Plumbers frequently need to press pipe and employ a variety of tools to modify and form pipes into different shapes. The purpose of a pipe pressing tool is to apply a high amount of compressive force on the circumference of a cylindrical joint of two pipes to create a liquid-tight connection.
Additionally, both metal and plastic fluid handling systems employ the use of pipe pressing tools. By using such a tool, one can apply a strong force in a short burst across the entire surface area of a circular joint. The joint’s outer diameter subject to the force deforms and results in a crimp joint.
Classification of pipe and hose fitting tools –
Types of pipe fitting tools are:
- Powered tools
- Cross-linked polyurethane PEX tubing tool
- Copper pipe tools
- Tools for speciality fitting
Powered pipe fitting tools may be of multiple varieties. Some employ battery operated electro-hydraulic drive which can also have variable speed advanced triggers. One can use battery powered pipe pressing tools for common tasks like hose fitting, tube fitting, potable water system.
Material and built
The jaws of these pipe and hose pressing tools are generally made of galvanised steel. As a result, they can resist rust and corrosion. Additionally, the presence of galvanised steel helps to prevent copper build-up.
A 360 degree rotating head houses the jaws in a pipe crimping tool. This is to ensure optimal extension and efficiency. Furthermore, a good tool will feature a narrow body to ensure adequate manoeuvrability in cramped spaces. Users should always opt for a tool with universal jaw mount, as this will allow for other standard industrial jaws when required.
Plumbers often need to use varieties of jaws to suit their operating conditions. Hence, it’s advisable that they buy a press toolkit. Also, using proper technique is essential for making a leak-proof and long-lasting joint.
Here is a general step guide on how to join a copper pipe –
-
- Measure and cut the pipe according to your requirement
- Deburr the edges and inside of the pipe near the cut
- Measure the depth of the sockets that require pressing
- Mark on the pipe to indicate the joint depth
- Fit the pipe into the joint. Ensure that it reaches to the depth marked on the pipe
- Choose the right jaw size for the joint and fit it on the pressing tool
- Grip the bead of the fitting with the jaws of the pipe pressing tool
- Keep the tool perpendicular and squared
- Begin crimping and release when complete
Using crimping over other methods of joining
Fitting and connecting pipes through crimping have a certain advantage over other joining methods. A pipe crimping tool is faster than soldering and needs only a few seconds to join two pieces of tubes, regardless of their size.
Moreover, when using these tools, a plumber doesn’t need to carry heavy instruments like solder pastes, flux and other items to the job site. Similarly, using a pipe pressing tool eliminates the need of having a separate power supply. Since press fitting doesn’t need any heat or flame, it’s safer compared to welding.
