A new strategy to improve the stem sealing[R]
How to counter the usual valve packing relaxation The current experimental and operative evidences show that the stem graphite sealing incurs a gradual relaxation that comes in the first weeks …
High machinability of duplex and and use of hollow bar to improve productivity[R]
Faster machining, shorter production timeLess tangled chips due to minimizing boring (internal turning) which is the most demanding operation of all machining operations in duplex stainless steel

Selection and Application of Nickel Aluminium Bronze Isolation Valves
Nickel Aluminium Bronze typically finds use in applications where seawater or brine is present; providing a long service life far exceeding that of rubber-lined or ferrous based steel valves used on the same service.
The whole-life cost of using a Nickel Aluminium Bronze valve in seawater applications is economically superior to other solutions, when considering additional inspection, maintenance and service costs and that of whole valve replacement, typically required when other solutions are adopted.
Nickel Aluminium Bronze may not enjoy the notoriety of other materials; this presentation contains information which can assist in the correct selection and application of valves manufactured from Nickel Aluminium Bronze.
Mechanical components for functional safety applications (SIL): Standardization urgently needed!
Why is this?
Main difference: failure rate data for mechanical components
Some people even question the assessment of mechanical components in general:“Is it really necessary to include mechanical components in the SIL assessment?”
