Ukufakwa kwe-chromium kudlulisela ukumelana kahle kokugqwala kwe-Autenitic grade 304. Noma kunjalo, ukukhulisa okuqukethwe kwe-chromium ku-250, njengasesimweni sepayipi lensimbi engagqwali kwenza i-alloy ikhuthazekile emidiya eminingana.
Umkhakha we-teel ukhule emashumini eminyaka ambalwa edlule futhi kunemikhiqizo ehlukahlukene etholakala emakethe. I-ASTM A815 ANX S32750 Amapayipi Fittings angomunye waleyo mikhiqizo futhi ayatholakala ngosayizi ahlukahlukene, amajamo, nobukhulu. I-ASTM A815 ANX S32760 Amapayipi e-Pipe aklanyelwe ukumelana nokugqwala futhi kuthiwa ane-walduall ephelele. Lezi zinhlaka ze-super duplex S32750 Butweld zimelana nokugula ukuguguleka nokukhathala. Bane-misciestructure exubile ka-50% auntenitic no-50% Ferrite.
Ama-fasseners we-Duplex U-ExS32205 asetshenziswa kabanzi ekwakheni nakwezinye izinhlelo zokusebenza zezimboni. Sinikeza lezi zinhlobo zama-fasteners ngobukhulu obungafani kanye nokubekezelela imikhawulo yezinhlobo ezahlukahlukene zezimboni.
I-ASTM A815 Ukucaciswa okuhlanganisa amakilasi amabili ajwayelekile, i-WP no-CR, we-Ferry Ferritic, Ferritic \ Aututenitic, kanye nokugcwaliswa kwensimbi engenasisekelo yokwakhiwa komthungo kanye nokwenziwa. Ukufakwa kwe-WP ye-Class ahlukaniswe ngama-subclass amane: amakilasi WP-S, WP-W, WP-WX-WX, ne-WP-WU. Izinto zokufakelwa ziba nokukhokhiswa, imigoqo, amapuleti, noma imikhiqizo ye-tubular engenamthungo noma ye-welded.
