Kunetseka kunosara kweLsaw pombi kunonyanya kukonzerwa nekutonhora kusingaonekwe. Kusara kushungurudzika ndiko kuzviratidza kwemukati chikamu kuenzana kushushikana pasina simba rekunze. Uku kushungurudzika kunosara kuripo muzvikamu zvinopisa zvezvikamu zvakasiyana zvezvikamu zvakasiyana. Iyo yakakura chikamu chikamu chikamu cheGeneral Chikamu chesimbi, chikuru kushushikana kunosara.
Kunyangwe kushushikana kusara kuri kuzvifunga, kuchine chekuita nekuita kwekuita kwesimbi yenhengo pasi peimba yekunze. Semuenzaniso, zvinogona kuve nemhedzisiro yakaipa pane deformation, kugadzikana uye kupera simba kuramba. Mushure mekushandiswa kweTold, iyo isiri-simbi yekubatanidza muLsaw pombi inodzvanywa mumashiti akaonda, zvichikonzera kuomesa. Ipapo mhedziso yakanyanya kunatsa kwazvo kuita kweLsaw pombi padhuze nengarasi Dambudziko remunharaunda rinokurudzirwa neWeld shrinkage kazhinji kazhinji kakawanda kakawanda shunzi yekupa, iyo yakakura kwazvo kupfuura iyo yakakonzerwa nemutoro. Mukuwedzera, LSAW PEPE ichave nemitsara ine yakawanda t-welds, saka mukana wekutora urema hwakanyanya kuvandudzwa zvikuru. Zvakare, iyo inosara ichishungurudza kushushikana kuT-Weld yakakura, uye simbi yeWeld inowanzove iri mumamiriro ezvinhu matatu-matatu ekunetseka, ayo anowedzera mukana wekupwanya.
Iyo Welding SEAM yeSpiral yakakundwa ARC yeARC Pipi inogoverwa mumutsara weSpiraled, uye maWels akareba. Kunyanya kana Welding mumamiriro ezvinhu ane simba, iyo weld inosiya nzvimbo yekugadzira isati yatonhorera, iyo iri nyore kuburitsa maunzi inopisa. Nhungamiro yekupaza iri kufanana neWeld uye inoumba angle inosanganisira neganda renji pombi axis, kazhinji kutaura, kona iri pakati pe30-70 °. Kona iyi ingori ichingoenderana neyekutsamwa nehasha kukona, saka kukotama, kakawanda, zvinomanikidzwa uye anti-twist zvivakwa zvisina kunaka seyini yeLSAW. Panguva imwecheteyo, nekuda kwekugumira kweWelding chinzvimbo, chigadziko nehove dzinotambudza seam dzinokanganisa kutaridzika. Naizvozvo, iyo NT yeSsaw Pipe welds inofanirwa kusimbiswa kuve nechokwadi chekutakura mhando, neimwe nzira Ssaw pombi haifanire kushandiswa mune zvakakosha simbi zvigadzirwa.
