Tee pipe is a kind of chemical pipe fitting. This is a pipe joint with three openings. One import, two exports, or two imports and one export. Tees are made of plastic, glass, steel castings, copper castings and iron castings, mainly because the media it conveys are different. The tee has equal-diameter nozzle and different-diameter nozzle, which are mainly used to change the direction of fluid. Used in medicine, water conservancy, construction and other fields. So how do you make a tee? This article will teach you how to make a tee.

Tees are pipe fittings used in pipeline branches and branches. According to the similarities and differences between the main pipe and the branch pipe, it can be divided into the same diameter tee and the different diameter tee, and according to the included angle (α) between the branch pipe axis and the main pipe axis, it can be divided into the orthogonal tee (α = 90) and the oblique tee (α

Manufacture of 1 equal diameter orthogonal tee

Before marking, draw a positioning cross on the main pipe and branch pipe, and gently wash it with a sample punch. Then align the center of the female template and the male template with the center line of the pipeline, draw the cutting line, and then cut. When cutting, it should be carried out according to the requirements of groove. All grooves shall be made on the branch pipe. The bevel angle of fillet weld is 45, and the bevel angle of butt weld is 30. The groove angle gradually decreases from fillet weld to butt weld (i.e. sharp corner), and the transition is even. When assembling tees with the same diameter, it is required that the size of the opening on the main pipe should match the diameter of the branch pipe, and the internal seam at the weld should be uniform. During assembly, the included angle between the branch pipe and the main pipe should be corrected to 90 with a wide square, then fixed by spot welding, and finally welded.

2. Fabrication of reducing orthogonal tee

Before scribing, first draw positioning crosshairs on the main pipe and branch pipes, then punch holes gently with a sample punch, align the center of the male and female templates with the center line of the pipeline, and draw a secant, and then cut. During assembly, the angle between the branch pipe and the main pipe should be corrected to 90 with a wide square, and the end of the branch pipe should be flush with the inner wall of the main pipe, and the branch pipe should not extend into the inner cavity of the main pipe.

3. Fabrication of oblique tee with the same diameter

The marking, blanking and splicing of the same diameter oblique tee are the same as those of the same straight tee, and the groove can be flexibly mastered according to the included angle and opening size to meet the welding requirements. Generally, both the main pipe and the branch pipe are in the upper part of the obtuse angle, so they can all be slotted. The oblique angle is 30 ~ 35, the lower half is 30 at the sharp corner, and then gradually transitions to 45. After gradual and uniform transition, the oblique angle at the included angle between the two pipes is the largest.

4. Fabrication of reducing oblique tee

The marking, blanking and splicing methods of different diameter oblique tee are the same as those of the same diameter tee, but the difference is that when the branch pipe is inserted into the main pipe, its end should be flush with the outer wall of the main pipe, and the end should not extend into the main pipe cavity.

5. The marking, blanking and assembly of equal-diameter and equal-angle tees are the same as those of ordinary tees, except that the included angle of the tees is 120, which should be carefully checked with a protractor.

6. The marking and blanking of the equal-diameter tee at any angle are the same as those of the equal-diameter tee. When assembling, carefully check the required angle with a protractor.

The manufacturing method of tee pipe has been introduced, so you can refer to it. Tees are used for water, oil and various liquid pipelines, and also for gas pipeline networks. Mainly used to change the direction of fluid. It is a practical chemical pipe fitting. We often see it in our daily life, such as the disposable stethoscope of doctors in hospitals and the tubes for intravenous infusion. There are also some families whose hand sinks and sewer pipes are also tee pipes. Therefore, the three-way pipe is widely used.
