4. 254SMO Incazelo:
a. I-254SMO iyinsimbi engagqwali ye-austenitic. Ngenxa yokuqukethwe kwayo okuphezulu kwe-molybdenum, inokumelana okuphezulu kakhulu nokubola
nokugqwala kwemifantu.
b. Lolu hlobo lwensimbi engagqwali luthuthukiswa ukuze lusetshenziswe ezindaweni eziqukethe ama-halides njengamanzi olwandle. I-254SMO nayo inokuhle
ukumelana nokugqwala okufanayo.
c. Ikakhulukazi ku-asidi equkethe i-halide, insimbi iphakeme kunensimbi engagqwali evamile. Okuqukethwe kwayo kwe-C kungu-<0.03%, ngakho kubizwa
i-pure austenitic stainless steel (<0.01% ibizwa nangokuthi i-super austenitic stainless steel). Insimbi engagqwali iwuhlobo lwensimbi ekhethekile engagqwali.
d. Okokuqala, ihlukile kunensimbi engagqwali evamile ekwakhiweni kwamakhemikhali. Kubhekiselwa ohlotsheni lwensimbi engagqwali esezingeni eliphezulu
equkethe i-nickel ephezulu, i-chromium ephezulu ne-molybdenum ephezulu. Edume kakhulu i-254SMo equkethe u-6% Mo. Lolu hlobo lwensimbi
inokumelana nokugqwala okuhle kwendawo.
e. Inokumelana nokugqwala okuhle kwe-pitting (PI ≥ 40) kanye nokumelana nokugqwala kwengcindezi ngaphansi kwezimo zamanzi olwandle, i-aeration, i-crevice.
nokuhlikihla ngesivinini esiphansi.
f. Iyingxenye ye-Ni base alloy ne-titanium alloy. Okwesibili, mayelana nokumelana nokushisa okuphezulu noma ukumelana nokugqwala,
inokumelana nezinga lokushisa eliphezulu okuhle kakhulu noma ukumelana nokugqwala, okungenakufakelwa indawo ku-304 steel stainless. Ngaphezu kwalokho,
kusukela ekuhlukaniseni insimbi engagqwali, isakhiwo se-metallographic sensimbi engagqwali ekhethekile iyisakhiwo esiqinile se-austenitic metallographic.
g. Njengoba le nsimbi ekhethekile engagqwali iyi-alloy material ephezulu, inqubo yayo yokukhiqiza iyinkimbinkimbi impela. Ngokuvamile, abantu bangathembela kuphela
izinqubo zendabuko zokukhiqiza le nsimbi ekhethekile engagqwali, njengokuthela, ukufoja, ukugingqa, njll.
5. Isicelo:
1) Izilwandle: izakhiwo zasolwandle zemvelo yasolwandle, ukuchithwa kwamanzi olwandle usawoti, i-mariculture, ukushintshaniswa kokushisa kwamanzi olwandle, njll.
I-2) Ukuvikelwa kwemvelo: idivayisi ye-flue gas desulfurization yokukhiqiza amandla ashisayo, ukwelashwa kwamanzi angcolile, njll.
3) Amandla: ukukhiqizwa kwamandla e-athomu, ukusetshenziswa okuphelele kwamalahle, ukukhiqizwa kwamandla olwandle, njll.
4) Imboni ye-petrochemical: ukucwenga uwoyela, imishini yamakhemikhali, njll.
5) Inkambu yokudla: ukwenza usawoti, ukuphisa usoso wesosi, njll.
I-6) Imvelo ye-chloride yokuhlushwa ephezulu: imboni yephepha, amadivaysi ahlukahlukene wokuxubha.
6. Ukwelashwa okwengeziwe:
1) IsiPolish
2) Ukumaka:
3) Ukupakisha:
7. Ukulayishwa Kwesitsha:
Izithombe zemininingwane yomkhiqizo:
Umhlahlandlela Womkhiqizo Ohlobene:
Sinemishini ethuthukisiwe. Imikhiqizo yethu ithunyelwa e-USA, UK njalo njalo, ijabulela idumela elihle phakathi kwamakhasimende esitayela sase-Europe se-1.75 Stainless Steel Pipe - 254SMO UNS S31254 1.4547 ipayipi elingenamthungo - Huaxin, Umkhiqizo uzohlinzeka emhlabeni wonke, onjalo njenge: Spain, European, Australia, Uma noma yimuphi umkhiqizo uhlangabezana nesidingo sakho, khumbula uzizwe ukhululekile ukuxhumana nathi. Siyaqiniseka ukuthi noma imuphi umbuzo noma imfuneko yakho izothola ukunakwa ngokushesha, okuthengiswayo kwekhwalithi ephezulu, amanani akhethekile kanye nempahla eshibhile. Bamukele ngobuqotho abangani emhlabeni wonke ukuthi bashayele noma beze ukuzovakasha, ukuze nixoxe ngokubambisana ngekusasa elingcono!
