What is a lateral tee?

Typical tee fittings resemble the alphabet ‘T’ and the branch forms a perpendicular 90-degree formation to its header. However, the branch of a Lateral Tee will branch out at 45 degrees.

What is the carbon steel lateral wye branch formula?

There are 2 branch formule to be used for a lateral wye branch

  • R / tan (A/2) = Long cut
  • R x tan (A/2) = Short cut

How to make a 45 degree lateral tee?

It isn’t easy to manufacture a seamless lateral tee because it is not symmetrical, unlike many fittings. The production process includes forging the material. The first step to producing the fitting is to forge the steel billet, followed by machining. During machining, there are three openings created on the fitting – one for fluid inflow and the remaining two for outflow.

How to calculate the surface area of stainless steel lateral tee?

To calculate the surface area of a lateral tee, the fitting needs to be split up into 3 components. Two cylinders(header and branch) and a sector i.e.- the area that connects the branch and the pipe.

  • The surface area of a cylinder = 2πrh+2πr2
  • Here r = radius and h = height.
  • Both the branch and the header will have different values. The next step is to calculate the area of a sector using the following formula – /360o (r2). Here theta is the angle of the sector. Once you have all three values, calculating the surface area (lateral tee) becomes simple.
  • Surface area of the branch (SB) = /360o (r2) + 2πrh+2πr2
  • The surface area of the header pipe (SH) =/360o (r2) – 2πrh+2πr2
  • The header pipe will have reduced some reduction in its surface area because it is attached to the branch. The sum total of both the branch and the header pipe will give you the surface area of a lateral tee.

45 degree y branch pipe fitting lateral tee hole marking formula

In order to mark a hole in a lateral tee, you need to first calculate the circumference of the branch. Once you have the details of the perimeter, take a straight sheet and cut it to the width of the circumference and the length keeping in mind the length of the branch. The next step would be to divide the entire width of the circumference by an even number like 8 or 16. Since the tee is angled at 45 degrees, the point of contact between the branch and the header will have multiple heights. These numbers could be obtained with the help of software. Start plotting and labelling the different heights on the lines. Draw a continuous line along the plotted areas to form the curve of the branch. Trimm off the excess sheet until it resembles a branch. After the branch has been created, the next step is to mark the hole on the header. This can be done in 2 ways. The first technique is to trace the outline of the branch curve over a header draft or draw lines on the draft that correspond to the lines of the branch. In the second technique, illustrate a centre line horizontally across the header draft. Mark a reference line such that it remains perpendicular to the horizontal line. Then, using the measurements given by the software, illustrate several lines for the different height measurements that will match the height values of the branch draft. On these lines, points need to be plotted with the different software-generated values (length). Connect these points to form an ovular-shaped pattern. The second last step is to check if the oval portion matches the shape of the branch marking. Lastly, the oval portion is to be trimmed out.
