Product Description

ISO4179 Cement Lined Ductile Iron Pipe External Zinc and bitumen coating as per ISO8179


 Ductile Iron Pipe overview:

Dutile iron pipe under EN598 standard shall be delivered with an external coating of zinc with finishing layer and an internal lining of high alumina cement mortar,This shall not preclude special coating arrangements for products which deviate from the requirements  for specific design reasons. Pipes for sewers and drains shall be identified externally by one of the following colours: brown, red or grey. This is to allow easy identification of installed sewers and drains. Pipes specifically intended for rain water or surface water sewers (separate systems) may be identified by a different colour other than those used for potable water pipes.The iron thickness of fittings used for pressure sewers shall be in accordance with EN 545, The iron thickness of fittings used for gravity sewers shall be equal to or higher than those of pipes of the same DN.





Table 1 — Limit deviation on internal diameter




Limit deviation a


80 to 1000 - 10
1100 to 2000 - 0,01 DN
a The lower limit only is given.


Pipes shall be supplied to the standardized lengths given in Table 2.


Table 2 — Standardized length of socket and spigot pipes




Standardized length Lu a


80 to 600 3 or 5 or 5,5 or 6
700 to 800 5,5 or 6 or 7
900 to 1400 6 or 7 or 8,15
1500 to 2000 8,15


Pipes shall be designed to a length taken in the range: standardized length plus or minus the permissible deviation; they shall be manufactured to this design length plus or minus the limit deviation .


The manufacturer shall make the information available as to his design lengths.


The length shall be measured according to 6.1.4 and shall be within the limit deviations.


Of the total number of socket and spigot pipes to be supplied in each diameter, the percentage of shorter pipes shall not exceed 10 %, in which case the length reduction shall be:

  • up to 0,15 m for the pipes in which samples have been cut for testing (see 4.3);
  • up to 2 m by increments of 0,5 m for DN < 700;
  • up to 3 m by increments of 0,1 m for DN ³ 700.



Packing: bundled with steel belts or in bulk

Shipment: in bulk or container.


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.


Our advantages:

There are lots of qualified managers and technicians, and a well-trained team of after-sales service, which provides all services of manufacture, package, transportation and installation. We are looking forward to cooperating with friends from abroad and home creating a brighter future.
