A Parker Hannifin production process based on stainless-steel extrusions is raising the quality and consistency of industry-standard compression tube fittings without increasing the costs.

The technology is aimed at users in processing markets such as oil, gas and chemicals, where the need for integrity and reliability is paramount.

Sheldon Banks, of Parker Hannifin, said: ‘The exceptional uniformity of metal grain size and shape inside extrusion-based parts means that all the new fittings possess virtually identical mechanical properties and are in fact stronger than traditional forged parts.’ Parker Hannifin is releasing extrusion-based products into the mainstream twin-ferrule stainless-steel compression tube fitting market, and is offering the technology on its A- Lok range.

It has been able to make this move thanks to a patented extrusion process that can cope with the tough metals required for tube fittings.

Parker also notes that the process is equally applicable to all the exotic alloy fitting products it supplies for corrosion-resistant applications.

As extrusions allow dimensions to be closely controlled, the fitting interchangeability demanded by large-scale users remains in place.

Extruded profiles are faster to produce, are available with shorter lead times and can typically be produced in smaller batches.

Petrotech Enterprises has stock for these items in its facility in the UAE.

This allows Parker and Petrotech Enterprises to respond more quickly and flexibly to customer requests, especially beneficial for projects requiring exotic materials.

Parker runs an independent intergranular corrosion test before product manufacturing begins, plus a number of unique processing stages aimed at optimising reliability and corrosion resistance.

Parker is phasing this new materials technology into production over the coming months, but will make extruded products available now on a project-by-project basis – due to the extremely positive response it is receiving from customers.
