Cast iron pipe is used in heating and sewer systems, as well as in the water supply system.
SME and SMU — two types of cast iron pipes, functionally different from each other. Both ends of the SMU type pipe do not have a detachable connection, 3 meters is the standard value for this type of pipe. Pipes of the SME type have one end smooth, the other with a detachable connection, the length of such tubes is from 0.15 to 3.00 meters.
The value characterizing the size of the cast iron pipe is the nominal diameter (DN) — the practical inner diameter. DN size ranges from DN 50 to DN 400.
Pipes made of cast iron are silent and fire resistant, resistant to temperature fluctuations and do not require the use of compensators, however, they are quite fragile and require careful handling.
Has the following areas of application:
• cast-iron sewer pipe — sewer networks of large residential and industrial buildings;

• cast-iron drill pipe – used in drilling operations;
• cast-iron water pipes – water pipelines for various purposes;
• cast-iron gas pipe for the arrangement of gas pipelines;
• cast-iron oil pipe for the construction of oil pipelines.
Depending on the design features and the type of covering materials, the cast iron pipe
