Tip 1: As welded polypropylene pipes

Pipe welding - a process that requires some skill and equipment.Since polypropylene pipes are welded on a special welding machine on which you install the required diameter nozzle pair.These nozzles have a special coating - Teflon, and to clean them because metal objects can not.Nozzles purified using rags or wooden scraper in a heated state.But enough about the device.Let us turn to welding.
Guide
1
To start pipe cut to size with special scissors strictly at right angles.Set on the welding machine soldering temperature to 260o.Soldering should heat up to the desired temperature for 5-8 minutes.
2
Do not forget to clean the parts before welding.After cleaning, they should be degreased with ethyl, isobutyl or isopropyl alcohol.Gasoline, mineral spirits, acetone and wipe vodka polypropylene pipes is highly undesirable because they loosen the surface.After degreasing check on pipes welded zone.If the pipe is welded, reinforced aluminum, the welding zone with an aluminum layer is necessary
to clean off the welding a special device.Pipes, reinforced fiberglass, do not need to clean up.
3
Then both put pipe and fittings welded nozzle.The duration of heating depends on the diameter of the pipes is determined by special table.When the heating is over, remove the parts from the nozzles, insert them into each other and secure the 3-8 minutes.
4
This method of welding polypropylene pipes provides the highest quality connection and significantly reduces labor costs, and the cost of consumables.It does not require any special skills.
5
If pipes have a small diameter, they are connected by means of welding coupling.In this type of welding two pipes are joined using fittings, elbows or joints.
6
During coupling welding machine must have a temperature of 260o and be included.Heating begins parts evenly.When heated pipes are brought together, the time necessary to survive without deformation and pipe bends.
7
If the items are not heat up to the desired temperature, they will not be so plastic and viscous as necessary.Such a compound would be extremely fragile.When the parts to overheat, polypropylene loses its stability.Insert the pipe into the fitting overheated quite problematic.Increasing efforts, you can fold the edge of the pipe, so that the inner diameter welded tube get less than you need.

Tip 2: How to cook polypropylene

Currently polypropylene gained popularity as a material for the manufacture of pipes.This material is cheaper, pipe it look aesthetically pleasing, it is quite durable and resistant to high temperatures and many chemicals.In mounting it is also not a problem - it is easy to weld polypropylene pipes.
How to cook polypropylene
Guide
1
For welding of polypropylene, you will need a special tool with attachments.It is heated to an average temperature of 260 degrees and thanks to the integrated thermostat maintains a stable temperature.
2
heating elements are the sleeve, which oplavlivaet outer surface of the pipe and the mandrel which oplavlivaet inner surface of the sleeve.It can be purchased at the hardware store, he is not very expensive, but if you need one for a single application, you can rent it from the masters.
3
The welding of pipes with a diameter less than 63 mm are mainly used the socket and grooved method.In this method, the pipe is connected via couplings and threaded nodes are created using flare fittings.For welding large diameter pipes is better to see a specialist, as usual with such vehicles nozzle diameters from 16 mm to 40 mm.
4
Set welding machine on a flat surface and fix it with special keys removable heaters desired size.Install all the necessary attachments to the heating apparatus.For polypropylene need a temperature of about 250-270 degrees.
5
Cut a piece from the pipe size you want, sharpen the edge at a slight angle.If there is an oxidized layer scraped it to prevent deterioration of the welding.Now mark on the pipe length of the connection to the fitting way to end it did not go into the fitting until it stops.Degrease surfaces that undergo welding.Now you can move on to heat.
6
fitting process first, as it is heated long tube.After both the surface reached the desired temperature, remove them and secure smooth movement, but do not rotate.Secure seam until cool.
7
time required to secure the parts depends on the device, usually in written instructions minimum and maximum threshold.
8
must be borne in mind that when heated tube is pulled, maybe even curl.This fact should be considered when planning piping.
