How to cook polypropylene pipes

Priority of processes for connecting pipes

Connection of propylene pipes is carried out in the following sequence:

1. Readiness of a special soldering iron( attachment of nozzles, heating to 260 C) and preparation of welded units for welding.
2. Laying pipes and connections into the unit.
3. Securing the parts to be bonded until the molten layers of the pipe end and fitting have been cured.

Undoubtedly, when you start the welding process, there will be a lot of questions and complexities. But then we'll pay attention to a few common mistakes and reveal the secrets used by experienced masters during the installation.

Preparing for assembling and soldering

Before you can make polypropylene pipes, you should prepare for welding. To do this, you need to stock up on all the necessary tools. Before welding, all equipment is tested for readiness for production, integrity and operability.

Special tools required:

• Device for connecting polymer pipes with a set of nozzles;
• Cutter;Pencil, tape measure.

Welding instructions for polypropylene pipes

Stage 1: preparatory work for

Before starting welding, it is necessary to prepare a "battlefield": dismantle the old system, clear the place of installation, install a stop valve and, in fact, prepare the pipes themselves. First, using a pipe cutter, the length of the desired length is cut off, the hole made is calibrated, the chamfer is removed from the outside of the surface.

Stage 2: Preparation of welding equipment

The welding device is installed on the work surface and securely fixed. Then two nozzles are attached to a special metal tire: a tube nozzle( with a hole) and a coupling( with a rod).After this is done, the device is connected to the mains and heated to 260 degrees. It is considered ready for use when the corresponding light sensor lights up.

Stage 3:

Welding Technology Before using the machine, it is necessary to calculate the warm-up time of the parts used. The calculation is performed taking into account the tabular data taking into account the diameter of the welded components and the time of their heating. The table can be found in the set of accessories of each soldering device.

How to cook polypropylene pipes correctly?

1. The coupling is mounted on the nozzle-rod, and the pipe - into the niche of the second nozzle. The heating begins, the stroidetals must contact the elements of the soldering iron for 6 to 10 seconds, depending on the diameter of the nozzles.
2. When the previous operation is completed, it is necessary to lay the pipe in the fitting. This action is carried out by one movement, without rotation of the elements of the node. With the help of a pencil, the depth of the crimping of two parts is pre-marked. The unification of the molecular structures of the ends of the elements will take place in 5-10 seconds. Minimal fixation and retention of the welded assembly occurs within 10-15 seconds.
3. The final stage is the curing of the welded joint for 2-3 minutes. It is recommended to postpone the finished node and not to change the mutual placement of its parts in each other.

Polymer pipes are one of the most convenient, designed for the construction of water supply and heating networks because of their high temperature stability, unique anti-corrosion, thermal and mechanical properties.

They are convenient because of their simple and does not require special professional skills of installation. Almost everyone can learn how to cook polypropylene pipes and try to do it yourself.
