Features and benefits
1.Min design temperature: －196℃.
2.Extended bonnet to keep stem packing at sufficient distance away from the cold fluid to remain functional.
3.Extended bonnet as per MESC SPE 77/200 & SPE 77/209 /as per customers requirements.
4.The main pressure containing components are treated with liquid nitrogen to stabilize dimensions and eliminate the stress caused by metal microstructure changes.
5.Low emission packing.
