Qualification, Testing & R&D
Qualification standards are an international requirement for the high integrity, critical applications in the oil and gas industry. Our significant history of qualifying valves to API, ISO, GOST, BS, Oil and Gas company and other international standards has meant that our process and rigour of qualification has been developed, tried, tested and embedded in our quality system. The global demand for valves to be qualified is growing and understanding the nature of these requirements is imperative for any valve supplier.
Our qualification processes include:
- API PR2, ISO and other International Standards
- Endurance Testing
- Hyperbaric Testing
- Safety assessment
- Cryogenic Testing
- Fire Testing
The BEL Valves portfolio products are qualified to API 6A, 6D, 6DSS and 17D, ISO and ANSI equivalents and also specific oil and gas company standards.
Qualification of our high integrity valves provides customers with a guarantee and reassurance of quality, safety and reliability. The specific goals being:
- The ability to seal against leakage over a given number of cycles
- Confirm that seals perform and low and high temperature
- To determine the fugitive emissions performance across temperature ranges
- Prove environmental containment
- Prove soft and metallic seal combinations
- Validate operating torque across temperature ranges
FEA Finite Element Analysis
Maximising the durability within the design of the valve is critical to its in service life and reliability. To aid in the prediction of the valve to withstand the mechanical stresses created during operating conditions we use Finite Element Analysis as one of our tools.
FEA most often involves the determination of stress intensity factors.
These types of fracture mechanics more accurately predict the stress state within the design material, a critical factor in the design of high pressure valves.
We have integrated FEA into our design cycle as part of our continued improvements to reliability, safety, quality and cost effectiveness.
Such models accurately determine deformation and stresses created in the ‘real world’.
In addition to considering a part’s ability to withstand the mechanical stresses created during use the FEA software enables our engineers to predict the effects of extreme temperatures or temperature changes (heat transfer analysis) and the flow of fluids through and around objects (fluid flow analysis).
