Running the numbers of pipe fitting is not always necessary to complete a job. If you have the experience and the eye to get the job done, without going through mathematical functions, that’s great. I admit that I rarely have to use sophisticated math to figure out my piping layouts. But, I do know how […]

ROLLING OFFSETS
Rolling offsets can be figured with a complex method or with a simplified method. since i assume that you are interested in the most accurate information that you can get in the shortest amount of time, i will give you the simplified version. The results will be the same as the more complicated method, but […]
Round Obstacles
You’ve just seen how to get around what many would see as a typical problem. Most offsets are used to get around square or rectangular objects. But, what happens when you have to bypass a round object, such as a pressure tank? Don’t worry, there is a simple way to get around most any problem, […]
GETTING AROUND PROBLEMS
Getting around problems and obstacles is part of the plumbing and pipe fitting trades. Few jobs run without problems or obstacles. As any experienced piping contractor knows, there are always some obstructions in the preferred path of piping. Many times the obstacles are ductwork, but they can involve electrical work, beams, walls, and other objects […]
SPREADING OFFSETS EQUALLY
If you take a lot of pride in your work or are working to detailed piping diagrams, you may find that the spacing of your offsets must be equal. Equally — spaced offsets are not only more attractive and more professional looking, they might required. You can guess and eyeball measurements to get them close, […]
BASIC OFFSETS
Basic offsets are all based on the use of right triangles. You now know about Set and Travel. It is time that you learned about a term known as Run. Travel, as I said earlier, is the distance between center of two offset fittings that creates the length of a piece of pipe. This pipe’s […]
FORMULAS FOR PIPE FITTERS
P lumbing and pipe fitting are similar, but not always the same. Modern plumbers usually work with copper tubing and various forms of plastic piping. Cast-iron pipe is still encountered, and steel pipe is used for gas work. Finding a plumber working with threaded joints is not nearly as common as it once was. But, […]
FINDING THE AREA AND VOLUME OF A GIVEN SHAPE
Finding the area of a given shape is also done with the use of formulas. It’s no more difficult than what we have already been doing. In some ways, finding the area is easier than finding the perimeter. Most anyone in the trades knows how to find the square footage of a room. When you […]
Triangle Perimeters
Triangle perimeters are not difficult to establish. The process is similar to the one used with squares, only there is one less measurement. To find the perimeter of a triangle, add up the sum total of the three sides of the shape. if you want a formula to use, it could look like this: P […]
A LITTLE GEOMETRY
A little geometry is needed in the plumbing trade. Whether you are working with roof drains, figuring floor drains, or doing almost any part of plumbing paperwork, you may be using geometry. I hated geometry in school, but i’ve learned how to use it in my trade and how to make the use of it […]
