Habka wax-soo-saarka ee Tuubbada alxanka leh ee Dhererka ah:

Dhuumaha LSAWqaata tignoolajiyada alxanka arc quuska ah, iyada oo la adeegsanayo alxanka buuxinta, qulqulka ilaalinta walxaha arc aasay.

LSAW waa soo gaabinta Ingiriisida ee dhuumo bir ah oo tol ah oo toosan.Habka wax soo saarka ee tuubada birta tolsan ee toosan ee arc waxaa ka mid ah tignoolajiyada samaynta JCOE, gariiradda samaynta tignoolajiyada alxanka quuska iyo farsamada samaynta UOE.

Habka soo saarida Dhuumaha Dhererka Submerged-Arc Welded(LSAW) waa sida soo socota:

Baadhitaanka saxanka Ultrasonic → shiidista cidhifka → hore u laabashada → samaynta → alxanka ka hor → alxanka gudaha → alxanka dibadda → Kormeerka Ultrasonic → Kormeerka raajada → Kordhinta → tijaabada hydraulic →l.Chamfering → Kormeerka Ultrasonic → Baaritaanka raajada → Baaritaanka walxaha magnetic ee dhamaadka tuubada

Baaritaanka Hydrostatic

Tijaabada NDT(RT)

Tijaabada NDT(UT)

Tijaabada laabta-Dherer ku filan oo tuubo ah waa in ay istaagtaa iyadoo qabow ilaa 90° oo ku wareegsan meeraha cylindrical.

Tijaabada fidsan-inkasta oo aan tijaabada loo baahnayn, tuubooyinku waa inay awoodaan inay buuxiyaan shuruudaha tijaabada.

Baaritaanka Hydro-static-marka laga reebo sida loo ogol yahay, dherer kasta oo tuubo ah waa in lagu sameeyaa tijaabada hydrostatic iyada oo aan la daadin darbiga tuubada.

Tijaabada koronto ee aan burbursanayn-Beddelka tijaabada hydro-static , jirka buuxa ee tuub kasta waa in lagu tijaabiyaa tijaabo koronto oo aan burbursanayn .Halka lagu sameeyo tijaabada koronto ee aan burbursanayn, dhererka waa in lagu calaamadiyaa xarfaha"NDE"

Dulqaadka dhexroorka dibadda, dhumucda gidaarka, dhererka iyo miisaanka:

Dhexroor ka baxsan	Dhexroorka ka baxsan tuubooyinka tuubooyinka waa in aanay ka duwanaan doonin wax ka badan ±1% dhexroorka dibadda ee la cayimay.
Dhumucda gidaarka	Dhumucdiisuna waxay tahay waa in aanay ka badnayn 12.5% oo hoos timaada dhumucda darbiga magaca ee la cayimay.
Dhererka	Tusmada tuubooyinka waa in lagu gogladaa dherer random ah, labanlaab random dhererka, ama dhererka lebbiska sida lagu qeexay nidaamka iibka, iyadoo la raacayo xuduudaha soo socda:	Dherer aan kala sooc lahayn oo keli ah	16 ilaa 25ft (4.88 ilaa 7.62mm), inji
		Dhererka labanlaaban ee random	In ka badan 25ft (7.62m) oo leh celceliska ugu yar ee 35ft (10.67m)
		Dhererka lebbiska	dhererka sida lagu qeexay kala duwanaanshaha la ogol yahay ee ±1 in.
Miisaanka	Dherer kasta oo tuunsan tuubooyinka waa in si gaar ah loo miisaamaa oo miisaankeedu waa in aanu ka duwanayn 15% in ka badan ama 5% marka la eego miisaankeeda aragtiyeed, iyada oo la xisaabinayo iyada oo la isticmaalayo dhererkeeda iyo miisaankeeda dhererka halbeeg kasta.
