QWhat material grades are available for pipe fittings?
We supply pipe fittings in 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, WP11, WP22, WP91, etc.), as well as Duplex and Super Duplex Stainless Steel grades.
QDo you offer Duplex and Super Duplex Stainless Steel fittings?
Yes. We provide Duplex and Super Duplex Stainless Steel fittings conforming to ASTM A815, including UNS S31803, UNS S32750, and UNS S32760, suitable for highly corrosive and high-pressure environments.
QWhat surface treatment options are available?
Our pipe fittings can be supplied with a variety of surface treatments including anti-rust oil, black paint, electric galvanized, and hot-dip galvanized, depending on the application and customer requirements.
QWhat is the difference between electric galvanized and hot-dip galvanized?
Electric galvanizing applies a thin, uniform zinc coating through electroplating, offering a smoother finish and tighter dimensional tolerances. Hot-dip galvanizing immerses the fitting in molten zinc, producing a thicker, more durable coating with superior corrosion resistance for outdoor or harsh environments.
QWhich material is recommended for low-temperature service?
For low-temperature applications, Carbon Steel grades such as ASTM A420 WPL3, WPL6, and WPL9 are specifically designed to maintain toughness and impact resistance at sub-zero temperatures, making them ideal for cryogenic and cold-climate piping systems.
QCan custom material grades or surface treatments be arranged?
Yes. We can accommodate special material grade requests and customized surface treatment requirements based on project specifications. Please contact our technical team with your detailed requirements for a tailored solution.
