Rock bolt mining Britannica

The most common form of mechanically anchored rock bolt uses an expansion shell.A wedge attached to the bolt shank is pulled into a conical expansion shell as the bolt is rotated.This forces the shell to expand against the wall of the borehole.The two mechanisms by which the shell is anchored against the borehole wall are friction and interlock.Reinforcing ring - Storage tank engineering - Eng-TipsThe shell of the tank acts as one flange,and the leg of the angle acts as the other. please do ask.RE Reinforcing ring MJCronin (Mechanical) 18 Apr 13 15:15.I believe that this is a standard detail for an API-650 style stiffening ring - at the top of the shell. this puts you in quite a bind.If you can competitively burn and break Reinforcing Pad - piping-designerHome Disciplines Mechanical Stationary Equipment TankReinforcing Pad.Email Print Reinforcing Pad.Written by Jerry Ratzlaff on 17 February 2016.Posted in Tank.A plate formed to the shape of the tank or vessel around a nozzle for extra strength.Also known as repad or weld pad.standatds API Standards.tankAPI Std 650 - Standard for Welded
