Frequently Asked Questions
Q
What material grades are available for carbon steel pipe fittings?
Our carbon steel pipe fittings are available in ASTM A234 WPB and WPC grades, as well as ASTM A420 WPL9, WPL3, and WPL6 grades, suitable for a wide range of industrial and low-temperature applications.
Q
Which stainless steel grades do you supply?
We supply stainless steel fittings conforming to ASTM A403, including WP304, WP304L, WP316, WP316L, WP321, and WP347, covering standard and low-carbon variants for corrosion-resistant requirements.
Q
Do you offer Duplex and Super Duplex Stainless Steel fittings?
Yes. We provide Duplex and Super Duplex Stainless Steel fittings per ASTM A815, including UNS S31803 (Duplex 2205), UNS S32750 (Super Duplex 2507), and UNS S32760, ideal for highly corrosive and high-pressure environments.
Q
What alloy steel grades are available?
Our alloy steel fittings are manufactured per ASTM A234 and cover grades WP1, WP12, WP11, WP22, WP5, WP9, and WP91, suitable for high-temperature and high-pressure service conditions in power and petrochemical industries.
Q
What surface treatment options are available for pipe fittings?
We offer multiple surface treatment options including anti-rust oil, black paint, electric galvanized, hot-dip galvanized, 3LPE (Three-Layer Polyethylene), and 3LPP (Three-Layer Polypropylene) coatings to meet different corrosion protection and environmental requirements.
Q
What is the difference between 3LPE and 3LPP coating?
3LPE (Three-Layer Polyethylene) coating is widely used for pipelines operating at normal to moderately elevated temperatures, offering excellent moisture and corrosion resistance. 3LPP (Three-Layer Polypropylene) is preferred for higher temperature applications, providing superior mechanical strength and thermal stability compared to 3LPE.
