Problems solved by technology

However, the intersection of the main pipe and the branch pipe of the welded tee forms a right angle, which greatly affects the flowability, and the weld seam at the intersection is the place where the stress is the most concentrated, and it is the weakest link of the entire pipeline. Welded tees are not allowed

Embodiment Construction

[0017] Example 1. The production specification is DN1000*DN800 STD (φ1016*9.53mm / φ813*9.53mm) tee fittings; that is, the material of the tee fittings is Q235, the wall thickness is 9.53mm, and the diameter D of the tee main pipe is 1016mm, d The diameter of the branch pipe of the tee is 813mm, the length C of the main pipe of the tee is 1498mm; the height M of the branch pipe is 711m;

[0018] (1) Select a piece of Q235 steel plate for cutting and blanking to obtain the upper tile material. The length of the upper tile material is L=1980mm, the width is B=1600mm, and the thickness is the same as that of the finished tee pipe fittings to be produced. The wall thickness is the same; use the rolling machine to roll the upper tile material into a U-shaped upper tile. The radius R of the U-shaped upper tile is 508mm, the height of the straight sides on both sides is 200mm, and the length of the U-shaped upper tile is 1600mm. ;

[0019] (2) Put the U-shaped upper tile into the furn...

Abstract

The invention relates to a production method for a three pipe fitting. The finished product of tee pipe fitting is produced by the following steps of: cutting one block of steel plate of the same material required by the tee pipe fitting to obtain an upper tile material and winding the upper tile material into a U-shaped upper tile; blistering and opening pores on the U-shaped upper tile and extruding a tee branch pipe at the pores; cutting one block of steel plate of the same material required by the tee pipe fitting to obtain a lower tile material and winding the lower tile material into a U-shaped lower tile; and finally splicing and welding the U-shaped upper tile and the U-shaped lower tile. The method has the advantages of greatly improving fluidity of medium, along with larger aperture of the produced tee pipe fitting and smooth transition between a main pipe and the branch pipe of the produced tee pipe fitting.

Description

1. Technical field [0001] The invention relates to a production method of a three-way pipe fitting, in particular to a tile-type production method of the three-way pipe fitting. 2. Background technology [0002] Tees are pipe fittings and pipe connectors, also known as pipe fittings or tee fittings, and tee joints, which are used at the branch pipes of the main pipeline; tees are divided into equal diameters and different diameters, and the connecting ends of equal diameter tees All parts are the same size; the size of the main tube of the tee with different diameters is the same, and the size of the branch pipe is smaller than that of the main tube. [0003] Tee is a kind of pipe fitting used at the branch of pipeline. For the manufacture of tees with seamless pipes or longitudinally welded pipes, there are currently three commonly used processes: hydraulic bulging, hot pressing forming, and welding forming. [0004] Using the hydraulic bulging process, the caliber of the...
