Scissors for cutting polypropylene pipes - why produce a special tool?
Polypropylene by the method of manufacture and physical properties differs little from polyethylene. The main differences are that it is less dense, but more wear-resistant and heat-resistant. It was the last two moments that determined its use as a material for the production of hot and cold water products, as well as for the equipment of heating systems.
Since polypropylene pipes are sold in the form of coils or straight lengths up to 12 meters, it is quite obvious that during the installation process, there is often a need for trimming them to the required length, followed by welding.
For the first operation there is a special tool for cutting polypropylene pipes, welding is done by an inexpensive electrical device that does not require any professional skills on it.
Tool for cutting polypropylene pipes - what will you have to deal with?
One of the significant advantages of polypropylene products in front of metal is their ability to resist fracture during freezing, which is very important in the countryside, where electricity and gas supply failures are quite frequent.
However, in the event of a defect in a certain area, the cutter for polypropylene pipes will allow a few minutes to remove the damaged section and replace it with a new one. That operation, which in the case of using metal pipes would take several hours, in this situation takes about half an hour.
Conventional polypropylene communications are designed for use at temperatures up to 60 degrees. If there is a need to transport liquid up to 95 degrees Celsius, polypropylene reinforced pipes are used, which have on the outside a thin aluminum shell, which serves to prevent their softening and sagging.
For cleaning from the outer sheath before welding, there is a special knife for polypropylene pipes, which removes the aluminum coating exactly to the depth of welding. Some firms have started production of products with internal reinforcement, which do not need preliminary cleaning.
Scissors and pipe cutter for polypropylene pipes
Now that we have briefly become acquainted with this relatively new product in the plumbing market, we will touch upon the issue of cutting polypropylene pipes. According to the principle of operation, all cutting devices can be divided into guillotines and scissors. Scissors, in turn, are also divided into several groups.
The guillotine pipe cutter for polypropylene pipes is designed for cutting pipes from 63 to 350 mm in diameter. Blades covered with Teflon, cut the product at an angle of 90 degrees, leaving a smooth, burr-free cut. If necessary, blades can be easily ground or replaced.
The advantages of this cutting method include the absence of the need for additional surface treatment before welding, as the cut is smooth and smooth, without any deformation.
The guillotine blade mounted on the wheels swings around the fixed pipe in the sector from 30 to 60 degrees, making a cut without breaking and breaking the fibers. After the notch is formed, the blade is immersed into the depth of the whole diameter under the action of the rotating handle-screw and finally cuts the pipe.
Scissors for polypropylene pipes are presented in three groups. Precision scissors with a ratchet mechanism for cutting products from 3 to 42 mm in diameter have a blade with a rack bar, so that the cut takes place without much effort. Simple and easy to use when working with one hand, however, in the case of intense cutting, the hand gets tired quite quickly.
Roller pipe cutters are scissors in which the pipe rotates on the guide rollers, while the other blade presses the cutting roller under pressure. The result is a perfectly flat cut, but the cutting speed is not high enough. A cordless pipe cutter is a scissors with an electric motor. The cut speed is high, and one operation takes from 4 to 7 seconds.
