Frequently Asked Questions

What are Chrome Moly pipes used for?

Chrome Moly (chromium-molybdenum) steel pipes are used in high-temperature and high-pressure environments such as power plants, refineries, and petrochemical facilities. Common grades like P11, P22, and P91 offer excellent creep strength and oxidation resistance.

Do you provide material test reports (MTRs)?

Yes, all our products come with full Mill Test Certificates (MTRs) compliant with ASTM, ASME, and API standards. We provide traceability for every heat number.

Can you supply custom sizes or alloys?

Yes, we offer custom manufacturing for non-standard sizes, special alloys (including Inconel, Hastelloy, and Monel), and fabricated components like spools and assemblies.

What is the difference between Duplex and Super Duplex?

Duplex 2205 has a two-phase microstructure (austenitic-ferritic) with good chloride stress corrosion cracking resistance. Super Duplex 2507 has higher chromium, molybdenum, and nitrogen content, offering superior strength and corrosion resistance in aggressive environments.
