Kupititsa patsogolo Kukhulupirika Kwamapangidwe: Chitoliro Chachitsulo cha Spiral Welded Carbon mu Metal Pipe Welding Process

yambitsani

Luso lakuwotcherera chitoliro chachitsulokumafuna kuphatikiza kogwirizana kwa luso, kulondola komanso zida zabwino kuti zitsimikizire kukhulupirika kwazinthu zosiyanasiyana.Pakati pa mitundu yambiri ya chitoliro, chitoliro chachitsulo cha spiral welded carbon, monga X42 SSAW chitoliro, chimadziwika chifukwa cha mphamvu zake zapamwamba, zolimba komanso zotsika mtengo.Mu blog iyi, tiwona kufunikira kwa mapaipi achitsulo opangidwa ndi spirally welded mu njira yowotcherera chitoliro chachitsulo, ndikuwunika momwe amapangira, maubwino ndi madera ogwiritsira ntchito.

Njira yopanga

Chitoliro cha Spiral welded, chomwe chimadziwikanso kuti SSAW (spiral submerged arc welded) chitoliro, chimapangidwa pogwiritsa ntchito njira zowotcherera zozungulira komanso zomira pansi pamadzi.Njirayi imayamba ndi kukonza m'mphepete mwa mzere wachitsulo wopindidwa ndikupindika mzerewo kukhala wozungulira.Kuwotcherera kwa arc kumadzimadzi kumagwiritsidwa ntchito kulumikiza m'mphepete mwa mizere, kupanga weld mosalekeza kutalika kwa chitoliro.Njirayi imatsimikizira kuti mgwirizanowu ndi wamphamvu komanso wokhazikika pamene kuchepetsa zolakwika ndikusunga kukhulupirika kwapangidwe.

Ubwino wa ozungulira welded mpweya zitsulo chitoliro

1. Mphamvu ndi kulimba:Spiral welded carbon steel pipeamadziwika chifukwa cha mphamvu zake zapamwamba komanso zolimba, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito zomwe zimafuna kukana kuthamanga kwambiri komanso kugwira ntchito kwa nthawi yaitali.

2. Mtengo Wamtengo Wapatali: Mapaipiwa amapereka njira yotsika mtengo chifukwa cha njira zawo zopangira zopangira, zotsika mtengo zopangira, komanso kuchepetsa zofunikira za ntchito poyerekeza ndi mitundu ina ya mapaipi.

3. Kusinthasintha: Kusinthasintha kwa chitoliro cha spiral welded carbon steel pipe chimalola kuti chigwiritsidwe ntchito pazinthu zosiyanasiyana, kuphatikizapo kayendetsedwe ka madzi, kayendedwe ka mafuta ndi gasi, zomangapo, zonyansa, ndi njira zosiyanasiyana za mafakitale.

4. Kulondola kwapang'onopang'ono: Kupanga kozungulira kozungulira kumatha kuwongolera molondola kukula ndi makulidwe a khoma la chitoliro, kuwonetsetsa kulondola komanso kufanana kwa kupanga.

Malo ofunsira

1. Makampani amafuta ndi gasi: Mapaipi a chitsulo cha Spiral welded carbon steel amagwiritsidwa ntchito kwambiri m’makampani amafuta ndi gasi, makamaka ponyamula mafuta osapsa, gasi ndi zinthu zamafuta.Mphamvu zawo ndi kuthekera kwawo kupirira malo opanikizika kwambiri zimawapangitsa kukhala abwino kwa mapaipi akutali.

2. Kutumiza kwa Madzi: Kaya ndi madzi am'tauni kapena zothirira, mapaipi achitsulo opangidwa ndi spiral welded mpweya amapereka yankho labwino kwambiri chifukwa cha kukana kwa dzimbiri, mphamvu komanso kukhazikika kwake.

3. Thandizo Lamapangidwe: Chitoliro chamtunduwu chimagwiritsidwa ntchito kwambiri pantchito yomanga kuti apereke chithandizo chanyumba, milatho, madoko ndi ntchito zina zomanga.Kukhazikika kwawo komanso kukana zinthu zakunja kumawapangitsa kukhala odalirika pazogwiritsa ntchito zotere.

4. Kugwiritsa Ntchito Mafakitale: Mipope yachitsulo ya Spiral welded carbon steel imagwiritsidwa ntchito m'mafakitale osiyanasiyana monga kukonza mankhwala, magetsi opangira magetsi ndi ntchito zamigodi chifukwa cha kuthekera kwawo kuthana ndi kutentha kwakukulu, kupanikizika ndi malo owononga.

Pomaliza

Spiral welded mpweya zitsulo chitoliro, mongaChitoliro cha X42 SSAW, yasintha njira yowotcherera chitoliro chachitsulo, kubweretsa phindu lalikulu kumakampani osiyanasiyana.Mphamvu zawo, kulimba, kutsika mtengo komanso kulondola kwazithunzi zimatsimikizira kukhulupirika kwadongosolo muzogwiritsa ntchito zosiyanasiyana.Kukhoza kupirira kupsinjika kwakukulu, kutentha ndi malo owononga kumapangitsa kukhala koyenera kufalitsa mafuta ndi gasi, madzi ndi mafakitale ena.Choncho, pankhani kuwotcherera zitsulo chitoliro, ntchito ozungulira welded mpweya zitsulo mipope akadali njira yodalirika ndi kothandiza kuonetsetsa zokhalitsa ndi kupirira zomangamanga.

Kuyesedwa kwa Hydrostatic

Utali uliwonse wa chitoliro uyenera kuyesedwa ndi wopanga ku mphamvu ya hydrostatic yomwe idzapangitse mukhoma wa chitoliro kupsinjika kosachepera 60% ya mphamvu zokolola zosachepera zomwe zafotokozedwa kutentha.Kupanikizika kumatsimikiziridwa ndi equation yotsatirayi:
P=2St/D

Kusiyanasiyana Kololedwa Pakulemera ndi Makulidwe

Utali uliwonse wa chitoliro uyenera kuyezedwa padera ndipo kulemera kwake sikuyenera kupitirira 10% kuposa kapena 5.5% pansi pa kulemera kwake, kuwerengeredwa pogwiritsa ntchito kutalika kwake ndi kulemera kwake pa kutalika kwake.
Kuzungulira kwakunja sikuyenera kusiyanasiyana kupitilira ± 1% kuchokera m'mimba mwake mwadzina
Makulidwe a khoma nthawi iliyonse sayenera kupitirira 12.5% ​​pansi pa makulidwe omwe atchulidwa
