How to choose a press pliers for metal-plastic pipes - we analyze the criteria for choosing a tool
For heating and plumbing systems in residential premises, metal-plastic pipes are very often used. This material is reliable, durable, hygienic and has good performance properties. However, reliable operation of the pipeline is possible only if all the connections are completed competently. To do this, you will definitely need a specialized tool - a press pliers for metal-plastic pipes.
What is this tool used for?
Metal-plastic pipes are connected using special fittings, which can be divided into two types:
- Threaded. The use of such a part involves the connection of the pipe by squeezing it with a split ring with a tightening nut. A significant drawback of such a node is the high possibility of an error during installation and the need for subsequent maintenance and control. Since the tightening of the crimping nuts over time can weaken and then leaks appear.
Press fittings.
- Designs, which are a body with a fitting and o-rings, an insulating ring and a compression sleeve. The part is put on the pipe and pressed tightly, providing a reliable connection.
Press fitting can only be installed using a special tool.
Installation of the press fitting is carried out only with the help of a special tool called crimping pliers for plastic pipes.
Experts say that joints made using a press fitting are much more reliable and durable than any other. In particular, press joints:
- allow subsequent pouring into concrete or hidden laying;
- one-piece, respectively, will not require further maintenance and control;
- withstand operating pressure up to 10 bar;
- Assume easy and quick installation;
- guarantee mechanical strength and durability of the joint for at least 50 years.
Criteria for choosing such a device
A modern press tool for plastic pipes has many options. Often on sale you can see expensive electromechanical and hydraulic devices, equipped with a whole range of various clamps. It should be understood that such devices are intended primarily for professionals and it is unlikely that it would be advisable to buy such a device just to change pipes in your own apartment. There is a manual press for plastic pipes, which performs the necessary connections in no way worse than professional devices. In addition, it is very easy to handle, so installing a pipeline with it will not cause much trouble.
Before you go to the store for a tool, you need to determine the diameter of the pipes with which you are supposed to work.Each device is designed for a specific pipe size, and you need to focus on it when buying.
In addition, most often the tool for crimping metal-plastic pipes is equipped with special removable inserts, thanks to which it is possible to work with structures whose diameter is smaller than the maximum pipe size specified in the device certificate. Various instrument models can be equipped with additional optimization and control systems:
- APS - a system that distributes the applied force based on the size of the fitting;
- APC - automatically controls the pressing of the fitting, the press does not open until the crimp is successfully completed;
- OPS is a system that increases the applied forces due to step-type clamps.
Another nuance. The massive counterfeit of materials and equipment that flooded the store shelves makes you be more attentive when buying a pipe clamp press.
Complete with press tongs are usually a few special inserts for working with pipes of smaller diameter
It is best to purchase tools from authorized dealers, if for some reason this is not possible, then do it in a specialized store. Such a purchase will provide a certain guarantee of the operability and effectiveness of the instrument.
Proper crimping of metal-plastic pipes is not such a difficult matter, if you choose the right pliers press. Such work can be done independently, resulting in a reliable, durable and durable pipeline.
