What Is a Pipe Vise?
A pipe vise is a plumbing tool used to firmly hold and secure a pipe or tube during cutting or threading operations.
It is usually fastened to a workbench, construction vehicle, or tripod work platform.
A vise-type pipe vise is used by clamping a pipe by turning a V-groove-shaped metal fitting with jagged teeth using a screw-type handle so that the metal fitting bites into the pipe and prevents it from slipping.
A chain-type pipe vise is used by wrapping a roller chain around the pipe instead of V-groove tooth metal fittings to fix the pipe.
Uses of Pipe Vises
Pipe vises are specialized tools for fixing pipes during pipe processing, and their use is limited.
They are used for preventing and fixing material misalignment during pipe cutting and welding, and for fixing pipes when incorporating threaded fittings. When processing long pipes, the pipe vises should be used to support the portion of the pipe that is not secured by the pipe vises.
Due to its small size and portability, it is used at construction sites, in unspecified work areas in factories, and other sites where a large number of pipes are handled. Recently, with the development of electric pipe cutters and threading machines, there are more and more situations where work can be done without using pipe vises.
How to Select Pipe Vises
The following points should be considered when selecting pipe vises:
Fixing Method
A vise type generally fixes a pipe with jagged teeth, which may scratch the pipe. To minimize scratching, some vises have finer tooth profiles and can be used for plated (white) or coated copper pipes.
The chain type provides strong fixation with high torque and pressure. In addition, the flexible chain can be stored compactly, minimizing storage space when not in use.
Applicable Pipe Outer Diameter
Some pipe vises have specific pipe sizes to which they are compatible, and it is necessary to select a compatible model for secure fixation.
Generally, applicable pipe sizes are 1/8B to 6B.
Others
For pipe welding, there are welding pipe vises that fix two pipes to be welded in a straight line and concentricity with a chain, or welding pipe vises that fix a pipe to an elbow, tee, or flange and ensure reliable welding work.
