Kulimbitsa Umphumphu wa Kapangidwe: Chitoliro cha Chitsulo cha Carbon Chozungulira Cholumikizidwa mu Njira Yowotcherera Chitoliro cha Chitsulo

Dziwitsani

Luso lakuwotcherera chitoliro chachitsulokumafuna kuphatikiza kogwirizana kwa luso, kulondola, ndi zipangizo zabwino kuti zitsimikizire kuti kapangidwe kake ndi koyenera pa ntchito zosiyanasiyana. Pakati pa mitundu yambiri ya mapaipi, mapaipi achitsulo cha kaboni olumikizidwa mozungulira, monga mapaipi a X42 SSAW, ndi otchuka chifukwa cha mphamvu zake zapamwamba, kulimba kwake komanso kugwiritsa ntchito bwino ndalama. Mu blog iyi, tifufuza kufunika kwa mapaipi achitsulo cha kaboni olumikizidwa mozungulira mu njira yolumikizira mapaipi achitsulo, ndikufufuza momwe amapangira, zabwino zake, ndi madera ogwiritsira ntchito.

Kapangidwe ka Mankhwala

Njira zopangira

Chitoliro cholumikizidwa ndi spiral, chomwe chimadziwikanso kuti chitoliro cha SSAW (spiral submerged arc welded), chimapangidwa pogwiritsa ntchito njira zopangira spiral ndi submerged arc welded. Njirayi imayamba ndi kukonza m'mphepete mwa chingwe chachitsulo cholumikizidwa kenako ndikupindika chingwecho kukhala mawonekedwe ozungulira. Kenako cholumikizira chokha cha arc chomwe chimayikidwa ndi madzi chimagwiritsidwa ntchito kulumikiza m'mphepete mwa zingwezo pamodzi, ndikupanga weld yopitilira kutalika kwa chitolirocho. Njirayi imatsimikizira kuti cholumikiziracho ndi cholimba komanso cholimba pomwe chimachepetsa zolakwika ndikusunga umphumphu wa kapangidwe kake.

Ubwino wa chitoliro chachitsulo cha kaboni cholumikizidwa mozungulira

1. Mphamvu ndi kulimba:Chitoliro chachitsulo cha kaboni chozungulira cholumikizidwaimadziwika ndi mphamvu zake zapamwamba komanso kulimba kwake, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito zomwe zimafuna kukana kuthamanga kwambiri komanso kugwira ntchito kwa nthawi yayitali.

2. Kusunga Mtengo: Mapaipi awa amapereka njira yotsika mtengo chifukwa cha njira yawo yopangira zinthu, kuchepetsa ndalama zopangira, komanso kuchepa kwa ntchito poyerekeza ndi mitundu ina ya mapaipi.

3. Kusinthasintha: Kusinthasintha kwa chitoliro cha chitsulo cha kaboni cholumikizidwa mozungulira kumalola kuti chigwiritsidwe ntchito m'njira zosiyanasiyana, kuphatikizapo mayendedwe amadzi, mayendedwe amafuta ndi gasi, nyumba zomangira, machitidwe a zinyalala, ndi njira zosiyanasiyana zamafakitale.

4. Kulondola kwa miyeso: Njira yopangira zozungulira imatha kuwongolera molondola kukula ndi makulidwe a khoma la chitoliro, kuonetsetsa kuti kupanga ndi kolondola komanso kofanana.

Madera ogwiritsira ntchito

1. Makampani Opanga Mafuta ndi Gasi Wachilengedwe: Mapaipi achitsulo cha kaboni opangidwa ndi spiral welded amagwiritsidwa ntchito kwambiri mumakampani opanga mafuta ndi gasi wachilengedwe, makamaka ponyamula mafuta osakonzedwa, gasi wachilengedwe ndi zinthu zamafuta. Mphamvu zawo komanso kuthekera kwawo kupirira malo opanikizika kwambiri zimapangitsa kuti zikhale zabwino kwambiri pamapaipi akutali.

2. Kutumiza Madzi: Kaya ndi ntchito yopereka madzi kwa anthu am'deralo kapena yothirira, mapaipi achitsulo cha kaboni olumikizidwa ndi spiral amapereka yankho labwino kwambiri chifukwa cha kukana dzimbiri, mphamvu komanso kusavuta kuyika.

3. Thandizo la kapangidwe ka nyumba: Mtundu uwu wa chitoliro umagwiritsidwa ntchito kwambiri mumakampani omanga kuti upereke chithandizo cha kapangidwe ka nyumba, milatho, madoko ndi mapulojekiti ena a zomangamanga. Kulimba kwawo komanso kukana zinthu zakunja zimapangitsa kuti zikhale zodalirika pa ntchito zotere.

4. Ntchito Zamakampani: Mapaipi achitsulo cha kaboni opangidwa ndi spiral amagwiritsidwa ntchito m'magawo osiyanasiyana amafakitale monga kukonza mankhwala, malo opangira magetsi ndi ntchito zamigodi chifukwa cha kuthekera kwawo kuthana ndi kutentha kwambiri, kupsinjika ndi malo owononga.

Pomaliza

Chitoliro chachitsulo cha kaboni cholumikizidwa mozungulira, mongaChitoliro cha X42 SSAW, yasintha kwambiri njira yowotcherera mapaipi achitsulo, zomwe zabweretsa zabwino zambiri ku mafakitale osiyanasiyana. Mphamvu zawo, kulimba kwawo, kugwiritsa ntchito bwino ndalama zawo komanso kulondola kwawo kumatsimikizira kuti kapangidwe kawo ndi koyenera pa ntchito zosiyanasiyana. Kutha kupirira kupsinjika kwakukulu, kutentha ndi malo owononga kumapangitsa kuti ikhale yoyenera kutumiza mafuta ndi gasi, kupereka madzi ndi magawo ena a mafakitale. Chifukwa chake, pankhani yowotcherera mapaipi achitsulo, kugwiritsa ntchito mapaipi achitsulo a kaboni olumikizidwa ndi spiral kumakhalabe njira yodalirika komanso yothandiza yotsimikizira kuti zomangamanga zimakhala zolimba komanso zolimba.

Mayeso a Hydrostatic

Kutalika kulikonse kwa chitoliro kuyenera kuyesedwa ndi wopanga ku mphamvu ya hydrostatic yomwe ingapangitse kuti pakhoma la chitoliro pakhale mphamvu yosachepera 60% ya mphamvu yocheperako yopezeka pa kutentha kwa chipinda. Kupanikizika kuyenera kutsimikiziridwa ndi equation yotsatirayi:
P=2St/D

Kusintha Kovomerezeka kwa Kulemera ndi Miyeso

Kutalika kulikonse kwa chitoliro kuyenera kuyezedwa padera ndipo kulemera kwake sikuyenera kupitirira 10% kapena 5.5% pansi pa kulemera kwake kongopeka, kuwerengedwa pogwiritsa ntchito kutalika kwake ndi kulemera kwake pa unit level.
M'mimba mwake wakunja suyenera kusiyana kuposa ± 1% kuchokera m'mimba mwake wakunja wotchulidwa
Kukhuthala kwa khoma nthawi iliyonse sikuyenera kupitirira 12.5% ​​pansi pa makulidwe a khoma omwe atchulidwa
