Izinga eliphezulu insimbi engagqwali square tube
I-stainless steel square tube iwuhlobo lwensimbi ende engenalutho. Ngenxa yokuthi lesi sigaba siyisikwele, sibizwa nge-square tube. Inani elikhulu lamapayipi asetshenziselwa ukuthutha uketshezi, okufana nowoyela, igesi yemvelo, amanzi, igesi, umusi, njll. Ngaphezu kwalokho, lapho ukugoba namandla okugoqa kufana, isisindo silula, ngakho-ke nawo abanzi. esetshenziswa ekwenzeni izingxenye zemishini kanye nezakhiwo zobunjiniyela.
Ukuhlukaniswa kwepayipi lesikwele lensimbi engagqwali: ipayipi lesikwele lihlukaniswe ngepayipi lensimbi elingenamthungo kanye nepayipi lensimbi elishiselwe (ipayipi elifakwe). Ngokwesimo sesigaba, singahlukaniswa ngamapayipi angama-square nama-rectangular. Amapayipi ensimbi ayindilinga asetshenziswa kakhulu, kodwa akhona namapayipi ensimbi amise okwesipesheli njenge-semicircular, hexagonal, unxantathu olinganayo kanye ne-octagonal.
Ngepayipi lesikwele lensimbi engagqwali elinomfutho we-fluid, ukuhlolwa kwe-hydraulic kufanele kwenziwe ukuze kuhlolwe ukumelana nengcindezi kanye nekhwalithi. Ifanelekile uma kungekho ukuvuza, ukumanzisa noma ukunwetshwa ngaphansi kwengcindezi ecacisiwe. Amanye amapayipi ensimbi azophinde abe ngaphansi kokuhlolwa kokuqina, ukuhlolwa kokuvutha, ukuhlolwa kokucaba, njll. ngokuya ngokwezinga noma izidingo zomuntu ofuna ngamandla.
Ukucaciswa kweshubhu yesikwele: 5 * 5 ~ 150 * 150 mm ukujiya: 0.4 ~ 6.0 mm
Izinto zeshubhu yesikwele: 304, 304L, TP304, TP316L, 316, 316L, 316Ti, 321, 347h, 310S
Izinsimbi zingasabela nomoya-mpilo emkhathini ukuze zenze ifilimu ye-oxide phezulu. I-iron oxide eyakhiwe ku-carbon steel evamile izoqhubeka ne-oxidize, ikhulise ukugqwala futhi ekugcineni idale izimbobo. Lokhu kungasebenzisa upende noma insimbi ekwazi ukumelana ne-oxidation ukuze kufakwe i-electroplating ukuze kuvikelwe ingaphezulu le-carbon steel, kodwa lesi sendlalelo esivikelayo siyifilimu encane kuphela. Uma ungqimba oluvikelayo lonakalisiwe, insimbi engaphansi izoqala ukugqwala futhi. Ukuthi ipayipi lensimbi engagqwali ligqwalile kuhlobene nokuqukethwe kwe-chromium kunsimbi. Lapho okuqukethwe kwe-chromium ensimbi kufinyelela ku-12%, ungqimba lwe-chromium rich oxide edlulayo futhi eminyene yakheka ebusweni bepayipi lensimbi engagqwali emkhathini ukuze kuvikelwe indawo engaphezulu futhi kuvinjwe ukuphinda kufakwe kabusha. Lesi sendlalelo se-oxide mncane kakhulu. Ngayo, ungabona ukucwebezela kwemvelo kwendawo yensimbi, okwenza insimbi engagqwali ibe nendawo eyingqayizivele. Uma ifilimu ye-chromium yonakele, i-chromium esensimbi nomoya-mpilo osemkhathini kuzovuselela ifilimu ye-passive ukuze iqhubeke 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.
