Sewer cast iron without sockets - a durable solution for modern installations

At Onninen we specialise in providing the highest quality installation materials.   Cast iron sewer without sockets is one of our flagship products . These systems are becoming increasingly popular in construction. They are distinguished by their exceptional durability and reliability. They are suitable for both new investments and the modernization of older facilities.

Our experience shows that cupless cast iron has many advantages. It is resistant to corrosion and mechanical damage. It dampens vibrations and noise from flowing sewage. It ensures tightness of connections even under heavy loads. These features make it perfect for multi-storey buildings.

Types and applications of socketless sewer cast iron

Our offer includes a wide selection of SML cast iron elements. It includes:

• SML cast iron pipes in diameters from 50 to 200 mm
• Fittings such as elbows, tees and reductions
• Inspection elements - cleaners and plugs
• Specialized solutions such as cast iron siphons

Cast iron systems without sockets are suitable for many applications . They are often installed in high-rise residential and office buildings. They are also suitable for industrial and public utility buildings. Their resistance to high temperatures makes them ideal for discharging hot wastewater.

We recently completed a project for a large hotel complex. We used a complete cast iron system without sockets. It included vertical sewage risers and horizontal drains. The investor appreciated the quiet operation of the installation and its reliability.

Brands of cast iron sewer pipes without sockets available at Onninen

Our offer includes renowned brands of cupless cast iron. These include Preis, HL and Walraven.   Each of these companies is known for innovative solutions and the highest quality products . Their systems are compliant with the latest European standards. They provide reliable operation for decades.

Many customers ask us about the differences between these brands. In our experience, they all offer similar quality. The choice often depends on the individual preferences of the installer. Some value Preis for its wide range of fittings. Others choose HL for its innovative anti-corrosion coatings. Walraven, on the other hand, stands out for its comprehensive fastening solutions.

In everyday practice we see that the compatibility of elements is crucial.   That is why we recommend using complete systems from one manufacturer . This ensures perfect fit and tightness of connections. It also eliminates the risk of warranty problems.

Criteria for selecting socketless sewer cast iron

Choosing the right cast iron system requires taking into account many factors. The most important of them are:

• Purpose and specificity of the building
• Estimated installation load
• Acoustic requirements
• Fire resistance
• Available installation space

At Onninen we offer professional advice when selecting a system . Our experts analyze the project and suggest optimal solutions. We take into account not only the technical aspects. We also consider economic issues and ease of installation.

We often come across questions about pipe diameters. In typical residential installations, pipes of 50-100 mm are mainly used. For risers in tall buildings, we recommend diameters of 150-200 mm. They provide adequate flow and ventilation.

Another important criterion is the type of connections. Non-socket systems use special clamps or compression fittings. They guarantee tightness and compensation for thermal expansion. Some brands offer innovative solutions such as push-in connections. They simplify assembly and increase its speed.

Our experience shows that it is worth paying attention to protective coatings. Modern systems often have double protection. The internal epoxy coating protects against aggressive sewage. The external acrylic layer protects against atmospheric corrosion.

For installations exposed to high mechanical loads, we recommend reinforced systems. They have thicker walls and special connections resistant to stretching. They work well in high-rise buildings and industrial facilities.

Another key aspect is the acoustics of the installation . Cast iron itself has good soundproofing properties. Some systems offer additional soundproofing solutions. These can be special clamps or soundproofing mats. They are worth using especially in hotels or residential buildings.

Many customers ask us about the differences between cast iron and plastics. Cast iron has a clear advantage in terms of durability and fire resistance. It is also quieter in operation. Plastics are lighter and easier to install. The choice depends on the specifics of the project and the investor's preferences.

At Onninen, we offer comprehensive support in designing installations. Our specialists advise on the selection of optimal solutions. We also help in preparing material specifications. We provide training for installers in the field of cast iron system installation.
