Controlled Bolting Services


Like welded joints, bolted joints too have gained serious attention due to the consequences of improper tightening of bolted joints. It requires tremendous expertise to ensure leakage-free bolted joints. Controlled tightening of bolted joints is a completely scientific method of torquing and tensioning in a systematic manner with identification and traceability in its place.
