347/347H Insimbi Engagqwali

347 insimbi engagqwali ishidi, 347 insimbi engagqwali, TP 347H steel tubing

I-alloy 347 kanye ne-347H iwuhlobo lwensimbi engagqwali ye-Niobium Stabilized Austenitic ephezulu kanye nokwengezwa kwe-Niobium. Ukwengezwa kwe-elementi Nb, kwenza i-TP347H ibe nokugqwala okuhle kwe-intercrystalline, ikakhulukazi emithonjeni eyonakalisayo efana ne-asidi, i-alkali, nosawoti. Isetshenziswa kabanzi kuma-heaters, amapayipi we-superheater, amapayipi okushisa kabusha, ipayipi le-steam kuma-boilers okukhiqiza amandla, i-petroleum, imboni yamakhemikhali, i-synthetic fiber, ukudla kanye nemboni yephepha. I-elementi ye-Nb isengozini encane ekulahlekeni okushisayo kune-Ti, ngakho-ke ingasetshenziswa njengenduku yokushisela ye-Cr-Ni Austenitic steel stainless steel. Ngokufanayo ne-18-8 Austenitic stainless steel equkethe i-Ti, iBanga 347H linamandla aphezulu ezinga lokushisa eliphezulu kanye nokumelana ne-oxidation okungcono kunensimbi engagqwali engu-316.

Izicelo:

Ingxubevange engu-347 kanye no-347H ngokuvamile isetshenziswa lapho kudingeka khona izimo ezigqwalile ezifana nepayipi le-superheater, ipayipi le-reheater, ipayipi lesitimu kubhayela omkhulu nesishintshi sokushisa, kanye nezindawo zokuhluza uwoyela ukuze kucutshungulwe i-petrochemical.

I-LKALLOY ingumnikezeli ohamba phambili embonini wochungechunge lwe-Cr-Ni namanye ama-alloys ensimbi engagqwali ekhwalithi ephezulu. I-LKALLOY ihlinzeka ngepayipi lensimbi engagqwali engu-347H kanye neshubhu, nezinduku zokugcwalisa ezingama-347 ezisetshenziselwa izinhlelo eziningi ezifana nama-condenser, izishintshisi zokushisa, izihlungi, nokunye.
