API650 Wind Girder Weld to Shell

API650 Wind Girder Weld to Shell

API650 Wind Girder Weld to Shell

API 650 weld of Wind Girder to Shell is not addressed.

ASME VII Sec 8 , UG-30 has rules for stiffener to shell as stitch weld with 2" min by 8t on both sides.

For a   3/16" shell, this is almost continuous welding and seems excessive.

Does anyone have a rule of thumb for this weld attachement of wind stiffener to shell???

RE: API650 Wind Girder Weld to Shell

My interpretation is a continous weld around the entire tank.  Sometimes a continous weld isn't needed for strength, but to seal against moisture.

RE: API650 Wind Girder Weld to Shell part b says that the horizontal weld attaching the WG to the shell shall be a continous weld.  Use Section to determine the weld size.

Do as the book says, don't be fooled by your thumb
