What valve material should I use for ethylene cracker furnace crossover?

The pyrolysis furnace crossover operates at 600–900°C - well above the carbon steel Nelson curve for hydrogen service. Specify A217 WC9 (2.25Cr-1Mo) gate valves for Class 600–900 service at these temperatures. For smaller bore instrument connections at the furnace, A182 F22 forged (same Cr-Mo alloy) is used. Confirm compliance with API 941 Nelson curves: WC9 is acceptable up to 600°C at 70 bar H₂ partial pressure without creep concerns.

What is a BS 6364 extended bonnet and when is it required?

BS 6364 is the British Standard for Valves for Cryogenic Service. It specifies that valves handling fluids below −29°C must have an extended bonnet - a lengthened bonnet neck (typically 350–600 mm) that keeps the gland packing and actuator above the cryogenic zone. Without this extension, ice forms at the gland seal, causing leakage and potential valve seizure. Extended bonnets are mandatory for liquid ethylene (−104°C), liquid propylene (−47°C), LNG (−162°C), and liquid nitrogen (−196°C) service.
