缠绕垫片系数 m=2.5-4 缠绕垫片使用压力 ≤25MPa 缠绕垫片使用温度 -196℃-700℃(氧化性介质中不高于600℃) 缠绕垫片最小预紧比压 y=68MPa 下表是缠绕垫片直径公差(即用于法兰的名义管道直径) DIM(mm)ANSI B16.5
BS1560(mm)
Mss sp-44API605公差内环内径
垫片内径<=600<=24>=26 and <=34±0.5>600 and <=800>24 and <=34>=36 and <=60±0.9>800 and <=1600>34 and <=60 ±1.3>1600>60 ±1.6垫片外径<=600<=24<=24±0.9>600 and <=160000>24 and <=60 ±1.81600>60 ±2.2外环外径 >1/2 and <=60±0.9<=600<=24 0-1.0>600 and <=1000>24 and <=34 0-1.8>1000 and <=1600>34 and <=60 0-2.2
