Mtengo wa LSAWamatengera ukadaulo wowotcherera wa arc, pogwiritsa ntchito kuwotcherera kwa filler, chitetezo cha tinthu chokwiriridwa arc.
LSAW ndiye chidule cha Chingerezi cha chitoliro chachitsulo chomizidwa pansi pamadzi.Kapangidwe ka mipiringidzo yazitsulo yomizidwa ndi arc yowotcherera yowongoka yachitsulo imaphatikizapo ukadaulo wopanga JCOE, ukadaulo wopangira ma arc wothira pansi ndi ukadaulo wopanga UOE.
Njira yopangira Pipe ya Longitudinal Submerged-arc Welded(LSAW) ili motere:
Akupanga mbale kufufuza → m'mphepete mphero → chisanadze kupinda → kupanga → Pre-kuwotcherera → kuwotcherera mkati → kuwotcherera kunja → Akupanga kuyendera → X-ray anayendera → Kukulitsa → hydraulic mayeso →l.Chamfering → Akupanga kuyendera → X-ray anayendera → maginito tinthu anayendera pa chubu mapeto

Kuyeza kwa Hydrostatic
Kuyesa kwa NDT (RT).
Kuyesa kwa NDT (UT).
Kupindika Mayeso-utali wokwanira wa chitoliro uyenera kuyima kukhala wopindika kupyola 90 ° kuzungulira cylindrical mandrel.
Mayeso a Flattening -ngakhale kuyezetsa sikofunikira, chitolirocho chizitha kukwaniritsa zofunikira zoyeserera.
Kuyesa kwa Hydrostatic-Kupatula ngati kuloledwa, kutalika kwa chitoliro chilichonse kudzayesedwa ndi hydro-static popanda kutayikira kudzera pakhoma la chitoliro.
Kuyesa kwamagetsi kosawononga-monga m'malo mwa kuyesa kwa hydro-static, thupi lonse la chitoliro chilichonse lidzayesedwa ndi mayeso osawononga magetsi.kumene kuyesedwa kosawonongeka kwa magetsi kumachitidwa, kutalika kwake kudzalembedwa ndi zilembo "NDE"
Kuyeza kwa ultrasonic
Kufufuza kwamakono kwa eddy
Chitoliro chopanda kanthu, zokutira zakuda (zosinthidwa);
Zonsezi zimathera ndi otetezera mapeto;
Mapeto omveka, mapeto a bevel;
Kuyika chizindikiro.
Kunja Diameter | Kutalika kwa kunja kwa milu ya chitoliro sikuyenera kusiyana kuposa ± 1% kuchokera m'mimba mwake yomwe yatchulidwa. | ||
Khoma makulidwe | Makulidwe a khoma nthawi iliyonse siyenera kupitirira 12.5% pansi pa makulidwe odziwika a khoma. | ||
Utali | Milu ya mapaipi iyenera kuperekedwa motalika mwachisawawa, kutalika kwachisawawa kawiri, kapena muutali wofanana monga momwe zafotokozedwera mu dongosolo logulira, molingana ndi malire awa: | Kutalika kwachisawawa kamodzi | 16 mpaka 25ft (4.88 mpaka 7.62mm), inchi |
Utali wowirikiza kawiri | Kupitilira 25ft (7.62m) yokhala ndi pafupifupi 35ft (10.67m) | ||
Utali wofanana | kutalika monga momwe zafotokozedwera ndi kusintha kovomerezeka kwa ±1 mkati. | ||
Kulemera | Utali uliwonse wa mulu wa chitoliro uyenera kuyezedwa padera ndipo kulemera kwake sikuyenera kusiyana kuposa 15% kuposa kapena 5% pansi pa kulemera kwake, kuwerengeredwa pogwiritsa ntchito kutalika kwake ndi kulemera kwake pa kutalika kwake. |
