Is there a gasket that can be used for high temperature and high pressure lines?
We would like to introduce a gasket that can be used for high temperature and high pressure lines. The spiral type gasket is a high-performance semi-metallic gasket designed for high temperature and high pressure applications. ■ Structure - It consists of alternating layers of a V-shaped metallic thin strip (hoop) and cushioning material (filler) wound in a spiral shape, with the start and end of the winding fixed by spot welding. - There are four types of shapes: basic form, with inner ring, with outer ring, and with both inner and outer rings, tailored to fit the gasket seat of the target flange. ■ Features - Due to its distinctive structure, it can be used at high temperatures and pressures similar to metal gaskets. - It has excellent sealing properties. - It maintains sealing performance even under severe conditions of thermal cycling from low to high temperatures. * DaiKo's product [D1000 Thin Spiral Gasket Graphite (Graphitic Material)] This is a product from our original brand. We also handle products from domestic manufacturers.

basic information
■Things to be careful about with non-asbestos joint sheets 〇 Tighten with sufficient force from the beginning 〇 Do not retighten after a period of time following temperature rise → The gasket hardens due to heat, and retightening after hardening may lead to gasket breakage which could be a concern 〇 Special care is needed when used for steam seals, as hardening is more likely to occur → Compared to asbestos joint sheets, higher tightening force is required, and the lifespan is shorter
