How to do the cable tray tee What is the formula

Turn left|Turn right.

Hello! The tee elbow you need to make should look like this! Tees are made of equal diameter tees, and there are also different diameter tees! Just learn how to calculate! There is also a cutting method, you can do various specifications of bridge elbows!!

It's actually very simple! A lot of people do it now! As long as you can do tee, four-way elbow will also do! If you are on a construction site, it is recommended that you ask the teacher, if you are self-taught, there are tutorials online! Hope it helps!

The practice and formula of the horizontal tee of the bridge The first method: h (r1 -(r2 sinbn) ) the first line: the center height of the tee branch pipe minus the radius of the pipe = 1 line The second line:

75- Third line: 75- Fourth line: 75- Second method:

r1 r1 -(r2 sinbn) ) 1st line: 0 2nd line: 3rd line:

Fourth line: Note: Main Outer Radius - Main Outer Radius - (Branch Inner Radius sinbn)).

Bridge horizontal tee.

Tray tee production:

1. Straight section: indicate the full length, number of layers of the bridge, elevation, model and specification. Bend point and branch point: indicate the model and specification of the turning adapter used. Lifting section: indicate the elevation change, which can also be represented by a local sample or section drawing.

2. Determine the direction: according to the building layout plan, combined with the setting of air conditioning pipelines and electrical pipelines, convenient maintenance, and the density of cable routing to determine the best route of the cable tray.

3. Load calculation: calculate the weight of the cable per unit length on the longitudinal section of the main trunk of the cable tray.

4. Determine the width of the tray: determine the model and specification of the cable tray, the length of the supporting arm, the length and spacing of the pillar, the width and the number of layers of the tray according to the number of cables, the diameter of the cable and the spacing of the cable.

5. Determine the installation method: determine the fixing method of the bridge according to the setting conditions of the place, choose the suspension type, the vertical type, the side wall type or the hybrid type, the connectors and fasteners are generally matched, in addition, the corresponding cover plate is selected according to the bridge structure.

6. Draw the flat and cross-sectional drawings of the cable tray, and the local parts should also draw the space map and list the material table.

7. Determine the size of the bridge at hand, 200*100 bridge, and make a 30-degree uphill elbow. With the help of a mobile phone computer, the blanking size is calculated. Through the previous step, the blanking size is calculated.

The next step is cutting, and the three lines are the blanking size, which can be combined to make a bridge tee.

How to represent the horizontal small and medium-sized tee in the cable tray, hello, the expression method is as follows: for equal diameter tee, for example, T3 tee means that the outer diameter is 3 inches of equal diameter tee. For reducing tees, for example, t4 4 means reducing tees with a diameter of four inches and a reducing tee of inches.

The material is generally 10 A3 Q235A 20g 20g 16MN ASTM A234 ASTM A105 ASTMA403, etc., tee, outer diameter range, from 26 60 for welding tee. Wall thickness 28, 60mm. The wall thickness and other chain grades are:

sch5s、sch10s、sch10、sch20、sch30、sch40s、std、sch40、sch60、sch80s、xs；sch80、sch100、sch120、sch140、sch160、xxs。Reducing tee, generally a professional term, tee for pipe fittings, pipe connectors, used in the main pipeline to branch pipes. Reducing tee is a kind of tee, tee Yuanyu has two kinds of general equal diameter tee and different diameter tee.

Because the three ends can be connected to the pipe. I hope my answer is helpful to you, and finally I wish you good health and a happy mood again! <>

Summary. Dear, hello, I am glad to answer the bridge 400 200 bridge tee for you to do this, generally speaking, when the main line bridge with tee, should start laying the bridge at the location of the tee. Then lay the bridge at both ends and the bridge at the tee end.

Make 400 straight-through, and make a 200 three-way in the middle. The other is to make 400 into a curved pattern, and make a 200 diameter straight at the other end. This is a straight 400 to the front to 200 and indirect.

How to do bridge 400 200 bridge tee.

Dear, hello, I am glad to answer the bridge 400 200 bridge tee for you to do this, generally speaking, when the main line bridge with tee, should start laying the bridge at the location of the tee. Then lay the bridge at both ends and the bridge at the tee end. The 400 is made straight, and the middle air transport is a 200 three-way out.

The other is to make 400 into a curved pattern, and make a 200 through the other end. This is a straight 400 to the front to 200 and indirect.

Dear, if my answer is helpful to you, please also give a thumbs up (comment in the lower left corner), look forward to your like, your efforts are very important to me, and your support is also the driving force for my progress. If you feel that my answer is still satisfactory, you can close the void reed and click on my avatar for one-on-one consultation. Finally, I wish you good health and a good mood!

The bridge of 400 makes 3-way, what is the size.

26*219*426mm

The pro is 426*219*426mm

Tees are pipe fittings and pipe connectors. It is also called pipe fitting tee or tee pipe fitting, tee joint, which is used in the main pipeline to branch pipe. Stainless steel equal-diameter tee.

Tees are divided into equal diameter and different diameters, and the end of the pipe of equal diameter tee is the same size; The size of the main pipe of the reducer tee is the same, while the size of the branch pipe is smaller than that of the main pipe. Tee is a type of pipe fitting used at the branch of the pipeline. For the use of seamless pipe to manufacture tees, there are two kinds of processes usually used at present: hydraulic expansion and hot press forming.

a.Hydraulic expansion The hydraulic expansion of tee is a forming process that expands out of the branch pipe by axial compensation of metal materials. The process is to adopt a special hydraulic press, inject liquid into the tube blank equal to the diameter of the tee, squeeze the tube blank through the synchronous centering movement of the two horizontal side cylinders of the hydraulic press, the volume of the tube blank becomes smaller after being extruded, the liquid in the tube blank increases with the volume of the tube blank becomes smaller, when the pressure required for the expansion of the tee branch pipe is reached, the metal material flows along the inner cavity of the mold and expands out of the branch pipe under the dual action of the liquid pressure in the side cylinder and the tube blank.

The hydraulic expansion process of tee can be formed at one time, and the production efficiency is high; The wall thickness of the tee and shoulder has been increased. Due to the large tonnage of equipment required for the hydraulic expansion process of seamless tee, it is mainly used in the manufacture of standard wall thickness tee less than DN400 in China. Its suitable forming materials are low carbon steel, low alloy steel and stainless steel with relatively low cold work hardening tendency, including some non-ferrous metal materials, such as copper, aluminum, titanium, etc.

b.Hot press forming Tee hot press forming is to flatten the tube blank larger than the diameter of the tee to the size of the tee diameter, and make a hole in the part of the stretched branch pipe; The tube blank is heated, put into the forming die, and the punch of the stretched branch pipe is loaded into the tube blank; Under the action of pressure, the tube blank is radially compressed, and in the process of radial compression, the metal flows in the direction of the branch pipe and forms a branch pipe under the stretching of the die. The whole process is formed by radial compression of the tube blank and the stretching process of the branch parts.

Different from the hydraulic bulging tee, the metal of the hot-pressed tee branch is compensated by the radial movement of the tube blank, so it is also called the radial compensation process.

The production method is as follows:
