Connecting quality

Bowers Metrology, UK agent for Gagemaker has announced the launch of Gagemaker's Joint Strength System (JSS).

Bowers Metrology, UK agent for Gagemaker – a leading supplier of measurement equipment to the oil and gas sector – has announced the launch of Gagemaker's Joint Strength System (JSS), designed specifically for high accuracy rotary shouldered connection thread inspection.

As the financial and ecological consequences of component failure in the field can be catastrophic in oil and gas applications, the meticulous inspection of all critical aspects of each component is vitally important.

Universally, pitch diameter is used as the ‘control' diameter for the design of each connector. If a connector's pitch diameter is machined incorrectly, the quality of the connector is severely jeopardised. The commonly used ring and plug stand-off gauges that are used for this inspection task are unable to directly detect variations in the component's pitch diameter.

Historically, pitch diameter has remained a connector feature that has been left to interpretation, by the perceived fit of a ring or plug gauge. At best, the ring or plug would identify a discrepancy in either lead, taper or thread form and although any one of these features could render a connector unusable, the manufacturing operator has not been able to identify which element is responsible for the problem.

Simply, Gagemaker's new JSS is an innovative means of accurately gauging the quality of a rotary shouldered connector. The system adds the most important measurement element – pitch diameter – to the criteria currently used to accept or reject a connector's quality.

JSS provides a simple method that enables total control over all of the components contained in a connector assembly. The system combines some of the company's existing gauges with new products, whilst the new easy to use TDWin Taper software enables the selection, calculation, setting and reporting of the measured sizes of the components.

JSS is able to check thread cone taper, thread lead, thread height, thread form, and also pitch diameter at the pitch plane. Following the machining of all of these features, within the allowable tolerances, the offending element can be immediately identified. By using the basic JSS gauge package, manufacturers will now be able to inspect any right hand or left hand rotary shouldered connector, either with or without the use of ring or plug gauges.
