Our stainless steel Flangeolets are manufactured using high-quality grades like SS 304, 304L, 316, and 316L under ASTM A182 specification. These outlet fittings are ideal for high-pressure pipelines and branch connections in refineries, chemical plants, and marine industries. We offer various configurations including socket weld, threaded, and buttweld ends. With stock-ready supply and precise machining, our fittings provide long-lasting performance and leak-proof connections even in corrosive environments.
Monel 400 and Cupro Nickel Flangeolets are known for their excellent seawater corrosion resistance, making them ideal for shipbuilding, desalination, and offshore platforms. Manufactured to precision using high-grade UNS N04400, C70600 (90/10), and C71500 (70/30), these fittings ensure excellent weldability and structural strength. Our Cupro Nickel Flangeolets are exported to markets like Kuwait, Oman, and Zambia, meeting international quality norms and customized requirements for pressure ratings and schedules.
We manufacture Duplex and Super Duplex Steel Flangeolets (UNS S31803, S32205, S32750, S32760) known for exceptional strength and resistance to chloride stress corrosion. These outlet fittings are preferred in offshore platforms, chemical processing, and power generation industries. Available in various outlet types like welding, lateral, and swept, our Duplex Flangeolets are produced as per ASTM A182 standards and pressure classes ranging from 1500# to 9000#. Our fittings offer unmatched performance in aggressive environments.
Our range includes premium Hastelloy C22, C276 and Incoloy 800/825 Flangeolets, designed for extreme chemical processing environments. These alloys provide superior resistance to oxidizing and reducing agents. Manufactured under ASTM B564/B366 specifications, our fittings are suitable for both high-pressure and high-temperature applications. Available in socketweld, threaded, and buttweld connections, our Hastelloy and Incoloy Flangeolets are widely used in Saudi Arabia, Oman, and Nigeria for critical piping systems.
