1. Kuyerekeza kwa njira yopangira
Njira yopangachitoliro chachitsulo chowongokandi yosavuta. Njira zazikulu zopangira ndizomwe zimapangidwira molunjika msokochitoliro chachitsulondiMizinda arc welded mowongoka msoko zitsulo chitoliro. Woongoka msoko zitsulo chitoliro ali mkulu kupanga dzuwa, mtengo wotsika ndi chitukuko mofulumira.
Mphamvu yachitoliro chachitsulo chozunguliranthawi zambiri imakhala yapamwamba kuposa chitoliro chachitsulo chowongoka. Njira yayikulu yopanga ndikuwotcherera arc pansi pamadzi. Machubu achitsulo ozungulira amatha kupanga machubu otsekemera okhala ndi ma diameter osiyanasiyana amtundu womwewo, kapenawelded machubuzokhala ndi mainchesi akuluakulu kuchokera ku ma billets opapatiza.
Komabe, poyerekeza ndi mipope yowongoka yachitsulo yautali womwewo, kutalika kwa kuwotcherera kwawonjezeka ndi 30% ndi 100% motsatana, ndipo liwiro la kupanga ndilotsika. Chifukwa chake, mapaipi akulu achitsulo m'mimba mwake nthawi zambiri amawotcherera ndi kuwotcherera kozungulira, ndipo mapaipi achitsulo ang'onoang'ono am'mimba mwake nthawi zambiri amawotcherera ndi kuwotcherera kwa msoko wowongoka.
Popangazazikulu m'mimba mwake molunjika msoko mipope zitsulomu makampani, T woboola pakati kuwotcherera luso ntchito, ndiko kuti, ochepa mipope zitsulo owongoka msoko ndi matako olowa ndi olumikizidwa kukakwaniritsa utali wofunika wa polojekiti. Zowonongeka za chitoliro chachitsulo chooneka ngati T chowongoka chidzawonjezeka kwambiri, ndipo kuwotcherera kotsalira kwa weld wooneka ngati T ndi kwakukulu. Chitsulo chowotcherera nthawi zambiri chimakhala pansi pa zovuta za triaxial, zomwe zimawonjezera mwayi wosweka.
Kuphatikiza apo, malinga ndi malamulo aukadaulo a kuwotcherera arc pansi pamadzi, weld iliyonse iyenera kuthandizidwa ndi arc ndi kuzimitsa moto. Komabe, chitoliro chilichonse chachitsulo sichingakwaniritse izi panthawi yowotcherera mozungulira, kotero kuti zolakwika zambiri zowotcherera zitha kuchitika pakuzimitsa kwa arc.
2. Kuyerekeza kwa magawo a magwiridwe antchito
Chitolirocho chikakumana ndi kupsinjika kwamkati, zovuta ziwiri zazikulu nthawi zambiri zimapangidwira pakhoma la chitoliro, zomwe ndi kupsinjika kwa radial ndi axial stress. Kupsyinjika kwakukulu pa weld, kumene α Ndikokopera kozungulira kwachitoliro chachitsulo chozungulira.
Kupanikizika kwakukulu pa spiral weld ndiko kupsinjika kwakukulu kwa chitoliro chachitsulo chowongoka. Pansi pa kukakamiza komweko, makulidwe a khoma la mapaipi achitsulo ozungulira okhala ndi m'mimba mwake womwewo ndi wocheperako kuposa mapaipi achitsulo owongoka.
