Ipayipi elivunguzayoiyipayipi lensimbi elivunguzayo elenziwe ngekhoyili yensimbi eyi-strip njengempahla eluhlaza, ekhishwa ngezinga lokushisa elivamile, futhi eshiselwe inqubo yokushisela engaphansi kwe-arc enezintambo ezimbili emaceleni ezenzakalelayo. Ipayipi lensimbi elivunguzayo liphakela umucu wensimbi kuyunithi yepayipi elishiselwe. Ngemva kokugoqwa ngama-rollers amaningi, insimbi ye-strip igoqwa kancane kancane ukuze yakhe i-circular tube billet enegebe lokuvula. Lungisa ukuncishiswa kwerola ye-extrusion ukuze ulawule igebe lomthungo wokushisela libe ngu-1~3mm futhi wenze iziphetho ezimbili zejoyinti le-weld ziguqe.

I-Spiral pipe material:
Q235A, Q235B, 10#, 20#, Q345 (16Mn),
L245(B), L290(X42), L320(X46), L360(X52), L390(X56), L415(X60), L450(X65), L485(X70), L555(X80)

L290NB/MB(X42N/M), L360NB/MB(X52N/M), L390NB/MB(X56N/M), L415NB/MB(X60N/M), L450MB(X65), L485MB(X70), L555MB(X80) .

Inqubo yokukhiqiza ipayipi elivunguzayo:

(1) Izinto ezisetshenziswayo amakhoyili ensimbi ehlutshiwe, izintambo zokushisela, nama-fluxes. Ngaphambi kokuba zisetshenziswe, kufanele zihlolwe ngokuqinile ngokomzimba namakhemikhali.
(2) I-head-to-tail joint butt ye-strip steel ithatha i-arc welding enocingo olulodwa noma izintambo ezimbili ezingaphansi kwamanzi, futhi i-arc engaphansi kwamanzi isetshenziselwa ukulungisa ukushisela ngemva kokugoqwa emapayipini ensimbi.
(3) Ngaphambi kokwakhiwa, insimbi ye-strip iyalinganiswa, inqunywe, ihlelwe, ihlanzwe, ihanjiswe futhi igotshwe ngaphambili.
(4) Izikali zokucindezela kokuxhumana ngogesi zisetshenziselwa ukulawula ukucindezela kwamasilinda nhlangothi zombili zesithumeli sokuhambisa ukuze kuqinisekiswe ukudluliswa kahle komugqa.
(5) Yamukela isilawuli sangaphandle noma ukwakhiwa komqulu wokulawula wangaphakathi.
(6) Idivayisi yokulawula igebe lokushisela isetshenziselwa ukuqinisekisa ukuthi igebe lokushisela lihlangabezana nezidingo zokushisela, futhi ububanzi bepayipi, ukungahambi kahle kanye negebe lokushisela kulawulwa ngokuqinile.
(7) Kokubili i-welding yangaphakathi ne-welding yangaphandle isebenzisa umshini wokushisela we-American Lincoln wocingo olulodwa noma i-double-wire submerged arc welding, ukuze kutholwe izinga lokushisela elizinzile.
(8) Wonke ama-seam ashiselwe ahlolwa umtshina we-inthanethi oqhubekayo we-ultrasonic othomathikhi, oqinisekisa ukumbozwa kokuhlola okungabhubhisi okungu-100% kwama-spiral weld. Uma kunesici, kuzokwethusa ngokuzenzakalelayo futhi kufafaze uphawu, futhi izisebenzi zokukhiqiza zingalungisa imingcele yenqubo nganoma yisiphi isikhathi ngokusho kwalokhu ukuze kuqedwe iphutha ngesikhathi.
(9) Sebenzisa umshini wokusika i-plasma yomoya ukuze usike ipayipi lensimbi libe yizicucu eyodwa.
(10) Ngemva kokusika amapayipi ensimbi eyodwa, iqoqo ngalinye lamapayipi ensimbi kufanele ahlolwe kuqala ukuze ahlole izakhiwo zemishini, ukwakheka kwamakhemikhali, isimo sokuhlangana kwamapayipi okushisela, izinga eliphezulu lepayipi lensimbi kanye nokuhlolwa okungacekeleki phansi ukuze kuqinisekiswe ukuthi inqubo yokwenza amapayipi ifanelekile ngaphambi kokuthi ifakwe ngokusemthethweni ekukhiqizeni.
11 Uma kuneziphambeko ngempela, ngemva kokulungiswa, zizophinde zihlolwe ngokungekonakali kuze kube yilapho kuqinisekiswa ukuthi iziphambeko zizoqedwa.
(12) Amashubhu lapho i-strip steel butt eshisela khona kanye namajoyinti e-D ahlangana nama-spiral weld ahlolwa nge-X-ray TV noma ifilimu.
(13) Ipayipi ngalinye lensimbi liye lahlolwa ingcindezi ye-hydrostatic, futhi ingcindezi ivalwe nge-radially. Ingcindezi yokuhlola kanye nesikhathi kulawulwa ngokuqinile ipayipi lensimbi lokutholwa kwamanzi okucindezela i-microcomputer idivayisi. Imingcele yokuhlola iphrintwa futhi irekhodwe ngokuzenzakalelayo.
(14) Isiphetho sepayipi senziwa ngomshini ukuze kulawulwe ngokunembile ukuma kobuso bokuphela, i-engeli ye-bevel kanye nonqenqema olubuthuntu.

Izici eziyinhloko zenqubo yepayipi elivunguzayo:

a. Phakathi nenqubo yokwenza, ukuguqulwa kwepuleti yensimbi kufana, ukucindezeleka okusalayo kuncane, futhi ubuso abukhiqizi imihuzuko. Ipayipi lensimbi elivunguzayo elicutshunguliwe linokuguquguquka okukhulu kusayizi nobubanzi bemininingwane yobubanzi nokuqina kodonga, ikakhulukazi ekukhiqizeni amapayipi anezindonga eziwugqinsi wezinga eliphezulu, ikakhulukazi amapayipi anodonga oluwugqinsi olunobubanzi obumaphakathi.
b. Ukusebenzisa ubuchwepheshe bokushisela be-arc obunezinhlangothi ezimbili obusezingeni eliphezulu, ukushisela kungenziwa endaweni engcono kakhulu, futhi akulula ukuba namaphutha njengokungahambi kahle, ukuchezuka kwe-welding kanye nokungena okungaphelele, futhi kulula ukulawula ikhwalithi yokushisela.
c. Yenza ukuhlolwa kwekhwalithi engu-100% yamapayipi ensimbi, ukuze yonke inqubo yokukhiqizwa kwamapayipi ensimbi ibe ngaphansi kokuhlolwa okusebenzayo nokuqapha, ukuqinisekisa ngempumelelo ikhwalithi yomkhiqizo.
d. Zonke izinto zokusebenza zomugqa wonke wokukhiqiza zinomsebenzi wokuxhumana nohlelo lokutholwa kwedatha yekhompiyutha ukuze kubonakale ukudluliswa kwedatha yesikhathi sangempela, futhi imingcele yezobuchwepheshe enqubweni yokukhiqiza ihlolwe yigumbi lokulawula eliphakathi.

Izimiso zokunqwabelanisa zamapayipi avunguzayo zidinga:
1. Imfuneko yomgomo yokupakishwa kwamapayipi ensimbi okuvunguzayo ukupakisha ngokuya ngezinhlobonhlobo kanye nokucaciswa ngaphansi kwesisekelo sokupakisha okuzinzile nokuqinisekisa ukuphepha. Izinhlobo ezahlukene zezinto kufanele zipakishwe ngokwehlukana ukuze kuvinjelwe ukudideka nokuguguleka komhlabathi;
2. Akuvunyelwe ukugcina izinto ezigqwalisa insimbi ezungeze isitaki samapayipi ensimbi;
3. Iphansi lenqwaba yepayipi lensimbi ezungezayo kufanele libe phezulu, liqine futhi liyisicaba ukuze kuvinjelwe ukuthi impahla ingabi manzi noma ikhubazekile;
4. Impahla efanayo ipakishwe ngokwehlukana ngokuya nge-oda lokugcinwa;
5. Ezingxenyeni zepayipi lensimbi elivunguzayo elibekwe endaweni evulekile, kufanele kube namaphedi okhuni noma amapheshana amatshe ngaphansi, futhi indawo yokupakisha ithambekele kancane ukuze kube lula ukugeleza kwamanzi, futhi kufanele kukhokhwe ekubekeni izinto eziqondile ukuvimbela ukuguquguquka kokugoba;
6. Ubude bokunqwabelana kwamapayipi ensimbi ezungezayo akumele kweqe ku-1.2m ngomsebenzi wezandla, u-1.5m womsebenzi wemishini, futhi ububanzi besitaki akumele budlule ku-2.5m;
7. Kufanele kube nomgudu othile phakathi kwezitaki. Ishaneli yokuhlola ngokuvamile iyi-0.5m, kanti isiteshi sokufinyelela sincike kusayizi wempahla kanye nemishini yokuthutha, ngokuvamile eyi-1.5-2.0m;
8. Insimbi ye-engeli kanye nensimbi yesiteshi kufanele kupakishwe emoyeni ovulekile, okungukuthi, umlomo kufanele ubheke phansi, futhi i-I-beam kufanele ibekwe ngokuqondile. I-I-channel surface yensimbi akufanele ibheke phezulu, ukuze igweme ukunqwabelana kwamanzi nokugqwala;

9. Iphansi lesitaki liphakanyisiwe. Uma inqolobane iphansi kukakhonkolo libalele, inganyuswa ngo-0.1m; uma ingaphansi kodaka, kufanele iphakanyiswe ngo-0.2-0.5m. Uma kuyindawo evulekile, phansi kukakhonkolo kufanele kukhushulwe ngobude obungu-0.3-0.5m, futhi indawo yesihlabathi nodaka kufanele ikhuliswe ngobude obungu-0.5-0.7m.
