Cast iron sewer pipes have a large margin of safety, they undergo significant loads during operation. This makes such products universal, which indicates that they can be used both in private and in industrial construction.
Varieties of cast iron pipes
On sale today you can find pipes made of cast iron for transporting liquids under pressure or without pressure. There is an opportunity to purchase bell-shaped, and also pressure head bell-shaped products.
If you see cast-iron sewer pipes with the abbreviation VChShG, then this indicates that you have high-strength material with spherical graphite. This combination allows you to get pipes that are durable and ductile. During operation, cracks do not appear on them, or rather, the probability of this is very small. If we compare the described cast iron with gray, it can be noted that it has qualities similar to those of carbon steel. Such pipes cope with impacts and demonstrate bending strength, in addition, they are not exposed to corrosion for a long time. You can use them under almost any conditions, since products of this kind are perfectly adaptable.
ChK pressureless pipes
Cast-iron sewer pipes can also be pressureless. If you see the abbreviation CHK, then this indicates that the pipes are made of gray cast iron. In terms of strength, such products are inferior to those described above, therefore they are used where the system will not be subjected to impressive loads.
If there is a need to ensure high-quality fastening, then it is worth purchasing bell-shaped products. They have an extension.
Such pressureless pipes can be mounted in tandem with plastic products. Before starting work, it is necessary to stock up on rubber adapters made in the form of cuffs. Another additional advantage of such pipes is the possibility of their dismantling and use in other areas.
Sewer Pipes SML
Cast iron sewer pipes can be deprived of sockets. If you saw the abbreviation SML, then this indicates that the composition of the products contains a large amount of graphite. In the production process of such pipes, centrifugal casting technology is used . Inside the product are coated in the form of an epoxy composition. This is necessary in order to exclude the likelihood of stratifications and all kinds of precipitation in the inner space. In addition, the described protection has the ability to increase the stability and duration of life.
Pressure pipes of the PRC
Pig-iron sewer pipes (GOST 6942-98) can also be pressure pipes. When you see the acronym CHR, you should know that the products have sockets. Cast iron products do not become less popular even against the background of the fact that the industry produces more modern plastic and steel analogues. Impressive durability can be singled out as the main advantage of cast iron pipes over steel pipes. This is because cast iron does not rust. But cast iron has some disadvantages, first of all, expressed in the relative fragility of products. This circumstance in some cases can cause complex installation.
If you decide to use cast iron sewer pipes for laying the drainage system, their price should interest you. So, a pipe with a diameter of 100 mm and a weight of 24.9 kg will cost 1213 rubles. Before purchasing, you need to decide how long the pipes will be. It is also worth considering the presence of connecting elements.
