FAAMATALAGA

1.Tuuina atu o malosiaga sili atu nai lo austenitic ma 22% Cr Duplex Stainless Steels UNS S32760 (F55) e fetaui lelei i le tele o talosaga i alamanuia e pei ole Suauʻu & Gas, CPI(Chemical Processing Alamanuia), ma le gataifale siosiomaga.

O le UNS S32760 (F55 / 1.4501) o lo'o lisiina ile NACE MR 01 75 mo auaunaga fa'afefe ma ua maua le ASME Approval for Pressure Vessel applications.

tulaga malosi e ala i togafitiga vevela faigofie i Tulaga RH 950 ma le TH 1050. O le tulaga maualuga maualuga o le Tulaga CH 900 e ofoina atu le tele o mea lelei pe a faʻatagaina le faʻamama ma le faʻaogaina. I lona tulaga vevela, o lenei u'amea e maua ai mea fa'ainisinia fa'apitoa i le vevela e o'o atu i le 900 °F (482 °C).
