Corrugated (Serrated) Metal Gasket

No.LL-IFG-02

Corrugated (Serrated) Metal Gasket is a metal-based sealing component with circular corrugations/serrations on its surface. Mostly made of stainless steel, carbon steel, etc., it combines metal rigidity with the elasticity of the corrugated structure, adapting to minor flange surface unevenness with strong sealing stability.

Description

Core Features
· Precision-machined concentric serrated corrugations on a solid metal substrate
· Available in 304/316L stainless steel, carbon steel & custom alloy options
· Dual sealing system: metal serrations + optional flexible graphite/PTFE coating.
· Robust all-metal construction with exceptional mechanical rigidity

Technical Advantages

Excellent resistance to high pressure, high temperature & corrosive media
Superior sealing performance with minimal bolt load requirement
Outstanding anti-fatigue & anti-extrusion performance under cyclic loads
Reusable after disassembly with proper maintenance, reducing long-term costs

Applications

It applies to high-temperature and high-pressure conditions in industries like petrochemicals, power generation, and pressure vessels, and is used for static sealing of equipment such as pipe flanges, heat exchangers, and reactors.

FAQ
1. Who are we?
Anhui Liluan Technology Co., Ltd. is a specialized manufacturer of high-quality insulation materials, established in 2009, with a focus on delivering reliable solutions for various industries.

2. Where are corrugated serrated metal gaskets typically used?

They are ideal for medium-to-high temperature and pressure flange sealing, widely applied in petrochemical, power generation, refining, and pipeline engineering for heat exchangers, pressure vessels, and valve connections.

3. What performance benefits do corrugated serrated metal gaskets provide?

Their serrated corrugated structure delivers uniform sealing stress and excellent resilience. They resist thermal cycling, maintain leak-tight sealing under fluctuating conditions, and can be coated with graphite or PTFE for enhanced performance.

4. Do you offer custom specifications and material options for these gaskets?
Yes. Standard sizes are in stock for fast delivery. Custom dimensions, metal materials (carbon steel, 304/316 SS), and surface coatings are available for bulk industrial project orders.

5. What services can we provide?
We provide comprehensive services, including product consultation, customized design, efficient production, quality assurance, and reliable logistics support to ensure client success.
