Find a huge selection of threaded 90 degree elbow from China at SN Valve. Threaded 90 degree elbow connects with pipes or other fittings through its internal threads to achieve the turn of pipes in 90 degree direction. This kind of elbow is widely used in various industrial, construction and civil piping systems, such as petroleum, chemical, natural gas, water treatment and heating.
1.Structure: Threaded 90 degree elbow usually consists of elbow body and threaded interface at both ends. The main part of the elbow presents a 90-degree curved shape, while the threaded interface is used to connect with the threaded part of the pipe or other pipe fittings.
2.Features:
Convenient connection: the threaded connection makes the installation and disassembly of the elbow relatively simple and quick, without the need for complex welding or flange connection.
Good sealing: through the correct threaded connection and appropriate sealing materials (such as raw material tape or sealant), you can ensure a good sealing between the elbow and the pipeline.
Strong adaptability: the threaded 90 degree elbow can be used to connect pipes of different materials and specifications, with strong adaptability and high flexibility.

Materials and Manufacturing
Threaded 90 degree elbows can be manufactured using a variety of materials to meet the needs of different operating environments and media. Common materials include:
Carbon steel: with good strength and rigidity, suitable for general industrial piping systems.
Stainless steel: has excellent corrosion resistance and high temperature resistance, suitable for corrosive media or high temperature environment.
Alloy steel: with higher strength and high temperature resistance, suitable for high pressure and high temperature piping system.
During the manufacturing process, casting, forging or hot press moulding are usually used to make the elbow body, and the threaded interface is formed by machining.
