Butt welding pipe fittings are made from seamless pipes, welded pipes or steel plates. This type of pipe fittings covers a wide range of sizes and can be adapted to various design requirements of pipeline systems.Butt welding pipe fittings can be made from various materials such as carbon steel, low-temperature steel, pipeline steel, alloy steel, stainless steel, duplex stainless steel, etc.,which can be adapted to pipeline systems in different environments.Therefore, it is widely used in chemical, food, petroleum, natural gas, biopharmaceutical and other industries.
Common types of butt welding pipe fittings include 90 degree elbow, 45 degree elbow, tee, crosse, cap, concentric reducer, eccentric reducer, stub end, etc. The ASME B16.9 standard defines the size ranges for various types of butt welding pipe fittings.
90°Elbow Dimensions
Butt welding elbow is the most commonly used to pipeline system. It is a pipe fitting that changes direction in the pipeline system.
