Have you ever struggled to achieve a proper seal on low-pressure flanges? Or wasted time torquing bolts on fragile equipment that can't handle high compression loads? These are daily frustrations for maintenance teams and procurement engineers working with heat exchangers, large-diameter piping, and glass-lined vessels.
The solution? Corrugated metal gaskets. They deliver a reliable seal with significantly lower bolt load than spiral wound or kammprofile gaskets. This means less stress on your flanges, faster installation, and reduced risk of flange damage — all while maintaining leak-tight performance.
At Kaxite Sealing, we've been manufacturing corrugated metal gaskets since 2015. Our corrugated gaskets combine a precision-formed metal core with soft facing materials, creating a sealing solution that conforms to flange irregularities while providing spring-back resilience for repeated thermal cycles.
Engineered to ASME B16.20, fire-safe certified to API 607, and available in over 12 metal and facing combinations, our corrugated metal gaskets are the smart choice for low to medium-pressure applications where flange protection and fast maintenance are priorities.
Feature: Corrugated metal core with soft facing reduces required bolt torque.
Benefit: Prevents flange damage on low-pressure systems, glass-lined vessels, and lightweight equipment.
Feature: Corrugated design provides spring-back action.
Benefit: Maintains sealing force through repeated heating and cooling cycles — no retorquing required.
Feature: 12+ metal alloys and 4 facing materials.
Benefit: Match your gasket to any media — from water and steam to aggressive chemicals and cryogenic services.
Feature: Available from NPS ½″ to 120″ diameter.
Benefit: One supplier for standard and oversized flanges — no gaps in your inventory.
Feature: MTC per EN 10204 3.1, batch‑level documentation.
Benefit: No liability gaps — you can prove material compliance in any audit.
Feature: Direct manufacturing in Ningbo, China.
Benefit: Cuts procurement costs — get wholesale pricing without the wait.
A corrugated metal gasket consists of a precision-formed metal core with corrugated (concentric or spiral) ribs, combined with a soft facing material bonded to both sides. This construction creates a sealing element that combines the strength of metal with the conformability of soft facings, delivering a reliable seal at lower bolt loads than solid metal or spiral wound gaskets.
When bolted between two flanges, the corrugated ribs compress while the soft facing material conforms to flange surface imperfections. This dual‑action sealing mechanism makes corrugated metal gaskets ideal for:
