A joiner's, locksmith tool is something without which no one, even a home workshop, is unthinkable. This tool should be diverse, otherwise it is impossible to solve the whole range of tasks. Knowing everything about the pipe vise, a home or beginner master will greatly simplify his life.
Features and principle of operation
A pipe vise is not too complicated. They have two main blocks: one is responsible for the rigid fixation of the workpiece, and the second - for the ability to move it when necessary. The difference is only due to the fact that this billet is a pipe or part of it.
Note: officially such devices are called prismatic, because they are designed to process any cylindrical parts, and not just pipes in the narrow sense. Sponges in the shape of the letter V provide the maximum contact area with the “cylinders”.
A chain vise is a good fit for pipes. For example, a Super-Ego with a top mount . The device is equipped with a chain length of 0.762 m. It is designed to clamp pipes with a diameter of 6 inches (or up to 0.165 m). The support in the form of a letter V is serrated. Thanks to this, as well as the well thought-out design of the jumper, it is guaranteed to exclude deformation of the workpieces.
making the base of especially strong cast iron;
increased wear resistance of sponges (suitable even for professional loads);
tension with a pressure bolt;
upper mount in the form of the letter H.
It is quite difficult to find a pneumatic vice for pipes, moreover, such models are not found in the most extensive catalogs. But desktop models are easy to buy.
For example, Partner with the largest diameter of 63 mm. Model PA-1108-25 is claimed to be suitable for machining pipes with diameters up to 68 mm. The device is made in China, at one of the leading enterprises in the industry.
Good and folding vice Stayer 3262-2 . The model has a size of 3.5 inches. First-class cast iron is used to make the vice. The product meets the highest strength requirements that are characteristic of developed industrial production.
Newton 3-inch bench vice is also suitable for pipe work. It is possible to fix workpieces with sizes from 10 to 89 mm in them. The device is positioned as an excellent assistant for professionals focused on the highest practical result. The device can also be used to process a metal rod.
The folding top allows you to quickly set the workpiece in the most rational way.
You can also note:
reliability of fixation;
stability of the special holding hook, its long service life;
corrugated jaws, eliminating the rotation of the workpieces;
the surface of the base, due to which the stability of the entire tool and the workbench under it increases.
A nice alternative may be the SPARTA 185705 vice . The mass of the model is 4.5 kg. The sponges open 89 mm. The frame is made of selected steel. The vice is made according to the folding scheme and is firmly held in place by means of bolts.
The Bison 32611-2 deserves attention. With a total weight of 3 kg in a package, the product opens 90 mm sponges. The frame, as in the previous case, is made of good steel. The vice fully complies with GOST 1977. Other parameters:
RIDGID BC210 40185 vice is also suitable for working with pipes . Their net weight is 3 kg (in the package 3.3 kg). Sponges open 60 mm. Good-quality cast iron is used for the manufacture of the frame. There is even a special version for working with plastic pipes.
How to choose?
Familiarity with the descriptions from the manufacturers themselves shows how important the working diameter is. It is he who determines the size of the pipes that can be clamped in a vice. No less important is the strength of the main structural material and the stability of the product . The last two parameters need to be clarified not only by company descriptions, but also by reviews, because in reality promises are not always realized.
Another important subtlety - the device that is hung on the pipe itself for welding should not be unnecessarily “weighty”, otherwise problems will arise.
When you get acquainted with the reviews, you should visit several independent sites at once. What is important, it is impractical to use models on a wooden base for working with pipes. Steel and cast iron are the only two justifiable options. Steel products are lighter, but cast iron structures are stronger. The choice must be made depending on what will be the priority. Locksmith models are designed to hold solid workpieces, without affecting their strength, but completely eliminating any way out of control.
Machine tube vices are mainly used in workshops. Such equipment is absolutely not intended for constant movement, and it is very expensive. Therefore, it is impossible to recommend it for plumbing work at facilities. There it is more correct to use a manual vice, which is placed on a workbench, or special devices installed on the pipes themselves being connected.
The larger the stroke, the more versatile the device.
