Spiral wound gaskets for pipe flanges spacer size; --- Part 3. spiral wound gaskets technical conditions. This section GB/T 4622 Part 3. This Part replaces GB/T 4622.3-1993 "spiral wound gaskets technical conditions." This section compared with the GB/T 4622.3-1993, the main changes are as follows. --- Modify the process described in the claims section, removed the seal member within the outer weld points specified; --- The original metal strip thickness range 0.15mm ~ 0.25mm modified to 0.15mm ~ 0.23mm, the abolition of the hardness of the metal strip Testing requirements, increase the temperature range of the metal strip, modified temperature range with the filling; --- Part 1 of this standard, revised the terminology gasket; --- Increase the technical requirements for filling tape; --- Filled with added "non-asbestos fibers", filled with original thickness range of 0.3mm ~ 1.0mm to 0.4mm ~ modification 0.8mm; the use of asbestos with increased warnings; --- Modified DN650 ~ DN1200 spacer size D3 and D4, size deviation; --- Modify the thickness of 2.5mm ~ 6.5mm gasket sealing element thickness deviation; --- Modify the thickness of 1.6mm ~ 5.0mm inner gasket, retaining ring thickness deviation; --- The inner belt, positioning spacer ring size D2, D3 unidirectional deviation revised to positive and negative two-way deviation; --- Modified sealing elements, inner and outer diameter measurement and positioning the inner ring; --- Canceled gasket stress relaxation rate, test conditions and steam sealing performance indicators; --- Canceled Appendix A "spiral wound gasket compression, rebound and sealing performance test method" Appendix B "spiral wound gasket stress relaxation test Test methods ", in direct reference to the current standard test method standards.
