erw welded bir tollayn tuubada efw tuubada gaaska
Inta lagu jiro alxanka tuubada ERW, kulaylku waxa uu dhashaa marka hadda uu dhex socdo dusha xidhiidhka ee aagga alxanka. Waxay kuleylaysaa labada gees ee birta ilaa barta uu gees ka samaysan karo curaarta. Isla mar ahaantaana, iyada oo la raacayo ficilka cadaadiska isku dhafan, cidhifyada tuubada ee bannaan ayaa dhalaalay oo wada tuujiya.
Caadiyan tuubooyinka ERW ugu badnaan OD waa 24” (609mm), tuubooyinka cabbirka waaweyn waxaa lagu soo saari doonaa SAW.
Waa maxay nooca tuubooyinka (heerarka) ee lagu samayn karo hababka ERW?
Waxaa jira tubooyinka badan oo ay soo saari karto habka ERW:

Soo noqnoqoshada tooska ah ee tolitaanka tooska ah ee korantada-iska caabinta welded birta (erw birta birta) waa gariirad kulul ka dib samaynta mishiinka, isticmaalka saamaynta maqaarka ee soo noqnoqda sare ee hadda jira iyo saamaynta u dhowaanshaha, kuleylka cidhifka tuubada iyo dhalaalka, tuujin rullaluistemadka hoosta alxanka cadaadiska si loo gaaro wax soo saarka.
Tuubbooyinka alxanka caabbinta-sare ee alxanka, tuubada alxanka iyo habka alxanka caadiga ah ma aha isku mid, alxanka wuxuu ka samaysan yahay dhalaalidda birta saldhigga ah ee jirka, xoogga farsamada ayaa ka fiican tuubada guud. Muuqaal siman, sax sare, alxanka qiimaha jaban iyo mid yar, daahan 3PE-daxalka wanaagsan Waxaa jira farqi weyn oo u dhexeeya hababka alxanka ee u dhexeeya tuubooyinka alxanka ee soo noqnoqda ee soo noqnoqda iyo tuubada alxanka ee quusta. Maadaama alxanka isla markiiba lagu sameeyo xawaare sare, dhibka lagu hubinayo tayada alxanka ayaa aad uga sarreeya kan alxanka quuska ah.
