Chitoliro Chowotchedwa VS Chitoliro Chopanda Chitsulo

Njira zonse za Electric resistance welded (RW) ndi zopanda (SMLS) zopangira zitoliro zazitsulo zakhala zikugwiritsidwa ntchito kwa zaka zambiri; m'kupita kwa nthawi, njira zopangira iliyonse zapita patsogolo. Ndiye chabwino nchiyani?
1. Kupanga welded chitoliro
Chitoliro chowotcherera chimayamba ngati riboni lalitali lopiringizika lachitsulo lotchedwa skelp. Chigobacho chimadulidwa mpaka kutalika komwe kumafunikira, zomwe zimapangitsa kuti pakhale pepala lathyathyathya lamakona anayi. M'lifupi mwake mbali zazifupi za chitolirocho zidzakhala zozungulira kunja kwa chitoliro, mtengo womwe ungagwiritsidwe ntchito kuwerengetsa kukula kwake kwakunja.
Mapepala amakona anayi amadyetsedwa kudzera pamakina ogudubuza omwe amapiringiza mbali zazitali kupita kwina, kupanga silinda. Mu njira ya ERW, mphamvu yamagetsi yothamanga kwambiri imadutsa pakati pa m'mphepete mwake, zomwe zimapangitsa kuti zisungunuke ndikuphatikizana pamodzi.
Ubwino wa chitoliro cha ERW ndikuti palibe zitsulo zophatikizika zomwe zimagwiritsidwa ntchito ndipo msoko wa weld suwoneka kapena kumva. Izi ndi zotsutsana ndi kuwotcherera kwa arc (DSAW), komwe kumasiya mkanda wodziwika bwino womwe uyenera kuchotsedwa kutengera ntchito.
Njira zopangira ma welded mapaipi zakhala zikuyenda bwino m'zaka zapitazi. Mwina kupititsa patsogolo kofunika kwambiri kwakhala kusintha kwa mafunde amagetsi othamanga kwambiri powotcherera. Zaka za m'ma 1970 zisanafike, magetsi otsika ankagwiritsidwa ntchito. Ma weld seams opangidwa kuchokera ku ERW otsika pafupipafupi anali okonda dzimbiri komanso kulephera kwa msoko.
Ambiri welded chitoliro mitundu amafuna kutentha mankhwala pambuyo kupanga.

2. Kupanga chitoliro chopanda msoko
Mipope yopanda msoko imayamba ngati chitsulo cholimba cha cylindrical chotchedwa billet. Zikadatentha, ma billet amabooledwa pakati ndi mandrel. Chotsatira ndikugudubuza ndi kutambasula billet yopanda kanthu. Billet imakulungidwa ndendende ndikutambasulidwa mpaka itakumana ndi kutalika, m'mimba mwake ndi makulidwe a khoma monga momwe zafotokozedwera ndi dongosolo la kasitomala.
Mitundu ina ya mapaipi opanda msoko amawuma akamapangidwa, chifukwa chake kutentha pambuyo popanga sikofunikira. Ena amafunikira chithandizo cha kutentha. Onaninso za mtundu wa chitoliro chopanda msoko chomwe mukuganizira kuti mudziwe ngati chidzafunika chithandizo cha kutentha.

3. Malingaliro a mbiri yakale ndi milandu yogwiritsira ntchito welded vs. seamless steel pipe
ERW ndi mapaipi achitsulo osasunthika alipo ngati njira zina masiku ano makamaka chifukwa cha mbiri yakale.
Nthawi zambiri, chitoliro chowotcherera chimawonedwa ngati chofooka chifukwa chimaphatikizapo msoko wowotcherera. Chitoliro chopanda msoko chinalibe cholakwika chopangidwa ndi ichi ndipo chinkawoneka ngati chotetezeka. Ngakhale zili zowona kuti welded chitoliro zikuphatikizapo msoko zomwe zimapangitsa kuti theoretically ofooka, kupanga njira ndi khalidwe chitsimikizo regimens aliyense bwino mpaka kumlingo kuti welded chitoliro adzachita monga ankafunira pamene kulolerana ake si udapyola. Ngakhale kuti phindu lowoneka bwino likuwonekera bwino, kutsutsa kwa mapaipi osasunthika ndikuti kugudubuza ndi kutambasula kumapanga makulidwe osagwirizana ndi khoma lachitsulo poyerekeza ndi makulidwe enieni a mapepala achitsulo omwe amapangidwira kuwotcherera.
Miyezo yamakampani yomwe imayang'anira kupanga ndi kufotokozedwa kwa ERW ndi chitoliro chachitsulo chosasunthika chikuwonetsabe malingaliro amenewo. Mwachitsanzo, mapaipi opanda msoko amafunikira pakugwiritsa ntchito mphamvu zambiri, kutentha kwambiri m'mafakitale amafuta & gasi, opanga magetsi ndi mafakitale ogulitsa mankhwala. Mapaipi a welded (omwe nthawi zambiri amakhala otsika mtengo kupanga ndipo amapezeka kwambiri) amafotokozedwa m'mafakitale onse malinga ngati kutentha, kupanikizika ndi zina zautumiki sizikupitilira zomwe zalembedwa mulingo womwe ukugwiritsidwa ntchito.
M'mawonekedwe, palibe kusiyana pakati pa ERW ndi chitoliro chachitsulo chosasokonezeka. Ngakhale kuti ziwirizi zitha kufotokozedwa mosinthana, sizingakhale zomveka kutchula mopanda msoko pomwe chitoliro chotchipa chotchipa chimagwira ntchito mofananamo.

4. Tiwonetseni zolemba zanu, pemphani mtengo ndikupeza chitoliro chanu mofulumira
Gulu la Zitsulo la Jindalai limakhalabe ndi zida zabwino kwambiri zamapaipi azitsulo zonyezimira komanso zopanda msoko pamsika. Timapeza katundu wathu kuchokera ku mphero kuzungulira China, kuwonetsetsa kuti ogula apeza chitoliro chomwe chikufunikira mwachangu mosasamala kanthu za zoletsa zilizonse zovomerezeka.
Jindalai atha kukuthandizani kudziwa njira yogulitsira mapaipi kuyambira koyambira mpaka kumapeto kuti muwonetsetse kuti mumapeza zomwe mukufuna mwachangu ikafika nthawi yogula. Ngati kugula mapaipi kuli mtsogolo mwanu, funsani mtengo. Tikupatsirani imodzi yomwe imakupezerani zomwe mukufuna mwachangu.
