Types of sewer pipes and their connections

Types of plumbing pipes and their features

Today's market of sanitary products are literally overflowing with various materials.Are no exception and sewer pipes, which are:

• Plastic - the most popular.They are made of polyvinyl chloride, polyethylene or polypropylene.Such products are intended for both internal and for external works and depending on the application features have different diametry- from 32 to 160 mm.
  
  Advantages: Anti-corrosion, damage resistance, ease of installation, reasonable price.
• Ceramic - most often used for the installation of external sewage.The diameter of such tubes is from 150 to 600 mm.
  
  Advantages: resistance to aggressive chemical environments.
• Cast - gradually fading into the past and replaced by lighter and cheaper counterparts.However, they have their advantages - resistance to corrosion and high strength.
• Steel - is used less often because very quickly rust and disintegrate under the influence of groundwater.

Sewer connection

By means of the connection of sewer pipes are two basic types can be distinguished:

• Split;
• -One.

in favor of a way to make the choice will depend on the material characteristics of the pipeline and its location.

Plug connection pipes

Detachable connection method, in turn, further divided into two subspecies:

• Coupling.
• Flange

Coupling type used for the connection and repair of pressure and pressure pipelines made of plastic with a diameter less than 63 mm.The result is a collapsible drain structure that greatly facilitates the, if necessary, its removal and replacement.

compressor or the nut installed in such a way:

• are prepared stud ends: cut off with a sharp knife at right angles and carefully stripped;
• pipe ends and the inner surface of the sleeve are treated with special grease, which later will serve as a sealant;
• By coupling at the same time both sides are attached and clamped joints locknut equipped with a sealing ring;

no less popular for fastening pipes PVC sewer pipe is flanged manner.

It uses iron flanged fittings, which is mounted in the following order:

• pipes are cut at the ends and stripped from the barbs;
• flange is attached to the section of the pipe, with rubber gasket should extend beyond its borders;Thereafter
• flanges mounted on the two joints are joined together by bolts.

permanent connection

Ways permanent connection of pipes, too, there are several types:

• socket;
• Welding;
• adhesive.

socket method is a combination of parts with special thickening at the end - the bell.This method provides an adhesive attachment and welding.

However, before proceeding, you must spend preparing pipes.To this end, their sections are cleaned from dust and dirt, remove possible roughness and burrs, and after - a special lubricated with silicone grease.

What repents welding method to implement it, or butt welded bell and spigot.In the first case, the welding machine is reflowed both pipes simultaneously: the first one - from the outside, and the second - inside the socket.After that, they both connect to each other as soon as possible.

Butt welding involves melting sections of pipes and connecting them with little effort.

Bonding sewer pipes is carried out with a special glue, suitable for the type of pipe.Choose a glue can be in any specialty store or market.

Step-action bonding working surfaces:

• necessary to clean and degrease the surface;
• Then for pipe sections apply the necessary amount of glue;
• Connect segments with each other to fix the complete solidification of glue;

Any of the above methods quite effective in a strict sequence of work and compliance with safety standards.
