JB/T4719-1992 standard heat exchanger spiral wound gasket Model: 1. Usually heat exchanger spiral wound gasket is spiral wound gasket with ribs; 2. Wound gasket spiral wound gasket as a standard part of the structure; 3. Tendons Article usually coated solid ribs or rib double-sided graphite; 4 ribs are welded to the inside of the inner spiral wound gasket, according to different requirements, but also can cut the entire ribs, and the inner ring as the overall , but the price is higher. Heat exchanger spiral wound gasket is designed for heat seal designed ribbed spiral wound gasket can with inner ring is also possible without the inner or outer ring of the type spiral wound gasket usually ribbed External structure as the standard spiral wound gasket according to different working conditions. rib or ribs can be used entity coated tendons. Application:> 1. wound gasket with outer ring normally used in such uneven surface. convex flange parts,> 2 can be based on individual heat exchangers of different conditions and structural requirements. customized heat exchanger spiral wound gasket. outstanding performance:> 1. winding wound gasket surface and the flange face closely. ensure good sealing effect play,> 2 In the alternating temperature and pressure conditions. use prominent effect> 3. inner spiral wound gasket gasket compression performance for providing protection> 4 can be transformed according to the different requirements of the structure and ribs form to ensure optimum sealing effect in different conditions Technical data:> According to different requirements of customers in various forms and materials manufacturing heat exchangers used in metal spiral wound gasket, we also provide on-site mapping and design work.
