Ubwino ndi kuipa kozungulira welded zitsulo chitoliro

Ubwino wa spiral welded pipe:
(1) Ma diameter osiyanasiyana a mipope yachitsulo yozungulira amatha kupangidwa ndi koyilo yofanana m'lifupi, makamaka mipope yachitsulo yokhala ndi mainchesi akulu imatha kupangidwa ndi koyilo yopapatiza yachitsulo.
(2) Pansi pa kupanikizika komweko, kupsinjika kwa msoko wowotcherera wozungulira kumakhala kocheperako kuposa msoko wowotcherera wowongoka, womwe ndi 75% ~ 90% wa chitoliro chowotcherera chowotcherera chowotcherera chowotcherera, kotero chimatha kupirira kuthamanga kwakukulu.Poyerekeza ndi chitoliro chowongoka chowongoka chokhala ndi m'mimba mwake womwewo wakunja, makulidwe a khoma la chitoliro chowotcherera chozungulira amatha kuchepetsedwa ndi 10% ~ 25% pansi pamavuto omwewo.
(3) Mulingo wake ndi wolondola.Nthawi zambiri, kulolerana kwapakati sikupitilira 0.12% ndi ovality ndi zosakwana 1%.Kukula ndi kuwongola kungasiyidwe.
(4) Ikhoza kupangidwa mosalekeza.Kunena zongopeka, imatha kupanga chitoliro chachitsulo chosatha chokhala ndi mutu wawung'ono ndi kudula mchira, ndipo imatha kusintha kuchuluka kwachitsulo ndi 6% ~ 8%.
(5) Poyerekeza ndi chitoliro chowongoka chamsoko, chimakhala ndi ntchito yosinthika komanso kusintha kwamitundu yosiyanasiyana ndikusintha.
(6) Kulemera kwa zida zopepuka komanso ndalama zochepa zoyambira.Ikhoza kupangidwa kukhala kalavani yamtundu wamtundu wa mafoni kuti apange mipope yowotcherera mwachindunji pamalo omanga pomwe mapaipi amayikidwa.

The kuipa ozungulira welded chitoliro ndi: chifukwa ntchito adagulung'undisa Mzere zitsulo monga zopangira, pali ena kachigawo pamapindikira, ndi kuwotcherera mfundo ndi zotanuka Mzere zitsulo m'mphepete m'dera, choncho n'zovuta agwirizane ndi kuwotcherera mfuti ndi kuwotcherera mfundo. bwanji kuwotcherera khalidwe.Chifukwa chake, zida zowunikira zowotcherera zovuta komanso zowunikira zabwino ziyenera kukhazikitsidwa.
