Isingeniso
Ukuhlola amaqembu okuthengaIbha Yensimbi Engagqwali engu-904LImininingwane, amaphuzu abalulekile ukuqinisekiswa kwebanga, amazinga asebenzayo e-ASTM / EN / UNS, ukwakheka kwamakhemikhali, izakhiwo zemishini, ukusebenza kokugqwala, i-EN 10204 3.1 MTC, ukulandeleka kwenombolo yokushisa, ukuhlolwa kwe-PMI, ukuhlolwa kwe-UT, isimo sobuso, ukubekezelelana kobukhulu kanye nezidingo zokuhlolwa komuntu wesithathu. Ibha yensimbi engagqwali engu-904L, eyaziwa nangokuthi i-UNS N08904 noma i-EN 1.4539, isetshenziswa kakhulu lapho insimbi engagqwali engu-316L inganele ezindaweni zamakhemikhali ezinamandla, i-sulfuric acid, i-chloride equkethe noma zasolwandle, kodwa lapho i-alloy egcwele ye-nickel ingase ingadingeki.
I-904L iyinsimbi engagqwali ye-austenitic ene-alloy ephezulu ene-carbon ephansi, i-nickel ephezulu, i-chromium ephezulu, i-molybdenum kanye nezengezo zethusi. Lokhu kuhlanganiswa kunikeza ukumelana okuthuthukisiwe kokugqwala ekunciphiseni ama-asidi, izindawo ze-chloride kanye nezicelo ezikhethiwe ezihlobene namanzi olwandle. Isetshenziswa kabanzi ezingxenyeni zokucubungula amakhemikhali, ihadiwe yasolwandle, imiphini yokupompa, izingxenye zamavalvu, izinamathiselo, izinduku, izingxenye zomshini, imishini yemithi kanye nezinhlelo zokulawula ukungcola.
Kubathengi bezimboni, ukucacisa "ibha yensimbi engagqwali" akwanele. Umbuzo ophelele webha yensimbi engagqwali engu-904L kufanele ufake ibanga, inombolo ye-UNS, izinga lomkhiqizo, ububanzi, ubude, ukubekezelelana, ubuningi, ukuqeda kwendawo, imfuneko yokuhlola, imfuneko ye-MTC, isikhathi sokupakisha kanye nokulethwa. Lo mhlahlandlela uchaza ukuthi kufanele usebenzise nini ibha yensimbi engagqwali engu-904L, ukuthi ungaqinisekisa kanjani izitifiketi nokuthi ungagwema kanjani amaphutha avamile okuthenga.
Iyini Ibha Yensimbi Engagqwali engu-904L?

Ukuhlolwa kwe-PMI kanye nokuhlolwa komuntu wesithathu kungadingeka kumaphrojekthi abalulekile.
5. Ingabe ibha yensimbi engagqwali engu-904L ingashintshwa?
Yebo. I-904L iyakwazi ukushibilika kahle ngenxa yokuqukethwe kwayo okuphansi kwekhabhoni, kodwa inqubo efanele yokushibilika kanye nezinto zokugcwalisa ezihambisanayo kufanele zisetshenziswe. Kumaphrojekthi amakhemikhali nawasolwandle, ukusebenza kokugqwala ngemva kokushibilika kufanele kucatshangelwe ngokucophelela.
6. Abathengi bangaqinisekisa kanjani izinto zangempela ze-904L?
Abathengi kufanele bahlole i-MTC, inombolo yokushisa, uphawu lomkhiqizo kanye nokwakheka kwamakhemikhali. Ukuhlolwa kwe-PMI kuyanconywa ukuqinisekisa okuqukethwe okuphezulu kwe-nickel, i-molybdenum kanye nethusi, okusiza ukuhlukanisa i-904L ku-316L, 317L kanye nezinye izinhlobo zensimbi engagqwali.
7. Yiluphi ulwazi oludingekayo ukuze uthole ikhotheshini esheshayo?
Umbuzo ophelele kufanele ufake ibanga, izinga elijwayelekile, ububanzi, ubude, ubuningi, ukubekezelelana, ukuqeda ubuso, isidingo sokuhlola, isidingo se-MTC, imbobo yokuya kanye nesidingo sokupakisha. Isibonelo: Ibha eyindilinga yensimbi engagqwali engu-904L, ububanzi obungu-40 mm, ubude obungu-3000 mm, ubuso obuhlutshiwe, ukuhlolwa kwe-EN 10204 3.1 MTC kanye ne-PMI.
Isiphetho
I-904L Stainless Steel Bar iyinto yensimbi engagqwali e-austenitic ene-alloy ephezulu esetshenziswa lapho abathengi bedinga ukumelana nokugqwala okunamandla kune-316L kumaphrojekthi amakhemikhali nawasolwandle. Okuqukethwe kwayo okuphezulu kwe-nickel, i-molybdenum kanye nethusi kuyenza ifanelekele i-sulfuric acid ekhethiwe, i-chloride, i-acid encishisiwe kanye nezindawo zezimboni ezinolaka.
Ukuze kuthengwe ngempumelelo, abathengi kufanele baqinisekise i-UNS N08904, EN 1.4539, ASTM A276 noma i-ASTM A479 ejwayelekile, usayizi webha, ukuqeda kwendawo, EN 10204 3.1 MTC, ukulawula inombolo yokushisa, ukuhlolwa kwe-PMI, ukuhlolwa kwe-UT, ukuhlolwa kobukhulu kanye nokupakishwa kokuthumela ngaphandle. Umhlinzeki wensimbi engagqwali ochwepheshe kufanele asize abathengi baqhathanise i-904L ne-316L, 317L, 2205, 2507, Alloy 20 kanye ne-nickel alloys ngaphambi kokukhetha okokugcina kwezinto.
Ukubizelwa Esenzweni
Xhumana ne-SAKY STEEL ukuthola i-904L Stainless Steel Bar, i-UNS N08904 round bar, ipuleti lensimbi engagqwali elingu-904L, ipayipi, ishubhu, i-flange, izinto zokufakelwa kanye nemikhiqizo yensimbi engagqwali eyenziwe ngokwezifiso. Singasekela i-ASTM A276, i-ASTM A479, i-EN 10088-3, i-EN 10204 3.1 MTC, ukuhlolwa kwe-PMI, ukuhlolwa kwe-UT, osayizi abanziwe ngokwezifiso, ukuqeda kwendawo, ukuhlolwa komuntu wesithathu, ukupakisha kwamanye amazwe kanye nokusekelwa kokulethwa.
Thumela izinga lakho elidingekayo, izinga elijwayelekile, ububanzi, ubude, ubuningi, isimo sobuso kanye nezidingo zesitifiketi eqenjini lethu lobuchwepheshe. Singakusiza uqinisekise imininingwane yebha yensimbi engagqwali engu-904L, siqhathanise amazinga angagqwali angagqwali, sinikeze ikhotheshini futhi sihlele izixazululo ezifanele zokuhlinzekwa kwensimbi engagqwali zephrojekthi yakho yamakhemikhali noma yasolwandle.
