  ASME B16.9 Carbon Steel Butt Weld Reducing Pipe Fitting Tee is a pipe fitting relative to ASME B16.9 Carbon Steel Butt Weld Equal Pipe Fitting Tee, which refers to the branch pipe and the other two pipe fitting tees with different diameters. ASME B16.9 Carbon Steel Butt Weld Reducing Pipe Fitting Tee is widely used in the construction and maintenance of industries such as petrochemicals, liquefied gas, power plants, nuclear power, shipbuilding, papermaking, pharmaceuticals, food hygiene, urban construction, etc. So, do you know how the ASME B16.9 Carbon Steel Butt Weld Reducing Pipe Fitting Tee is produced? What production equipment is used for the production of ASME B16.9 Carbon Steel Butt Weld Reducing Pipe Fitting Tee?

  1. Attention should be paid to the use of molds and equipment in the production of ASME B16.9 Carbon Steel Butt Weld Reducing Pipe Fitting Tee

  In the previous production of ASME B16.9 Carbon Steel Butt Weld Reducing Pipe Fitting Tee, molds were used. During operation, the billet was first placed on the lower mold, then the upper mold was pressed down, and the shaft heads at both ends were pressed tightly against the end of the billet. Then, high-pressure liquid was introduced through the center hole of the shaft head, and under the combined action of high-pressure liquid and axial compression force, the required parts were obtained by bulging.

  However, the existing manufacturing equipment for ASME B16.9 Carbon Steel Butt Weld Reducing Pipe Fitting Tee is very troublesome when replacing molds, It is necessary to first uninstall the previously installed modules, then pre install the modules that need to be replaced, and then adjust the positioning to align the upper and lower molds. Then, use bolts to fix the upper and lower molds, which makes disassembly and replacement of modules very inconvenient. This increases the workload of workers and reduces work efficiency. Therefore, with the development of technology, specialized equipment has emerged in society.

  This type of processing equipment includes metal rods, top presses, commutators, brackets, and other components. During operation, a top out device is placed on the pipeline to heat the metal rod. When using a jack and metal rod to push it out, the pipe wall data naturally flips out to form a diameter reducing tee blank.

  Then, a certain length of pipe section corresponding to the standard is welded to the diameter reducing tee blank formed by the top out, producing the final product. This specialized processing equipment, The structure is simple, the cost is low, and the manufacturing of reducing tee fittings does not require other injection molding machines and molds, which can reduce the production cost of such fittings and increase production power.

  2. Attention should be paid to process parameters in the production of ASME B16.9 Carbon Steel Butt Weld Reducing Pipe Fitting Tee

  The current, voltage, speed, etc. of the ASME B16.9 Carbon Steel Butt Weld Reducing Pipe Fitting Tee during the welding process will directly affect the welding quality. Excessive or insufficient pressure during the extrusion forming process of the reducer tee can cause poor forming, leading to repair or scrap.

  Therefore, the pushing speed of the hot pushed tee should be suitable for the heating speed to the specified temperature, otherwise it may cause poor forming of the tee; In the forming of a ASME B16.9 Carbon Steel Butt Weld Reducing Pipe Fitting Tee, several deformations are required to achieve the required shape and size, and the influencing factor is the mold core. Therefore, controlling the shape and size of the mold core is crucial for the pipe fitting tee.
