❓ Frequently Asked Questions
QWhat material grades are available for pipe fittings?
We offer a wide range of material grades including Carbon Steel (ASTM A234 WPB, WPC; ASTM A420 WPL9, WPL3, WPL6), Stainless Steel (ASTM A403 WP304/304L, WP316/316L, WP321, WP347), and Alloy Steel (ASTM A234 WP1, WP12, WP11, WP22, WP5, WP9, WP91), as well as Duplex & Super Duplex Stainless Steel.
QWhat is the difference between WP304 and WP304L stainless steel?
WP304L is the low-carbon version of WP304. The reduced carbon content in 304L minimizes carbide precipitation during welding, making it more suitable for heavy-gauge welded components and applications requiring superior corrosion resistance after welding.
QWhat surface treatments are available for pipe fittings?
We provide four main surface treatment options: Anti-rust Oil, Black Paint, Electric Galvanized, and Hot-dip Galvanized. Each treatment is designed to protect the fittings from corrosion and extend their service life in various environments.
QWhat is the advantage of hot-dip galvanized over electric galvanized?
Hot-dip galvanizing provides a thicker and more durable zinc coating compared to electric galvanizing, making it better suited for outdoor and harsh environments. Electric galvanizing offers a smoother, more uniform finish, which is preferred for applications requiring a cleaner appearance.
QAre Duplex and Super Duplex Stainless Steel fittings available?
Yes, we supply Duplex and Super Duplex Stainless Steel fittings conforming to ASTM A815, including UNS S31803, UNS S32750, and UNS S32760. These grades offer excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, making them ideal for demanding applications.
QWhich alloy steel grade is suitable for high-temperature service?
For high-temperature service, ASTM A234 WP91 (9Cr-1Mo-V) is widely recommended due to its excellent creep strength and oxidation resistance at elevated temperatures. Grades such as WP11, WP22, and WP5 are also commonly used in high-temperature piping systems in power and petrochemical industries.
