Kusiyana Pakati mwauzimu welded chitoliro ndi Lolunjika welded chitoliro

Kusiyanitsa kwakukulu pakati pa mapaipi awiri otenthedwa a chitoliro chazitsulo chowongolera ndi chitoliro chowongoka molondola ndi kusiyana kwa mawonekedwe owotcherera.

Mwauzimu welded chitoliro ndi otsika mpweya mpweya structural zitsulo kapena otsika aloyi kandalama zitsulo Mzere adagulung'undisa mu chubu akusowekapo ndi ena helix ngodya (amatchedwanso kupanga ngodya), kenako welded ndi kupanga olowa chitoliro, amene angagwiritse ntchito Mzere yopapatiza chitsulo Kupanga mapaipi akulu akulu azitsulo. Chitoliro chauzimu chotsekera makamaka chimazungulira ma arc welded chitoliro (SSAW), chomwe chimakonda kugwiritsidwa ntchito popanga mapaipi angapo amagetsi ku China. Mafotokozedwe ake amafotokozedwa ndi "makulidwe akunja * makulidwe amakoma". Mapaipi owotchera mwauzimu ndi otsekemera amodzi komanso otetezedwa. Chitoliro welded adzaonetsetsa kuti mayeso hayidiroliki ndi mphamvu kwamakokedwe ndi ntchito kuzizira kupinda weld ndi zogwirizana ndi malamulo.

Chitoliro chowongoka chopindika ndichowonekera pafupipafupi komanso gawo loyandikira lomwe liyenera kupangidwa ndi solder wosanjikiza isanapangidwe ndi makina owumba, ndipo m'mphepete mwa chubu mulibe mkangano ndi kusungunuka, ndikusakanikirana pansi pa kukanikiza kwina, kuzirala kozizira. Chitoliro chowongolera pafupipafupi chowongolera chimagwiritsidwa ntchito momwe m'mphepete mwa chitoliro mulibe chosungunuka ndi ma frequency aposachedwa (ERW), omwe amatchedwa seam yolunjika yolowetsa arc welded pipe (LSAW) posungunuka ndi arc yamagetsi.

Mphamvu ya chitoliro chazitsulo nthawi zambiri chimakhala chachikulu kuposa chitoliro chowongoka. Njira yayikulu yopangira ndikutsekemera kwa arc. Mwauzimu welded chitoliro zingabweretse mipope welded ndi awiri osiyana chitoliro ndi m'lifupi yemweyo opanda, ndipo akhoza kupanga mipope welded ndi diameters zikuluzikulu ndi akusowekapo yopapatiza.

Kupanga kwa chitoliro chowongoka bwino ndikosavuta, makamaka pakupanga, komwe kumagawika chitoliro chowongolera pafupipafupi komanso kumiza arc kutulutsa chitoliro chowongoka. Chitoliro chowongoka cholumikizidwa chimakhala ndi magwiridwe antchito ambiri, mtengo wotsika komanso chitukuko mwachangu.

Komabe, poyerekeza ndi chitoliro chowongoka cholumikizira chitoliro cha kutalika komweko, kutalika kwa weld kumawonjezeka ndi 30 mpaka 100, ndipo kuthamanga kwakapangidwe kotsika. Chifukwa chake, mapaipi ocheperako m'mimba amakhala owongoka mosalala, pomwe mipope yayikulu yayikulu imakhala yolimba.
