Special fastener orders hit £1M

James Walker RotaBolt's high-tech version of the Indicating Rod Bolt has been specified for pressure vessels and heat exchangers in Nigeria and Peru. With more work in the pipeline from Algeria and Nigeria, orders are likely to exceed £1-million.
The high performance version of the Indicating Rod Bolt was developed after RotaBolt was approached by a major EPC contractor and a vessel manufacturer, who had experienced difficulties with heat exchangers on LNG trains at a major plant in Africa.
   A standard Indicating Rod Bolt uses direct length measurement to gauge the delivery of load. Such fasteners had been specified on the African project but were failing to provide the control that was necessary to assure fully sealed flange joints under test conditions.
   RotaBolt's new version of the fastener gives a far more accurate measurement of bolt tension from the length extension. This guarantees the uniform delivery and maintenance of load.
   The new bolts are individually load test calibrated and fitted with a special indicator to measure extension. Every bolt's extension measurement is certified.
   "These orders are a testament to our skills and expertise in assuring bolted joint integrity", said Rod Corbett, managing director of James Walker RotaBolt.
"What started as a challenge from one of our clients has been turned into a major success story through the application of our knowledge."
