Portable pipe beveling machines are essential tools for beveling operations. It is used to form an angle between the edges of one end of the pipe or a tube. When you successfully form an angle between the edges, it is then referred to as a bevel end or beveled end. Despite welding, beveling pipes are also done for aesthetic and safety reasons.

Well in conclusion you can say that buying a pipe beveling machine is not a decision you can look down upon especially when your business mainly deals with beveling operations. A wrong decision can negatively impact both your business and income. However, you may initially see portable pipe beveling machines as an expensive investment but the resulting benefits will far exceed the investment. It will enhance the bottom line of your workplace by increasing the versatility and flexibility of the workforce. Overall it&#;s a profitable deal for people who dwell in beveling and welding operations.
Despite all the benefits, you must have some doubts or questions in your mind like &#;Why should we bevel pipes only using portable pipe beveling machine?&#;. You may already know that there are several methods to bevel a pipe. They can range from cheap to expensive and choosing the right can become a tiring task.
Other Methods Of Beveling Pipes
To figure out the advantages of using portable machines, we first need to compare them to the typical methods that are being employed in the market for a long time. Excluding portable or stationary beveling machines, you can bevel pipes via hand grinder, or even by utilizing a plasma or torch cutter.
The Hand Grinder:- The hand grinding method of pipe beveling is the cheapest in this list. However, that&#;s the only benefit you will get by employing this method. It&#;s not only dangerous for the workers to employ this method but it&#;s also highly unproductive. This method is time-consuming and it can only be performed by s a skilled operator. Moreover, you will see a difference in bevel quality in each pipe by using a hand grinder.
Torch Or Plasma Cutter:- By using a torch or plasma cutter you can also bevel pipes and unlike a hand grinder it&#;s a time-efficient method. When compared to a typical hand grinder it shows faster results but it also has some serious drawbacks. Despite being faster it puts your hand at risk of being critically injured and on top of that, the quality of products would still be inconsistent.
Top 10 Uses/Perks Of Portable Pipe Beveling Machine
Grinding abrasives require the right guidance about how to store, test, and use them; otherwise, a routine grinding application can turn into a safety nightmare. Sparks, airborne debris, and a disengaged, detached wheel can all present safety hazards to you and those around you. Improper use also can cause the grinding wheel to break, which can result in operator injury.
No matter how much times passes or how much technology evolves, you still need to do your research to ensure your shop is following all appropriate safe grinding and finishing practices and procedures.
Here are the answers to the top five most frequently asked safety-related questions.
Resin-bonded wheels, including portable wheels, should be used within two years from the date of manufacture. This assumes you&#;ve stored the wheels according to the manufacturer&#;s recommendations. While it may be possible to use resin-bonded wheels after the two-year mark when they are stored properly, you should always examine any wheels more than two years old. Consider having older wheels inspected or speed-tested to determine if any degradation is present.

To help improve shelf life, store wheels in a dry, protected area free from extreme variations in temperature and far away from solvents. Establish a storage system that encourages you to use your oldest wheels first. And never leave a wheel attached to a tool overnight.
Experienced operators know that a safe grinding operation begins long before the machine is turned on. Before you ever mount a wheel, you must give it a visual inspection and put it through a ring test to ensure that it is not damaged.
OSHA, ANSI, and most grinding wheel manufacturers require ring testing before the wheel is mounted on a grinding machine. Vibration is the key to the ring test. When the wheel is struck, it vibrates at a certain frequency and emits a sound, much like a tuning fork. Any nonuniformity in the wheel will change the vibrational response and, consequently, the sound. When the nonuniformity is a structural flaw, like a crack, the ring test will produce a dull sound, alerting the operator to a problem.
However, some wheels cannot be ring-tested because of their size or construction.
Resin-bonded wheels are difficult to ring-test because of their natural vibration-dampening characteristics. When struck, this wheel does not produce a clear tone like vitrified wheels do, making it hard to discern if it&#;s cracked. It takes a quiet environment and a well-trained ear to ring-test a resin-bonded wheel properly. Further, resin-bonded wheels that contain fiberglass reinforcement cannot be ring-tested as they will never produce a clear ring. Portable wheels for angle grinders fall into this category.
Grinding wheels are designed to be operated at certain speeds. Exceeding recommended speeds can cause wheel breakage, risking injury to you and others nearby. So be sure to check the wheel and machine's rated speed every time you mount or remount a wheel to make sure it isn&#;t operating in an overspeed condition.
The abrasive wheel's maximum operating speed is marked on the wheel, and the machine's normal operating speed is marked on the machine. Never exceed the wheel's maximum operating speed as stated in revolutions per minute or in surface feet per minute. Failure to comply with this requirement is not only very dangerous, it is a violation of ANSI safety requirements and OHSA law.
The orientation of the flanges plays a key role in mounting cutting and grinding wheels. The back flange is keyed to the machine so it can go on only one way. With most angle grinders, the outer flange can be used either way, but it depends on the wheel thickness.
For thin cutoff wheels, the recess side of the outer flange should be against the wheel. This allows the flange assembly to be tightened to the point where it holds the wheel, preventing slippage. For thick grinding wheels, however, the hub side of the outer flange should be against the wheel. This configuration allows you to tighten the flange assembly to hold the wheel properly.
The idea that coated abrasives do not require guards is simply not true. ANSI B7.7, Safety Requirements for Abrading Materials with Coated Abrasive Systems, states: &#;If the machine is designed and equipped with guards, it shall not be operated without the guards properly installed and in place. Safety guards shall be properly installed and in place on any machine used in grinding. Guards prevent operator exposure to the drive mechanism and the moving coated abrasive product, help contain grinding swarf and any flying debris in case of breakage, and are often part of the dust collection system.&#;
When operating a right-angle grinder, you must have the guard in place. When using a portable sander, a guard is optional unless the tool was originally equipped with one. Never remove a guard provided by the machine manufacturer for any reason. It is there to keep you safe.
