How to cut a 45 degree round pipe

How to cut a round pipe for 45 degree welding

To weld one round pipe to another at a 45 degree angle, you need to trim it each time for a tighter fit.

In this review, the author shows how to make a simple template that will allow you to spend less time fitting round pipes.

The first step is to make a sample from which you can make a template.

To do this, the author cuts off a pipe of the required diameter at an angle of 45 degrees.

We also recommend reading: how to make a mini machine for trimming saddles at the ends of pipes.

After that, we adjust the workpiece so that it fits as tightly as possible to the pipe.

The main stages of work

At the next stage, we cut off a sheet of paper and wrap it around the workpiece.

Press firmly and smooth with your fingers so that the place of the cut is “imprinted”. We wrap the edges of the sheet inside the pipe.

Then we remove a sheet of paper from the pipe, unfold it and draw a pencil around the resulting contour. Cut with scissors.

The result is a reusable template by which you can make markings on other blanks.

In the same way, you can make a paper template to cut round pipes for welding at an angle of 90 degrees.

For more information on how to make such simple templates and how to use them, see the video below.

Pipe cutting at an angle of 45 and 90 degrees

If you need to cut the pipe at an angle of 45 degrees, which is more often required when laying water, heating pipes. Steel, cast iron pipes that are cylindrical in shape are often used. In installation work, rectangular or shaped pipes are used. However, the pipe of the angle grinder should be cut correctly so that it can be easily connected later. Therefore, you should carefully mark the pipe.

Some craftsmen try to mark the place of the cut using a tape measure, but we warn you that the result is likely to be negative. And for a positive result, consider the following professional recommendation.

Take a sheet of paper or cardboard, preferably A4, fold it diagonally and wrap it around the pipe where you plan to cut it evenly. The edges of the paper must be in perfect alignment with each other. And the side of the paper that is closer to the end of the pipe was perpendicular to the axis. Then mark the cut line in a circle.

If you need to cut exactly at an angle of 90 degrees, then solve the problem quickly using paper or masking tape again. Wrap around the pipe so the ends match. Make even lines and saw off.

How to cut a profile pipe straight?

Masters advise using a square when cutting a profile pipe. To do this, apply the square in turn to the sides, and turn and mark with smooth movements. After action, fix the pipe and cut. Prepare yourself a template that will come in handy in the future and save time. It is better to produce an angle grinder, so the cut will be smoother.

How to cut a cast iron pipe?

When working with a cast iron pipe, keep in mind that it is a brittle material. Therefore, we will point out a way with which it will be possible to cut such a metal without damage.

Before starting work, make notes for the cut, just like with steel pipes. Place a piece of wood for support. Run an angle grinder around the circumference of the pipe making small cuts. Then take the chisels, insert into the groove and hit hard with a hammer. Note that bakelite-based cutting discs are used to cut cast iron pipes.

If you do not have an angle grinder at hand to cut a cast-iron sewer pipe or other purposes, use a metal hacksaw, chisels or special pipe cutters.

How to cut a gas pipe?

Cutting a gas pipe is dangerous, so it is best to entrust it to professionals. But if you are confident in the strength, then to cut the metal, take an angle grinder, welding, hacksaw, gas welding.

  • Shut off the gas riser before work. Then release the rest of the gas from the pipe. To do this, set fire to the gas in the burners and wait for it to go out.
  • After the steps taken, cut. Using the welding method, the metal base burns out when exposed to high temperature. The result is fast and effective. But remember that cutting or rooting gas pipes again requires experience.

Methods for cutting large diameter pipes

There are a number of reliable tools available for cutting large diameter pipes such as sewers. Let’s consider some of them in detail below:

  • An angle grinder is an inexpensive and affordable option, but it is considered not the safest when working with such materials. Once you decide to use this method, then be careful and use protective equipment.
  • A roller machine (pipe cutter) is such a tool adapted for such manipulations. The device is attached and material removal begins. The clamping force is adjusted using mechanical devices. It is important to note that the models of the machine differ in shape, so consider the ratio of dimensions to the pipe before use.
  • Flame cutting is the most popular option for cutting large diameter pipes, sheet metal. The cut occurs due to the action of a high intensity flame, the metal melts and leaves the cut zone with a gas flow. This method is convenient and effective.

How to cut a pipe lengthwise correctly?

A quick way to cut a pipe lengthwise with an angle grinder:

  • Focus on the markup.
  • Use for such a case the painter’s thread, which has found distribution when marking walls.
  • Before starting work, fix the pipe and with small movements, carefully saw the pipe.
  • Better not to rush, but delicately and slowly process the parts of the pipe, so the cutting disc will not jump off the marking lines. Remember safety.

How to cut thin-walled pipes?

Thin-walled pipes are made of non-ferrous metals: aluminum, copper. Such work should be done delicately, since there is a high probability of deformation of the material. Fillers such as sand are used for cutting. Actions can be carried out using an angle grinder, a special machine.

degree, pipe

Summing up, we emphasize that cutting metal pipes is a complex process, but anyone who wants to enhance it can enhance it. With the advice of a professional, you can easily cut pipes in a variety of sizes and materials. Also remember to use a file or emery paper to clean the edges of the pipes after cutting. And the most important thing to remember when starting such actions is safety precautions. Wear a special suit (casing), mask or goggles when getting started. Hands should also be reliably protected from sparks, so use thick gloves.

How to cut a cast iron pipe

The main difference between cast iron and ordinary steel is its high brittleness and large wall thickness; its accurate cutting must be performed in the following sequence:

  • A marking corner is drawn using a template using a scribe, for

supports under the part put a wooden board or board.

  • Perform an angle grinder shallow cut of the surface along the entire perimeter.
  • Further, the groove is deepened in several passes until the two parts are completely separated.

Collar insert

In order to obtain branches of metal pipelines in the form of tees, a collar insert is used, for which it is necessary to cut the edge of a round pipe adjacent to the walls of another at a right angle. To implement the method, proceed as follows:

  • cut the edges of the workpiece at right angles as described earlier.
  • On a round end surface, four equidistant points are marked with a marker, located at angles of 90 and 180 degrees to each other.
  • The circumference is measured, the resulting diameter is divided by 3. From two diametrically located points, the resulting distance is laid, after which these points are connected to two other smooth arc, drawing the fishing line with a marker.

For industrial use

In industry, large-diameter pipelines are used to transport liquids and gases, therefore, pipe cutting machines have a large weight and dimensions. There are also manual pipe cutters of a rotary and clamping principle of operation. In the first case, the cutting rollers rotate along a circular surface using a repositionable handle, in the second version, the cutting is carried out by arcuate plates, which gradually shift when rotating.

Cutting at 90 degrees

To cut straight across a round pipeline or a rectangular metal profile, use a sheet of plain paper. They wrap the workpiece in such a way that the edges of the paper sheet coincide, after which it is fixed on the part with tape or glue. an angle grinder is held next to the edge of the paper sheet with a thin line, after which it is gradually deepened until it is completely cut.

A metal profile or a round pipe can be cut using a template, putting on them an evenly cut element with a large inner diameter.

Paper mold for pipe

One of the most common ways to make a pattern for pipes with a round surface is a method for which you will need a lined sheet of paper, a ruler and a pencil. To obtain a paper pattern, proceed as follows:

  • Draw a circle on a piece of paper with the diameter of the pipe to be cut, break the circle into 16 equal segments, each time dividing large segments into two equal.
  • Measure the circumference by multiplying its diameter by the number Pi, equal to 3.14. Lay this size on both sides of the axis of the circle in equal segments, each of which is divided into 8 equal parts.
  • Draw from segments on a straight line vertical mowing line up and horizontal from the points set on the circle.
  • The places of their intersection are connected with a smooth line and, as a result, a template applied to the paper is obtained, which is cut out and glued to the trimmed surface. For trimming, it is better to use an angle grinder with a small diameter disc. the surface will be curved and when using a large disc, the error will increase.

Techniques for cutting pipes at an angle of circular cross-section

Round pipes of different diameters are cut at an angle when the direction of the pipeline is changed, while it should be borne in mind that a straight cut at the desired angle, unlike a rectangular section, will not lead to a tight joint of the edges. Therefore, special patterns are used, in which the marked edge has a curved shape, which makes it possible to obtain a high density of the connection.

DIY pipe miter box

For this, a previously made template is used, in the side of which a hole is drilled and a nut is welded. When working, a homemade miter box is put on the profile, a bolt is screwed into its nut and the device is pressed against the profile surface. an angle grinder with a disc for metal makes a cut, slightly pressing the disc to the side surface of the device. It is clear that with long-term work, the edges in the miter box are gradually grinded, and although the process occurs simultaneously on all edges, some errors will appear over time. Therefore, it is better to make the device from hard wear-resistant metal in order to increase its service life and obtain a more accurate tool.
