ISO 4179 Coating Cement Lined Ductile Iron Pipe Screw Joint Connection
Self-Restrained joint ductile iron pipe:
Restrained joint in which means provided to prevent separation of the assembled joint. All restrained joints shall be designed to be at least semi-flexible. Produce according to the customer’s requirement. Ductile iron pipeline systems, including pipes, fittings, accessories and joints, consist of various materials.When used for conveying water intended for human consumption, the materials in contact with the water shall meet the relevant requirements of the national standards or regulations in the country of use with respect to effect on water quality.
Specifications:
Ductile iron pipes can undergo large diametral deflections in operation while keeping all their functional characteristics. Allowable pipe diametral deflections, when the pipeline is in service, are given, together with their minimum diametral stiffnesses, which allow the pipes to withstand large heights of cover and/or heavy traffic loads in a wide range of installation conditions. Restrained joints for ductile iron pipelines shall be designed in accordance with ISO 10804. Their spigot external diameters, DE, and their tolerances shall comply with 4.2.2.1.Portland cement mortar, in accordance with ISO 4179; blast furnace slag cement mortar, in accordance with ISO 4179;cement mortar with seal coat, in accordance with ISO 16132.For other types of pipe linings, including their repair method, refer to national standards or the pipe manufacturers.

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.
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.
