Ipayipi Lonxande Lensimbi Engagqwali
I-Stainless Steel Square Tube ingenye yezinhlobo zamapayipi.Kunezinhlobo zamapayipi ayindingilizi, ayisikwele, angunxande, ane-hexagonal kanye ne-hydraulic ezinhlobonhlobo zensimbi engagqwali.Kunamabanga angama-304, 316 ezinsimbi ezingenasici ze-austenitic ezisetshenziswa kakhulu ezimbonini.Kukhona nezinye izinhlobo zamapayipi ensimbi engagqwali afana ne-duplex, i-ferritic, i-martensitic kanye ne-alloy steel materials.
Ishubhu lesikwele lensimbi engagqwali kanye neshubhu elingunxande livame ukubizwa ngokuthi yi-tube steel noma ishubhu yesakhiwo.Lokhu kuphinde kubhekiselwe njengengxenye yesakhiwo esingenalutho noma i-HSS ngamafuphi.Isetshenziselwa izinhloso zesakhiwo, ishubhu yesikwele, ishubhu elingunxande, imishayo ye-I, njll., ingathengwa ngezinhlobo eziningi zensimbi nama-alloys.Ukwenziwa kweshubhu yesikwele kuyafana nenqubo yokukhiqiza ipayipi kodwa umkhiqizo uhamba ochungechungeni lwezitendi zokubumba, uhlangabezana nemininingwane yawo yokugcina yesikwele.
Isigaba sesiphambano sesikwele samashubhu sinikeza amandla amahle wejometri.Ngakho-ke amapayipi asetshenziswa ekufakweni kwamandla aphezulu.Kukhona izinsizakalo zokucindezela okukhulu nezinga lokushisa eliphezulu njengezishintshisi zokushisa ezisebenzisa amapayipi.Ishubhu yesikwele esingu-316 ss inamandla futhi imelana nokugqwala.Into engu-316 ine-chromium, i-nickel ne-molybdenum ekubunjweni kwayo.Le nhlanganisela ivumela ukumelana nokugqwala okukhuphukile ngama-215MPa ubuncane besivuno samandla angu-505MPa ubuncane be-tensile amandla.Amashubhu angasebenza futhi ngaphansi kwezinga lokushisa elifinyelela ku-870 degrees Celsius.I-SS Square Welded Tube inamakesi okusetshenziswa kuwoyela negesi, kuphethiloli, kumakhemikhali ephethroli, ezokwakha kanye nasezintweni zesakhiwo.Kukhona amamaki aphezulu njenge-SS317 Square Tubes enziwe ngezinto zebanga le-317 enamandla angu-517MPa ubuncane bokudonsa.Iwusizo ezinhlelweni ezidinga amandla aphezulu.I-ASTM A270 Seamless Square Tube isetshenziswa ngaphansi kwengcindezi ephezulu, izinga lokushisa eliphezulu kanye nezinsiza ezijwayelekile zokugqwala.
I-Stainless Steel Seamless Square Tubing, Inqubo Yokukhiqiza
Ukulungiswa kwensimbi eyindilinga → ukushisa → ukubhoboza okushisayo → ukusika ikhanda → ukucosha → ukupholisha → ukuthambisa → inqubo yokugoqa ebandayo → ukugcoba → ukwelapha okushisayo kwesixazululo → ukuqondisa → ukusika ipayipi → ukucosha → ukuhlolwa komkhiqizo ophelile.
I-Stainless Steel Seamless Square Tubing, Ukuhlaziywa kokusebenza
Insimbi ingasabela nge-oxygen emkhathini ukuze yakhe ifilimu ye-oxide phezulu.I-iron oxide eyakhiwe ku-carbon steel evamile izoqhubeka ne-oxidize, ikhulise ukugqwala futhi ekugcineni yenze izimbobo.Lokhu kungenziwa kusetshenziswa upende noma ucwecwe lwensimbi olumelana ne-oxidation ukuze kuvikelwe ingaphezulu le-carbon steel, kodwa lokhu kunamathela kuyifilimu encane kuphela.Uma ukugqoka konakalisiwe, insimbi engaphansi iqala ukugqwala futhi.Ukuthi ishubhu lensimbi engagqwali ligqwalile yini kuhlobene nokuqukethwe kwe-chromium kunsimbi.Lapho okuqukethwe kwe-chromium ensimbi kufinyelela ku-12%, ingaphezulu leshubhu lensimbi engagqwali likhiqiza ungqimba lwe-passivation kanye ne-chromium eminyene ecebile oksidi ukuze kuvikelwe indawo engaphezulu futhi kuvimbele ukuphinda kufakwe kabusha.Lolu ungqimba lwe-oxide luncane kakhulu, lapho kubonakala khona ukukhanya kwemvelo kwendawo yensimbi, kunikeza insimbi engagqwali indawo eyingqayizivele.Uma ifilimu ye-chromium ilimele kanye, i-chromium esensimbi nomoya-mpilo osemkhathini ukuze kuvuselelwe ifilimu ye-passivation, qhubeka nokudlala indima yokuvikela.Kwezinye izindawo ezikhethekile, insimbi engagqwali nayo izovela okunye ukugqwala nokwehluleka kwendawo, kodwa insimbi engagqwali ne-carbon steel kuhlukile, ngeke kubonakale ukugqwala okufanayo nokwehluleka, ngakho-ke imvume yokugqwala yeshubhu lensimbi engenasici ayinangqondo.
