Ukubukelwa kwepayipi kungenye yamakhono ethu ayisisekelo.

I-Hastelloy iyinhlangano ye-nickel engamelana ne-cororion equkethe ezinye izinto zamakhemikhali ezifana ne-chromium ne-molybdenum. Lokhu okuqukethwe kunokumelana okuphezulu kokushisa kanye nokuphikiswa okuhle kakhulu kokugqwala. I-Hastelloy C276 ingenye yamabanga aseHastelloy asetshenziswa embonini kawoyela negesi.

I-Incons 718 isibe wusizo ezinhlobonhlobo zezicelo ezisukela ekusebenzeni kokukhiqiza emishini yezempi kanye nemboni ye-aerospace.

Ukuhlaselwa okuncane noma okungekho kwenzeka egumbini futhi kuphakame amazinga okushisa kumagesi owomile, njenge-chlorine noma i-hydrogen chloride. Emazingeni okushisa aze afike ku-550c kule mithombo yezindaba, le alloy ikhonjiswe ukuthi ingenye ye-alloys ejwayelekile.

I-ASTM A312 TP 316L amapayipi okushisa anama-flanges

Okwezinhlelo ezithile, ibanga le-grade 254 SMO kubikwe ukuthi libambela imali esebenza ngempumelelo ye-Nickel neTitanium Alloys.

I-Hastelloy C276 yaziwa ngokumelana kwayo okuhle kakhulu kokugqwala kwemidiya ehlukahlukene. Kubandakanya i-chloride ion, amakhompiyutha esibabule, njll. Ngaphezu kwalokho, le alloy inokumelana kahle nokugqwala kwama-crevice, ukugqwala okukhonkotha kanye nokuqhekeka kokugqwala kwengcindezi. Kuyasiza ukumelana nemiphumela elonakalisayo ye-chlorine emanzi, i-chlorine dioxide ne-hypochlorite. Lo mkhiqizo ulungele izinhlelo zokusebenza zamanzi olwandle.

I-Alloy 254 SMO ukuphela okuphezulu, i-molybdenum ne-nitrogen allOred Super Auntenitic insimbi engenacala ngokuqukethwe okuphansi kwekhabhoni.

I-Steel yensimbi esetshenzisiwe njengegama ngokwalo imisindo, yenziwa ngensimbi yangaphambi kwezobuciko. Ukwakheka kwenziwa endaweni elawulwayo ngaphakathi kwefektri bese kuthunyelwa endaweni yamakhasimende e-ASPOLD.

Ukubambisana kuwumkhuba wezinto zokubutha zesakhiwo endaweni yokusebenzela noma esinye indawo yomhlangano ngaphambi kokuhambisa esizeni ukuze kusizakale ukwakhiwa.

I-Plasma Arc Cutter isetshenziselwa amapayipi amakhulu (ngenhla kwama-intshi angama-28 wosayizi wepayipi oyisikhonkwane) nokusetshenziswa kwayo nakho kuzuzisa ukusika amagatsha. Uma kungenzeka, icala langaphakathi kumele libe ngamapayipi noma ukufakwa, ukuze livikeleke eziswindi ezidalwe yi-plasma arc cutter. Ngemuva kokusika, nokulungiselela onqenqemeni kumele kugcinwe.

Lesi sigaxa sepayipi esingenasici sivame ukuthathwa ukuze sikwazi ukwenza ukuxhumana kwamanye ama-spools futhi sithanda kakhulu ezisetshenziselwa izimboni ezahlukahlukene ezinjengezitshalo zamandla kanye nokuhlaziywa kukaphethiloli zidinga amapayipi afudumele.

Lezi zinenzuzo ye-nickel kanye ne-molybdenum enikeza ukumelana nezimo ezinciphisa kakhulu. Ukumelana ne-oxidation kuphakame kakhulu kulezi zinto zokwakha ngenxa yokungezwa kokuqukethwe kwe-chromium.

I-Monel K500 iyinhlangano ye-nickel-Copper Alloy ehlanganisa isimilo esihle kakhulu sokulwa nokugqwala kwe-monel 400 ngenzuzo eyengeziwe yamandla amakhulu nobulukhuni.

Izidingo zeklayenti¡. Futhi singanikeza okususwayo kokusebenza okuqukethwe okuqukethwe okuqukethwe, kufaka phakathi amamojula wokusika amapayipi, ukubheja, ukuhlangana futhi

Ama-tee we-welded we-socket abuye enza i-perpendicular angle phakathi kwemigqa exhunyiwe. Basebenzise izinhlelo zokusebenza ezicindezela kakhulu. Ngokuphikisana neTett Welded Tees, ama-selded telded asetshenziswa kuzinhlelo zokusebenza lapho i-radius yamapayipi ngokuvamile incane. Ama-Tees we-Socket Welded awadingi inqubo ebukekayo ngaphambi kokufudumala. Ngakho-ke, lezi zinhlobo zamashumi amakhethini zithandeka kwezinye izinhlelo zokusebenza lapho amagatsha egatsha kufanele agcinwe ngendlela efanayo ngaphambi nangemva kokushiswa.

I-316l, nokho, ukukhetha okungcono kwephrojekthi edinga ukufudumala okuningi ngoba i-316 itholakala kalula ekuwohlokeni kwamandla ku-316L (ukugqwala ngaphakathi kweWeld).

Inani lama-welds ku-spool kumele ligcinwe ukubala okuncane. Ubukhulu besikhala phakathi kwezindawo eziphakathi nendawo kanye nemigqa yesikhungo akumele ibe mikhulu kuneziphindwe kane udonga lwepayipi noma efanele. Ngemuva kwama-welds amakhulu, ama-tacks welds kumele enziwe ngokunembile. Zonke ama-welds e-spools kumele zisetshenziswe ngokuya ngokucaciswa kwenqubo ye-welding efanele (i-WPS). Ngemuva kokuthi inqubo ye-welding yenziwe, ukulawulwa kwekhwalithi kwezakhi kwenziwa ngochwepheshe.

I-Plasma Arc Cutter isetshenziselwa amapayipi amakhulu (ngenhla kwama-intshi angama-28 wosayizi wepayipi oyisikhonkwane) nokusetshenziswa kwayo nakho kuzuzisa ukusika amagatsha. Uma kungenzeka, icala langaphakathi kumele libe ngamapayipi noma ukufakwa, ukuze livikeleke eziswindi ezidalwe yi-plasma arc cutter. Ngemuva kokusika, nokulungiselela onqenqemeni kumele kugcinwe.

I-Hastelloy C276 ingenye yama-alloys ambalwa amelana ne-wet chloride gesi, i-hypochlori ne-chlorine dioxide solutions.

Zisetshenziselwa insiza yokushisa ephezulu, lapho kudingeka khona i-oxidation kanye ne-carburburation. Ngezakhiwo ezinhle kakhulu zokucindezela kwengcindezi, noma insiza yomkhumbi yengcindezi engenhla kwe-815¡Ãc, incoloy 800h noma incoloy 800ht kufanele isetshenziswe.

I-Chromium, i-molybdenum ne-nitrogen kukhulisa ukumelana nokugqwala okukhonkotha. I-nickel ifaka isakhiwo se-auntenitic.

Amapayipi angama-304l anama-Flanges Butt Weld Tee kanye ne-Elbows - Zhengzhou Huitong Pipeline Equipment Co, Ltd.

Alloy 347 (uns s34700) nguColumbium waqinisa ipuleti yensimbi engenacala engenacala ngokumelana kahle nokuphikiswa okujwayelekile kanye nokuphikiswa okungcono ezimweni eziqinile ze-oxidizing eziqinile kune-321 (uns s32100).

I-Incoloy Alloy 800 isetshenziswa kabanzi kumishini okufanele ibe namandla aphezulu kanye nokumelana ne-oxidation, i-carburation neminye imiphumela elimazayo yokuvezwa kokushisa okuphezulu.

Amabanga amabili ajwayelekile ensimbi ajwayelekile angama-304 no-316. Umehluko omkhulu ukufakwa kwe-molybdenum, i-alloy ethuthukisa kakhulu ukumelana nokukhulisa, ikakhulukazi ezindaweni ezinosawoti noma nge-chloride.

I-Hastelloy C276 2.4819 Izinhlelo zokupheka zamapayipi ezilungele izinhlelo eziningi zezinqubo zamakhemikhali

I-Chromium yi-ejenti eyinhloko yokuhambisa ukumelana nokugqwala ezindaweni ezingathathi hlangothi noma ezi-oxidizing.

Ezinye izindawo ezithandwayo ze-nickel-chromium ziseminyakeni evulwe ngokwanele ngokungezwa kwe-aluminium ne-titanium.

Amapayipi spools yizingxenye zangaphambi kokwakha kohlelo lwamapayipi. Amapayipi, ama-flanges, kanye nokufakelwa abizwa ngokuthi ama-Pipe Spools futhi akhiqizwa ngaphambi kokuthi asetshenziswe ohlelweni lwamapayipi.
