Pipe vice

Types of Pipe Vices

A pipe vice is a critical piece of equipment that restrains pipes while cutting, squeezing, welding, or threading them. Generally speaking, pipe vices come in three core types based on their design and functionality.

• Floor-stand Vices

A floor-machine shop vice is bolted to the floor for added machined parts in bigger sizes. It's called a bench vice because it's anchored to the workbench. It's got an underbite jaw that grips objects from below and another jaw from above. Elongated vertically, this jaw makes it easier to grip irregularly shaped items. Pipeline machinists use this type of fixture for bigger operations where more machining is necessary. They also use it where complex shapes need to be held tight.

• Portable Vices

A portable vice is a hand-operated device used to join pieces of metal. It usually comes with a two-piece cast iron body, one of which is fixed, while the other is moved up to hold the workpiece. Some have human-powered crank handles, while others are motorized. Motorized versions have a rapid screw thread that makes them faster to operate than manually run portable vices. Because they're manually operated, human-powered portable vices operate at slower speeds, making them unsuitable for machining metal parts. They're mostly used in pipelines to hold irregularly shaped objects under normal working conditions.

• Locking Vices

This is a heavyweight vice that has jaws up to 12 wide. It secures objects with parallel jaws that slide together. It's permanently fixed to the worktable and clamped down with a large lever. The locking mechanism on this vice releases the object anytime after work is done or when there's an emergency. It doesn't require any adjustments to lock objects tightly, making it one of the most user-friendly pipeline vices. Locking vices come in various sizes, including small to extra-large to fit all objects. They also have different throat depths, ranging from shallow ones measuring one to two inches to deep ones measuring up to six inches. Large sizes are used on big-diameter pipes, while smaller ones are used on small diameters.

Specifications and maintenance of pipe vices

Specifications

• Sizes: A pipe vice is manufactured in different sizes to cater to multiple piping needs. On average, most pipe vices can hold pipes with diameters of up to 12 inches (30cm) or more.
• Material: The most common material in constructing a pipe vice is cast iron because of its strength and ability to withstand external pressures. However, some heavy-duty pipe vices are made of steel to provide extra strength when dealing with huge pipes.
• Weight: The weight of a pipe vice translates to its durability and strength when dealing with heavy pipes. On average, a 4-inch pipe vice weighs around 10 pounds (4.5kg), while a 12-inch heavy-duty machine can weigh up to 90 pounds (about 40kg).
• Design: The jaws of a pipe vice are designed to hold irregularly shaped objects tightly. The jaw plates are padded with rubber to prevent damage to the object being held.

Maintenance

Maintenance of a pipe vise involves frequent cleaning to prevent clogging and damage to crucial components. The cleaning process can be conducted in several ways, including steam cleaning or hot water and detergent cleaning.

• Steam cleaning: It is the most effective method of cleaning a pipe vice. Operators are advised to expose the vice to a steady stream of clean water for about five minutes. The clinic process initiates the automatic self-cleaning process of the machine. After a few minutes, operators can use a pipe wrench to assist in clearing any remaining clogs.
• Hot water and detergent method: It is an alternative method to pipe vice cleaning in some instances. The method entails submerging the machine in hot soapy water. The technique provides a more profound cleaning experience in all corners and hidden areas of the machine. After cleaning, the technician can turn the machine on to remove excess water from the interior part.

Regardless of the dominant cleaning method, operators must ensure all electrical components are dry before switching on electricity.

Occasional cleaning of the vice head is also necessary at least once every six months. Use a wire brush to get rid of dirt and debris from the machine. If necessary, use lubricant oil to remove excess dirt and debris and maintain the smooth operation of the machine.

Scenarios of using pipe vices

Users can employ different types of pipe vices in several usage scenarios. The primary use of a pipe vice is to provide a holding platform and support for pipes and irregularly shaped workpieces during cutting, threading, welding, and other operations.

Fitters and car mechanics use the jaw design and size of the pipe vice to hold irregularly shaped objects firmly while they perform various operations. In plumbing and welding workshops, the pipe vice is an essential tool for holding pipes during threading or cutting operations. This enhances precision during the operation.

Both professional woodworkers and DIY enthusiasts use a bench pipe vice on their workbench to hold irregularly shaped workpieces and pipes firmly in place during gluing, drilling, and cutting. This makes the work easier and enhances precision.

In the metalworking industry, a machinist uses a bench-sitting or stand-mounted pipe vice to hold pipes and other irregularly shaped metal objects firmly while cutting, welding, or threading. Some machinists also use an automatic pipe vice when working with high volumes of workpieces that require piping.

How to choose pipe vices

Both the tool's strength and longevity are greatly influenced by how well it is maintained. In addition to figuring out how to choose a pipe vice for others, think about the maintenance requirements for the equipment.

• Regular lubrication:

Lubrication on a regular basis is required for pipe vices to function properly. Users can keep the machinery in good shape and working for a long time by regularly applying grease or oil to its moving parts. The routine maintenance needed for the equipment should be considered when selecting a pipe vice for use by numerous people.

• Simple cleaning:

Cleaning should be simple, allowing users to wipe off any dirt or grease with only a damp towel. It's crucial that people can maintain good hygiene with minimal effort because several people might use the equipment.

• Replacement parts:

To keep the machine operating properly and in good condition, consider how simple it will be to obtain replacement parts. Users will find it simple to replace worn-out components, extending the equipment's life and usefulness to a large population of users.

• Durable materials:

The durable materials used in construction will last for many years, even under constant use by a large number of users. Selecting an item constructed from robust materials will help ensure that it is still functional and useful after years of heavy use by numerous individuals.

Think about the things that may be done to protect the vice from damage. Users should take precautions against accidental damage and keep it in good condition for their continued use. On this occasion, paying close attention to how securely fastened the clamps are is a wise choice.

Even with regular use, they will hold on tightly to the pipes and won't let go. They won't break easily, so a lot of people can use them over the years without them getting broken or worn out quickly.
