  ANSI B16.9 ASTM A234 WPB Carbon Steel Pipe Fitting Reducing Tee is mainly used as a branch pipe of the main pipeline to change the direction of the fluid. It is also called a pipeline tee or tee fitting. So, how are tees produced, and what are the processing methods for ANSI B16.9 ASTM A234 WPB Carbon Steel Pipe Fitting Reducing Tee?

  The processing methods of ANSI B16.9 ASTM A234 WPB Carbon Steel Pipe Fitting Reducing Tees mainly include the following:

  1. Forging

  That is, a forging machine (rotary type, connecting rod type, roller type) is used to punch the end or part of the pipe to reduce the outer diameter.

  2. Stamping

  Use a tapered core to expand the pipe end to the required size and shape. This operation is performed on a punch machine.

  3. Roller

  For round edge processing, a core is placed inside the tube and the outer periphery is pushed with a roller.

  4. Rolling

  It is suitable for the inner round edge of thick-walled pipes, and generally does not require a mandrel.

  5. Bulging

  There are two main methods: putting rubber into the tube and compressing it with a punch at the top to make the tube bulge into shape; filling the middle of the tube with liquid and relying on the pressure of the liquid to bulge the tube into the required shape. .

  In addition, there is another processing method that uses molds to produce ANSI B16.9 ASTM A234 WPB Carbon Steel Pipe Fitting Reducing Tees. The mold includes an upper mold and a lower mold. The lower mold is provided with a processing cavity, and the upper mold is provided with a processing block that matches the shape of the processing cavity, and the processing cavity is horizontal T-shaped. In addition to the T-shaped intersection, the intersection of the cross-sections of the processing cavity is semicircular, and the opening of the cross-section is located on the upper surface of the lower mold, thus changing the processing method of the ANSI B16.9 ASTM A234 WPB Carbon Steel Pipe Fitting Reducing Tee and processing two semicircular tee pipe fittings one by one. The openings of the two are welded, and the opening of the pipe joint is welded to increase the contact surface between the two and reduce the difficulty of welding. In addition, the semi-circular tee fitting is easy to place on the ground and does not wobble, further improving processing stability. It avoids the tendency of traditional nozzles to roll during processing.

  The processing methods of ANSI B16.9 ASTM A234 WPB Carbon Steel Pipe Fitting Reducing Tees are different. Professional processing equipment such as metal rods, pushers, commutators, brackets, etc. should be used. During the operation, in order to form the ANSI B16.9 ASTM A234 WPB Carbon Steel Pipe Fitting Reducing Tee blank, the metal rod is heated, pushed out with a jack and metal rod, and the pipe wall material is poured out naturally, and then a certain length of corresponding pipe section is welded to the reducing pipe formed by ejection. Pipe tee blank to produce the product. The special processing equipment used has simple structure and low cost in the processing method of reducing tee pipe fittings. The manufacturing of ANSI B16.9 ASTM A234 WPB Carbon Steel Pipe Fitting Reducing Tee does not require additional injection molding machines and injection molds, which can reduce the production cost of such pipe fittings and increase output. Therefore, this processing method is suitable for processing tee fittings with different specifications and different pipe diameters.
