Spiral welded pipe (SSAW pipe)ndi mtundu wa ozungulira msoko zitsulo chitoliro chopangidwa ndi Mzere zitsulo koyilo ngati zopangira, amene welded ndi basi awiri-waya mbali ziwiri kumizidwa arc ndondomeko kuwotcherera ndi extruded kutentha firiji. Uinjiniya wamadzi, mafakitale a petrochemical, makampani opanga mankhwala, mafakitale amagetsi, ulimi wothirira ndi zomangamanga m'matauni ndi minda yomwe spiralwelded mapaipiamagwiritsidwa ntchito makamaka.

Waukulu ndondomeko makhalidwe ozungulira welded chitoliro:

1. Pakapangidwe kameneka, kupanikizika kotsalira kumakhala kochepa ndipo palibe zokopa pamwamba. The kukonzedwa ozungulira welded chitoliro ali ndi ubwino wosayerekezeka mu kukula ndi specifications osiyanasiyana m'mimba mwake ndi makulidwe khoma, ndipo akhoza kukwaniritsa zofunika kwambiri kwa owerenga zitsulo zozungulira chitoliro specifications.
2. Landirani ukadaulo wowotcherera wa arc wambali ziwiri kuti muthane ndi zolakwika zina, ndipo ndikosavuta kuwongolera mtundu wa kuwotcherera.
3. Chitani kuyendera kwa 100% pazitsulo zachitsulo, kuti mutsimikizire mtundu wa mankhwala.

4. Zipangizo zonse mumzere wonse wopanga zimakhala ndi ntchito yolumikizana ndi makina opangira ma data a pakompyuta kuti azindikire kutumiza kwanthawi yeniyeni, ndipo magawo aukadaulo pakupanga kwawo amayendetsedwa ndi chipinda chowongolera.

Pakuwotchera, zida zotenthetsera kutentha ndi kutentha kwapakati ziyenera kusankhidwa. Zomwe zimachitika kapena zosavuta kuchitika apa ndikuti pamwamba pa gawolo lidzakhudzidwa ndi oxidizing Kutentha sing'anga, ndipo kutentha kwa kutentha kumaposa zofunikira za ndondomeko. Ngati njere za austenite ndi zokhuthala kwambiri, ngakhale malire a tirigu adzasungunuka, zomwe zidzakhudza kwambiri maonekedwe ndi khalidwe lamkati la ziwalozo. Choncho, muzochitika zenizeni, njira zotheka ziyenera kuchitidwa kuti mufufuze zolakwika zoterezi.

Zigawo zosalongosoka zomwe zimapangidwa panthawi yotentha zimazimitsidwa kuti zipeze mawonekedwe a martensite ozimitsidwa ndi kuuma kwakukulu kapena mawonekedwe otsika a bainite omwe ali ndi kuuma pang'ono pang'ono, koma mawonekedwewo ndi osakhazikika komanso osasunthika. Ikagwiritsidwa ntchito popanga, imatenthedwa kuti ipeze mawonekedwe ofunikira ndi katundu. Choncho, tempering ndondomeko magawo adzakhala ndi zimakhudza kwambiri kutentha mankhwala khalidwe la mbali, monga kuuma, tempering brittleness, tempering ming'alu ndi zina zolakwika, ndi miyeso ayenera kumwedwa kupewa zolakwika izi pa tempering.

Njira yoyenera yochizira kutentha ndiyo maziko ndi maziko owonetsetsa kuti magawowo ali oyenerera kutentha kutentha. Mavuto omwe ali pamwambawa atapezeka, amatha kuthetsedwa kuchokera kuzinthu za anthu, makina, zipangizo, njira, maulalo, kuyendera, ndi zina zotero. Kupyolera mu kufufuza ndi chiweruzo, chifukwa cha chilema chingapezeke.

Maluso osungira a spiral welded pipe:

1. Malo osungiramo zinthu kapena malo osungiramo zinthu zapaipi zachitsulo zozungulira ayenera kukhala pamalo aukhondo komanso otayidwa bwino. Udzu ndi zina zonse ziyenera kutsukidwa. Mipiringidzo yazitsulo iyenera kukhala yoyera komanso kutali ndi mafakitale ndi migodi yomwe imatulutsa mpweya woipa kapena fumbi.
2. Zida zomwe zimawononga zitsulo monga asidi, alkali, mchere, ndi simenti sizidzaikidwa m'nyumba yosungiramo katundu, ndipo zitsulo zamitundu yosiyanasiyana ziyenera kuikidwa padera. Pewani chisokonezo ndi kukhudzana dzimbiri.
3. Chigawo chaching'ono ndi chaching'ono, ndodo ya waya, chitsulo chachitsulo, chitoliro chachitsulo chapakati-m'mimba mwake, waya wachitsulo ndi chingwe cha waya, ndi zina zotero.

4. Chitsulo chaching'ono, mbale yachitsulo yopyapyala, chingwe chachitsulo, pepala lachitsulo cha silicon kapena chitoliro chozungulira chozungulira chozungulira chingasungidwe. Zitsulo zamtengo wapatali, zowonongeka zozizira komanso zozizira komanso zitsulo zimatha kusungidwa.
