Kuyerekeza kwa njira zopangira chitoliro cha lsaw ndi chitoliro cha dsaw

Longitudinal Submerge-arc Welded mipope posachedwapa LSAW chitoliro ndi mtundu wa zitsulo chitoliro amene kuwotcherera msoko ndi kotalika kufanana ndi chitoliro zitsulo, ndi zopangira ndi mbale zitsulo, kotero makulidwe khoma la mipope LSAW akhoza kulemera kwambiri mwachitsanzo 50mm. , pamene m'mimba mwake amangokhala 1420mm kwambiri.LSAW chitoliro ali ndi ubwino wa ndondomeko yosavuta kupanga, mkulu kupanga dzuwa, mtengo wotsika.

Chitoliro cha Double Submerged Arc Welded (DSAW) ndi mtundu wa chitoliro chachitsulo chowotcherera chozungulira chomwe chimapangidwa ndi koyilo yachitsulo ngati zopangira, nthawi zambiri zimakhala zotentha komanso zowotcherera ndi mbali ziwiri zowotcherera arc.Kotero kutalika kwa chitoliro chimodzi cha DSAW kungakhale 40meters pamene kutalika kwa chitoliro cha LSAW ndi mamita 12 okha.Koma makulidwe apamwamba a khoma la mapaipi a DSAW amatha kukhala 25.4mm kokha chifukwa cha kuchepa kwa ma koyilo otentha.

Chodziwika bwino cha chitoliro cha chitsulo chozungulira ndikuti m'mimba mwake imatha kukhala yayikulu kwambiri, Cangzhou Spiral Steel Pipes Group Co.ltd imatha kupanga mapaipi akulu akulu okhala ndi m'mimba mwake 3500mm kwambiri.Panthawi yopangira, koyilo yachitsulo imapunduka mofanana, kupanikizika kotsalira kumakhala kochepa, ndipo pamwamba pake sichimawombera.The kukonzedwa ozungulira zitsulo chitoliro ali kusinthasintha kwambiri kukula osiyanasiyana awiri ndi khoma makulidwe, makamaka kupanga mkulu-kalasi, chitoliro chachikulu khoma makulidwe, ndi awiri ang'onoang'ono ndi chitoliro chachikulu khoma makulidwe, amene ali ndi ubwino wosayerekezeka pa njira zina.Ikhoza kukwaniritsa zofunikira zambiri za ogwiritsa ntchito muzitsulo zazitsulo zozungulira.Njira yowotcherera ya arc yokhala ndi mbali ziwiri imatha kuzindikira kuwotcherera pamalo abwino kwambiri, zomwe sizili zophweka kukhala ndi zolakwika monga kusalongosoka, kupatuka kwa kuwotcherera ndi kulowa kosakwanira, ndipo ndikosavuta kuwongolera mtundu wa kuwotcherera.Komabe, poyerekeza ndi chitoliro chowongoka chowongoka chokhala ndi kutalika komweko, kutalika kwa weld kumawonjezeka ndi 30 ~ 100%, ndipo liwiro lopanga ndilotsika.
