Spiral Welded Carbon Steel Pipe For Water Line Tubing
Tsegulani:
Kufunika kwaspiral welded carbon steel pipesizinganyalanyazidwe posankha chitoliro choyenera cha ntchito zosiyanasiyana za mafakitale.Odziwika chifukwa cha mphamvu zawo zapamwamba komanso zolimba, mapaipiwa amagwiritsidwa ntchito kwambiri poyendetsa mafuta ndi gasi, malo opangira madzi, ntchito zomanga, ndi zina.Tidzayang'ana mbali zaukadaulo za spiral welded carbon steel chitoliro, molunjika kwambiri panjira yake yowotcherera komanso mawonekedwe ake.
Kuwotcherera kozungulira: mwachidule
Spiral welded carbon steel mapaipi amapangidwa kudzera mu njira yowotcherera yozungulira, yomwe imaphatikizapo kuwotcherera ndi kuwotcherera zitsulo zosalekeza kukhala mawonekedwe a cylindrical.Njirayi imakondedwa chifukwa imatsimikizira makulidwe a yunifolomu mu chitoliro chonse.Njira yowotcherera yozungulira imakhala ndi zabwino zambiri, kuphatikiza mphamvu zowonjezera, kukana kupsinjika, komanso kunyamula katundu moyenera.Kuphatikiza apo, imatha kupanga mipope yamitundu yosiyanasiyana, kuwapanga kukhala oyenera kugwiritsa ntchito mitundu yosiyanasiyana.
Ukadaulo wowotcherera machubu a Carbon:
Kuwotchera chitoliro cha kabonindi gawo lofunika kwambiri pakupanga zinthu chifukwa zimatsimikizira kugwirizana kolimba komanso kodalirika pakati pa machubu.
- Submerged arc welding (SAW): Ukadaulo uwu umagwiritsa ntchito electrode yoyendetsedwa mosalekeza yomizidwa mu granular flux.Iwo ali mkulu kuwotcherera liwiro ndi malowedwe kwambiri, oyenera mipope lalikulu awiri.
- Gas Metal Arc Welding (GMAW/MIG): GMAW imagwiritsa ntchito waya wowotcherera ndi mpweya wotchinga kuti ipange kutentha.Amaonedwa kuti ndi osinthasintha komanso oyenera mapaipi a makulidwe osiyanasiyana.
- Kuwotcherera kwa tungsten arc gasi (GTAW/TIG): GTAW imagwiritsa ntchito ma elekitirodi a tungsten osagwiritsidwa ntchito ndi magesi otchinga.Amapereka kuwongolera bwino kwa njira yowotcherera ndipo nthawi zambiri amagwiritsidwa ntchito popangira ma welds apamwamba pamapaipi owonda kwambiri.

Kuonetsetsa kuti kugwirizana kwa ozungulira welded mpweya zitsulo mapaipi mu ntchito zosiyanasiyana, iwo amapangidwa ndi mfundo makampani enieni ndi specifications.Zodziwika bwino zimaphatikizapo:
1. API 5L: Mafotokozedwe a American Petroleum Institute (API) amaonetsetsa kuti mapaipi omwe amagwiritsidwa ntchito kunyamula gasi, mafuta, ndi madzi ndi abwino komanso osalimba.
2. ASTM A53: Izi zimakwirira chitoliro chachitsulo chakuda ndi chotenthetsera chakuda ndi chotentha chogwiritsa ntchito zosiyanasiyana kuphatikiza madzi, gasi, ndi kayendedwe ka nthunzi.
3. ASTM A252: Izi zikugwira ntchito papaipi yachitsulo yowotcherera komanso yopanda msoko kuti muwunjike kuti apereke chithandizo chofunikira pama projekiti a zomangamanga monga maziko omanga ndi kumanga mlatho.
TS EN 10217-1 / EN10217-2 Miyezo yaku Europe imaphimba mapaipi achitsulo otenthedwa ndi mapaipi achitsulo omwe si aloyi pamakina oyendera mapaipi motsatana.
Pomaliza:
Spiral welded carbon steel chitoliro chakhala chofunikira kwambiri pamafakitale osawerengeka chifukwa cha mphamvu zake zapamwamba komanso kulimba kwake.Kumvetsetsa zaukadaulo ndi njira zowotcherera zomwe zimakhudzidwa ndikofunikira pakusankha chitoliro choyenera cha polojekiti inayake.Potsatira miyezo yodziwika yamakampani, mutha kutsimikiziridwa za mtundu, kudalirika komanso moyo wautali wa mapaipi awa.Kaya ndi mayendedwe amafuta ndi gasi, malo opangira madzi kapena ntchito zomanga, chitoliro cha spiral welded carbon steel chimapereka yankho lodalirika pazosowa zanu zonse zamapaipi.
