Flanges are tightened according to “CBT-001 Assembly & Tightening of Bolted Flanged Connections” procedure. The tools are utilized according to the manufacturer’s instructions in which all relevant safety standards are complied with. For every flange to be tightened under controlled conditions within a project, a written protocol/procedure will be submitted to our technician with the required values.​​​ After the controlled tightening of the flanged connection, a flange-label will be applied referring to a flange report that will be submitted to the customer for approval that the flange has been tightened correctly. A copy of the calibration certificate of the utilized pump, will be handed over.
