FAQS on ductile iron pipe repair couplings

Q: What is a ductile iron pipe repair coupling used for?

A: A ductile iron pipe repair coupling is designed to quickly fix leaks or joint failures in ductile iron pipelines. It provides a rigid, corrosion-resistant connection without requiring welding or specialized tools. These couplings are ideal for permanent repairs in water, sewage, or gas systems.

Q: How do ductile iron pipe repair clamps work?

A: Ductile iron pipe repair clamps use a bolted, split-shell design to seal damaged pipe sections. They create pressure-tight seals by compressing rubber gaskets against the pipe surface. These clamps are suitable for temporary or permanent repairs on cracks, holes, or joint misalignments.

Q: What materials are used in ductile iron repair clamps?

A: Ductile iron repair clamps are made of high-strength ductile iron for durability, with EPDM or nitrile rubber gaskets for leak-proof sealing. Bolts and nuts are typically hot-dip galvanized or stainless steel to resist corrosion. This ensures compliance with industry standards like AWWA or ISO.

Q: When should I use a repair coupling vs. a repair clamp?

A: Use a repair coupling for full-circumferential pipe breaks or complete joint replacements. Repair clamps are better for localized damage like cracks or small holes. Couplings provide rigid structural support, while clamps offer faster installation for emergency fixes.

Q: Are ductile iron repair products suitable for high-pressure systems?

A: Yes, ductile iron repair couplings and clamps are rated for high-pressure applications up to 350 PSI or more, depending on the model. They undergo rigorous testing to meet pressure and load-bearing requirements. Always verify the product’s pressure rating against your system’s specifications before installation.
