Alloy steel elbow pipe fittings are usually used to connect two lengths of pipe to redirect the fluid flow direction in many industries such as shipping, oceanographic engineering and power plants. To fulfill different requirements of direction change, our company provides a whole range of elbow pipe fittings, which include 45°, 90°and 180°elbows as well as elbows with any customized angle.

Common alloy steel features great tenacity, thermal conductivity and electrical conductivity. It could also be a kind of carbon steel which is alloyed with other alloying elements, such as silicon, manganese, chromium, nickel, tungsten, vanadium and titanium, to improve its mechanical properties, including abrasion resistance, corrosion resistance and low temperature resistance, etc. The properties will vary depending on the alloying element types and percentages. As one of alloy steels, low temperature steel is specifically used for production of pipe fittings applied in circumstances with temperature ranging between -20 and -253℃.

Hot forming by mandrel is the most applied process for manufacturing of alloy steel elbow. Through this exact process, our company is fully capable of making use of seamless steel pipes to produce seamless alloy steel elbow with various diameters.

We are also able to produce alloy steel elbow with large size by placing alloy steel in the elbow mould, conducting compression-molding process and then doing butt welding. As a result, we can provide elbow with diameter as 24inch (DN600) if customers need.

An extensive use of alloy steel fittings can be found in the following industries:

• Petrochemical industry: Oil refining, ethylene, coal to oil, coal to olefins and other projects.
• Natural gas industry: LNG ships, LNG terminals, and natural gas pipeline projects.
• Power station industry: In thermal power plant, the water pipeline used for supercritical units, circulating fluidized beds, power generation boilers, steam turbines, generators and other equipment.
• Marine engineering industry: Construction and maintenance projects for offshore platform engineering
• Shipbuilding industry: Ship maintenance project
• Others: papermaking, machinery manufacturing and other industries.
