Kufunika kwachitoliro chachitsulo cha kaboni chozungulira chozunguliraSitinganyalanyazidwe posankha chitoliro choyenera kugwiritsidwa ntchito m'mafakitale osiyanasiyana. Mapaipi awa amadziwika kuti ndi amphamvu komanso okhazikika, amagwiritsidwa ntchito kwambiri poyendetsa mafuta ndi gasi, malo oyeretsera madzi, ntchito zomanga, ndi zina zambiri. Tidzafufuza kwambiri zaukadaulo wa chitoliro chachitsulo cha kaboni cholumikizidwa ndi spiral welded, makamaka pa njira yake yowotcherera ndi kufotokozera kwake.

Kuwotcherera Kozungulira: Chidule

Mapaipi achitsulo cha kaboni opangidwa ndi spiral welded amapangidwa kudzera mu njira yolumikizira yozungulira, yomwe imaphatikizapo kupota ndi kulumikiza zitsulo zopitilira kukhala mawonekedwe a cylindrical. Njirayi ndi yabwino chifukwa imatsimikizira makulidwe ofanana mu chitoliro chonsecho. Njira yolumikizira yozungulira imapereka zabwino zambiri, kuphatikiza mphamvu yowonjezera, kukana kwambiri kupsinjika, komanso kuthekera konyamula katundu bwino. Kuphatikiza apo, imatha kupanga mapaipi amitundu yosiyanasiyana, kuwapangitsa kukhala oyenera kugwiritsidwa ntchito mosiyanasiyana.

Ukadaulo wowotcherera chubu cha kaboni:

Kuwotcherera mapaipi a kabonindi gawo lofunika kwambiri pakupanga chifukwa limatsimikizira kulumikizana kolimba komanso kodalirika pakati pa machubu.

- Kuwotcherera kwa arc yoviikidwa m'madzi (SAW): Ukadaulo uwu umagwiritsa ntchito ma electrode oyendetsedwa ndi mphamvu mosalekeza omwe amamizidwa mu granular flux. Uli ndi liwiro lalikulu lowotcherera komanso kulowa bwino kwambiri, koyenera mapaipi akuluakulu.

- Kuwotcherera kwa Gas Metal Arc (GMAW/MIG): GMAW imagwiritsa ntchito waya wowotcherera ndi mpweya woteteza kuti ipange kutentha kwa kuwotcherera. Imaonedwa kuti ndi yogwiritsidwa ntchito kwambiri komanso yoyenera mapaipi okhala ndi makulidwe osiyanasiyana.

- Kuwotcherera kwa arc ya tungsten ya gasi (GTAW/TIG): GTAW imagwiritsa ntchito ma electrode a tungsten osagwiritsidwa ntchito komanso mpweya woteteza. Imapereka kuwongolera kolondola kwa njira yowotcherera ndipo nthawi zambiri imagwiritsidwa ntchito powotcherera kwapamwamba kwambiri pamapaipi opyapyala.

Kuti zitsimikizire kuti mapaipi achitsulo cha kaboni olumikizidwa mozungulira akugwirizana ndi ntchito zosiyanasiyana, amapangidwa motsatira miyezo ndi zofunikira zamakampani ena. Mafotokozedwe apadera ndi awa:

1. API 5L: Mafotokozedwe a American Petroleum Institute (API) amatsimikizira ubwino ndi kulimba kwa mapaipi omwe amagwiritsidwa ntchito kunyamula gasi, mafuta, ndi madzi mumakampani amafuta ndi gasi.

2. ASTM A53: Chida ichi chimaphatikizapo chitoliro chachitsulo chakuda ndi chotentha chomwe chimayikidwa mu galvanized chomwe chimayikidwa mu galvanized steel chomwe chingagwiritsidwe ntchito zosiyanasiyana kuphatikizapo madzi, gasi, ndi mayendedwe a nthunzi.

3. ASTM A252: Mfundo imeneyi imagwira ntchito pa chitoliro chachitsulo cholumikizidwa komanso chopanda msoko kuti chipereke chithandizo chofunikira pa ntchito zauinjiniya monga maziko omanga ndi kumanga milatho.

4. EN10217-1/EN10217-2: Miyezo ya ku Ulaya imaphimba mapaipi achitsulo olumikizidwa a mapaipi opanikizika ndi osagwiritsa ntchito zitsulo zoyendera mapaipi motsatana.

Pomaliza:

Chitoliro chachitsulo cha kaboni cholumikizidwa ndi spiral chakhala chinthu chofunikira kwambiri m'mafakitale ambiri chifukwa cha mphamvu zake zapamwamba komanso kulimba kwake. Kumvetsetsa ukadaulo ndi njira zolumikizira zomwe zimagwiritsidwa ntchito ndikofunikira kwambiri posankha chitoliro choyenera pa ntchito inayake. Mukatsatira miyezo yodziwika bwino yamakampani, mutha kukhala otsimikiza za mtundu, kudalirika, komanso moyo wautali wa mapaipi awa. Kaya ndi mayendedwe amafuta ndi gasi, malo oyeretsera madzi kapena mapulojekiti omanga, chitoliro chachitsulo cha kaboni cholumikizidwa ndi spiral chimapereka yankho lodalirika pazosowa zanu zonse za mapaipi.
