KAMMPRO-SPIRAL (Hybrid High-Performance Gasket)

At Kriloha Ltd., we recognize that some industrial applications push standard sealing technology to its absolute breaking point. When a standard spiral wound gasket isn’t enough, and a solid metal gasket is too rigid, the Kriloha KAMMPRO-SPIRAL emerges as the ultimate hybrid solution. As the top supplier of rubber seals and gaskets, our Kriloha Gaskets brand has developed this “Super-Seal” to provide an extra layer of security for the world’s most dangerous and high-pressure fluid systems.

The KAMMPRO-SPIRAL is a masterclass in mechanical engineering. It features a central, solid metal core that is precision-machined with concentric serrations (the Kammprofile element). This core is then integrated with a secondary spiral-wound sealing element on the outer perimeter. This creates two distinct sealing zones. The serrated core “bites” into the filler material (Graphite or PTFE) to create a high-density primary seal that resists lateral movement, while the spiral winding acts as a secondary buffer, providing the “spring” needed to recover during thermal cycling.

The primary advantage of the Kriloha KAMMPRO-SPIRAL is its resistance to “blow-out.” In high-pressure steam or chemical service, internal pressure can sometimes push a standard gasket out of its seat. Because our hybrid design uses a solid metal core as its foundation, it provides structural rigidity that a standard winding simply cannot match. Furthermore, our Kriloha-Bond™ technology ensures that the transition between the serrated core and the spiral winding is seamless, preventing any internal leak paths from forming at the interface.

Despite its rugged construction, the KAMMPRO-SPIRAL is designed for efficiency. It requires significantly less bolt load to seat than a traditional grooved metal gasket, which protects your flanges from long-term warping and stress. For engineers managing “Bad Actor” flanges—those joints that seem to leak regardless of the gasket used—the Kriloha KAMMPRO-SPIRAL is the final answer. It is more than a gasket; it is an insurance policy for your piping integrity, ensuring that your most hazardous processes remain safely contained under all operating conditions.

Primary Use Cases

Critical “Bad Actor” Flanges: The definitive solution for joints with a history of persistent leaking.
High-Pressure Steam Turbines: Sealing main steam inlets and extraction lines in power plants.
Hydrocarbon Reactors: Used in high-pressure, high-temperature catalytic cracking and hydroprocessing units.
Offshore Subsea Piping: Providing maximum security in inaccessible underwater environments where repair costs are astronomical.
Large Diameter Heat Exchangers: Managing the massive radial forces and thermal expansion of heavy industrial vessels.

FAQs

What makes the KAMMPRO-SPIRAL better than a standard SWG?

It offers redundant sealing. The solid serrated core provides blowout resistance and rigidity, while the spiral winding provides recovery. It is essentially two gaskets in one for maximum security.

Does this gasket require special flanges?

No. The KAMMPRO-SPIRAL is designed to fit standard ASME B16.5 and B16.47 flanges, though it is most commonly used in higher pressure classes (Class 600 and up).

Is the filler material the same as a standard gasket?

Yes, we typically use high-purity flexible graphite or PTFE. However, because of the serrated core, the filler is compressed more efficiently, creating a tighter seal.

Can I use this on a flange with surface damage?

The hybrid design is excellent for slightly worn flanges. The spiral-wound portion conforms to irregularities, while the serrated core provides the high-pressure block.

How do I specify the metallurgy for a KAMMPRO-SPIRAL?

The core and the winding should be matched to your process media. Kriloha offers everything from 316L for general steam to Hastelloy for highly corrosive acids.
