Ake siqale ngeqiniso:
Amapayipi ensimbi engagqwali asetshenziswa kakhulu ezindaweni ezahlukahlukene ezilonakalisayo. Kodwa-ke, uma uqaphela, uzothola ukuthi kumadokhumenti e-Design athile amayunithi, inqobo nje i-DN≤40, zonke izinhlobo zezinto zokwakha zamukelwa ngokuyisisekelo. Kumadokhumenti okuklanywa kwamanye amayunithi, amapayipi ensimbi engagqwali, noma ngabe amakhambi athi, asebenzisa futhi amapayipi e-butt-welded esikhundleni se-tube fittings.
Njengoba isisho siqhubeka: ukuze siqinisekise ikhwalithi ye-welding yamapayipi amancane futhi gwema ukungena kwe-welding ngesikhathi sokushiswa kwamanje, ukuxhumana kwesokhethi kuvame ukusetshenziswa uxhumano lwe-butt welding. Ngakho-ke, kungani amanye amayunithi ensimbi engenasici ama-caliber amancane amapayipi ama-caliber awathwali izingcezu ze-incubation? Lokhu kubandakanya inkinga: ukugqwala kwe-crevice.
Ake sixoxe ngokuthi yikuphi ukugqwala kwe-crevice?
Lapho kukhona igebe (ngokuvamile 0.025-0.1mm) ngaphezulu kwezakhi zensimbi ngenxa yezinto zakwamanye amazwe noma izizathu ezakhayo, kunzima ukuthutha okuphakathi kwe-corlosive kugebe, okuholela ekugcekeni kwensimbi, okubizwa ngokuthi ukugqwala kwensimbi. Ukugqwala kwe-crevice kuvame ukuba yisikhuthazo sokuncipha kwamanye ukugqwala (njengokugqwala okukhohlisayo, ukugqwala kwengcindezi), ngakho-ke iphrojekthi ilwela ukugwema ukuvela kokugqwala kwe-crevice. Ukuba khona kwemifantu kufanele kugwenywe ekwakhiweni kwesakhiwo samapayipi se-medium ethambekele ekugcekeni.
Insimbi engagqwali engama-304 flange
Kungenxa yokuthi kukhona igebe ekuxhumaneni kwesokhethi, ngakho-ke amanye amayunithi ukuze agweme ukugqwala kwegebe, ngokuba khona kwe-corrosion yamapayipi ensimbi engagqwali, ipayipi elincane le-caliber livame ukusebenzisa i-butt welding uxhumano, i-welding inqubo yokulawula ukuqinisekisa ikhwalithi, gwema ukusetshenziswa kokuqonda.
I-304 yensimbi engasenzi, isetshenziswa kabanzi ekukhiqizweni kwemishini nezingxenye ezidinga ukusebenza okuhle okuhle (ukumelana nokugqwala kanye nokwakhiwa).
I-304 Insimbi Engagqwali inguhlobo lwensimbi engagqwali ekhiqizwa ngokuya ngamazinga we-ASTM e-United States. I-304 ilingana neChina 0Cr19NI9 (0CR18NI9) insimbi engenacala. I-304 iqukethe i-19% chromium ne-9% nickel.
I-304 iyinsimbi esetshenziswa kabanzi, insimbi engamelana nokushisa. Isetshenziswa emishini yokukhiqiza ukudla, imishini yamakhemikhali ye-Xitong, amandla enuzi, njll.
I-304 insimbi engagqwali ye-butt welding flangeIngabe i-chromium esetshenziswa kabanzi - insimbi engenasisekelo ye-nickel, ngokumelana kahle nokuqina, ukumelana nokushisa, amandla okushisa aphansi kanye nezakhiwo zemishini. Ukuphikiswa kokugqwala emkhathini, uma kuwukuvela kwezimboni noma indawo engcoliswe kakhulu, kudingeka ihlanzwe ngesikhathi ukugwema ukugcwala. Ilungele ukucutshungulwa kokudla, ukugcinwa nokuhamba. Inemishini emihle nokushiswa. I-Plate Heat Exchanger, ama-Bellows, izimpahla zasendlini, izinto zokwakha, amakhemikhali, imboni yokudla, njll.
