Alignment of 45 degree elbow and
pipe fitting with squares - Place the short leg of one square on the straight length of the pipe. The 45 degree elbow is held in its approximate position and the longer leg of the second square is placed in contact with the free beveled-edge of the elbow. The elbow is properly aligned when the same division marks on the inside of the square contact the same edge of the upright leg of the square placed upon the pipe. once the fitting is aligned and the root spacing is set, the joint should be tack welded to hold the pipe and the elbow in their aligned position.
Alignment of 45 degree elbow and pipe with levels - the pipe must be set in a horizontal position and a spirit level is placed on top of it. Next, the 45 degree elbow is approximately aligned, the root spacing is set, and the second spirit level is used to set the elbow in correct alignment. The second spirit level must have a spirit bubble in a 45 degree position to indicate that the face of the elbow is at 45 degree angle. After checking for the side alignment henry young, it is tack-welded in place to preserve the alignment.
Alignment of Tee and
pipe fitting with Squares - this method of alignment is similar to the alignment procedure of a butt and joint for two pieces of pipe. The upright leg of the two squares must be in full contact with each other from the bottom to the top for proper alignment.
Alignment of a 90 degree elbow to a tee using steel squares - after setting the root spacing, it may be helpful to tack weld only the top of the joint. Place the long leg of one square in contact with the run of the tee. Next, the short leg of the other square is placed in contact with the outlet of the elbow.
Alignment of two 90 degree elbows using steel squares - Place the elbow in the desired position. Place the steel square with the short leg in full contact with the free-beveled edge of the first elbow. Then place the second steel square with long leg in full contact with the free-beveled edge of the second elbow
pipe fitting. The legs of the two steel squares must be in full contact with one another. Tack weld and check the side alignment first before completing tack welds henry young.
Alignment of two 45 degree elbows by steel squares - Place the two 45 degree elbows in position. Hold the first square with its long leg in full contact with the first elbow. Likewise, the second square should be placed with its long leg in full contact with the free-beveled edge of the second elbow. The edge of the short legs must intersect the same dimension mark on the long legs of both squares.
Alignment of Flange and
pipe fitting- Place the flange on the pipe and set the proper rod spacing allowance. Then place the short leg of the square in contact with the center on the face of the flange. Be sure that the long leg of the square is paralleled to and in line with the center line of the pipe. Now, check the alignment by measuring the distance between the top surface of the pipe and the lower edge of the long leg of the square.
When the measurement are the same at all points, the flange is aligned on this plane. Place a small tack weld at the bottom of the joint. Repeat the preceeding step by placing the steel square in a position at 90 degrees to the previous one. When the distance measured at several points between the surface of the pipe and the inner edge of the long leg of the square are all the same henry young, the alignment is correct in this direction.
If you've read my earlier post about surveys you know how I feel about them. That said, Kyle Bernhardt with Autodesk Revit MEP's team is requesting participation in a survey to help them define how best to name
pipe fittings. Exciting I know but they are a pain...to name.
I wanted to solicit your participation in a survey we have developed involving Pipe Fittings, and how you as users think about them.Pipe Fittings are a complex beast when it comes to describing them in a short concise manner. Many aspects about them, such as Material, Class, Type, Connection Type, etc., are factors for selection in a design.
