Ipayipi lensimbi elishiselwe ku-Spiral yaziwa nangokuthi ipayipi lensimbi elivunguzayo kanye nepayipi elishiselwe okuvunguza, okuwukusebenzisa insimbi ene-carbon structural steel noma i-low alloy steel strip ngokuya nge-engeli yomugqa ovunguzayo (obizwa ngokuthi i-engeli yokwakha) egoqwe ibe yishubhu, bese ithubhu ashiselwe ndawonye wenza, kungaba ukukhiqizwa strip ewumngcingo enkulu ububanzi steel pipe.Ikhoyili isetshenziselwa ikakhulukazi amapayipi kawoyela negesi, imininingwane yawo OD * ukujiya kodonga.I-Side Welding kanye ne-double side Welding Welding spiral welded pipe kufanele iqinisekise ukuthi ukuhlolwa kwe-hydrostatic, amandla aqinile we-weld kanye nokusebenza kokugoba okubandayo kuyadingeka.
(1)ipayipi elishiselwe uketshezi lwe-pressure elingaphansi kwamanzi: elisetshenziselwa kakhulu ukuthutha uwoyela, ipayipi legesi yemvelo;
(2)i-pressure fluid transmission amapayipi ensimbi ashiselwe imvamisa ephezulu anomthungo ovunguzayo: indlela yokushisela i-high-frequency lap welding ye-pressure fluid transmission spiral high-frequency weld steel pipe.Ikhono lepayipi lensimbi ngaphansi kwengcindezi, ipulasitiki enhle, ukukhululeka kwe-welding kanye nenqubo yokubumba;
(3)ukudluliswa koketshezi olunengcindezi ephansi okuvunguzayo okungaphansi kwe-arc okushiselwe ipayipi lensimbi: ukushisela okuzenzakalelayo kwe-arc okunezinhlangothi ezimbili okuzenzakalelayo noma ukushisela ohlangothini olulodwa ohlelweni lwezomthetho loketshezi olunomfutho ophansi njengamanzi, igesi, umoya nesitimu esinepayipi elishiselwe i-arc elingaphansi.
Izici zomkhiqizo wamapayipi angenamthungo:
1. Ukuhlolwa kokusebenza kwenqubo yeshubhu engenamthungo: ukuhlolwa kokucaba, ukuhlolwa okuqinile, ukuhlolwa komthelela, ukuhlolwa kokuvutha, ukuhlolwa kokuqina, ukuhlolwa kwe-metallographic, ukuhlolwa kokugoba, ukuhlola okungabhubhisi (okuhlanganisa i-eddy yamanje i-X-ray kanye nokuhlolwa kwe-ultrasonic).
2.Ukuhlaziywa kwamakhemikhali epayipi okungenamthungo: ukwakheka kwamakhemikhali wento yokuhlaziya amakhemikhali, ukwakheka kwamakhemikhali ukuze kuhlangatshezwane nezidingo ezijwayelekile.
3. Ukucindezela kwepayipi okungenamthungo kanye nokuhlolwa kwe-hydrostatic okweshubhu yokucindezela ukungena ekuhlolweni kwe-hydrostatic, okungagcini inani lokucindezela elinqunyiwe elingaphansi kwamasekhondi angu-5, ukuze kungavezwa, ukuhlolwa kwengcindezi ye-hydraulic evamile kuyingcindezi engu-2.45MPa Ukuhlolwa kwengcindezi P = 0.5MPAa.
I-4.Isivivinyo sokugqwala: ipayipi lensimbi elimelana nokugqwala kwezimboni ngokwemithethonqubo evamile noma isivumelwano phakathi kokugqwala kokuhlolwa kokumelana nokugqwala kwepayipi lensimbi, akukho ukugqwala kwe-intergranular.
Izici zepayipi elingenamthungo
(1) ububanzi obungaphandle buncane.
(2) Ukunemba okuphezulu kungenza amanani amancane aluhlaza.
(3) ipayipi elibandayo lensimbi elinembayo kanye nekhwalithi enhle yendawo.
(4) ipayipi lensimbi indawo cross iyinkimbinkimbi.
(5) ipayipi lensimbi ukusebenza okusezingeni eliphezulu, metal kuqhathaniswa aminyene.
