TD-DJ710金属包覆垫片Metal jacketed gasket
TD-DJ710以柔性石墨、陶瓷纤维、石棉及无石棉板作为填充，外包不锈钢、马口铁、紫铜等各种材质的金属薄板而成，特别适用热交换器、压力容器等高温高压密封部位。它有效防止垫片的散架、介质的侵蚀，同时也提高了耐压.
TD-DJ710 is made of graphite, ceramic, non-asbestos etc. filler covered with thin metal jacket, such as stainless steel, carbon steel, copper etc. By their sealing efficiently, provide outstanding resilience, while the metal jacket guarantees excellent sealing and protects the filler against pressure conditions, fluctuating temperatures and corrosion.
适合于热交换器、气体管道、铸铁法兰、汽缸头以及锅炉及其它容器。
一般在安装时，可压制垫片初始厚度有30%的变形，这样可有效密封法兰的不平整和小缺陷。通过选择不同的金属及填充材料可适用于各种不同的介质。
TD-DJ710 is particularly suitable for sealing flat surfaces of heat exchanges, gas pipes, cast iron flanges, cylinder heads of engines as well as for boilers and other vessels.
By their sealing efficiently, provided by exerting strong pressure on circular rimes of the flanges, metal-jacketed gaskets can stand up to 30% deviation from the initial thickness, which is very useful in case of irregular or faulty flange rims. The chemical compatibility of the metal and the medium being sealed should be considered.
