Habka Wax Soo Saarka Tuubooyinka Alxanka ee Dhererka leh ee la dhex geliyo:

Tuubada LSAWwaxay qaadataa tignoolajiyada alxanka qaansada ee biyaha hoostooda ku jira, iyadoo la adeegsanayo alxanka buuxinta, qaansada lagu aasay qulqulka ilaalinta walxaha.

LSAW waa soo gaabinta Ingiriisiga ee tuubooyinka birta tolmada toosan ee arc-ka ee biyaha hoostooda ku jira. Habka wax soo saarka ee tuubooyinka birta tolmada toosan ee arc-ka ee biyaha hoostooda ku jira waxaa ka mid ah tiknoolajiyada sameynta JCOE, tiknoolajiyada alxanka qulqulka ee biyaha hoostooda ku jira iyo tiknoolajiyada sameynta UOE.

Habka loo soo saaro Tuubooyinka Longitudinal Submerged-arc Welded (LSAW) waa sida soo socota:

Baaritaanka saxanka Ultrasonic → Shiididda geesaha → ka hor-laabashada → sameynta → Alxanka kahor → Alxanka gudaha → Alxanka dibadda → Kormeerka Ultrasonic → Kormeerka Raajada → Ballaarinta → Tijaabada Haydarooliga → l. Chamfering → Kormeerka Ultrasonic → Kormeerka Raajada → Kormeerka walxaha birlabta ee dhamaadka tuubada

Tijaabada Hydrostatic

Baaritaanka NDT (RT)

Tijaabada NDT (UT)

Imtixaanka Laabista—Dherer ku filan oo tuubo ah ayaa istaagi doona iyadoo qabow ilaa 90° ku wareegsan mandrel dhululubo ah.

Tijaabada fidsan-In kasta oo aan loo baahnayn tijaabinta, tuubooyinku waxay awood u yeelan doonaan inay buuxiyaan shuruudaha tijaabada siman.

Tijaabada Hydro-static—marka laga reebo sida loo oggol yahay, dherer kasta oo tuubo ah waa in lagu sameeyaa tijaabada hydro-static iyada oo aan laga daadan derbiga tuubada.

Tijaabada korontada ee aan burburin -Beddel ahaan tijaabada hydro-static, jirka oo dhan ee tuubo kasta waa in lagu tijaabiyaa tijaabo koronto oo aan burburin. Haddii tijaabada korontada ee aan burburin la sameeyo, dhererka waxaa lagu calaamadeyn doonaa xarfaha "NDE"

API 5L Soo saaraha tuubooyinka birta ah ee Kaarboon LSAW

Dulqaadka dhexroorka dibadda, dhumucda derbiga, dhererka iyo miisaanka:

Dhexroorka Dibadda	Dhexroorka dibadda ee tuulmooyinka tuubooyinka waa inaysan ka badneyn ±1% marka loo eego dhexroorka dibadda ee la cayimay.
Dhumucda derbiga	Dhumucda derbiga mar kasta waa inaysan ka badnaan 12.5% marka loo eego dhumucda derbiga magacaaban ee la cayimay.
Dhererka	Tuubooyinka tuubooyinka waa in lagu qalabeeyaa dherer aan kala sooc lahayn oo hal mar ah, dherer labanlaab ah oo aan kala sooc lahayn, ama dherer isku mid ah sida ku xusan dalabka iibsiga, iyadoo la raacayo xadka soo socda:	Dhererka hal-kala-soocid la'aanta ah	16 ilaa 25 cagood (4.88 ilaa 7.62mm), inji
		Dherer labanlaab ah oo aan kala sooc lahayn	Ka badan 25 cagood (7.62m) oo celcelis ahaan ugu yaraan ah 35 cagood (10.67m)
		Dhererka isku midka ah	dhererka sida ku cad kala duwanaansho la oggol yahay oo ah ±1 inji.
Miisaanka	Dherer kasta oo tuulmo tuubo ah waa in si gaar ah loo miisaamaa miisaankeeduna kama duwana 15% ama 5% miisaankiisa aragtiyeed, iyadoo la xisaabinayo dhererkiisa iyo miisaankiisa dhererkiisa halbeeg.
