ISO 2531 Cement Line Pipe Ductile Iron K Class Length 6 Meter DN80 - 2600

Cement Lined Ductile Iron Pipe overview:

Ductile cast iron is kind of alloy of iron, carbon and silicon, in which graphite exists in the type of spherical, generally the size of graphite is 6-7 class, and spheriodization grade of the pipe should be controlled 1-3 class(spheroidization rate is not below 80%). Thus after spheroidization, ductile cast iron possesses the nature of iron as well as the characteristic of steel. After annealing, its microstructure contains ferrite and a little pearlite possessing excellent mechanical properties.

Push-on Joint T Type Ductile Iron Pipe

Wall thickness& Length:

Pipe wall thickness compliance shall be demonstrated by the manufacturer; a combination of various means may be used, such as: pipe weight control; direct wall thickness measuring or gauging by suitable equipment, such as mechanical or ultrasonic equipment. The frequency of testing is related to the system of production and quality control used by the manufacturer. The length of centrifugally cast pipes with sockets and spigot ends shall be measured by means of suitable equipment, on the first pipe cast from a new mold, for full length pipes, and on the first cut pipe, for pipes which are systematically cut to a predetermined length.

Usage:

Much of the production of ductile iron is in the form of ductile cast iron pipe, used for water and sewer lines. Ductile cast iron pipe is stronger and easier to tap, requires less support and provides greater flow area compared with pipes made from other materials like PVC, concrete, polyethylene or steel. Ductile Iron Pipe is the most widely-used pipeline product in water supply and water drain/sewage projects.
