Don't you want to eliminate the troublesome task of peeling off gaskets that have adhered to flanges by using Klinger joint sheets? Klinger gaskets have a surface treatment that makes them less likely to stick, significantly reducing this task. From a cost-effectiveness perspective, if adhesion can be reduced, the overall maintenance costs for the plant can be greatly decreased, and the benefits should be substantial. Why not consider changing the gaskets you use at this opportunity?

Regular sheet gaskets harden over time after installation and stick to the flange. Field workers must use scrapers and other tools to clean off the old gaskets that have become severely adhered to the flange surface. Klinger's sheet gaskets have a special surface treatment that significantly reduces the degree of adhesion. In plant piping maintenance, the costly item is not the purchase price of the gaskets but the labor costs. Why not take this opportunity to consider improving work efficiency?

• Ring joint gaskets are heavy-duty, high-pressure gaskets primarily used in petrochemical applications both offshore and onshore. They are precision-machined components used in conjunction with precision-machined flanges. Clinger's ring joint gaskets are manufactured in accordance with ASME B16.20 and API 6A. • The selection of gasket material is based on several criteria, with chemical compatibility with the fluid and the hardness of the flange being prioritized. Ideally, the hardness of the gasket material should be about 30 Brinell hardness points lower than that of the flange to ensure that the gasket can deform sufficiently without damaging the flange surface. • Worn, pitted, or corroded sealing surfaces on flanges can compromise the sealing performance of ring joint gaskets.

Features of the Spiral Wound Gasket 'Maxiflex' The spiral wound gasket can compensate for load fluctuations caused by variations in fluid pressure and temperature, temperature differences on flange surfaces, flange rotation, bolt stress relaxation, and permanent deformation. The sealing part of the spiral wound gasket consists of a layer of metal foil called a hoop and a layer of soft, highly compressible sealing material known as filler, wound in a spiral shape. When compressed during installation, the sealing material fills the irregularities of the flange surface. The metal foil supports the filler while providing the gasket with mechanical strength and flexibility. The Maxiflex spiral wound gasket allows for the selection of filler material based on usage conditions. Design Guidelines for Klinger Spiral Wound Gaskets In the sealing part of the spiral wound gasket, a V-shaped cross-section hoop material is wound together with a soft filler in a spiral manner. To enhance mechanical strength and sealing performance, the beginning and end of the winding consist only of hoop material, and the entire circumference is spot-welded. By maintaining consistent tension during the winding process, a uniform thickness is achieved. As a result, the gasket has a high recovery rate, allowing for reliable surface pressure even under varying operating conditions.
