Spiral steel pipe tkulamulira kwa mlengalenga

Spiral zitsulo chitoliro kuwotcherera kutentha makamaka amakhudzidwa ndi mkulu-pafupipafupi eddy matenthedwe mphamvu, mkulu-pafupipafupi Eddy panopa Kutentha mphamvu makamaka amakhudzidwa pafupipafupi, mphamvu ndi matenthedwe Eddy panopa mafunde pafupipafupi ndi molingana ndi lalikulu;komanso ndi mafunde amakono mafupipafupi kukokera voteji, panopa ndi capacitance, inductance.

Pamene kusowa kwa kutentha kumalowa, m'mphepete mwa weld umatenthedwa mpaka kutentha kochepa kuposa kuwotcherera, kapangidwe kazitsulo kumakhalabe kolimba, kupanga kusakanikirana kosakwanira kapena kulowa;osakwanira pamene athandizira kutentha, kuwotcherera m'mphepete pa mkangano soldering kutentha, chifukwa mu kuwotchedwa kapena droplet, kuti weld mapangidwe Mapanga.

Kuwotcherera multilayer wa spiral welded zitsulo chitoliro amaganiziranso yapakati-wosanjikiza kutentha kulamulira mlingo kuzirala pafupi ndi weld zone.Kutentha kwa mawonekedwe ndi kutentha kwa preheat nthawi zambiri kumakhala kofanana.Popewa kutenthedwa malo pafupi ndi msoko zone pakati pamwamba wosanjikiza kuteteza ozizira mng'alu kutentha pa Mipikisano pass kuwotcherera.Pambuyo mankhwala kutentha ndi kuwotcherera kutentha payipi yomanga si kawirikawiri anachita pambuyo kutentha mankhwala pambuyo kuwotcherera ndi kutentha mankhwala.Koma pomanga m'dera la alpine, pamene kutentha kwapakati-preheat ndi mawonekedwe a kutentha kumakhala kovuta kwambiri, ndikofunikira kutenga ziwalo zina pambuyo pa kuwotcherera kutentha ndi kutentha.

Spiral zitsulo kukhazikitsa ndondomeko

Ozungulira chitoliro ntchito kwa malo, choyamba malinga ndi zida ndi zovekera udindo utsi chitoliro, ndi m'munda adzakhala enieni kutalika kwa aliyense chitoliro cha muyeso ndi zabwino, chizindikiro kukula enieni ndi makonzedwe udindo kuti atsogolere mawonekedwe kutsutsidwa, pansi kugwiritsa ntchito chubu cha crane, chubu chotsika pokweza gulaye ya nayiloni kuti muteteze kutsekereza chitoliro.

1: kukonza pakamwa

Kukonza madoko anaikira mu fakitale payipi processing watha, pofuna kuonetsetsa khalidwe kuwotcherera, pamaso kuwotcherera anachitidwa anayendera mabuku, kudzudzulidwa, kupanga chitoliro mapeto, bevel ngodya, blunt m'mphepete, roundness, etc., ndi mogwirizana ndi anzawo. mu zofunika olowa kukula, kufunika munthu chitoliro anachita m'munda beveling ndondomeko, ntchito mpweya kuwotcherera kudula, kuchotsa slag ndiyeno ntchito gudumu opukutidwa yosalala.

Njira zogwirira ntchito: Yang'anani kukula kwa cholumikizira cha mawonekedwe→matayala omveka bwino→kudziwa ndi kusintha malo a zitsulo chitoliro longitudinal welds anadzandima→njira yoyamba yoyang'ana zowongoka imasintha kukula kwa gap→zingwe zamapaipi zikuyenda molunjika→kuwotcherera malo

2: kuwotcherera

Kuwotcherera kwa mawonekedwe pogwiritsa ntchito kuwotcherera kwa arc, kuchirikizanso, kupulumuka kawiri, ndipo nthawi iliyonse msoko wowotcherera ukamalizidwa, nsonga iliyonse yowotcherera imatsogolera kugwedezeka.Kukonza kuwotcherera chitoliro olowa ayenera patsogolo pakamwa, slag, bevel ngodya chitoliro kumapeto kwa nkhope, osamveka m'mphepete, kusiyana ayenera kukhala zogwirizana ndi specifications;kopanira sizingathandize Mvula kuwotcherera kapena Kutentha anzawo kusiyana narrowing kusiyana kuwotcherera.Zofananira ziyenera kukhala zonyezimira ndi khoma lamkati, lokhala ndi wolamulira wautali wa 300mm mozungulira khoma lamkati lozungulira mawonekedwe, doko lolakwika limalola cheke cheke kuyenera kukhala nthawi 0.2 kusiyana pakati pa makulidwe a khoma, ndipo osaposa 2mm.
