Ishubhu yesikwele esiphekiwe siwuhlobo lwesigaba esiyisikwele esiyisikwele esinomumo oyisikwele esiphambanayo nosayizi owenziwe ngensimbi yomugqa ogoqelwe oshisayo noma ogoqeke obandayo noma ikhoyili efakwe uthayela njengengenalutho, ngemva kokugoba nokubunjwa okubandayo, bese kuba ukushisela okunemvamisa ephezulu.Ipayipi Lensimbi.Noma ipayipi lensimbi elingenalutho elilungiselelwe ngaphambilini elakhiwe ngendlela ebandayo lingaphansi kokusebenza kokufaka uthayela oshisayo ukuze kutholwe ipayipi lesikwele esinothayela.
Izinsimbi zingasabela nomoya-mpilo emkhathini ukuze zenze ifilimu ye-oxide phezulu.I-iron oxide eyakhiwe ku-carbon steel evamile izoqhubeka ne-oxidize, ukuze ukugqwala kuqhubeke kwanda, futhi ekugcineni kuzokwakhiwa izimbobo.Lokhu kuvikela indawo yensimbi ye-carbon ngokufaka i-electroplating ngopende noma ngensimbi ekwazi ukumelana ne-oxidation, kodwa lolu ngqimba oluyisivikelo luyifilimu encane kuphela, futhi uma ungqimba oluyisivikelo lucekelwa phansi, insimbi engaphansi izoqala ukugqwala futhi.Ukuthi ipayipi lensimbi engagqwali ligqwalile kuhlobene nokuqukethwe kwe-chromium kunsimbi.Lapho okuqukethwe kwe-chromium ensimbi kufinyelela ku-12%, akulula ukugqwala.
Ipayipi eliyisikwele le-hot-dip galvanized: Ipayipi eliyisikwele elenziwe ngepuleti lensimbi noma umucu wensimbi ngemva kokucwiliswa nokushiselwa, futhi ngesisekelo saleli payipi eliyisikwele, ipayipi lesikwele lifakwa echibini lokudonsa amanzi elishisayo ngemva kochungechunge lwamakhemikhali. ukusabela Kwakhiwe ishubhu yesikwele.Inqubo yokukhiqiza yepayipi eliyisikwele elishisayo-dip lilula, ukusebenza kahle kokukhiqiza kuphezulu kakhulu, futhi kunezinhlobonhlobo eziningi kanye nokucaciswa.Lolu hlobo lwepayipi yesikwele ludinga imishini encane kanye nenhloko-dolobha, futhi lufanelekile ukukhiqizwa kwabakhiqizi bamapayipi amancane ayisikwele
Umehluko phakathi kweshubhu lesikwele lensimbi engenamthungo kanye neshubhu lesikwele elishiselwe Insimbi engagqwali iwuhlobo lwensimbi ende engenalutho, ngoba lesi sigaba siyisikwele, sibizwa ngeshubhu lesikwele.Inani elikhulu lamapayipi asetshenziselwa ukuthutha uketshezi, njengamafutha, igesi yemvelo, amanzi, igesi, umusi, njll. Ngaphezu kwalokho, lapho ukugoba namandla okugoqa kufana, isisindo silula, ngakho-ke sisetshenziswa kabanzi. ekwakhiweni kwezingxenye zemishini kanye nezakhiwo zobunjiniyela.Ukuhlukaniswa kwamapayipi: amapayipi ayisikwele ahlukaniswe izigaba ezimbili: amapayipi ensimbi angenamthungo namapayipi ensimbi ashiselwe (amapayipi ahlanganisiwe).Ngokusho kwe-cross-section, ingahlukaniswa ngamapayipi angama-square nama-rectangular.Asetshenziswa kakhulu amapayipi ensimbi ayindilinga, kodwa kukhona namapayipi ensimbi amise okwesipesheli, ane-hexagonal, unxantathu olinganayo, octagonal namanye.
Izinsimbi zingasabela nomoya-mpilo emkhathini ukuze zenze ifilimu ye-oxide phezulu.I-iron oxide eyakhiwe ku-carbon steel evamile izoqhubeka ne-oxidize, ukuze ukugqwala kuqhubeke kwanda, futhi ekugcineni kuzokwakhiwa izimbobo.Lokhu kuvikela indawo yensimbi ye-carbon ngokufaka i-electroplating ngopende noma ngensimbi ekwazi ukumelana ne-oxidation, kodwa lolu ngqimba oluyisivikelo luyifilimu encane kuphela, futhi uma ungqimba oluyisivikelo lucekelwa phansi, insimbi engaphansi izoqala ukugqwala futhi.Ukuthi ipayipi lensimbi engagqwali ligqwalile kuhlobene nokuqukethwe kwe-chromium kunsimbi.Lapho okuqukethwe kwe-chromium ensimbi kufinyelela ku-12%, akulula ukugqwala.
Ipayipi elibandayo eliyisikwele elinesikwele: Umgomo wokugalela amakhaza usetshenziswa epayipini lesikwele elisetshenziselwa ukwenza ipayipi eliyisikwele libe nezinto ezivimbela ukugqwala.Ihluke ekushiseni kwe-dip galvanizing, izimbobo ezibandayo ezifaka ama-galvanizing zisetshenziselwa ikakhulukazi ukulwa nokugqwala ngokusebenzisa izimiso ze-electrochemical.Ngakho-ke, kuyadingeka ukuqinisekisa ukuthi i-zinc powder ihlangene ngokugcwele nensimbi, okuholela ekuhlukeni okungaba khona kwe-electrode, ngakho-ke ukwelashwa kwendawo yensimbi kubaluleke kakhulu.
Amathayili ethusi, amathayela e-aluminium-magnesium-manganese alloy, amathayela ensimbi amatshe anombala, amathayela ensimbi anombala, njll. emakethe ngokuhlangene kubizwa ngokuthi amathayela ensimbi;futhi ipayipi eliyisikwele elinesikwele elishisayo liyipayipi lensimbi elinengxenye yesikwele elingenalutho, elenziwe ngepuleti lensimbi noma ngensimbi.Ngemva kochungechunge lokusabela kwamakhemikhali, kwakhiwa endaweni yokugeza eshisayo e-galvanizing;ingabuye ifakwe emakhazeni ngamapheshana ensimbi agoqelwe ashisayo noma agoqeke abandayo, bese ishiselwa ngefrikhwensi ephezulu.Inqubo yokukhiqiza ilula, ukusebenza kahle kokukhiqiza kuphezulu, izinhlobonhlobo kanye nokucaciswa kuningi, futhi imishini edingekayo incane, kodwa amandla ngokuvamile aphansi kunalawo we-square tube engenamthungo, okuyinzuzo yayo.
I-Stainless Steel Square Tube
Izinzuzo zamapayipi ayisikwele aphehliwe ekwakheni ubunjiniyela
1. Okuhlala isikhathi eside: Ezindaweni ezingaphansi kwedolobha, ubukhulu be-hot-dip galvanized anti-rust bungagcinwa iminyaka engaphezu kwengu-50 ngaphandle kokulungiswa;ezindaweni zasemadolobheni noma ezingasogwini, ungqimba olwakhiwe ngamapulangwe lungagcinwa iminyaka engama-20 ngaphandle kokulungiswa.
2. Ukuthembeka okungcono: Inhlanganisela phakathi kwesendlalelo esinezinsimbi kanye nensimbi iyinhlanganisela ye-metallurgical, ukuze i-zinc ibe yingxenye yensimbi yensimbi, ngakho-ke ukuqina kwe-coating kungcono.
3. Ukuqina okuqinile: Isendlalelo esinezinsimbi sakha isakhiwo esikhethekile se-metallurgical, esingamelana nokulimala komshini ngesikhathi sokuthutha nokusetshenziswa.
4. Zonke izingxenye zeshubhu yesikwele esinezinsimbi zingafakwa uthayela, futhi zingavikelwa ngokugcwele ngisho nasezindaweni ezicindezelayo, emakhoneni abukhali nasezindaweni ezifihliwe.
Ububi: Kuyabiza, kudinga ibhajethi eyanele.Empilweni, lolu hlobo lwe-tile ophahleni luye lwasetshenziswa kabanzi ophahleni oluhlukahlukene, futhi lusetshenziswa kabanzi ekuguquleni ama-pavilions, ama-corridors, izakhiwo zasendulo, amathempeli kanye nophahla oluhlukahlukene.Kulula kakhulu ukucubungula amapayipi esikwele angama-galvanized, kodwa ukusebenza kwamapayipi ngemva kokwakhiwa kuye kwathuthukiswa kakhulu.Kungakhathaliseki ukuthi amandla noma ukuqina, angcono kakhulu kunamapayipi avamile ayisikwele, kanye nokumelana nokugqwala kwemvelo ye-oxidative ekusetshenzisweni kokwakhiwa kobunjiniyela.Ngokuya ngekhwalithi yayo, kulula ukuyibona ngokubukeka.
Ekhaya, ipayipi eliyisikwele likathayela lingasetshenziswa ukwenza imishayo, futhi lingasetshenziswa ukwenza izinsika.Uma une-terrace ekhaya lakho, ufuna ukwenza i-conservatory.Khona-ke kuwumqondo ongcono kakhulu ukukhetha ipayipi yesikwele esinekhwalithi ephezulu.Ngenxa yokuthi kunomswakama omningi ku-greenhouse, noma imuphi umkhiqizo wensimbi wesaba ukugqwala, futhi ipayipi lesikwele eliphehliwe lingaxazulula le nkinga - umphumela wokulwa nokugqwala nokugqwala muhle kakhulu!
Emhlobisoni wobunjiniyela, itshe elomile elilengayo emhlobiso wangaphandle odongeni, ukusekelwa kwephaseji lokwakha, ipayipi eliyisikwele elinothayela lingadlala indima ye-keel yokukhanya, ifreyimu yokusekela, i-anti-corrosion kanye ne-anti-rust, ukubukeka okuhle, nokonga izindleko, kumane kuphelele. ~
Izimo ezisebenzayo emkhathini, kwakheka i-passivation, i-chromium-rich oxide eminyene ebusweni beshubhu lensimbi engagqwali ukuze kuvikelwe indawo engaphezulu futhi kuvinjwe ukuphinda kufakwe i-oxidation.Lolu ungqimba lwe-oxide luncane kakhulu, lapho kubonakala ukucwebezela kwemvelo kwendawo yensimbi, kunikeza insimbi engagqwali indawo eyingqayizivele.Uma ifilimu ye-chromium ibhujiswa, i-chromium esensimbi nomoya-mpilo osemkhathini kuzovuselela ifilimu ye-passive, ezoqhubeka idlala indima yokuvikela.Kwezinye izindawo ezikhethekile, insimbi engagqwali nayo izohluleka ngenxa yokugqwala okuthile kwendawo, kodwa ngokungafani ne-carbon steel, insimbi engagqwali ngeke ihluleke ngenxa yokugqwala okufanayo, ngakho-ke isibonelelo sokugqwala asisho lutho kumapayipi ensimbi engagqwali.
