Characteristics of cast iron sewerage

iron drain pipe and the main types of

To date, there are several varieties of pipes made from this material.In order to make the drainage system properly, you need to understand their distinctive characteristics.

• pressure pipes.Short name - Ductile Iron, which means "high-strength cast iron with nodular graphite";
• Pressure flared tubing.Short name - CHNR, which means "iron flared pressure";
• Bezrastrubnye pipe (abbreviated SML);
• Gravity pipe abbreviated name - the Cheka (cast iron sewer);

Brief Description Ductile iron sewer

This kind of product is made by modifying its magnesium.In processing, mini-spheres are formed of graphite, which give the material strength and ductility.The possibility of formation of cracks is minimized.This type of cast iron, their properties, similar to carbon steel.

Accordingly, the pipe CHSHG characteristic:

• elasticity;
• resistance to corrosion;
• flexural strength;
• impact;
• adaptability to climate change.

Most often, CHSHG pipe applies:

• for the construction of sewerage networks;
• to supply drinking water to the population;
• The highways working under pressure (withstand up to 1.8 MPa);
• The rigs;
• For transportation of gas;
• to transport oil.

Short description flared iron sewer CHNR

CHNR tubes used most often during the installation of pressure systems in various industries.Unlike analog metal, cast iron does not rust, it is their great advantage.However, they are more fragile and therefore more problems can arise when installing them.Cutting of the pipe runs perpendicular to its axis.It is advisable not to exceed the deviation is more than 5 degrees.

CHNR To further protect the pipe from corrosion, use lacquer-bituminous coating, but without them the life of the cast-iron pipe rolling may be more than 50 years.CHNR pipe used for underground and ground-mounted heating systems, sewerage and water supply systems.

Short description bezrastrubnogo cast iron sewer pipe SML

SML is made by centrifugal casting and are characterized by a high content of graphite.Its inner side is coated with epoxy compound, therefore the probability of precipitation and layers inside of the pipe is reduced to a minimum.Parameters such as increased durability and stability, even when exposed to aggressive substances.

Such a product characterized by high strength, low wearability, impact resistance, acoustic comfort, fire resistance, corrosion resistance, ability to withstand high temperatures.

Brief description of non-pressure cast iron sewer pipe - CHK CHK

pipe is made of gray cast iron, and it has a plastic form of graphite.Its strength is lower than that of ductile iron pipe.Pipe CHK is used in environments where extreme loads are not provided.In addition, it is the socket.At one end of the tube extension is present, which provides a qualitative and reliable connection thereto of another pipe.Most often, cast iron sewage serve to remove economic, domestic and sewage in small industrial and residential buildings.Their great use at their summer cottage, as they are durable.HC pipe can be installed in conjunction with the plastic.Transitional cuff made of rubber will provide secure attachment at the joints.Such HC pipe can be easily dismantled and reused.
