*THE ORIGINAL EXCEL FILE IS ATTACHEHD

SUMMARY:1. MAXIMUM ELEMENT STRESS IS 8.2 E+004 Kpa

WHICH IS LESS THAN THE MATERIAL YIELD STRENGTH

2. AVARAGE STRESS IN CRITICAL AREA IS 68 E+004 Kpa SO BY CAMPARING WITH THE MATERIAL YIELD STRENGTH, SYSTEM WOULD BE SAFE WITH SAFTY FACTOR 2.

3. WELDING THROAT THICKNESS MUST BE MINIMUM 0.5” OR MORE
