Spiral yakakundwa Arc Weld Pipe mu API 5L Line Pipe application
The theApi 5l mutsara pombiStandard ndeyekutaurwa kwakagadzirwa neAmerican Petroleum Institute (API) yekufambisa yegesi rechisikigo, mafuta nemvura. Iyo inoburitsa zvinodiwa zvekugadzira zvibayiro zvesimbi uye inoisa zviyero zvakasimba zvemhando, simba uye kuita kweiyi pombi idzi.

SSAW PIPEYakagadzirwa uchishandisa yakanyungudutswa Arc Tilding maitiro ayo anosanganisira kugadzira coil yesimbi muchimiro chakatenderedza uye wozoshandisa testing arc kuti fuse mipendero yeiyo coil pamwe chete.
Chimwe chezvakanyanya zvakanakira kushandisa spiral yakakundwa Arc yeARC Pipi mu API 5L Line application ndiko kugona kwavo kwekunetseka kwemukati nekumanikidza kwekunze. Izvi zvinonyanya kukosha mumafuta egasi negesi, uko mapipi anofumurwa kumamiriro ezvinhu akanyanya uye mitoro inorema. Kuvakwa kwakasimba kwemiupa yeSsaw kunoita kuti ive yakakodzera pipi pombi inoshanda pakumanikidza nekupisa, ichipa mhinduro yakavimbika uye yekupedzisira yekufambisa yezvinhu zvakakosha zviwanikwa.
Uye zvakare, kuchinjika kwekupfava kwakarukwa ARC yeArc yakavezwa pombi inoita kuti zvive nyore kuisa uye kuchengetedza, ichiita sarudzo inoshanda pombi yemapipi. Kugona kwavo kwekubhururuka uye kuwiriraniswa kune zvakasikwa zvematongerwo enyika kunobvisa kukosha kwekudhura uye nguva inodhura tsika yekugadzira uye inoderedza njodzi yekukora uye kutadza. Pamusoro pezvo, iyo yakatsiga yemukati yemukati yeSsaw pombi inoderedza kupokana uye nyonganiso, zvichikonzera kuyerera kwakanyanya uye kuderera kwesimba.

Mukupfupikisa, kushandiswa kweSpiral yakakundwa Arc Yakatemwa Pombi mu API 5l Line Application inopa nhevedzano yakanakira iyo inogadzira indasitiri inoyevedza yeaini negesi. Simba ravo, kushanduka kwavo uye kushanduka kunovaita kuti vazive kuti vashandiswe munzvimbo dzinoda kuisirwa, nepo kuisirwa mari yekuisa uye yekugadzirisa mari inopa mhinduro-inobudirira yekuvaka mapiritsi ekuvaka.
