To create modern sewer communications are widely used pvc pipes and sewer fittings, which are the main components of the sewer pipeline. This applies to both internal and external communication. Sewer elements made of polymeric materials make it possible to solve many of the difficulties that arise in the process of sewerage. Polymeric materials increase the performance of engineering networks, and also make their construction more affordable.
Where are fittings used?
Sewer fittings are needed to create a single system of various sewer pipes, as well as to connect plumbing to the sewer.
Most often, fittings and PVC pipes are used for internal sewerage of household systems, namely:
- to divert permanent sewage with a temperature not exceeding 80 ° C;
- to divert short-term drains with a temperature of 95 ° C;
- to divert chemical waste, at a pH level of 2 to 12, depending on whether the environment is acidic or alkaline.
Depending on the field of application, fittings are conditionally divided:
- for use in the internal system;
- for use in an external system.
Depending on the type of connection, fittings and PVC pipes are:
- using a rubber ring;
- bonding without the use of a sealing ring.
What types of fittings are there
Fittings that have rubber o-rings and are used for installation of external or internal sewage systems are of the following types:
- coupling - a fitting is used to connect two segments, the dimensions of which can be either different or the same, to obtain one straight pipe section;
- reduction - is an adapter, thanks to which it is possible to connect pipes with different diameters, as well as pipes made of different materials;
- revision is a part of the pipeline that is used to clean it from pollution;
- tee (dimensions at 45, 67, 90 degrees) - fittings for branching from the main pipe line to the required degree;
- branch - used to create a turn in the pipeline;
- cross (one- or two-plane at 45 or 90 degrees) - is used if you need to create a complex connecting node of the sewerage system;
- non-return valve - needed to exclude the possibility of reverse movement of effluents through the pipeline if a breakdown occurs;
- plug - needed in order to block the pipe if necessary.
In the case of installation of the sewerage system with adhesive, the same fittings are used, but without rubber seals.
Fitting Benefits
The main advantages of PVC fittings and pipes:
- Wide choose. Now many options for sewer fittings are being produced, which makes it possible to quickly mount even the most complex sewer system. In terms of length and diameter, the choice is also quite wide, which allows the use of PVC sewer parts even in places with limited access. Modern PVC pipes and fittings make it possible to hermetically connect almost all types of pipes.
- The lightness of the product. This factor is of great importance, because the system will be much easier to deliver to the installation site and install.
- Ease of installation. In order to mount sewer communication, welding is not required. Shaped parts are assembled easily by hand. Installation can be carried out even by a person who does not have special training.
- Long service life. The average service life of components for the sewer system is 30-50 years.This is due to the fact that PVC fittings are not susceptible to the negative effects of sunlight, high humidity, sudden temperature changes, corrosion, and aggressive environments. The section does not grow completely.
- Affordable cost. Due to its low cost, the popularity of PVC fittings and pipes surpasses other materials.
Mounting Tips
The simple guidelines below will help you arrangement of the sewer system:
- To cut PVC fittings for sewerage, it is better to take a file with the smallest teeth, which minimizes the number of scuffs at the saw cut.
- The edge of the saw cut after cutting must be processed. This will make it possible to avoid gaps in the future, to ensure that the shaped parts are connected as tightly as possible.
- Shaped parts must be cleaned and glued dry.
- If voids are found in the place where the shaped parts are interconnected, they should be sealed using a brush.
If the pipes and fittings were installed according to the rules, the finished sewer system will last the period guaranteed by the manufacturer.
