Butt Weld Pipe Fittings, Pipe Flange, Steel Pipe
    1. Butt Weld Pipe ElbowWe have six pipe elbow production lines including four carbon steel lines and two stainless steel lines, which greatly facilitate the large-scale production according to materials and specifications.
      Four double-end elbow beveling machines greatly enhance the productivity and machining precision, in the meanwhile, much processing cost is saved.
    1. Butt Weld Pipe BendPipe bend is a common fitting used to change the direction of the pipeline. There are two major groups of 3D and 5D types based on different radiuses. In terms of materials, products are divided into carbon steel, stainless steel and alloy steel.
    1. Butt Weld Steel Pipe TeePipe tee is applied to connect three pipes in a pipeline system. The product is made by extruding seamless steel pipe using one-step forming method. Pipe tee normally falls into two classes, straight tee and reducing tee. In addition, three different materials are available that are carbon steel, stainless steel and alloy steel.
    1. Butt Weld Steel Pipe ReducerPipe reducer offers connection for two pipes with different diameters, which makes it an indispensable component in pipeline system. We provide two types of pipe reducer, concentric reducer and eccentric reducer. In terms of different materials, we also have carbon steel reducer, stainless reducer and alloy steel reducer.
    1. Butt Weld Pipe End CapPipe cap is a necessary accessory in pipeline system to cover the end of the pipe. We provide carbon steel cap, stainless cap and alloy steel cap. We have two pipe cap press machines with different working pressure, one is 100 tons and the other is 500 tons. They can produce pipe caps ranging from 1/2" to 64".

Butt Weld Pipe Fittings

Butt weld pipe fittings are steel components being used to connect various kinds of pipelines by butt welding. The product has found comprehensive applications including pipeline transportation for petro, water, steam, natural gas and others, as well as chemical industry, electrical engineering, shipbuilding, boiler, pressure vessel and offshore drilling platform, etc.

Products are made by various cold or hot working processes such as bending, extruding, pushing, mould pressing and mechanical processing.

We would be glad to construct products using different materials tailored to your special requirements. In addition, we ensure that our products are manufactured to meet the standards of ANSI, DIN, JIS, KS and EN.
