Pipe or tube cutting is an essential procedure in the fabrication of metal. Pipes and tubes are made of several materials. Every material demands a different cutting technique and equipment. Let’s learn more about the various tools and methods of tube and pipe cutting.
What are the various techniques used to cut pipes and tubes?
- Abrasive Cutting
- Band Saw Cutting
- Cold Saw Cutting
- Laser Cutting
- Shearing
- Lathe Cutting
What are the guidelines that need to be followed while selecting a process and tools for fabrication?
- Ensuring the quality and alignment of the blades are appropriate.
- Considering the reaction of the metal towards friction and temperatures during cutting.
- Buying protective equipment and accessories along with cutting tools.
- Lubrication for the tools is required so that heat generation during the cutting process is under control.
Let’s learn about the various cutting techniques in brief:
- Abrasive cutting technique:
An abrasive saw is used to carry out this process. It is the most suitable method for metal pipes and tubes. A rotary abrasive saw is used to cut through the metal using shear forces and friction
- Band Saw Technique:
The Band Saw is an electronic tool with a seamless blade and contour tooth. The seamless blades move vertically over two mounting wheels whereas the tooth contours rub against the pipe.
- Cold Saw Cutting Technique:
This technique involves a rotating cold saw. The cold saw is kept at a fixed position and the blades rotate. The material to be cut comes directly in contact with the saw. It is highly recommended for perpendicular cutting. This is a highly used and popular technique as it generates no heat and leaves zero heat-affected spots on the surface that have been cut.
- Laser Cutting technique:
It is known as one of the most efficient and user-friendly techniques. It is carried out using CNC machines operated using numeric computer controls. It can cut through the plastic as well as metals. It uses a laser beam to cut through the material. It is recommended for cutting shapes and angular cutting due to its accuracy.
- Shearing Technique:
In this method, the material is cut under the sheer force of two ID punches and plates.
- Lathe Cutting Technique:
This is regarded as one of the most effective techniques. It is highly suitable and recommended for thorough and grove cutting. It consists of a spindle that rotates. When the rotating spindle comes in contact with the material of the pipe or tube, the cutting takes place.
