At Kriloha Ltd., we recognize that as refineries and chemical plants push for higher efficiencies, the pressures in heat exchanger headers are climbing. A standard solid metal gasket requires massive torque to seal, often risking damage to the header box threads. The Kriloha Kammprofile Header Plug Gasket is our high-performance alternative. As a premier global supplier of industrial seals, Kriloha Gaskets has adapted the legendary Kammprofile technology specifically for the small-diameter, high-stress environment of header plugs.
The architecture of this gasket is a masterclass in localized stress management. Instead of a flat piece of metal, we machine concentric serrations into a solid 316L Stainless Steel or Soft Iron core. We then bond flexible graphite to both faces. When the header plug is torqued, the serrations act like a series of high-pressure “teeth,” biting into the graphite and forcing it into the flange face and the plug shoulder. This creates multiple redundant sealing rings. Even if the internal-most ring is bypassed, the subsequent serrated rings act as independent barriers, ensuring absolute containment.
Manufacturing these gaskets at Kriloha involves precision CNC machining to ensure the serration pitch and depth are optimized for the small surface area of a header plug. We ensure the hardness of the core is strictly controlled to ensure the gasket remains the sacrificial element in the joint. By choosing Kriloha Ltd., you are investing in a “High-Integrity” seal that reduces the mechanical stress on your header box while providing a significantly more reliable barrier than traditional metallic washers.
