UK-based seals manufacturer Precision Polymer Engineering (PPE) says it is the first company of its kind outside the Americas to receive accreditation under the National Aerospace and Defense Contractors Accreditation Program (Nadcap) for the production of its elastomer seals.
Nadcap was established in 1990 and serves as a global certification programme for the aerospace engineering, defence and related industries.
It is administered by nonprofit organisation the Performance Review Institute (PRI), which aims to advance the interests of the mobility and related industries through development of performance standards and the administration of quality assurance, accreditation and certification programmes.
Nadcap is the highest standard accredi- tation awarded to suppliers to the aerospace industry and provides an assurance of quality and integrity in component manufacture.
Accreditation is awarded only after a rigorous audit of an organisation’s qual- ity and manufacturing systems. The audit covers processes throughout the business, from raw materials, tooling and manufacturing to inspection, packaging and dispatch.
“This accreditation is a great achievement for PPE and reflects our commitment to quality and continuous improvement in all aspects of our business,” says PPE MD Paul Gillyon.
PRI COO Joe Pinto adds that achieving Nadcap accreditation is not easy, as it is one of the ways in which the aerospace industry identifies companies who excel at manufacturing high-quality products through superior processes.
Pinto went on to say that PRI is proud to support the continual improvement of the aerospace industry by assisting com- panies such as PPE in achieving success. “We look forward to continuing to assist the industry moving forward,” he states.
Meanwhile, in August, PPE announced its latest developments in ultrahigh temperature and extreme-low-temperature- resistant Perlast perfluoroelastomer and Endura seals for high-performance, high-temperature and low-temperature offshore applications.
For continuous use at high temperatures, without loss of mechanical performance, PPE has developed perfluoroelastomer Perlast G75TX for processes up to 327 ºC, together with fluoroelastomer V91J for continuous exposure at 250 °C.
Further overcoming the traditional weakness of perfluoroelastomers at low temperature, all-round sealing performer Perlast G92E is capable of subzero opera- tion down to –30 ºC at pressures up to 5 500 psi.
PPE says its Endura range of oilfield elastomers has been specifically developed for use in downhole, surface and subsea oilfield equipment and offers rapid gas decompression (RGD) resistance. Many of the Endura materials have been tested to international RGD standards.
It adds that it has, over the past 25 years, supplied O-rings and custom seals for systems operating in the most inhospitable subsea environments in the world at temperatures ranging from –46 ºC to 327 ºC.
Earlier this year, the company reported that it had invested in new production equipment to meet the growing demand for its Endura seals from major oil and gas companies around the world.
New moulding press equipment was installed at the manufacturer’s Blackburn factory, in the UK, in March.
In procuring the presses, one of the company’s objectives was to increase production efficiency by reducing setup times.
“This has been achieved by an innovative combination of equipment configuration using magnet platens and computer control, together delivering a 40% increase in available Endura manufacturing capacity. To operate the new moulding presses, production staffing has been increased by 5%,” it states.
