2 BLJ technicians were engaged to perform an on-line leak seal  and repair to 1000kpa bonnet leak on a sour waterline, while the Petrochemical plant remained on-line, to reduce client down time. Highly trained Technicians changed out studs one at a time and installed injection washers, peen gap on bonnet flange and injected compound into the joint to provide seal leak.
