ASTM A335 P11 is a low alloy, heat-resistant seamless steel pipe designed for high-temperature service in boiler applications. This grade contains 1.00 to 1.50% chromium and 0.44 to 0.65% molybdenum, offering improved corrosion resistance and strength at elevated temperatures. The supplier provides sizes from 1/2" to 48" outer diameter, with wall thicknesses covering Schedules 10 through 160, as well as STD, XS and XXS. Non-standard dimensions and custom wall thicknesses are available on request, with manufacturing options for hot-finished or cold-drawn processes.
The pipe is suitable for surface heating in low and medium-pressure boilers with working pressures up to 5.88 MPa and temperatures up to 450°C, as well as high-pressure boilers with working pressures of 9.8 MPa or higher and temperatures between 450°C and 650°C. P11 is a ferritic alloy steel, standard for applications where resistance to hydrogen attack and thermal shock is required. Typical industry use includes superheaters, reheaters, and steam pipelines in power plants and refineries.
Primary buyers include boiler manufacturers, power generation plants, and oil and gas facilities sourcing durable piping for high-temperature, high-pressure environments. The material is often selected for its balance of cost and performance in moderate temperature service. Buyers should confirm pressure ratings, temperature limits, and dimensional tolerances for their specific application. Packaging is typically in bundles with end caps, and lead times depend on size and quantity.

Before ordering ASTM A335 P11 seamless steel pipes from Xi'an Overseas Oilfield Services Co., Ltd., verify the exact chemical composition and mechanical properties to ensure compliance with your project specifications. Request mill test certificates (MTCs) to confirm the material meets ASTM A335 standards, including chromium and molybdenum content. Check that the pipe dimensions and tolerances align with your system requirements, especially for non-standard sizes.
Confirm logistics details such as packaging, which is typically in bundles with end caps to prevent damage during transit. Discuss lead times, as custom sizes or cold-drawn processes may extend delivery. Clarify Incoterms, with FOB Xi'an being a common choice for this supplier, and agree on payment terms that protect both parties. Buyers should also inquire about the supplier’s ability to handle large or urgent orders.
Quality checks should include visual inspection for surface defects, dimensional verification, and non-destructive testing (NDT) such as ultrasonic or eddy current testing for seamless pipes. Request third-party inspection certificates if required by your industry standards. Ensure all documentation, including MTCs and inspection reports, is provided before shipment. For high-pressure applications, confirm that the material has undergone heat treatment to relieve residual stresses.
