Ductile iron pipe is a kind of pipe made by adding ductile agent to hot metal above 18# and then processing it by centrifugal ductile iron machine at high speed. This kind of pipe is also called cast iron pipe, or simply pipe. Its characteristics are very unique, both the strength and hardness of iron, but also the toughness and wear resistance of steel. In addition, its corrosion resistance is also very good, can resist a variety of harsh environment erosion. At the same time, the ductility of ductile iron pipe is also very good, and it is very convenient to install. Therefore, it is widely used in water supply, gas transmission, oil transmission and other projects of municipal industrial and mining enterprises.
Big steel products strictly comply with the following standards in the production process:
The ISO 2531 standard specifies requirements and test methods for ductile iron pipes, fittings and accessories for pressure piping.
The BSEN545 standard specifies the requirements and test methods for ductile iron pipes, fittings, accessories and their joints for water pipelines.
The BSEN598 standard specifies the requirements and test methods for nodular cast iron pipes, fittings, accessories and their joints for sewage treatment.
The ISO7186 standard specifies the requirements for nodular cast iron pipes, fittings, fittings and joints for external drains and sewers.
ISO4179 standard specifies the general requirements for centrifugal cement mortar lining of ductile iron pipes for pressure and non-pressure pipes.
The ISO8179 standard specifies the requirements for external galvanizing of ductile iron pipes.
The ISO4633 standard specifies the requirements for rubber seals, which are mainly used as connection rings for water supply, drainage and sewage pipes.
In addition, ductile iron pipes can also be equipped with polyethylene sleeves to enhance their corrosion resistance and service life.
