New generation of super duplex steels for equipment …

2 New generation of duplex steels Duplex steels owe their name to a two-phase austenitic-ferritic structure with a phase ratio of approximately 1:1 (Fig. 1). Soft ferrite gives steel good plastic properties and prevents chloride-induced corrosion cracking, to which austenite is so sensitive. Austenite provides high corrosion resistance [4,5].

Advantages and disadvantages of globe valve

Disadvantages of globe valve: #1 Pressure drop: Globe valves are known to create a significant pressure drop across the valve when fully open, due to their inherent design. This can reduce the efficiency of the system and require additional energy to maintain flow rates. #2 Size and weight: Globe valves are generally larger and heavier …
