Cast iron sewer pipes have a large margin of safety, they undergo significant stress during operation. This makes such products universal, which indicates that they can be used both in private and industrial construction.
Varieties of cast iron pipes
On sale today you can find cast iron pipes for transporting liquids under pressure or without pressure. It is possible to purchase socketless and pressure socket products.
If you see cast iron sewer pipes with the abbreviation VChShG, this indicates that you have a high-strength material with nodular 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 perfectly cope with impacts and show durability onbending, in addition, they are not exposed to corrosion for a long time. You can use them in almost any conditions, as products of this kind adapt perfectly.
Free-flow pipes ChK
Cast iron sewer pipes can also be non-pressure. 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, so they are used where the system will not be subjected to impressive loads.
If there is a need to provide high-quality fastening, then it is worth purchasing socket products. They have an extension.
Such non-pressure 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.
SML sewer pipes
Cast iron sewer pipes may be devoid 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. From the inside, the products are coated with an epoxy composition. This is necessary in order to exclude the possibility of deposits and all kinds of precipitation in the internal space. In addition, atdescribed protection has the ability to increase stability and lifespan.
Pressure pipes CPR
Pig-iron sewer pipes (GOST 6942-98) can also be pressure. When you see the abbreviation CHNR, you should know that the products have sockets. Cast iron products are not becoming less popular even as the industry produces more modern plastic and steel counterparts. In the role of the main advantage of cast-iron pipes over steel pipes, impressive durability can be distinguished. This is because cast iron does not rust. But cast iron also has some disadvantages, primarily expressed in the relative fragility of the products. This circumstance in some cases can cause difficult installation.
If you decide to use cast-iron sewer pipes for laying a sewerage 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 needed. It is also worth considering the presence of connecting elements.
