6. A PIPE CARRY|NG STE AM AT 3.5 MPa HAS AN OUTSIDE DIAMETER OF 450 mm AND A WALL THICKNESS OF 1D mm. A GASKET IS INSERTED BETWEEN THE FLANGE AT ONE END OF THE PIPE AND A FLAT PLATE USED TO CAP THE END. HOW MANY 40 mm- DIAMETER BOLTS MUST BE USED TO HOLD THE CAP ON IF THE ALLOWABLE STRESS IN THE BOLTS IS 105 MPa, OF WHICH 55 MPa IS THE INITIAL STRESS? WNHAT CIRCUMFERENTIAL IN THE PIPE ? TO TIGHTEN THE BOLT INITIALLY AND WHAT WILL STRESS IS DEVELOP WHY IS IT NECESSARY HAPPEN IF THE STEAM PRESSURE SHOULD CAUSE THE STRESS IN THE BOLTS TO BE TWICE THE VALUE OF THE INIIAL STRESS ?
