Comprehensive Corrosion Protection

Each ductile iron flanged pipe is internally lined with cement mortar and externally coated with fusion bonded epoxy or bitumen. This dual-layer protection secures the pipes against corrosion, ensuring longevity even in harsh environments. Temporary end caps are fitted to prevent contamination during handling and transportation, which is particularly beneficial for water transmission and industrial pipelines.

Precision Manufacturing Standards

Manufactured to strict tolerances of 1% and marked with standard and batch numbers, every pipe meets the requirements of IS 8329, ISO 2531, and EN 545. Hydrostatic testing at up to 1.5 times rated pressure guarantees performance and safety. Available in thicknesses from 5 mm to 20 mm, these pipes can handle rated pressures of PN 10, PN 16, or PN 25 as specified.

Versatile Application and Easy Installation

Fitted with flanged ends, bolts, and robust gaskets, these pipes can be quickly joined for both underground and overground use. Their rigidity and robust sealing minimize leakage risk, making them ideal for water supply, sewage, irrigation, and fire fighting lines. Packing can be customized as loose or bundled to accommodate specific site requirements.

FAQs of Ductile Iron Flanged Pipes:

Q: How are ductile iron flanged pipes joined and sealed?

A: These pipes feature flanged ends that are connected using bolts and gaskets, typically made of rubber or EPDM. This design creates a secure, leak-proof seal suitable for both underground and overground installations.

Q: What kind of corrosion protection is provided for these pipes?

A: To ensure long-term durability, the pipes are coated internally with cement mortar and externally with fusion bonded epoxy or bitumen. This protects against corrosion from water, wastewater, and industrial fluids.

Q: When should I choose flanged joint ductile iron pipes over other types?

A: Flanged joint pipes are ideal when you need strong, rigid connections that can be easily assembled or disassembled, particularly in water supply, fire fighting, and industrial pipeline systems where secure sealing and durability are priorities.

Q: Where can ductile iron flanged pipes be installed?

A: These pipes are suitable for both underground and overground applications, allowing use in municipal water supply, wastewater networks, etc. Their robust construction supports installation in varied environments.

Q: What is the typical process for handling and installing these pipes?

A: The pipes are delivered either loose or bundled, with protective end caps. Installation involves aligning the flanges, fitting gaskets, and bolting the joints securely. Hydrostatic testing should be conducted after assembly to verify sealing integrity.

Q: What are the main benefits of using ductile iron flanged pipes?

A: They offer high mechanical strength, reliable sealing, long service life due to advanced corrosion protection, and compliance with international standards. Their versatility supports application in water, sewage, industrial, and firefighting pipelines.
