API 5L X42 line pipe is one of the most widely used grades in the oil, gas, water and energy sectors, offering a reliable balance of strength, ductility and weldability. Designed under the API 5L specification, X42 is engineered to meet stringent requirements for transportation of fluids under pressure, making it ideal for pipeline networks in both onshore and offshore applications. Its performance characteristics ensure durability and longevity even under variable environmental and service conditions, positioning it as a preferred choice for long-distance transmission systems.
As a stockist and supplier with a global footprint, Metal Tubular Products maintains an extensive inventory of API 5L X42 pipes in multiple forms including seamless (SMLS), ERW (Electric Resistance Welded), LSAW (Longitudinal Submerged Arc Welded), and SSAW (Spiral Submerged Arc Welded). This broad availability means reduced lead times for clients and the flexibility to serve diverse project requirements — from sprawling pipeline infrastructures to specialized industrial installations. With strategic warehousing and distribution channels worldwide, MTP ensures that clients across continents can source high-quality X42 line pipe without the delays commonly associated with international procurement.
Quality assurance is at the core of MTP’s supply process. Every shipment of API 5L X42 pipe undergoes rigorous inspection and testing in accordance with international standards, including dimensional checks, mechanical property verification and certification traceability. These quality protocols provide buyers with confidence that the material meets or exceeds the API 5L specification and is fit for demanding service conditions. Whether for hydrocarbon transmission, water supply lines, or petrochemical feed lines, the X42 grade delivers reliable performance backed by documented quality.
In addition to standard grade offerings, Metal Tubular Products offers customized solutions tailored to specific project needs. This can include cut-to-length pipes, beveling, NDT (Non-Destructive Testing) options, and coatings for corrosion protection. Such value-added services streamline installation processes and support end-users in achieving project milestones more efficiently. The company’s technical support team works closely with clients to recommend the most suitable material form, size range, and service class — be it PSL 1 or the more stringent PSL 2.

API 5L X42 pipes are primarily used for the transportation of oil, gas, water, and other fluids in pipeline systems. They are widely applied in onshore and offshore projects, refineries, petrochemical plants, and water transmission lines due to their good strength and weldability.
The designation “X42” refers to the minimum yield strength of the pipe, which is 42,000 psi (290 MPa). Higher X numbers indicate higher yield strength.
Yes, API 5L X42 pipes are available in both PSL 1 and PSL 2. PSL 2 has stricter chemical composition limits, mandatory impact testing, and enhanced quality control compared to PSL 1.
API 5L X42 pipes are manufactured in various forms such as Seamless (SMLS), ERW, LSAW, and SSAW, allowing flexibility for different pressure, diameter, and project requirements.
API 5L X42 pipes are stocked and supplied worldwide by Metal Tubular Products, offering a wide size range, quick delivery, and compliance with international quality standards for global pipeline projects.
We export steel pipes and tubes to over 60 countries worldwide, serving clients across Asia, Europe, the Middle East, Africa, Oceania, and the Americas. Our strong global logistics network ensures reliable delivery, quality assurance, and compliance with international standards.
