Cast iron pipes have been very popular and appreciated for many years and there is no indication that this popularity will fade away. This is largely due to their durability, resistance to mechanical damage and the ability to dampen vibrations. It is worth exploring their uses and learning more about them.

Application of cast iron pipes
Cast iron pipes have a wide range of applications. They can be used to build water, gas and sewage systems. They have a special protective coating that prevents corrosion. It is important to know that the coating cannot contain ingredients that are soluble in water. Cast iron pipes can last up to 100 years, which is largely due to their reliability. First of all, you need to know that cast iron is an alloy of iron and carbon. It has a high content of granite, which is distributed in the matrix and takes the form of small tiles. Thanks to this structure, durable, abrasion-resistant, but also very tight pipes are obtained, but as you can guess, cast iron pipes are heavy. They are resistant to high temperatures. They can be used for installation not only in private homes, but also in public places, such as hospitals, schools and companies. We must also mention that the properties of cast iron improve safety, but also reduce noise. Therefore, there is no need to use additional acoustic or thermal insulation.
What are the types of cast iron pipes?
Depending on the type of carbon, cast iron pipes can be white, gray or semi-finished. The former have a clear breakthrough. Coal is in the form of cement. They are most often used in sanitary installations, while gray cast iron pipes contain carbon, which occurs as graphite. Such cast iron pipes have a wide range of applications and can actually be used for any installation. When it comes to semi-solids, they contain carbon in the form of cement and graphite and also have a wide range of applications. All of them demonstrate really high mechanical strength. Of course, remember that when choosing, you should pay attention to such parameters as:
- degree of impact strength;
- yield strength;
- temporary resistance;
- elongation factor.
Cast iron pipes are wear-resistant. They also demonstrate resistance to compression, good casting properties and fatigue strength. You can also divide them according to their functional properties. In this case, the TML classification is used. There are socketless ones, which have a smooth structure along the entire length, with the bell at one end having a widened diameter. The second type is SME bell-shaped pipes. These are cast iron pipes without a socket and enable quick assembly and disassembly. They are most often used in the installation of external sewage systems. Cast iron sewer pipes are connected using special tightening devices. In this case, the connecting elements should consist of a steel tension collar and a flexible sleeve.
Cast iron pipes available from the Onninen wholesaler
In the Onninen installation wholesaler you will find a variety of cast iron pipes.
Noteworthy is the Preis SML 50x3000 cast iron pipe made of socketless gray cast iron. Cast iron pipe from the Preis brand has a wide range of applications. Perfect for gravity sewage installations, but also for drained installations inside buildings. It is made in accordance with the EN877 standard. For greater durability and resistance to damage, it has a coating of cross-linked epoxy resin. It is applied by spraying. Thanks to this, such pipes will work even in the case of transporting aggressive sewage.
A good choice for many installations will also be the RSP cast iron pipe dn 70 L = 3000 mm KML RSP . It will work even in places where sewage is highly aggressive. It can be used in restaurants, hotel complexes and even supermarkets. The cast iron pipe from RSP is resistant to changing weather conditions, including both temperature and humidity. Pipes can be laid in floor installations, both in sand and concrete.
You can choose a product such as the Preis SML 250x3000 cast iron pipe . It is manufactured in accordance with the EN877 standard. In addition to excellent strength parameters, cast iron pipe also provides acoustic protection. The high density of cast iron and the buffering effect of rubber seals greatly reduce the sound of the material to a minimum, so the drain can be virtually silent. This pipe is also resistant to aggressive sewage.
