Chamfering tool for plastic pipes

Steel

Cleaning before painting is designed to maximize paint adhesion to the substrate. Painting over rust (especially plastic) ensures that the decorative anti-corrosion coating detaches in the shortest possible time. An alternative to scraping is the use of rust converters phosphating compositions, which transform iron oxides into a strong and chemically resistant film, directly on which paints can be applied.

Agree that to paint the profiled tube in such condition without cleaning is not a good idea.

The threading entry allows the first threads to be chamfered with minimum clamping force by the die or cleaver. The greater the chamfer angle, the harder you have to press the die against the end of the pipe. If there is no chamfer the tool even with maximum pressure will not go to the pipe or the first thread will tear off over and over again.

Polypropylene

Why do you need stripping for reinforced polypropylene pipes?

Polypropylene has two problems associated with its operation in hot water and heating systems.

  • When heated, the tensile strength of the pipe decreases. If at 20 pipes PN 20 is capable of withstanding the hydraulic pressure of 20 kgf/cm2, when heated to the maximum for her 95C allowable pressure decreases to 7.9 atmospheres. No wonder: Polypropylene is a typical thermoplastic with all the consequences it implies;
  • Polymer has a very high (even compared to other plastics) coefficient of linear expansion when heated. If you raise the temperature of the pipe by 50 degrees, each meter of it will lengthen by 6.5 millimeters.

Both problems are successfully solved by reinforcement.

Reinforced polypropylene is used in heating systems.

It can be done in two ways:

  • By adding chopped glass or basalt fibers to the polymer melt. The middle reinforcement layer of the pipe is already fused with the unreinforced layers of pure polymer during the extrusion process;
  • By sandwiching between two layers of polypropylene a layer of aluminium foil approximately 0.5 mm thick. The quality of an aluminum-reinforced pipe strongly depends on the manufacturing technology and the glue used in the process.

The type of reinforcement can easily be determined by looking at the shear layers.

Typical operating pressure of reinforced pipes is 25 atmospheres (this is indicated by the designation PN 25 in the marking). When heated it is reduced to 10 12 kgf/cm2. Elongation when heated also appreciably decreases:

chamfering, tool, plastic, pipes
Material Elongation of one linear meter of pipe when heated at 50 C
PPR without reinforcement 6.5 mm
PPR with fiber reinforcement 3.1 mm
PPR with aluminum foil reinforcement 1,5 mm

Steel pipe elongates by 0.5 to 0.55 mm under similar conditions.

For obvious reasons, foil-reinforced pipes are most in demand in heating and hot water supply. However, an unpleasant surprise awaits the lucky buyer: aluminum forms a galvanic pair with copper and steel, which are often present in heating and DHW circuits.

The small thickness of the foil causes it to deteriorate due to electrochemical corrosion upon contact with water in just 2 to 3 seasons. As a result of its destruction, the pipe at the end, inside the socket fitting, begins to delaminate, with the accompanying process of catastrophic loss of wall strength. A relatively weak water hammer or noticeable heating ends the career of such a pipeline prematurely.

The mechanism of tube destruction without stripping.

The obvious solution to this problem is to remove the aluminum reinforcing layer from the welding area. Stripping of polypropylene pipes is the preparation of the end of the pipe for soldering with a fitting, which boils down to cutting foil from the surface of the pipe (in the external reinforcement) or between two layers of polypropylene (in the internal).

What tool is needed for polypropylene pipes and how to use it during installation

Installation of various pipes or other products always requires an appropriate set of tools, without which most technical work becomes impossible. This also applies to polypropylene pipes, which also require the presence of proper equipment to work with.

Valtec metal pipe calibrator with 16-20-26 mm bevel knives VTm.396.0.162026

Calibrator for pipes with Valtec VTm chamfer knives.396 is a necessary accessory for the mating of polypropylene utilities. The tool is used by professional fitters to prepare polypropylene, polyethylene and metal plastic pipes before planting them in special fittings.

The tool body is equipped with three kinds of calibrating elements, positioned from each other at an angle of 120 degrees. product material. polypropylene. Chamfering blades made of high-strength, laser-ground steel blade.

Important design difference. collapsible body. The calibrator is disassembled for sharpening the chamfering knives.

To correctly use one of the three chamfering blade options, the body is identified by a numerical label that indicates the pipe outer diameter.

Advantages and distinctive features

Speed of calibration. Important feature when preparing a large number of pipes, which reduces the overall time of delivery.

Three chamfering blades with different calibers in one housing. So, there is no need for the machine operator to carry a whole set of the appropriate tools.

Tool separability. The installer can inspect or resharpen the chamfering steel blades. This feature saves money on buying a new tool.

Ease of use. Not only a beginner, but also a do-it-yourselfer can get the hang of the calibrator.

Manufactured by Italian company Valtec. The tool has two modifications in the catalog, based on pipe diameter:
