Kapangidwe ka Chitoliro cha Longitudinal Submerged-arc Welded:

Longitudinal Submerged-arc Welded(LSAW) Chitoliro chimagwiritsa ntchito ukadaulo wowotcherera wa arc pansi pamadzi, pogwiritsa ntchito kuwotcherera kwa filler, tinthu tating'onoting'ono totetezera kukwiriridwa 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

Kulongedza zaLongitudinal Submerged-arc Welded Pipe

Chitoliro chopanda kanthu, zokutira zakuda (zosinthidwa);
Zonsezi zimathera ndi otetezera mapeto;
Mapeto omveka, mapeto a bevel;
Kuyika chizindikiro.

Kulekerera kwa awiri akunja, makulidwe a khoma, kutalika ndi kulemera kwake:

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.
