Pipe fabrication is crucial as it is one of the steps of pipe preparation before they can be welded together. Although it may seem simple, pipe beveling is quite an important step that can impact the quality of the welds. Due to this, you can experience the entire strength of a structure you might be fabricating. No matter the material used, steel pipe, carbon steel, or others, it must be beveled for excellent connections that can be withstood.
In this blog, you will learn why pipe beveling is important, what benefits it provides, and what angles and tools we will need to have for the job.
Why is pipe beveling important?
Pipe beveling creates an angle or bevel at the end of the pipe or tube. The edge of the pipe is machined at a certain angle, which will depend on the type of joint you will use it for. The angle created is usually to prepare the pipe for welding and ensure that the weld forms a strong, clean, and smooth joint.
But it is not just about aesthetic appearance or convenience. It is about ensuring that when pipes get welded, they are formulating a secure and efficient connection. This is a more important case in industries such as construction, oil and gas, or manufacturing, where strength in welded joints can be highly critical.
It’s not merely a mechanical process, but the pipe beveling also forms the foundation of a solid, strong weld. Here are a few reasons why pipe beveling is crucial for welding.
Improve welding quality
Beveling a pipe serves the main purpose of producing a quality weld. This means creating a groove or space when the two pipes meet, which allows the melted metal to flow between the ends for stronger bonding.
Improving quality weld
Without beveling, the weld could not penetrate well enough and, therefore, it would lead to weaker joints. It may result in leakage, stress fractures, and, in more critical conditions, system failures. The clean and precise bevel pipe establishes the perfect setting for a welder to make a solid, full-strength bond.
Promote Traditional Assembly
In traditional pipe welding, beveling tools are usually required to make sure that the pipes align and connect smoothly and precisely. When a bevelled pipe end meets another bevelled edge, then two such surfaces will perfectly mate with each other. This alignment tends to hasten the welding process since less time is spent adjusting the pipes upon assembly.
Bevel pipe ends meet each other. Thus, welds are much easier. The whole process of your assembly is supplemented with efficiency and uniformity.
Improve construction efficiency
The construction process can be greatly fastened by using beveling pipes. The easy joining of the beveled pipes during the welding process lets you avoid the unnecessary, time-consuming, and hassle of correcting the wrongly aligned pipes.
It also reduces the likelihood of rework and time delays at a cost. The more precise you make it to bevel, the fewer problems you will have later on; it directly leads to improving your projects’ efficiency.
Adapt To Different Application Requirements
Not all welding applications are created equal. Some welds may demand a V-type angle for deeper penetration, while others need a J-type bevel for greater material utilization. Pipe shades ensure proper tailoring of your welds to meet your application’s demands by permitting the beveling of pipes to various angles and types.
Important factors in bevel processing
Beveling pipes entail a number of factors that you should consider so that the slopes are cut correctly and consistently. Let us discuss some of the main issues affecting beveling:
- Accuracy of the Angle: It is crucial to apply the slope angle. Whether it is a 37.5-degree bevel or more specific in details, you must fall within the tolerance level for a strong weld.
- Bevel Length: The other is the length of the slope, which is the cutting area of the pipe that cuts at the angle. Uniformity in bevel lengths in all the pipe welds will make welding easier and help ensure equal joint strength.
- Bevel Surface Finish: The bevel surface should be smooth in such a way that there is no rough edge that can influence the weld. Deburring and finishing the bevels after cutting may enhance the outcome.
- Machine Speed: The speed of your beveling machine can affect efficiency. More work done in less time means fast cutting, but you must ensure that speed does not compromise precision.
Types of Bevels
There are quite a number of bevel types you can use depending on your welding needs. Let’s take a look at the most common ones:
V-Type Bevel
The most common method of beveling is by applying a V-type bevel. The pipe edges are beveled at a uniform angle, and when two beveled pipes join, they form a “V” shape. This kind of angle is applied when you want deep weld penetration for strength.
U-Type Bevel
A U-type angle is somewhat of a less desirable option but does the trick well enough when it is needed in the process. The shape of this angle is like a “U,” which makes it a smooth, rounded surface that is welded to fill in. This bevel is used where less welding material is required.
J-Type Bevel
A J-type angle has a more curved profile. It makes the weld metal distribution more even with less material to fill the gap. It minimizes heat affecting the zone, which might be useful in preventing warping or distortion.
Equipment for Bevel Processing
You will need the correct equipment to get the best out of your pipe beveling process. These are the most common tools used for beveling pipes:
Hand Hand-held bevel Machine
Small to medium-sized projects are best performed with handheld beveling machines. The handheld beveling machines are light in weight, portable and easy to use. They can be obtained at a reasonable cost. It is also appropriate for beveling pipes in minimal and confined spots or even on-site promptly and accurately.
Fixed Bevel Machine
A stationary beveling machine is also required for large-scale operations. These machines are stationary, built to produce high-volume angles and very precise bevels, and can also accept a wider range of pipe sizes and thicknesses.
Plasma Cutting Machine
Plasma-cutting machines may also be used to bevel pipes. A plasma jet cuts through metal at a very high temperature, making these machines ideal for cutting thick pipes and, therefore, giving a clean edge.
Laser Cutting Machine
These laser-cutting machines are highly precise and can achieve very thin angles. Working on the principle of laser, these machines melt the edges of the pipes and, hence, produce clean and precise angles with low heating and distortion.
CNC Milling Machine
These CNC milling machines are used to carry out highly precise bevel cutting, mostly in a controlled workshop. These can develop bevels in pipes of all sizes and are suitable for large-scale fabrication works.
How To Getting Perfect Bevel-cutting
Perfection in bevel cutting can be achieved only if the approach and the equipment are right. Here are a few tips to get there.
Choose the Right Bevel Type
Before perfect beveling, you have to choose the correct type. You will determine the type of weld you’re doing and the pipe thickness. A V-type angle is good for deep welds, whereas a J-type slope may be more useful for shallow joints with little amount of heat distortion.
Bevel with the Right Bevel Tool
Once you select any particular type of angle, you must use the appropriate type of beveling tool based on the material of the pipe as well as the shape of the angle that you wish to get.
