Qaab dhismeedka alxanka tuubada ERW
Marka loo eego heerarka API SPEC 5L, inta badan warshadda wax-soo-saarka gudaha inta lagu jiro tijaabada tuubada alxanka ee SAW, inta badan waxay xajisaa xoojinta alxanka, tijaabada xajinta tooska ah ee tijaabada ah marar dhif ah ayay jabisay xaaladda alxanka.Sababta ugu weyn waxaa loo aaneyn karaa joogitaanka xoojinta alxanka.Dhuumaha SAW, ayaa sheegay in ka badan sare ama xoojinta sare, in ujeedada si loo kordhiyo dhumucda aagga alxanka, iyo kor loogu qaado xoogga qaab dhismeedka alxanka, xoogga aagga alxanka (xoogga guud ee dhismaha) ka badan xoogga saldhigga qaybo bir ah.
Tixraaca alxanka tuubada SAW Xoojinta doorka faa'iidada leh ee alxanka tuubada ERW Weld wuxuu ku talajiraa inuu tuujiyo dhumucdiisuna, agagaarka alxanka si uu u sameeyo dhumuc ka weyn dhumucda alaabta salka, oo ku fidsan lakabka xoojinta aagga kulaylka-saameeyey, ka dibna gudaha formation Burr alxanka gebi ahaanba evenness, samaynta gobolka kala guurka siman mawjadaha si loo hagaajiyo xoogga qaabdhismeedka aagga alxanka dhexeeya biraha salka iyo alxanka birta.Dhanka kale, tan iyo dhumucda alxanka tuubooyinka waxay leeyihiin dulqaad weyn, xitaa xoqida xasilloonida nidaamka qallafsanaanta gudaha, taasoo keentay heer ka mid ah alxanka jeexjeexyada xoqidda, ma keeni doonto hoos u dhac weyn oo xoogga alxanka ah.Intaa waxaa dheer, alxanka iyo birta salka u wareejinta siman, baaritaanka ultrasonic ee alxanka ma keeno kordho heerka togan been abuur ah.
Ku xoq alxanka gudaha oo aad u siman burr, alxanka iyo kala guurka birta saldhig aad u siman.Caadi ahaan dhumucdiisuna waxay tahay 11.9mm, dhumucdiisuna waxay u dhaxaysaa 25mm ilaa labada dhinac ee alxanka kasta, qaybta alxanka ka dib marka la saaro burr marka loo eego qaybaha kale ee dhumucdiisuna waxay salka ku saabsan 10%.Dhumuc yar oo tuubada ah, tuujin kala duwanaansho qaro weyn ayaa laga yaabaa in la yareeyo, laakiin saamiga qaybaha dhumucda alxanka ee xakamaynta guud 10% dhumucda alaabta saldhigga.
