SW700金属缠绕垫片由V形或W形不锈钢带和非金属填充料叠合，螺旋卷绕，始末端点焊而成。
TD-SW700Spiral-Wound gasket is formed of V-shaped metallic stripe and soft non-metallic filler by means of piled, spiral wound and connected its end and beginning by dot welded.
采用密封设计准则，通过试验确定了金属缠绕式垫片的垫片系数，在此基础上，按照PVRC新方法对法兰螺栓载荷进行了计算。
The sealing design criteria to measure the factors of spiral wound gasket were adopted, based on this bolt loads of flange can be determined by using the new PVRC method.
以缠绕垫片泄漏率试验为基础，回归得到金属石墨缠绕垫片的泄漏率公式，可较为准确地预估垫片泄漏率并作为评判标准。
Based on the leakage rate test of the spiral gasket, the leakage rate formula was regressed, which was used to predicate the leakage rate of the gasket and toke as the criterion. 2.
