#SUN"ELL Gaskets - Spiral Wound Gaskets - Low Stress SWG - SUNWELL SW600-LS/LSI Low Stress Spiral Wound Gaskets Code: SUNWELL SW600-LS/LSI Description: Low stress Spiral Wound Gaskets different from standard SWG , it’s offers the same high integrity seal associated with the SWG however, the LS and LSI has been designed in such a way that compression and sealing requirements are achieved under very low seating stresses. These gaskets are intended for use on Class 150 and 300 applications, where customers traditionally do not use the SWG due to concerns about exceeding allowable design stresses. Method 2#: 2~3 ply of the filler & increasing the thickness (0.12MM) winding wire Winding Specification: The gasket should be wound using a minimal pressure. Gasket should be fitted as loose as possible, the gasket should no fall out and must rotate within the outer ring.

Gaskets - Spiral Wound Gaskets - Low Stress SWG - SUNWELL SW600-LS/LSI The SUNWELL CGI Low Stress Spiral Wound Gaskets had been tested in accordance with ASME B16.20-2017 through 3S - SUPERIOR SEALING SERVICES (USA) Initial gasket stress is 35Mpa (5,000psi) and the internal test pressure is set at 20 Bar (290psi), test pressure is maintained for a minimum of 4 hours after which time 3 reading shall be take at 5-minute intervals, an average of the 3 results is then calculated, Test media = Methane. As can be seen from the results, the leakage results were well below the maximum limit set out in...
