I-tube eyindilinga ye-Hastelloy C276 ikhiqizwa kusuka ku-alloy ukumelana nokushisa okuphezulu, okunomthelela ekusetshenzisweni kwayo kabanzi embonini yamandla. Nakuba, ipayipi le-Hastelloy C276 libonisa izakhiwo ezivelele ezifana nokumelana nokugqoka okuphezulu, ukumelana nokugqwala nempilo ende yesevisi ngenxa yezinto ezingavuthiwe ezisetshenziswa ekucubunguleni kwayo.

I-Hastelloy Cold Drawn Tubes and Tubes - Inikeza ukusebenza kahle, amandla aphezulu kanye namadigri enkululeko angashintshi uma kuqhathaniswa namashubhu agoqiwe ashisayo nadonswa ngokubanda. Lawa mapayipi asebenza ngokuphumelelayo ngenxa yokuthi i-microstructure yawo ihlale njalo futhi inezakhiwo ezibonakalayo ezikhulayo.

Amapayipi we-Hastelloy C22\/C276 namashubhu akhiqizwa ngokwelashwa ngomshini noma i-electroplating kanye nemishini. Indawo yangaphakathi nengaphandle yeshubhu ye-Hastelloy ipholishelwe ngogesi ukuze kubonakale iyunifomu.

I-Inconel 625 iyingxubevange eyenza kahle emazingeni okushisa aphansi. Ukushintsha kwezinga lokushisa kungabangela ishubhu yengxubevange ukuthi inwebe noma inciphe. Ngakho-ke, izinto ezine-ductility enhle, njengepayipi le-Inconel 625, kufanele zikhethelwe izinhlelo zamapayipi ngokushintshashintsha kwezinga lokushisa, ikakhulukazi ngenxa yezindawo zabo ezinhle.

Ezinye izinhlelo zokusebenza ezijwayelekile ze-Inconel 625 zifaka ukucutshungulwa kwamakhemikhali, ubunjiniyela be-aerospace kanye nolwandle, okokusebenza kokulawula ukungcoliswa kwemvelo kanye neziphehlisi zenuzi. Le nickel alloy inokushisela okuhle kakhulu futhi ivame ukusetshenziselwa ukushisela i-AL-6XN. Le alloy imelana nezinhlobonhlobo zezindawo ezigqwalile, ikakhulukazi ukugqwala kwemigodi kanye nokugqwala kwemifantu.

I-Inconel 625 Clad Pipe iyingxubevange engeke ikwazi ukubola ngenxa ye-oxidation. Le nto ifanele ukwakhiwa kwesakhiwo, ikakhulukazi izakhi ezifana ne-Alloy 625 ishubhu engenamthungo yezinhlelo zokusebenza zokudlulisa ukushisa.

I-Inconel 625 yasungulwa ngeminyaka yawo-1960 ukuze kwakhiwe into engasetshenziswa kumapayipi esitimu. Ezinye izinguquko zenziwe ekwakhiweni kwayo kwasekuqaleni ukuze ikwazi ukumelana ne-creep futhi ikwazi ukushisela.

I-Inconel 625 iyinsimbi ye-austenitic. Lawa mapayipi aklanywe ngekhwalithi ephezulu ye-nickel, i-chromium nokuqanjwa kwe-molybdenum, okwenza amapayipi akwazi ukuthwala uketshezi namagesi kumidiya ebolayo ne-oxidizing.

Ipayipi lensimbi engagqwali iyinsimbi engenalutho nobude, ingxenye yensimbi yokonga iyindilinga. Amapayipi ensimbi engagqwali asetshenziswe kakhulu ku-petroleum, amakhemikhali, ezokwelapha, ekudleni, embonini ekhanyayo, emishini nasezingxenyeni zesakhiwo, njll. Futhi, lapho amandla e-torsional kanye ne-torsional elingana, insimbi engagqwali ilula, ngakho isetshenziselwa izingxenye zemishini kanye nezakhiwo zephrojekthi. Ibuye isetshenziselwe ukukhiqiza imiphongolo namagobolondo ezikhali ezahlukahlukene ezijwayelekile. Lolu hlobo lwepayipi luhlukaniswe: insimbi engagqwali ipayipi nekhono kanye nensimbi engagqwali ashiselwe ipayipi.

I-Inconel 718 tubing iyingxubevange ye-nickel esebenza kahle esetshenziswa ezindaweni zikawoyela omuncu negesi. Ama-alloys asekelwe ku-nickel 718 amashubhu aqinile asuselwa ku-nickel kanye nama-alloys aqinile asekelwe ku-nickel asebenza ngokubandayo anikeza izinzuzo eziningi ezihlanganisa amandla aphezulu, ukuqina, amandla kazibuthe aphansi, kanye nokumelana nokugqwala okuhle kakhulu.

I-Inconel 800, 800H ne-800HT ama-alloys e-nickel-iron-chromium anamandla amangalisayo nokugqwala okuhle nokumelana ne-carburization ekuchayekeni kwezinga lokushisa eliphezulu. Lezi zinhlobo zama-alloys ensimbi ye-nickel ziyafana ngaphandle kokuthi i-alloy engu-800H inokuqukethwe kwekhabhoni ephezulu, futhi cishe u-1.20% we-aluminium ne-titanium kwengezwa ku-800HT ingxubevange.

Amashubhu e-Inconel 718 namanye ama-alloys asekelwe ku-nickel alungele ukwakhiwa okungabizi kakhulu kwamaphampu, ama-valve kanye nemishini yokulawula inqubo ekukhishweni kukawoyela negesi.

Amaalloyi e-nickel aqinisekiswe kabili (800H\/HT) futhi ahlanganisa izinhlobo ezimbili zezakhiwo. I-Incoloy 800H\/HT ingxubevange yakhelwe ukusetshenziswa kwezinga lokushisa eliphezulu kwesakhiwo. Okuqukethwe kwe-nickel kungenza i-alloy imelane kakhulu ne-chloride stress corrosion cracking kanye ne-embrittlement ngokushisa kwesigaba se-sigma. Ukumelana nokugqwala okujwayelekile kuyasiza kakhulu. Ama-alloys 800H kanye ne-800HT anezakhiwo ezinhle kakhulu zokukhasa kanye ne-stress rupture kusimo se-annealed.

I-Inconel 718 iyi-nickel-chromium-molybdenum superalloy eklanyelwe ukumelana nezinhlobonhlobo zezindawo ezigqwala kakhulu, ukugqwala kwemifantu kanye nokugqwala komgodi. Le nickel alloy futhi ikhombisa isivuno esiphezulu kakhulu, izindawo eziqinile kanye nokuqhekeka kwezindawo zokushisa eziphakeme. I-Inconel 718 ihloselwe ukusetshenziswa isikhathi eside ukusuka emazingeni okushisa aphansi ukuya ku-1200¡ãF.

Ikhuluma ngezakhiwo ezijwayelekile ezivezwa amamaki e-Incoloy 800, ipayipi le-Incoloy 800/800H/800HT libonisa ukumelana nokugqwala okuhle kakhulu, ukumelana ne-pitting endaweni ye-chloride, ukumelana nezindawo ezine-acidic ehlukahlukene, ukumelana nokugqwala okuhle okujwayelekile, ukumelana nokugeleza Ukugqwala kwengxube yezinhlamvu nokugqwala, ukumelana nokugqwala kokuqina kanye nokuqina kokugqwala.

I-Inconel 718 Welded Pipe iyingxubevange ye-nickel-chromium-molybdenum eklanyelwe ukumelana nezinhlobonhlobo zezindawo ezigqwala kakhulu, ukugqwala komgodi kanye nokugqwala kwemifantu. Ipayipi le-Inconel 718 EFW iyingxubevange ye-nickel-chromium enemvula eqinile enamandla okuqhekeka okukhuphuka emazingeni okushisa aphakeme afika cishe ku-1300 degrees Fahrenheit (700 degrees Celsius). Ishubhu ye-Inconel 718 ERW inezakhiwo ezinhle kakhulu zemishini emazingeni okushisa aphezulu naphansi.

I-Hastelloy C-276 iyingxubevange ye-nickel-molybdenum equkethe i-chromium. Ipayipi le-Hastelloy C276, i-Hastelloy C276 Seamless Pipe, kanye ne-Hastelloy C276 Seamless Pipe izinto ezikwazi ukumelana nokugqwala futhi zaziwa ngokusetshenziswa kwazo kakhulu ekulahleni amakhemikhali nokulahlwa kukadoti.

I-Hastelloy C276 ishubhu eludongeni elincanyana ijwayele ukusetshenziswa olwandle, i-aerospace, ukucubungula amakhemikhali, ama-reactors enuzi, imishini yokulawula ukungcola, nokunye.

Omunye umehluko phakathi kwe-Astm B626 Nickel Alloy C276 Welded Pipe ne-Alloy C ukuthi ipayipi le-Alloy C276 linokusebenza okungcono.

I-firmware ensomi, eyaziwa nangokuthi izingxenye ezijwayelekile emakethe, yitemu elijwayelekile lohlobo lwezingxenye ezisetshenziswayo ukuxhuma izingxenye ezimbili noma ngaphezulu (noma izingxenye) zibe zizonke. Ibonakala ngezinhlobonhlobo zokucaciswa, ukusebenza okuhlukile nokusetshenziswa, kanye nezinga eliphakeme lokujwayelekile. Ama-fasteners yizingxenye eziyisisekelo ezisetshenziswa kakhulu futhi zidingeka kakhulu.
I-fastener iyisisetshenziswa sezingxenyekazi zekhompuyutha ezihlanganisa ngokuzenzakalelayo noma ezinamathisele

Ukuze udlulise ipayipi, kuyadingeka ukususa ipayipi eliqondile epayipini. Lapho usebenzisa amapayipi ahlukahlukene, amapayipi ahlukahlukene kufanele asetshenziswe. Lapho ipayipi lisetshenziswa, indololwane kufanele isetshenziselwe ukushintsha usayizi wepayipi. Lapho i-bifurcating, ipayipi lezindlela ezintathu Uxhumano lwe-flange olusetshenziswa lapho ijoyinti lisetshenziswa namajoyinti ahlukahlukene wamapayipi, ukuze kufinyelelwe epayipini lokudlulisela elibanga elide, ukuze kufinyelelwe ekunwetshweni okushisayo nokufinyezwa kwejoyinti elibandayo noma ukuxhumana okusebenzayo kokuguga kwepayipi, ukunwetshwa kwebanga elide nokuhlangana okubandayo kusetshenziselwa ukuxhuma ipayipi. , Ekuxhumekeni kwezinsimbi ezihlukahlukene, kukhona nezixhumi namapulaki wesigaba sensimbi.

Amapayipi ensimbi e-A106 angahlakazwa ngesisekelo sokusetshenziswa kwawo. Ukusetshenziswa okujwayelekile kwamapayipi ensimbi kusendaweni yamapayipi amanzi, imigqa yamanzi yezimboni, imigqa yamapayipi kawoyela, ulayini wamapayipi anqamula izwe, ezolimo kanye namapayipi okunisela, imigqa yamashubhu egesi yemvelo, izimboni zamakhemikhali, imboni yezimoto, izimboni zokwakha nezinye izinjongo.
