Precision Manufacturing & Quality Control

Our API 5L ERW Pipes are made using state-of-the-art Electric Resistance Welded technology, ensuring consistent weld strength and dimensional accuracy. Each pipe undergoes stringent third-party inspections and impact testing, adhering to API 5L standards. Heat treatment processes like normalization and stress relieving enhance their durability and integrity, making them ideal for high-pressure and temperature applications.

Versatile Sizes and Tailored Solutions

Choose from a wide outer diameter range of 21.3 mm to 610 mm, lengths up to 12 meters, and thicknesses between 4 mm and 20 mm. We also offer custom sizes to meet specific project requirements. With flexible end options (plain or beveled), various grades, and tailored surface treatments, these pipes are suitable for multiple sectors including construction, water supply, and pipeline infrastructure.

Reliable Protection & Packaging

Our pipes are safely transported in bundled, waterproof packaging with plastic caps to prevent damage. External anti-corrosion coatings like 3LPE, FBE, or black paint provide long-term protection against harsh environmental factors. Standard and custom markings are available for easy tracking and compliance.

FAQs of API 5L ERW Pipes:

Q: How are API 5L ERW Pipes manufactured and what quality inspections are performed?

A: API 5L ERW Pipes are produced using the Electric Resistance Welded (ERW) process, where steel coils are longitudinally welded without the use of filler material. Each pipe is subject to strict third-party inspection and must pass impact testing as per API 5L requirements to ensure reliability and safety in demanding applications.

Q: What applications are API 5L ERW Pipes suitable for?

A: These pipes are engineered for use in oil & gas transmission, water supply systems, structural projects, and construction pipelines. With their high mechanical strength, corrosion resistance, and ability to withstand pressures up to 20 MPa, they are ideal for both underground and above-ground installations.

Q: When should I opt for custom sizes or specific grades of API 5L ERW Pipes?

A: Opt for custom sizes or specific grades like Gr. B, X42, X52, X60, X65, or X70 when your project requires unique dimensions or enhanced mechanical properties. Customization ensures the pipe fits your technical requirements and operational conditions seamlessly.

Q: Where can these pipes be used considering their temperature and pressure ratings?

A: API 5L ERW Pipes can safely be used in environments with temperatures ranging from -29C to 121C and under pressures up to 20 MPa. This makes them perfect for high-demand applications in pipeline infrastructure, construction, and industrial water or gas transportation.

Q: What packaging and marking options are provided for safe transport and traceability?

A: Pipes are supplied in bundled packaging with the addition of plastic caps and waterproof wrapping to prevent damage during transit. Standard and custom markings are available, ensuring each pipe can be easily traced and identified according to client or project requirements.

Q: How does surface treatment benefit API 5L ERW Pipes?

A: Surface treatments, including options like black painting, FBE, and 3LPE coatings, significantly improve resistance to environmental corrosion. These protective layers extend the lifespan of pipes, making them ideal for use in challenging conditions, whether buried or exposed.
