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 ASTM A335 P22 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.

ASTM A335 P12 Pipes are used for high-temperature and high-pressure applications including boilers, superheaters, heat exchangers, refineries, and petrochemical plants. Their chromium-molybdenum alloy ensures excellent strength and oxidation resistance at elevated temperatures.
The “P12” designation indicates a chromium-molybdenum alloy steel containing approximately 0.90–1.20% chromium and 0.85–1.05% molybdenum, designed for high-temperature service with improved creep strength and corrosion resistance.
Yes, ASTM A335 P12 Pipes are supplied in seamless (SMLS) form only, as required by ASTM A335 for high-temperature alloy steel pipes.
ASTM A335 P12 Pipes are supplied in normalized and tempered condition, ensuring uniform wall thickness, dimensional accuracy, and enhanced mechanical properties.
