About this service
GI (galvanised iron) is still the right call for specific situations — fire-line risers, bore-well column pipes, exposed external runs in heavy-sun terrace areas, and any place where mechanical impact is a risk. We thread cleanly with a die set, jute-and-Anabond every joint (not just PTFE), and test before sealing. For replacing internal GI with CPVC, we transition with brass female adaptors at the boundary so each material does its job.
Common symptoms we see
- Old GI internal pipes corroded and weeping
- Bore-well column pipe needs replacement
- Exposed external pipe failing in summer heat
- Fire-line maintenance work
How we do it
- 1Thread joints with a die set and lubricant
- 2Jute-and-Anabond on threads; tighten to spec
- 3Pressure-test before painting or burying
- 4Anti-rust paint on exposed sections
Materials we use
Heavy-class GI pipe (B-class minimum), GI sockets and elbows, jute, Anabond, anti-rust primer and finish paint.
Typical duration
Varies; threading slows the work compared to CPVC.
Safety & quality
Threaded GI joints need both jute and Anabond — PTFE alone is not enough on this material.
Frequently asked questions
Should I replace all my old GI with CPVC?
For internal supply, yes — GI corrodes from the inside and the brown flakes you see in tap water come from there. External and fire lines can stay GI.
How long does GI last in Jaipur water?
Internal: 15–25 years before noticeable scale and rust. External painted: 25–30 years.
Can I mix GI and CPVC?
Yes — transition with a brass female adaptor. Direct GI-to-plastic threading damages the plastic threads.
