L290M is an API 5L PSL2 pipeline steel grade with a minimum yield strength of 290 MPa. The "M" designation indicates a thermomechanically controlled delivery condition. API 5L PSL2 specifies mechanical-property requirements for both the pipe body and the weld seam.
L290M Material Performance
API 5L PSL2 L290M HFW steel pipe provides a defined strength level for crude oil gathering and other pipeline applications. Its minimum yield strength of 290 MPa and tensile strength range of 415–655 MPa support engineering assessment against the pipeline's design conditions. Final material selection should account for operating pressure, transported fluid, temperature, corrosion exposure and applicable project codes. Quality verification can include chemical composition analysis, tensile testing, hydrostatic testing, dimensional inspection and weld-seam nondestructive testing, as required by API 5L and the purchase specification. Material traceability and inspection documentation can be arranged according to project requirements.

Explore how Huayang manufactures LSAW and HFW steel pipes through established production processes, from raw material preparation and forming to welding, inspection, and final delivery.
Quality is controlled throughout the steel pipe manufacturing process at Huayang, from incoming raw material inspection to final product verification. Raw materials are sourced from established steel suppliers and undergo chemical composition analysis, mechanical property testing, and surface inspection upon arrival. During production, process controls and dimensional checks help ensure compliance with applicable standards and customer specifications. Finished pipes are subject to relevant inspections and tests, which may include hydrostatic testing, ultrasonic testing (UT), radiographic testing (RT), eddy current testing, dimensional inspection, and visual examination, depending on the product type and applicable requirements. Our testing facilities support quality verification at key production stages, while inspection records and quality documentation help provide traceability and confidence in product conformity.
- Non-Destructive Testing (NDT):
- Outside diameter, wall thickness, length, straightness, weld condition, and pipe-end inspection
- Material test certificates, inspection records, and third-party inspection reports, subject to order requirements

Pipe-end protection is advisable in case the pipe-ends are bevelled at the pipe manufacturer. In the case of overseas transport, there is an especially increased risk of damaged pipe-ends. This is caused by extra handling procedures in ports and shifting of the pipes onboard vessels.
can be applied along the pipe body. This wrapping helps to safeguard the coating surface from scratches, moisture, and contamination during long-distance transportation or prolonged outdoor storage. Especially for coated or painted pipes, the additional protective cloth layer significantly reduces the risk of mechanical damage, UV exposure, and corrosion initiation, ensuring the pipes arrive at the destination in optimal condition.
In addition to pipe-end protection and external wrapping, Huayang provides customized to meet different project specifications and environmental requirements. Available options include water-based eco-friendly quick-drying paint, epoxy paint, quick-drying black paint, bituminous paint, and high-temperature-resistant paint. Paint type and application can be selected according to customer requirements, providing suitable surface protection for transportation, storage, and service conditions.
Beyond standard steel pipe manufacturing, Huayang provides customized deep processing services to meet different project and installation requirements. Our capabilities include flange welding, loose flange assembly, steel pipe piles, extra-long pipe joining, end beveling, and other fabrication services. Processing can be carried out according to customer drawings, technical specifications, and project requirements, helping customers reduce on-site fabrication work and improve installation efficiency.
