Welding pipe is a process in which two pieces of metal are combined together by melting the surfaces and fusing them together to create a single piece of metal. The welded joint is commonly referred to as an “inch,” and it is usually expressed as x inches long or y inches long. If you’re planning on welding pipe or working with someone who does, then it’s important that you understand how to calculate weld inches on pipe correctly. There are several ways to do this, but they all come down to the same principle: You must know the diameter of the steel pipe because that determines its volume. Here we will explore how to calculate weld inches on the pipe so you can get started with your project right away!

**How To Calculate Weld Inches On Pipe?**

**1. Measure The Diameter Of The Steel Pipe**

To calculate weld inches on a pipe, you must measure the diameter of the steel pipe. This can be done using a tape measure or a caliper. You can also use an online calculator to do this for you.

**2. Multiply The Diameter By 1.084**

After measuring and calculating the diameter of the steel pipe, you need to multiply it by 1.084 to get your weld inches on the pipe measurement. After doing that, you have your weld inches on pipe measurement! If you have any questions or need help with this process, give us a call at 877-769-8239 and we will help you out!

**3. Calculate The Volume Of The Steel Pipe**

Once you have the weld inches on the pipe measurement, you must calculate the volume of the steel pipe. Remember that this is not a length measurement, so you must use a formula to get it.

The volume of Steel Pipe = Diameter x .9063 x Weld Inches on Pipe Measurement / 1440.

**4. Calculate The Length Of The Steel Pipe**

Finally, you need to calculate the length of the steel pipe. This is a simple calculation and you can do it quickly by using a formula that we have provided below. The length of the Steel Pipe = Volume x Length / 3.1416.

**What Is The Volume Of Welded Pipe?**

- Take the length of the welded pipe and multiply it by the diameter of the welded pipe.
- Divide this number by two. This gives you the total volume of welded pipe in cubic inches.
- Multiply this number by 0.5 to get a “wet” weld volume in cubic inches. Note that this is an approximate value, and it will vary depending on whether you are working with high-carbon steel or mild steel, as well as the thickness of your pipe and how long it is in inches.
- Multiply this value by 0.9 to get a “dry” weld volume in cubic inches.

These four steps help you calculate weld inches on the pipe and will help you determine how much welding material you will need for your project. We’ll go over these calculations and discuss other important information in the next section, but first, here is a quick video that explains the process in more detail.

**Calculating Weld Inches On Pipe Using Volume & Density Of Steel Pipe Material**

- To find out how many cubic inches or cubic feet (often referred to as “cubic”) of steel pipe you need, multiply the length of the pipe by its diameter or diameter in inches and add it to the volume of its material in cubic inches or cubic feet.
- For example, if you have a 3/4-inch diameter steel pipe that is 4 feet long and you’re using 10-pound steel, then you would multiply 4 x ¼ x 10 and add it to the volume of its material in cubic inches or cubic feet. The formula for this is (inches x inches x pounds)/12 = cubic inches/cubic foot.
- Example: If your pipe is 12 inches long and weighs 100 pounds, then it will take 100 / 12 = 8 feet to be welded together. In this case, it will take 8 x ¼ = 3 cubic feet of steel to be welded together in order for the weld to be complete.

- To find out how many pounds of steel pipe you need, multiply the length of the pipe by its diameter or diameter in inches, and add it to the volume of its material in cubic inches or cubic feet.
- For example, if you have a 3/4-inch diameter steel pipe that is 4 feet long and you’re using 10-pound steel, then you would multiply 4 x ¼ x 10 and add it to the volume of its material in cubic inches or cubic feet. The formula for this is: (inches x inches x pounds)/12 = pounds/cubic foot.
- Example: If your pipe is 12 inches long and weighs 100 pounds, then it will take 100 / 12 = 8 feet to be welded together. In this case, it will take 8 x ¼ = 3 cubic feet of steel to be welded together in order for the weld to be complete.

**Converting Millimeters To Inches**

- First, you need to know how many millimeters there are in each inch.
- Multiply the number of millimeters in an inch by 25.4 and you’ll get the number of inches there are in a foot.
- Divide that number by 25 to get the number of millimeters in a foot.
- Now to convert those millimeters into inches, multiply them by 25 and divide them by 2, because that’s how many inches there are in a foot (25 divided by 2 = 12). That gives you the inches per foot that we need to calculate the weld inch on a pipe: x inches per foot = y feet (or meters) in length.

**Conclusion**

Welding pipe is a necessary step in building many types of projects. If you are planning to purchase a welded pipe, then you may need to know how to calculate weld inches on the pipe. There are three important things you need to know if you want to calculate weld inches on a pipe: The diameter of the pipe, the length of the welded joint, and the density of the steel pipe. With this information, you can determine the volume of the welded pipe, which is the amount of space that the welded pipe takes up inside the joint. From there, you can convert the weight of the pipe to feet, the diameter of the pipe to inches, and the length of the welded pipe in inches to the diameter of the pipe in millimeters. Welding pipe is a complicated process, but as long as you know how to calculate weld inches on pipe, you won’t have any trouble!
