Pipe beveling is an angle forming between the edge of the end of a pipe or tube. When the pipe end is formed with a certain degree of an angle, it is called a bevel end or beveled end. Pipe beveling is an essential step in the welding preparation process of pipe joining. The quality of the beveled pipe directly affects the quality of the welding, so that proper pipe preparation ensures the best possible weld joint. Other than welding, beveling can also be used for deburring the cut pipe ends for aesthetic and safety reasons.
Both beveling and bevelling is correct. Bevelled is the English UK spelling and Beveled is the English US. Also, the wording chamfering and end working are used for this application method.
Pipe chamfering is technically a type of pipe beveling. Both terms refer to an edge between two faces of a pipe or tube. However, the main difference between the two terms is that chamfer is an edge that connects two faces at a 45 degrees angle, whereas the bevel’s slope can be any angle except 45 or 90 degrees.
There are various ways to bevel a pipe. Using portable or stationary beveling machines, doing it by a hand grinder, or by a plasma or torch cutter.
The hand grinding method of beveling is the cheapest and the most dangerous method compared to using a beveling machine. It is time-consuming, and a skilled operator is required to perform a bevel by a hand grinder. Moreover, it is nearly impossible to keep the bevel quality the same for each pipe operation while creating a lot of mess.
Using a torch or plasma cutter is another way of pipe beveling. It provides faster results compared to a hand grinder, however; it also has some drawbacks. The flat land at the end of the pipe needs to prepared by hand, which is not a safe process. Yet again, the produced bevels will be inconsistent.
Also, this method cannot be used on all materials, which would affect your flexibility in production.
A portable beveling machine comes in different configurations and is notably safer than the previous two methods. The biggest advantage of these portable machines is that they are portable so that it’s time-efficient since the user can take the machine to the pipe. They are convenient to use for maintenance work, or on a construction site. However, they are inadequate to meet high production requirements.
Stationary beveling machines provide the most options and flexibility for pipe beveling. Almost all kinds of bevel shapes can be created with different combinations of tools. They are designed to meet high production requirements in a safe working environment. Also, they are easy to integrate with automated production lines, so that the operator does not even have to be on the machine all the time. There are various benefits of stationary beveling machines such as; standard carbide cutting inserts are inexpensive to replace when needed, easy to set up and requires low maintenance, ensures the lowest cost and fastest cycle time per bevel, provides safe working environment without creating a mess, offers a broad range of machining options and can machine several pipe or tube materials, and does not require a skilled operator.
|Hand Grinding||Torch or Plasma Cutter||Portable Beveling Machine||Stationary Beveling Machine|
|Potential safety hazard||Fire hazard||Potential electrical cord hazard||Not suitable for on-site machining|
|Fire hazard||Requires touchups||Possible guarding issues||Relatively high investment cost|
|Creates a lot of mess||Creates a lot of mess||Needs a chip container|
|Time-consuming||Cannot operate on all materials||Expensive custom ground tooling|
|Inconsistent bevel quality||Requires Oxygen or dry compressed air||Time-consuming|
|Expensive grinding wheels||Cannot process J-bevels or special shapes|

Multiple factors need to be considered before choosing the right method for pipe beveling. The following questions would make this decision easier for you:
However, safety always comes first. No matter what the requirements are, assessing all the potential safety hazards on-site is the prior step to decide on the right method.
Copier machinery is specialized in stationary pipe beveling machines and offers a variety of pipe machinery with more than 20 years’ experience within the industry. We are designing, engineering, and manufacturing three different types of beveling machines: Beaver S (with manual and automatic options), Beaver CB (for pipe cutting and beveling, CNC controlled), Beaver CNC, and RTL Series (the most accurate and flexible machining options).
