FAQs of API 5L X70 Pipes:

Q: How are API 5L X70 pipes manufactured and what inspection methods are used?

A: API 5L X70 pipes can be manufactured using ERW (Electric Resistance Welded), LSAW (Longitudinal Submerged Arc Welded), SSAW (Spiral Submerged Arc Welded), or seamless methods. To ensure quality, every pipe undergoes 100% hydrostatic testing, and, as applicable, ultrasonic and eddy current inspections according to API 5L standards.

Q: What are the available end types and connections for these pipes?

A: Pipe ends are available as square cut, grooved, or beveled. Connection types offered include butt weld, threaded, and plain ends, and threads can be API, NPT, or BSPT (upon request) to suit diverse installation needs.

Q: When should impact testing be performed on API 5L X70 pipes?

A: Impact testing is necessary when the pipes are intended for low-temperature service, as required by the relevant specification. This ensures the material retains its toughness and reliability under cold operating conditions.

Q: Where can these pipes be used and what is their typical application?

A: API 5L X70 pipes are primarily used in the oil, gas, and water supply sectors, as well as in structural applications for the petroleum and natural gas industries. They are suitable for fluid transmission and can handle rated pressures up to 35 MPa.

Q: What benefits do different coating options provide for API 5L X70 pipes?

A: Coating options such as FBE, 3LPE, 3LPP, epoxy, and black paint protect the pipes against corrosion and environmental damage, enhancing longevity and reducing maintenance in harsh service conditions.

Q: How are the pipes packaged and protected during delivery?

A: Each pipe is supplied with plastic caps at both ends, bundled with steel strips, and wrapped with a plastic sheet for additional protection. Packaging can also be customized as per customer requirements to ensure safe transportation and delivery.

Q: What documentation is provided with the delivery of API 5L X70 pipes?

A: Test certificates are provided in accordance with API 5L standards, and each pipe is marked with the heat number, size, and grade for full traceability and compliance.
