Changes the size of the pipe such as reducers, reducing tees. Connect different components such as couplings and stop the flows such as Caps. There are different types of pipe fitting used in piping.
You can see the chart above that list most widely used standard pipe fittings. These standard fittings are either forging or wrought. Only seamless pipes are used to produce wrought fittings. Large diameter welded fittings are manufactured from the plate. The Elbow is used more than any other pipe fittings. It Provides flexibility to change the pipe direction. However, it Can be cut to any other degree.
Elbows are available in two radius types, Short radius 1D and Long radius 1. Available in long and short radius form. In long radius elbow, centreline radius is 1. Normally long radius elbows are used in piping as pressure loss is less as compared to short radius elbow. It required more space than short radius elbow.
In short radius elbow, centreline radius is same as the nominal size of the pipe or you can say one times the diameter of the pipe. Short radius elbows are used under limited space application. However, it has a high-pressure drop due to a sudden change in the direction of flow. The 90 reducing elbow is designed to change direction as well as reduce the size of pipe within a piping system. The reducing elbow eliminates one pipe fitting and reduces the welding by more than one-third.
Also, the gradual reduction in diameter throughout the arc of the reducing elbow provides lower resistance to flow and reduces the effect of stream turbulence and potential internal erosion. These features prevent sizeable pressure drops in the line. Long radius pipeline bends are used in fluid transportation line which required pigging.
Here, D is the pipe size. Miter bends are not standard pipe fittings they are fabricated from pipes. Use of miter bend is restricted to the low-pressure water line. Returns are used in the heating coil, heat exchanger, tank vent etc. Pipe tee is used for distributing or collecting the fluid from the run pipe. It is a short piece of pipe with a degree branch at center.HDPE is a durable, flexible plastic. The insoluble material is weather-resistant, shock-resistant, and abrasion-resistant.
HDPE is also highly affordable, created from petroleum under high heat. Rather than crack, HDPE is more likely to tear under pressure, reducing overall damage.
The material is also recyclable, producing useful if less sturdy plastic. The trickiest factor when working with HDPE is bonding, which requires intense heat and precision.

The first method is a hit-or-miss process and requires an experienced fitter to do a good job; the second method is one of precision and is the better way. In actual practice, a combination of the two methods will, in some cases, save time and give satisfactory results. Working from a drawing with all the necessary dimensions has certain advantages. Especially in the case of a big job, all the pipe may be cut and threaded in the shop so that at the place of installation the only work to be done is assembling.
In making a drawing, the measurements are based on the distances between the centers of fittings. The data necessary to locate these centers are given in a more general dimension drawing with an accompanying table such as the one illustrated in Table These dimension drawings and tables should be the ones corresponding to the make of fittings used; otherwise, there might be the possibility of slight variation.
In general, however, the different makes are pretty well standardized. Figure illustrates how the actual length of pipe connecting the two fittings is obtained. The actual length of pipe is equal to the distance between centers of fittings minu s twice the distance from the center of the face of the fittings plus twice the allowance for threads. This allowance called A in Figure corresponds to the values given in the accompanying table see Table Note that the dimension A in Figure is the same as dimension C in Figure A working drawing showing centerlines and distances between centers of an installation is shown in Figure This gives all the information excep t the actual length of the pipes.
Problem Find the length of the pipe connecting the 2-inch elbows in Figure An example of an offset is illustrated in Figure As shown here, the problem is an obstruction Esuch as a wall, blocking the path of a pipeline L.
It is necessary to change the position of pipeline L at point A to some parallel position such as line F in order to move around the obstruction. By determining the distance BCthe pipe fitter will be able to fix point A so that the two elbows A and C will be in alignment. Of course, in the triangle ABCthe length of pipe AC and either offset AB or BC that may be required are quickly calculated by solving the triangle ABC for the desired member, but this involves taking the square root, which is not always easily understood by the average worker.
Alternative methods are suggested in the fol- lowing sections. Therefore, if offset AB is 20 inches long, offset BC also must be the same length. Note that the value that is, In other words, pipe H as calculated by this equation is too long and must be shortened so that the elbows will fit.
Actual length is obtained by deducting the allowance for projection o f the elbows from the calculated length. For these, the distance between elbow centers points A and C can easily be calculated with the following procedure: 1. Determine the angle of the elbow. Determine the elbow constant equivalent to its angle.
Multiply the elbow constant by the known offset. In Figureeven though only offset AB is known, it is possible to determine the length of the other offset BC and the distance between elbow centers AC. Substituting values in the second equation, you have the following: Fourth Method Offsets may also be calculated by using basic trigonometry.

Isometrics are usually drawn from information found on a plan and elevation views. The symbols that represent fittings, Valves and flanges are modified to adapt to the isometric grid.
The Iso, as isometric are commonly referred, is oriented on the grid relative to the north arrow found on plan drawings. Because iso's are not drawn to scaledimensions are required to specify exact lengths of piping runs.
Pipe lengths are determined through calculations using coordinates and elevations. Vertical lengths of pipe are calculated using elevations, while horizontal lengths are caculated using north-south and east-west coordinates. Piping isometrics are generally produced from orthographic drawings and are important pieces of information to engineers. In very complex or large piping systems, piping isometrics are essential to the design and manufacturing phases of a project.
Piping isometrics are often used by designers prior to a stress analysis and are also used by draftsmen to produce shop fabrication spool drawings. Isometrics are the most important drawings for installation contractors during the field portion of the project.
A pipe into a isometric view, is always drawn by a single line. This single line is the centerline of the pipe, and from that line, the dimensions measured. So, not from the outside of a pipe or fitting. The image below shows a orthographic view of a butt welded pipe with three sizes A, B, C. As you can see, this drawing is very simple and quick to implement.
The red lines show the pipe, the black dots are the butt welds and A, B and C are the dimensions of front to center line and center line to center line.
A second reason to made isometrics; if a pipe should be drawn in several planes north to south, then down and then to the west, etc. In a orthographic view it is not a problem if the pipe runs in one plane, but when a pipe in two or three planes to be drawn, a orthographic view can be unclear.
Another reason why isos are preferred, is the number of drawings that for orthographic views should be made. For example: for a complex pipeline system, 15 isometrics must be drawn. I've never tried, but I think for orthographic views maybe 50 drawings are needed to show the same as the Iso's. The image below show the presentation used in drafting. The isometric view clearly show the piping arrangement, but the plan view fails to show the bypass loop and valve, and the supplementary elevation view is needed.
Below are some examples of isometric drawings. The auxiliary lines in the shape of a cube, ensure better visualization of the pipeline routing.
