How to connect the riser pipes and gas pipes of metal

How to connect the riser pipes (preparation)

Qualitative measurements and thorough preparation will be the main engine of job.For pipe diameter is necessary to take care of that for sanitary appliances and vodosoobscheniya should be 5 cm. If the communication is from the toilet, the diameter should be increased to 11 cm. To install still required cast-iron pipes and plastic corners.

At the beginning of the work, the first thing is to do is to replace the riser and connect izdelieiz plastic and cast iron.

liquidation of old cast-iron communications

Removing iron products - a cautious and careful process.You can use a rubber mallet, which, causing precise strikes on cast iron, resulting in the joints product inoperable.Old communications twist in all sorts of sides to remove the tube from the funnel.

If the socket is damaged, it is necessary to use the grinder and cut portion to him.In this case the quality of the connection is provided.Besides grinders can use hacksaw, but it besides labor-intensive and time consuming.New scrap brush away from the old crop residues.you can not break off communication, cast iron, for the reason that even cutting and elsewhere will still be needed.

How to connect the riser pipes made of cast iron and plastic: Connection principle

The main task for the connection is to avoid any kind of temperature effects and mechanical interference.Leakage occurs because of leakage.Temperature "portability" of plastic and cast iron is different, because it is important for the precautionary simply connect them correctly.Infusion of plastic preforms, placed in a cast-iron pipe socket (in the cement mixture) is insufficient because, the plastic will deform and crack the cement.Tightness broken.

Tip: for sealing of plastic and cast iron can be used porous rubber, pre-wound its plastic tube and the remainder by drowning in the socket.

If there is a bell, then docked feasible even the most inexperienced person, but if not, it is possible to use fittings.Namely, the press fittings for metal compounds that are deposited on both sides of the thread for cast iron and plastic.

How to connect the riser pipes using iron bell

Before you start working zagotovte rubber adapters diameter of 5 cm or 11c depending on the size of the blanks.

docking occurs:

1. Cleaning rust old layers of paint and dirt.
2. sealant application on the rubber adapter.
3. Drowning adapter in a cast-iron bell to the end.
4. room adapter to the end of a plastic tube.

product is ready to use, reinstall, cleaning, inspection.

Important!The plastic compound cast iron bell placed with a bias towards the riser.

Installation Flare

For this installation requires smooth cuts of the edges of the pipes and the installation process takes place in two stages:

1. surface is cleaned and treated at her place the rubber sealing adapter.Then put the plastic adapter.
2. This plastic pipe enters the plastic adapter and the product is ready for use.

whole construction disassembled only thing to match diameters.

If the connection did not work sufficiently dense, it is possible to apply silicone sealant, which fill all the leaking hole.

The video shows how you can still connect the communication

proposed above connection options you can try to gas pipes and PVC.For pipe cutter will need, which will be applied to the threads of iron.Flare when it does not, however, as the thread.Therefore, it is cut, pre-lubricated with special grease.

executed thread wrapped tow and her wind the press-fitting and screw it without a key.Wrench can spoil everything, damaging the fitting and the pipe kinks.

As it turned out, the procedure for replacing the pipeline communications and docking is not a difficult job, but it requires your accuracy and compliance with regulations.
