Spec: Coal tar epoxyMin 300 micron DFTCertified to IS standards
A corroded pipeline doesn't give warnings.
Looking for anti-corrosion pipeline coatings but worried about coating failures underground where you can't see them, non-compliant products that won't pass a PSU audit, and suppliers with no real track record in infrastructure?
By the time you see the leak, the damage is already catastrophic — and the cost of repair is 10x doing it right the first time.

Our corrosion protection specialist will recommend the right primer-topcoat system and send complete documentation — TDS, test certificates, IS standard references — everything for tender compliance.
The buried problem — literally
A pipeline goes underground with the wrong coating — insufficient thickness, poor adhesion, wrong primer for the soil condition.
Wrong coating goes underground
Insufficient thickness, poor adhesion, wrong primer.
Nothing. Then the coating disbonds.
For 2–3 years, nothing.
Soil moisture attacks bare steel
Pitting corrosion starts.
Pinhole leaks
By year 5, pinhole leaks.
You're replacing the pipe
By year 7, you're replacing the pipe.
What the coating cost to apply properly.
Plus excavation, traffic diversion, environmental clearances, shutdown losses.
All because the coating supplier cut corners on a product that cost ₹3–5 lakh per km to apply properly.
The compliance disaster
A PSU orders pipeline coating. Spec says coal tar epoxy, minimum 300 micron DFT, certified to IS standards. Your supplier delivered "anti-corrosion coating" — but where's the:
- Test report ✕ MISSING
- Batch certificate ✕ MISSING
- MSDS ✕ MISSING
The auditor asks for documentation. You don't have it. The supplier says "we'll send it" — and never does.
The generalist supplier trap
You need guidance on primer selection for ductile iron pipe in saline coastal soil. You call your coating supplier. They transfer you to "the technical team" —
He reads from the product data sheet — the same one you already have. He's never been to a pipeline site. He can't tell coal tar epoxy from coal tar enamel.
The real cost of "cheapest quote wins"
In tender procurement, lowest bidder wins coating supply. But the cheapest coating just fails first. Recoating a buried pipeline means:
- Re-excavation ₹8–12L / km
- Surface prep AGAIN
- Coating AGAIN
- Backfill AGAIN
- Road restoration AGAIN
Pipeline coatings need a manufacturer who lives in the bitumen and protective coatings world — not a company where coatings are an add-on to their paint business.
When you source from a general paint manufacturer or chemical trader:
- Their QC doesn't test for cathodic disbondment.
- Their sales team doesn't understand pipeline specs.
- Their "technical support" is a brochure PDF.
- When coating fails underground, they blame application.
