Zogulitsa zitsulo zosapanga dzimbiri zimagwiritsidwa ntchito kwambiri m'mafakitale ambiri ndi ntchito chifukwa cha ntchito zawo zabwino komanso katundu.Lero, tikambirana chitoliro chosapanga dzimbiri chosapanga dzimbiri ndi chitoliro cha ERW chosapanga dzimbiri, komanso kusiyana pakati pa zinthu ziwirizi.
Pali kusiyana pakati pa chitoliro chachitsulo chosapanga dzimbiri cha ERW ndi chitoliro chosapanga chitsulo chosapanga dzimbiri.ERW Pipe ndi lalifupi la Electric Resistance Welding.Amagwiritsidwa ntchito kunyamula zamadzimadzi monga mafuta, gasi, ndi zina zotero, mosasamala kanthu za kukakamizidwa, ndipo amagwira ntchito yofunika kwambiri pamapaipi padziko lonse lapansi.Panthawi imodzimodziyo, ndi chitoliro chachitsulo chosasunthika.Mapaipi achitsulo am'bwalo ndi amakona anayi opanda zolumikizira ndi mbiri zopanda pake amagwiritsidwa ntchito ponyamula zakumwa chifukwa cha kupindika kwawo kwakukulu komanso mphamvu ya torsion, komanso kupanga zida zamakina ndi makina.Kawirikawiri, mapaipi a ERW ndi mapaipi opanda zitsulo amagwiritsidwa ntchito pazinthu zosiyanasiyana.
Mapaipi achitsulo osasunthika amapangidwa kuchokera ku mabaluti ozungulira, pomwe mapaipi azitsulo zosapanga dzimbiri a ERW amapangidwa kuchokera kumakoyilo otentha otentha.Ngakhale kuti zipangizo ziwirizi ndizosiyana kwambiri, ziyenera kukumbukiridwa kuti ubwino wa mankhwala omaliza - mapaipi amadalira kwathunthu zinthu ziwirizi - kulamulira khalidwe pakupanga ndi chikhalidwe choyambirira ndi khalidwe la zipangizo.Mapaipi onsewa amapangidwa ndi chitsulo chosapanga dzimbiri chamagulu osiyanasiyana, koma chofala kwambiri ndi chitoliro chopangidwa ndi chitsulo chosapanga dzimbiri 304.
Billet yozungulira imatenthedwa ndikukankhira pa ndodo ya perforated mpaka itengeke.Pambuyo pake, kutalika kwake ndi makulidwe awo amayendetsedwa ndi njira za extrusion.Pankhani ya kupanga mapaipi a ERW, njira yopanga ndi yosiyana kwambiri.Mpukutuwo umapindika kumbali ya axial, ndipo m'mphepete mwake mumawotcherera kutalika kwake konse ndi kuwotcherera kukana.
Machubu achitsulo chosapanga dzimbiri amasonkhanitsidwa pamzere wa msonkhano ndipo amapezeka mu OD mpaka mainchesi 26.Komano, ngakhale makampani apamwamba kwambiri azitsulo omwe ali ndi teknoloji ya ERW amatha kukwaniritsa kukula kwa kunja kwa mainchesi 24.
Popeza mapaipi opanda msoko amatuluka, alibe zolumikizira kumbali ya axial kapena radial.Komano, mapaipi a ERW amapangidwa popinda ma koyilo opindika m'mbali mwake kuti amangiriridwa ndi utali wawo wonse.
Nthawi zambiri, mapaipi opanda msoko amagwiritsidwa ntchito popanga kuthamanga kwambiri, pomwe mapaipi a ERW amagwiritsidwa ntchito kumadera otsika komanso apakati.
Kuphatikiza apo, poganizira zachitetezo chokhazikika cha mapaipi opanda msoko, amagwiritsidwa ntchito kwambiri mumafuta ndi gasi, kuyenga mafuta ndi mafakitale ena amankhwala, ndipo mfundo yoti palibe kutayikira ikufunika kuti zitsimikizire chitetezo cha anthu ndi mabizinesi.Nthawi yomweyo, mapaipi opangidwa bwino a ERW omwe ali pansi paulamuliro wokhazikika atha kugwiritsidwanso ntchito pazinthu zofananira kupatula ntchito wamba monga mayendedwe amadzi, scaffolding ndi mipanda.
Zimadziwika kuti mapeto a mkati mwa mapaipi a ERW nthawi zonse amawongoleredwa ndi njira zabwino zoyendetsera bwino, choncho nthawi zonse amakhala abwino kuposa mapaipi opanda msoko.
Pankhani ya ASTM A53, mtundu wa S umatanthauza kuti mulibe msoko.Type F - ng'anjo, koma kuwotcherera, mtundu E - kukana kuwotcherera.Ndizomwezo.Iyi ndi njira yosavuta yodziwira ngati chitoliro chilibe msoko kapena ERW.
Langizo: ASTM A53 Gulu B ndiyotchuka kwambiri kuposa magiredi ena.Mapaipiwa amatha kukhala opanda zokutira, kapena akhoza kukhala malata kapena kuviika-kuviika malata ndi kupangidwa pogwiritsa ntchito njira yopangira zitsulo kapena zitsulo.M'gawo lamafuta ndi gasi, mapaipi a A53 amagwiritsidwa ntchito pamapangidwe komanso osafunikira.
Ngati mukufuna zambiri zokhudza polojekitiyi, chonde titumizireni kuti mudziwe momwe mulili panopa, mauthenga a gulu la polojekiti, ndi zina zotero.
