Anti Rotation Pinning of Pressure Vessels FIBA

Jun 22, 2018 · If the hole is drilled too deep into the threads and not enough into the flange, the minimum wall thickness of the tube neck will be too low for the pressure rating of the tube and the tube will easily rotate causing leaks and manifold damage. FIBA often re-qualifies tubes for customers on either a five, or ten year cycle. Baffle Plates,Tube Sheets for heat exchangers ,baffle baffle plate is widely used in shell and tube heat exchanger, boiler, pressure vessel, steam turbine, large central air Conditioning, etc. CNC drilled, chamfer, grooved etc as the drawings requirements. Tube holes can be drilled and reamed and can be machined with one or more grooves. This greatly increases the strength of the tube joint.
