Frequently Asked Questions
QWhat material grades are available for carbon steel pipe fittings?
Carbon steel pipe fittings are available in ASTM A234 WPB and WPC grades, as well as ASTM A420 WPL9, WPL3, and WPL6 grades, covering a wide range of temperature and pressure applications.
QWhich stainless steel grades are offered?
Stainless steel pipe fittings are available in ASTM A403 grades including WP304, WP304L, WP316, WP316L, WP321, and WP347, suitable for corrosive and high-temperature environments.
QWhat is the difference between Duplex and Super Duplex Stainless Steel?
Duplex stainless steel (e.g., UNS S31803) offers a balanced microstructure of austenite and ferrite, providing good corrosion resistance and strength. Super Duplex (e.g., UNS S32750, UNS S32760) offers even higher resistance to pitting and crevice corrosion, ideal for more aggressive environments.
QWhat surface treatment options are available for pipe fittings?
Available surface treatments include anti-rust oil, black paint, electric galvanized, and hot-dip galvanized. Each option provides different levels of corrosion protection suitable for various storage, transport, and installation conditions.
QWhat is the advantage of hot-dip galvanized surface treatment over electric galvanized?
Hot-dip galvanizing provides a thicker and more durable zinc coating compared to electric galvanizing, offering superior corrosion resistance especially in outdoor or harsh industrial environments. Electric galvanizing produces a thinner, smoother finish more suitable for aesthetic or mild-environment applications.
QCan alloy steel fittings be used in high-temperature and high-pressure applications?
Yes. Alloy steel grades such as ASTM A234 WP11, WP22, WP5, WP9, and WP91 are specifically designed for high-temperature and high-pressure service, making them ideal for power generation, petrochemical, and refinery piping systems.
