Q
Do 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, ideal for high-corrosion and high-pressure environments such as offshore and chemical processing.
Q
What alloy steel grades are available?
Our alloy steel fittings are manufactured per ASTM A234 in grades WP1, WP12, WP11, WP22, WP5, WP9, and WP91, designed for high-temperature and high-pressure service in power generation 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, and 3LPE/3LPP coating, ensuring long-term corrosion protection for various service environments.
Q
Which surface treatment is recommended for buried or subsea pipelines?
For buried or subsea pipeline applications, 3LPE (Three-Layer Polyethylene) or 3LPP (Three-Layer Polypropylene) coatings are highly recommended due to their superior anti-corrosion performance, mechanical protection, and long service life.
