I-SMLS PIPE

I-Nickel 201 imelana kakhulu nokugqwala ngezixazululo zikasawoti ezingathathi hlangothi kanye ne-alkaline, i-fluorine ne-chlorine, kodwa ukugqwala okukhulu kwenzeka ezixazululweni zikasawoti oxidizing.

I-Nickel 200 iyintengiso emsulwa (99.6%) eholela e-nickel enezakhiwo ezinhle kakhulu zokusebenza kanye nokumelana nokugqwala.

I-alloy 310S Seamless Pipes inokumelana ne-oxidation ku-2000°F. I-ASME SA312 SS 310S Amapayipi Angenamthungo anamandla amaphakathi ezingeni lokushisa eliphezulu. I-UNS S31008 Amapayipi Angenamthungo iyakwazi ukumelana nokugqwala okushisayo. Futhi ebizwa ngokuthi i-WNR 1.4845 Seamless Pipes, inamandla kanye nokuqina emazingeni okushisa e-cryogenic. Yenziwa kalula ngezinqubo ezijwayelekile zezohwebo. Uma kuqhathaniswa ne-carbon steel, lezi zinsimbi ezingenasici ziqinile futhi zivame ukusebenza kanzima ngokushesha.

Amapayipi ensimbi angenamthungo ambozwe ngensimbi eyindilinga, futhi amapayipi ensimbi angenawo amashisela ngaphezulu abizwa ngokuthi amapayipi ensimbi angenamthungo. Ngokwendlela yokukhiqiza, amapayipi ensimbi angenamthungo angahlukaniswa abe amapayipi ensimbi angenamthungo agingqiwe ashisayo, amapayipi ensimbi angenamthungo agoqelwe ngokubanda, amapayipi ensimbi adonswa ngokubanda angenamthungo, amapayipi ensimbi angenamthungo namapayipi aphezulu.

Amapayipi ensimbi angenamthungo anengxenye engenalutho futhi asetshenziswa ngobuningi njengamapayipi okuthutha uketshezi, njengamapayipi okuthutha uwoyela, igesi yemvelo, igesi, amanzi kanye nezinto ezithile eziqinile. Uma kuqhathaniswa nensimbi eqinile njengensimbi eyindilinga, ipayipi lensimbi lilula ngamandla aguquguqukayo kanye ne-torsional futhi iyinsimbi yesigaba esongayo.

Izinhlelo Ezijwayelekile 310\/310S amapayipi ensimbi engagqwali asetshenziswa kuzishisi zebhedi ezimanzi, okhela, amashubhu akhazimulayo, iziphanyeko zamashubhu okucwenga uphethiloli kanye namabhoyela esitimu, izinsimbi zamalahle zangaphakathi, amathangi omthofu, ama-thermowells, amahange aphikisayo, amabhayela avuthayo namakamelo avuthayo, izimbotshana zokushisa umlilo, iziqhumane, iziqhumane, ama-saggars, imishini yokucubungula ukudla, izakhiwo ze-cryogenic.

I-Fusion weldability yohlobo lwe-304l yensimbi engagqwali kuhle kakhulu noma ngaphandle kwama-filler. Induku yokugcwalisa enconyiwe kanye ne-electrode ezosetshenziswa ngensimbi engagqwali engama-304 iyinsimbi engagqwali yebanga lama-308. Ku-304L, ukupakisha okunconyiwe kungu-308L. Izingxenye ezishiselwe kakhulu zingase zidinge ukushiselwa kokuthunyelwe. I-304L ayidingi lesi sinyathelo. Uma ukwelashwa kokushisa kwe-post weld kungenakwenzeka, ibanga lama-321 lingasetshenziswa.

Ipayipi elingagqwali elingu-304L linezakhiwo eziphansi kancane zemishini kunezigaba ezijwayelekile ezingama-304, kodwa lisasetshenziswa kabanzi ngenxa yokuhlukahluka kwalo. Njengensimbi engagqwali ye-Type 304, isetshenziswa kakhulu ekwenzeni ubhiya nokwenza iwayini, kodwa iphinde isetshenziswe ngaphandle kwemboni yokudla, njengeziqukathi zamakhemikhali, izimayini nokwakha. Ilungele izingxenye zensimbi ezifana namantongomane namabhawodi achayeke emanzini anosawoti.

Ipayipi elingenamthungo le-SA335 grade P11 linembe ngokobukhulu ukuze lisetshenziswe ngokunemba, kuyilapho ipayipi elishiselwe linamandla ngokuguga nokuklebhuka okuphezulu.

Amashubhu ahlanganisiwe enza ukufakwa kwamashubhu ubude obude kwenzeke ngaphandle kwesidingo sokuhlanganisa okokufaka. Lokhu kunciphisa isikhathi sokufaka nezindleko kanye nokuqeda amaphuzu avuzayo okungenzeka. Sibeka kokubili amakhoyili wamashubhu angenamthungo nashikelwe ukuze sihlangabezane nezidingo ze-petrochemical, igesi yemvelo ecindezelwe (CNG), i-geothermal, nezinhlelo zokusebenza zokulinganisa ukugeleza. Amashubhu ahlanganisiwe anganikezwa ngobude besigayo eside obunwebeka ngaphezu kwemayela, noma ezigabeni zokusika-ubude ngokwezifiso ezimfishane njengamafidi angamashumi amahlanu.

Lapho ukumelana nokugqwala kubalulekile, insimbi engagqwali iyisinqumo esihle kakhulu sezinto ezibonakalayo. Sinikezela ngeshubhu nepayipi lensimbi engagqwali yokuhweba kukho kokubili ashiselwe futhi angenamthungo, ibha engenalutho, amashubhu okuhlobisa angenasici, ipayipi lensimbi engagqwali, ishubhu ye-Nickel, ipayipi le-Nickel. Iminikelo yethu edume kakhulu amamaki e-austenitic angu-304, 304\/L, 316, kanye no-316\/L amanye amabanga afana no-309, 310, 317L, 321, 347, Alloy 200, 400, 600, 800 ayatholakala uma ecelwa. Izinto ezisetshenziswayo zitholakala ngaphansi kwezimo ezimbalwa, okuhlanganisa okufakwe emanzini kanye nokugcotshwa, okugqamile okufakwe emanzini, ukugaya kuqediwe, nokupholishiwe.

Izakhi ze-alloying ze-A335 nazo zinikeza ukumelana nokugqwala okuphezulu kwipayipi lensimbi. Lokhu futhi kwenza kube ukukhetha kokuqala ezinkampanini zamakhemikhali.

2205 insimbi engagqwali eyi-duplex iyikhambi elibiza izindleko ezinhlelweni eziningi lapho uchungechunge lwama-stainless steels angama-300 lusengozini yokuqhekeka kokugqwala kokucindezeleka kwe-chloride. Ukuqhekeka kokugqwala kwengcindezi kwenzeka lapho izinsimbi ezingenasici zingaphansi kwengcindezi eqinile, ngenkathi zithinta izixazululo eziqukethe ama-chloride. Ukwenyuka kwamazinga okushisa nakho kukhulisa ukuthambekela kwezinsimbi ezingenasici ukuze kugcizelele ukuqhekeka kokugqwala.

Insimbi engagqwali iyingxube yensimbi ekwazi ukumelana nokugqwala. Iqukethe okungenani i-chromium engu-11% futhi ingase iqukathe izakhi ezifana nekhabhoni, ezinye izinto ezingezona ezensimbi nezinsimbi ukuze kutholwe ezinye izici ezifiselekayo. Insimbi engagqwali ukumelana nokugqwala iphuma ku-chromium, eyenza ifilimu ye-passive engavikela izinto ezisetshenziswayo nokuziphilisa lapho kukhona umoya-mpilo.
Isistimu yamapayipi ensimbi engagqwali iwumkhiqizo okhethwayo wokuphatha uketshezi olubolayo noma oluhlanzekile, ama-slurries namagesi, ikakhulukazi lapho kuhileleke ukucindezela okuphezulu, izinga lokushisa eliphezulu noma izindawo ezibolayo. Njengomphumela wezakhiwo zobuhle zensimbi engagqwali, ipayipi livame ukusetshenziswa ekusetshenzisweni kwezakhiwo.

I-Hastelloy tubing ilungele ukusetshenziswa ezimbonini zamakhemikhali, ezemithi, ezolimo, zokudla, ze-petrochemical kanye nezimboni zamandla. Ipayipi le-Hastelloy livame ukucaciswa izinhlelo zokusebenza zezimboni ezigqwala kakhulu futhi kuvame ukusetshenziswa ezinqubweni lapho i-chloride iyingxenye.
