Chidule Chathunthu cha Mafotokozedwe a Chitoliro Chozungulira Chozungulira

Yambitsani:

Mu dziko la mapaipi achitsulo,chitoliro chozungulira cholumikizidwaNdi yotchuka chifukwa cha mphamvu zake zapamwamba, kusinthasintha kwake komanso kugwiritsa ntchito bwino ndalama. Mapaipi awa amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana monga mafuta ndi gasi, kutumiza madzi, uinjiniya wamapangidwe ndi chitukuko cha zomangamanga. Kuti muwonetsetse kuti pali mgwirizano wosasunthika komanso magwiridwe antchito abwino, ndikofunikira kumvetsetsa zomwe zimalamulira chitoliro cholumikizidwa mozungulira. Mu blog iyi, tifufuza mbali zazikulu za zomwe zimafotokozera chitoliro cholumikizidwa mozungulira, kufotokoza kukula kwake, zipangizo zake ndi zofunikira zake.

1. Kukula kwa chitoliro:

Mapaipi opangidwa ndi spiral welded amapezeka m'makulidwe osiyanasiyana, zomwe zimathandiza kuti agwirizane ndi mapulojekiti osiyanasiyana. Miyeso nthawi zambiri imakhala ndi mainchesi akunja (OD), makulidwe a khoma (WT), ndi kutalika. Ma mainchesi akunja amakhala kuyambira mainchesi 20 mpaka mainchesi 120, ndipo makulidwe a khoma amakhala kuyambira 5 mm mpaka 25 mm. Ponena za kutalika, magawo wamba a mapaipi opangidwa ndi spiral welded ndi mamita 6, mamita 8, ndi mamita 12 kuti agwirizane ndi zofunikira zosiyanasiyana zaukadaulo.

2. Zipangizo:

Kusankha zipangizo za chitoliro cha SSAW n'kofunika kwambiri ndipo kumadalira makamaka momwe ntchitoyo ikugwiritsidwira ntchito komanso momwe chilengedwe chilili. Chitsulo cha kaboni chimagwiritsidwa ntchito kwambiri chifukwa cha mphamvu zake, kulimba kwake, komanso kukana dzimbiri. Kuphatikiza apo, pa ntchito zinazake zomwe zimafuna kukana dzimbiri kwambiri kapena kukana kutentha kwambiri, mapaipi opangidwa ndi chitsulo chosakanikirana, chitsulo chosapanga dzimbiri, kapena zipangizo zina zapadera angagwiritsidwe ntchito.

3. Njira yopangira:

Chitoliro cholumikizidwa mozungulira chimapangidwa kudzera mu njira yopangira mozungulira mosalekeza pogwiritsa ntchito ma coil achitsulo. Njirayi imatsimikizira kufanana kwa makulidwe a khoma, mainchesi ndi kapangidwe kake konse. Cholumikiziracho chimalowetsedwa mu makina, chomwe chimachipanga kukhala mawonekedwe ozungulira omwe mukufuna kenako chimalumikiza m'mbali. Ukadaulo wapamwamba womwe umagwiritsidwa ntchito popanga zinthu umalola kuwongolera bwino kukula ndi magwiridwe antchito a chitoliro chomaliza.

4. Miyezo yabwino:

Kuti akwaniritse miyezo yamakampani ndikuwonetsetsa kuti mapaipi olumikizidwa mozungulira ndi odalirika, njira zosiyanasiyana zotsimikizira khalidwe zimagwiritsidwa ntchito. Izi zikuphatikizapo kutsatira miyezo yodziwika padziko lonse lapansi monga API 5L, ASTM A252 ndi ISO 3183-3. Kutsatira malangizo awa kumatsimikizira mawonekedwe a makina, kapangidwe ka mankhwala, ndi kulondola kwa miyeso ya chitolirocho.

5. Kuyesa ndi kuwunika:

Kuti chitoliro cholumikizidwa ndi waya chikhale cholimba komanso chotetezeka, njira zoyesera ndi zowunikira ndizofunikira. Gwiritsani ntchito njira zoyesera zosawononga monga kuyesa kwa ultrasound, kuyesa kwa x-ray ndi kuyesa kolowera utoto. Mayesowa amazindikira zolakwika zilizonse za kapangidwe kake kapena kusagwirizana kwa zinthu zomwe zingakhudze magwiridwe antchito ndi kulimba kwa chitolirocho. Kuphatikiza apo, mayeso akuthupi monga kuyesa kwa hydrostatic amachitidwa kuti awone mphamvu ndi mphamvu ya mapaipi onyamula kupanikizika.

Pomaliza:

Mapaipi olumikizidwa ndi spiral amapereka zabwino zambiri kuposa mitundu ina ya mapaipi ndipo specifications zawo zimagwira ntchito yofunika kwambiri pakusunga khalidwe lawo, kudalirika kwawo, komanso kugwirizana ndi ntchito zosiyanasiyana. Kumvetsetsa miyeso, zipangizo, njira zopangira, ndi miyezo yabwino yogwirizana ndi spiral welded payipi ndikofunikira kwambiri kuti zitsimikizire kuti ntchito yake ndi yabwino komanso njira yotsika mtengo. Pamene ukadaulo ukupitirira kupita patsogolo, specifications zomwe zimayang'anira mapaipi awa zikupitirirabe kusintha, zomwe zikuwonjezera luso lawo komanso kusinthasintha kwawo m'mafakitale osiyanasiyana. Poganizira specifications izi, mainjiniya ndi akatswiri amatha kupanga zisankho zolondola pankhani yosankha ndi kugwiritsa ntchito spiral welded payipi pa ntchito zawo.
