ASTM A671 and A672 pipes take their chemistry from the plate standard, ASTM A515 or A516, in Gr. 60, 65, or 70. The mill test certificate lists the exact values for each heat.

LSAW Pipes Mechanical Properties

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

LSAW Pipe Size and Weight Chart

LSAW pipes use outside diameter and wall thickness in mm, not schedule numbers. The chart shows weight in kg per metre for common combinations.

Available Sizes, Dimensions and Schedules

We supply LSAW pipes from 16" to 48" OD, in walls from 6 mm to 40 mm. Large pipes are ordered by OD and wall thickness in mm, not by schedule number. Standard lengths run from 6 m to 12.2 m, and we cut custom lengths for your project.

As an LSAW pipes supplier in India, we hold stock of popular sizes and grades, subject to availability, and we can supply thicker walls and larger diameters on request.

LSAW Pipe Suppliers

As experienced LSAW pipe suppliers, we manufacture and supply longitudinal submerged arc welded pipes for oil & gas, water transmission, piling, construction, and industrial applications. Our range includes API 5L LSAW pipes in PSL1 and PSL2, ASTM A252 piling pipes, ASTM A671 and A672 pressure pipes, ASTM A139 pipes, and IS 3589 pipes.

We also supply coated LSAW pipes with 3LPE, 3LPP, FBE, and epoxy coatings for different service environments. For demanding applications, our sour service LSAW pipes can be supplied with HIC and SSC testing as required.

We understand that every project has specific requirements for pipe grade, dimensions, coating, testing, and documentation. Our pipes are supplied with the required markings, coating records, inspection documents, and test reports to support quality and traceability. With a broad product range and project-focused approach, we serve customers looking for reliable LSAW pipe manufacturers and suppliers for various applications.

Applications

• Oil and Gas Pipelines: Carry crude oil and natural gas over long distances, on land and offshore.
• Water Transmission: Move water in trunk mains, penstocks, and irrigation lines.

Why Choose Us as Your LSAW Pipes Manufacturer in India?

Since 2005, we have manufactured and supplied pipes and tubes in India. Our quality and management systems are certified to ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018, and our PED 2014/68/EU and TÜV approvals support projects with European requirements.

As an LSAW pipes manufacturer, we source plate from approved mills and test it for chemistry and mechanical properties. We check the weld with ultrasonic and radiographic testing, and every pipe goes through a hydrostatic test. For PSL2 and sour service orders, we add Charpy, DWTT, HIC, and SSC tests where the project requires them. Orders ship with EN 10204 3.1 certificates, and third-party inspection is available on request.

Buyers who compare LSAW pipes suppliers usually want clear specs, reliable documents, and dependable delivery. As an LSAW pipes supplier in India, we hold stock of popular sizes, cut, bevel, coat, and pack to your order, and support export shipments with sea freight packing and documentation from our Mumbai office.
