What are fittings?
1 : an action or act of one that fits specifically : a trying on of clothes which are in the process of being made or altered. 2 : something used in fitting up : accessory. 3 : a small often standardized part an electrical fitting.
What are the types of fittings?
There are many different kinds of fittings, made from a variety of materials: some of the most common types are elbows, tees, wyes, crosses, couplings, unions, compression fittings, caps, plugs and valves.
What are the different pipe fittings?
Common piping and plumbing fittings
- Adapter.

- Nipple.
- Reducer.
- Double-tapped bushing.
- Tee.
What is piping fitting?
Pipe Fittings are Piping component that helps in Changes the direction of the flow such as elbows, tees. 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.
How do I identify a pipe fitting?
Measure the Outside Diameter (OD) of your pipe or pipe fitting:
- Wrap a string around the pipe.
- Mark the point where the string touches together.
- Use a ruler or measuring tape to find the length between the tip of the string and the mark you made (circumference)
- Divide the circumference by 3.14159.
How do you read a pipe fitting size?
To determine the size of a pipe, the outside diameter of each pipe or fitting must be measured and compared to the table for size identification. For example, a 3/4″ NPT pipe thread has an outside diameter of 1.050 inches. Each thread size has a defined number of threads per inch (TPI).
How do you determine your fitting size?
Lay your fitting over the appropriate drawing to determine what size fitting you have. Use the diagram below to find pipe thread size. Place fitting against base line; read fitting size where it intersects the vertical line.
What is standard pipe size?
Steel Pipe Sizes – Schedule 40
| NPS | Outside Diameter (in) | Weight (lb/ft) |
|---|---|---|
| 1 | 1.315″ | 1.68 lb/ft |
| 1-1/4 | 1.660″ | 2.27 lb/ft |
| 1-1/2 | 1.900″ | 2.72 lb/ft |
| 2 | 2.375″ | 3.65 lb/ft |
How far does a pipe thread into a fitting?
If you are using 1/2-inch pipe, add 7/16 inch per end; and add 1/2 inch per end for 3/4-inch pipe. Therefore if you plan to use 3/4-inch pipe to join two fittings 36 inches apart, you would need a pipe 37 inches long (adding 1/2 inch on either end to allow for penetration into the fittings).
What is standard pipe thread?
Commonly used sizes are 1⁄8, 1⁄4, 3⁄8, 1⁄2, 3⁄4, 1, 1 1⁄4, 1 1⁄2, 2, 2 1⁄2, 3, 4, 5, and 6 inch, as pipe and fittings by most U.S. suppliers. Sizes smaller than 1⁄8 inch are occasionally used for compressed air, while sizes larger than 6 inches are often joined by other methods.
How far do NPT threads engaged?
As a general guideline, after hand-tight engagement, tighten 2 full turns for sizes up to 1 inch for NPT thread fittings. You should have between 3.5 and 6 engaged threads. Any number outside of this range may indicate either under or over tightening of the joint or out of tolerance threads.
What is the take off for a 2 inch threaded 90?
2” 90’s take off 1 3/4 ” . For accurate installation make fitting on one end of pipe then measure center to center and takeoff the other fitting, mark, cut , and thread. This way you only have to worry about thread make up on one end.
What is fitting allowance?
Fitting allowance: the dimension from the end of a pipe inserted into a fitting to the outlet of the fitting. Thread engagement: the length of pipe inserted into a fitting to the point where the threads are snug and a watertight seal can be achieved.
What is the takeoff on a 6 inch 90?
short radius or long? and what diameter pipe? typically, the takeout is one and a half times the nominal pipe size. so a 6 inch long radius elbow takes out 9 inches.
What is a pipe takeoff?
First, a definition of “take off”: The length of pipe to be removed (taken off) such that a pipe and a fitting make a specific length. The term is a concept shorthand used by pipefitters and plumbers. Take-offs in general are specific to pipe construction (PVC, copper, etc.) and is a function of diameter.
How do you calculate pipe takeoff?
Take your pipe size and divide that number in half 3 times. Take the second and 4th number and add them together. That is your take off.
Does an offset account reduce monthly repayments?
Does an offset account reduce my monthly repayments? Your minimum monthly repayments will generally stay the same no matter how much money is in your offset account. Having money in an offset account just means more of your repayment amount will go towards paying down the loan principal and less towards interest.
What is the formula for a 22.5 degree offset?
For any fitting angle that is 22.5 degrees, the true offset is multiplied by 2.613 to get the answer for the diagonal. The setback for fitting a pipe equals the true offset multiplied by 0.577 for a fitting angle of 60 degrees. The true offset multiplied by 1.000 equals the setback for a 45-degree fitting angle.
What is the formula for a 45 degree offset?
The amount of offset is determined by the length of the pipe between the two 45s. Measure the offset then multiply that by 1.41 (the square root of 2), then take off for the fittings (the amount of the travel distance that both 45°s will take up).
How do you work out a 22.5 degree angle?
For this you must have to draw and angle of 90°.
- Then you have to make half of this,you will get two of 45° and 45°.
- Then again make half of one 45° angle and you will get desired 22.5° angle.
How do you calculate the degree of a pipe?
Calculate elbow center to end dimension for 4 inch nominal pipe diameter elbow at 60 degree angle, cut from 90 degree LR elbow. From ASME B16. 9, center to elbow dimension for 4 in elbow is 152 mm. Length = 87.757 i.e. 88 mm Approx.
How do you calculate the angle of a pipe bend?
4-Point Saddle Bend Calculation The “d” represents the angle at which the pipe is bent. No matter how the tube is bent in this configuration (or how the triangle is oriented), one of the angles of the triangle will be 90°; the other angle will depend on the first angle (d), and can be calculated as (90 – d).
How do you measure a 90 degree pipe bend?
To use the deduct figure, measure the distance to the far edge of the 90 and subtract the deduct figure. If ½” pipe is being bent and the distance is 56″ place a mark on the conduit at 51″; this is where the bender will be placed. Work the bender onto the conduit with the conduit mark at the arrow of the bender./span>
