What Are Super Duplex Steel Fittings?

Super Duplex Steel Fittings are components used in piping systems constructed with super duplex stainless steel alloy, offering outstanding corrosion resistance and mechanical strength, making it suitable for applications including oil and gas exploration and production, chemical processing, marine engineering and the like. SDSF fittings come in the form of elbows, tees, reducers and valves designed to withstand high pressure environments as well as harsh environments.

Super Duplex Steel Fittings are highly resistant to corrosion, making them suitable for applications in hostile environments like chemical processing plants, marine vessels and offshore oil and gas industries. Their superior strength compared to standard stainless steels also make them suitable for high pressure and temperatures applications.

Super Duplex Steel Pipe Fittings

Super Duplex Steel Fittings have exceptional mechanical properties, such as high tensile strength and yield strength, allowing them to withstand extreme conditions. In particular, their corrosion resistance in chloride-containing environments greatly decreases material degradation risk as well as maintenance expenses.

Super Duplex Steel Fittings may present more difficulty when it comes to being machined than their stainless counterparts due to their greater strength and hardness, however with proper tools and techniques for machining they can often achieve accurate shapes and dimensions with precision.

Super Duplex Steel Fittings provide exceptional resistance to corrosion, including pitting, crevice corrosion and stress corrosion cracking even under highly aggressive environments. Their corrosion resistant nature makes them particularly advantageous in industrial settings where corrosion may compromise structural integrity.

Super Duplex Steel Fittings have excellent weldability when proper welding techniques are followed, creating strong and secure joints. Preheating and post-weld heat treatment may be needed to minimize distortion risk while upholding corrosion resistance in welded zones.

Super Duplex Steel Fittings have numerous applications across industries including oil and gas exploration, chemical processing, desalination plants and pulp and paper production. Common applications for Super Duplex fittings are in pipe systems, pressure vessels and heat exchangers to provide exceptional strength and corrosion resistance in critical components that need exceptional strength and corrosion protection.

Super Duplex Steel Fittings can be found in offshore platforms, power generation facilities, aerospace components and automotive parts where durability and resistance to harsh environments is of utmost importance for long-term performance and safety.

Manufacturing Process Of Super Duplex Steel Pipe Fittings

Forging

Forging

Making method of forged fittings,using forging machine bevels the pipe end or extension, reduce the outside diameter.

Rolling Wheel

Rolling Wheel

Butt weld fittings, putting the core in the pipe. Then pushing the external by roller and processing the rim.

Stamping

Stamping

Using tapered core to expand the pipe end to the required size and shape in the punching machine.

Bending

Bending

For making elbow and bend fittings. There are three commonly methods. One is stretching , another is stamping , the third is roller , there are 3-4 rollers.

Bulging

Bulging

A rubber is placed in the tube and the top with a punch compression, then the pipe is bulged forming; Another method is hydraulic bulging forming.
