Continued Success for Heap & Partners PHASE Ball Valves

API 6D Trunnion mounted ball valves proving popular for oil and gas and nuclear applications

Heap & Partners Ltd launched its PHASE brand of API 6D Trunnion mounted ball valves in mid 2011. The company has now now developed the range to cover 1.1/2˝ through 12˝ #600 through 2500. These valves have been covered by a comprehensive fire testing programme which recently resulted in a fire test (ISO 10497) being undertaken on a 12˝ #1500 valve to cover the top end of this range.

Heaps has recently supplied its biggest valve to date; this is pictured along with the respective fire test valve used to cover this application. The valve pictured is a 12˝ ASME 1500 with application specific hubbed ends and double piston effect seats. The valve was extensively tested passing; in house testing in accordance with API 6D, it was then further tested on ambient HP gas (shell and seats) before being stripped, inspected and rebuilt for the required low temperature high pressure gas testing on shell and seats at -46 Degree Celsius.

Heap & Partners has also recently completed a 3-off 3˝ #600 Top Entry Shut Down valve (fully in-line maintainable) for a Nuclear Application in the UK and also delivered its first temporary submersible valves for a PRT (pipeline retrieval application), again for a UK client.

The valves have been developed using a NORSOK driven Supply Chain, focused mainly on UK (or Western European) suppliers. The valves are manufactured to our clients’ very prescriptive specifications in respect of Material Chemistry, NDE / NDT and many other exacting pressure testing requirements.

The client base now includes the majority of UKCNS Operators and Heaps are now looking to extend the into overseas Markets and sectors other than Oil & Gas, this is borne out by the recent Nuclear application referenced above.

The Phase range of valves is available in a number of standard and exotic materials, with Single and Double Piston Effect seating which again can be supplied with either soft or metal to metal seats. Side entry, top entry and Double Block & Bleed versions are all available on short lead times.

If this range of valves is of interest, please contact Heap & Partners to discuss this further.
