Any construction, as well as installation work can not even be imagined without the use of tools. Thanks to TOOLS, you can easily press and crimp the press fittings or mount a pipeline. The only question that the brain buys is: "Is such a tool necessary for the home, for the family?".

Special tool for pipe installation
When installing plumbing and heating systems, a special tool is used to create a reliable press connection.
The press tool is designed for crimping fittings. Crimping of fittings is possible for various pipelines from copper and metal-plastic. The versatility and mechanism of action of the hand press tool allows you to mount any pipeline, even complex configuration, without considerable physical effort. How to choose a press tool for installation work?
What is a press tool?
A press tool means a drive actuating the press pliers and the corresponding systems. There are the following types of press tools:
• manual (radial pliers and press gun)
• with the electric drive.
It is necessary to distinguish between two types of press tools: radial and axial.
For radial press technology, these types of connection are used:
• connection of pipes using a press fitting, mounted on a pipe and fixed with a sealing ring
• connection of pipes with the use of an insert fitting (supporting sleeve), fixed with a sealing ring and fastening.
We will discuss immediately that the press tool has a high price, especially equipped with an electric drive. Therefore, the appropriateness of the acquisition should be due to the continuous use of its application.
Press tools, hand tools
The hand press tool is a radial mite and a press gun, designed for crimping and crimping pipeline systems:
• thin-walled stainless steel pipes
• Metal-polymer
• polymeric
• Copper.
radial pliers
Press tools manual (radial mites) structurally consists of the mechanism of the press head and telescopic handles. The total compression force is dependent and regulated by both the telescopic arms and the presshead mechanism. The mechanism of the press head can produce a rotational force relative to the handles at a full angle.
For the convenience of using a hand press, the valtec tool is equipped with nozzles with a TN profile. The use of a universal profile allows you to install fittings with a diameter of 16, 20, 26 and 32 mm. those. the entire range of the VALTEC press-fitting range.
Any model of manual pressure testing tool is distinguished by the following technical characteristics:
• area of crimping
• the working stroke of the handles
• developed turning force.
Therefore, the choice of radial ticks should be made, focusing on the technical characteristics of the model.
press gun for fittings
The hand-operated manual gun for fittings is designed for crimping and crimping of metal-plastic, copper and stainless pipes. Ergonomic design allows you to produce 100,000 operations for fittings with a diameter of 12-108 mm. To prevent the creation of excessive high pressure, the tool is equipped with a safety valve.
The process of crimping control is automated and implemented using an embedded microprocessor. Therefore, the duration of the compression of the fitting is negligible and amounts to several seconds.
Modern models of a hand press tool with attachments are equipped with a control system that guarantees the quality of each crimp. Such an automatic control system meets the requirements for the types of connections used.
If the crimping procedure does not correspond to the specified parameters, a press tool for metal-plastic pipes will sound a beep. This will mean that the tool must be repeatedly serviced, re-crimped or calibrated. Of course, such a press tool causes genuine delight and respect for advanced technology. However, the acquisition of such an expensive tool is not beneficial in terms of cost.
Press tools with electric drive
The electrohydraulic action of a tool press with an electric drive allows organizing the crimping process in the event that the hand tool is unable to perform it.
The plumbing connections and pipelines obtained in the process of crimping and pressing differ in the following qualities:
• temperature changes in the workflow
• considerable resistance to vibration
• hydraulic shock
• twisting and bending.
The service life of the received connections is considerable and is 50 years, but the price of a press tool with an electric drive is also considerable. The use of a press tool with an electric drive is more justified for industrial enterprises, and not for use in an urban apartment.
Undoubtedly, the development of the production technology of a tool with an electric drive has greatly enriched the tools for installation.
Therefore, such a tool is always multifunctional, thanks to kits and sets of attachments. Removable tool press tools allow crimping of insulated and non-insulated terminals, fittings and sleeves. The range of cross-sections is quite diverse:
• crimping and crimping "oval" up to 6 sq. M.
• crimping "trapezium" with a crimping width of up to 12 mm.
• Crimping by "point" up to 10 sq. M.
• crimping and crimping with "hexagon" up to 6 sq. M.
Replacement of nozzles for the press tool is carried out by special equipment, which is included in the delivery of equipment.
Thus, the most suitable press tool for mounting and reliable pipe connection, can be considered a hand tool. Press fitting and hand tools Valtec will create high-quality and strong connections of engineering systems and pipelines. And in this you will be helped by the design features and high-tech hydraulic characteristics of the press tool.
