Standards & Specification Shin Nan ductile iron pipes and fittings for water and sewerage systems are manufactured according to EN 545 / EN 598 / EN 969 / ISO 2531 and under the quality control system of ISO 9001 for quality assurance. The standard nominal sizes DN of pipes to fittings are from 80 mm to 2000 mm. Every pipe and fitting are Downloadable Technical Publications DIPRATechnical Publications DIPRA has a Technical Publication to address virtually every aspect of the application of Ductile Iron Pipe. They are available in PDF format for immediate downloading. The following links organize the Technical Publication by topic.

Ductile Iron Pipe - ResearchGate

Origins of ductile iron performances . ISO Standards - ISO TC 5 SC 2 . TC 5 -Technical Committee 5 . SC - Sub Committees SC1 Steel tubes SC2 Cast iron pipes, fittings and their Ductile Iron Pipe versus HDPE Pipe - LMICOwere conducted on 6-inch and 24-inch diameter Ductile Iron and hdpe pipe. The lowest Pressure Classes available for 6-inch and 24-inch diameter Ductile Iron pipe (350 psi and 200 psi respectively) were used. The hdpe pipe consisted of DR9 and DR11 pipe made from PE 3408 hdpe material. This material is the highest rated material in ANSI/AWWA C906.

Got Certification? Fabricated Ductile Iron Pipe and NSF

Jun 10, 2020 · Fabricated ductile iron pipe must be certified to the NSF/ANSI/CAN 61 standard as a complete finished product. The fabrication and manufacturing process, along with the manufacturing facility, must go through a rigorous certification audit, complete with internal audit checklists and ISO - ISO 9349:2017 - Ductile iron pipes, fittings ISO 9349:2017 gives, in addition to the specifications of the existing International Standards for the conveying ductile iron pipes and fittings, specifications for materials, dimensions and tolerances, mechanical and thermal properties of the thermal insulation layer and external casing of preinsulated ductile iron pipes, fittings and accessories. NAPF 500-03 - The National Association of Pipe FabricatorsAlso, ductile iron pipe has a higher anchor profile as cast than can be achieved with steel by abrasive blasting. The chemistry and metallurgy of ductile iron pipe and fittings versus that of carbon steel result in a surface that has a different texture and color from that of steel. Additionally, the texture and color of ductile iron pipe and

Review of the Bureau of Reclamation's Corrosion Prevention

Ductile iron pipe (DIP) was introduced about 50 years ago as a more economical and better-performing product for water transmission and distribution. As with iron or steel pipes, DIP is subject to corrosion, the rate of which depends on the environment in which the pipe is placed. Standard Index of Specifications for Cast Iron Soil Pipe 2.
