Dhuumaha API 5L X70 waa agab tuubooyin heersare ah oo ku jira tilmaamaha caadiga ah ee API 5L. Waxa kale oo loo yaqaan tubbada L485, maadaama ay ugu yar tahay awoodda 485 Mpa (70,300 psi). API 5L X70 waxa ay dabooshaa noocyada wax soo saarka ee kuwa aan xidhnayn iyo kuwa alxanka leh (ERW, SAW), oo labaduba lagu codsado gudbinta saliidda iyo gaaska.

Dhamaadka tuubada API 5L X70 PSL2
Dhamaadka tuubooyinka waa siman yihiin, oo aan lahayn dun.
Laga soo bilaabo 60.3 dhexroor ayaa la goynayaa iyadoo loo eegayo heerarka:
DIN, EN – a = 40° – 60°, c = ilaa 2 mm
ASME – a = 75° ± 5°, c = 1,6 ± 0,8 mm
Calaamadaynta API 5L X70 PSL2 xidhmooyinka tuubooyinka iyo tuubooyinka
Tuubooyinka dhexroorkoodu yahay ilaa 1 ½” ayaa lagu calaamadeeyay xirmada. Tuubooyinka dhexroorkoodu ka weyn yahay 1 ½” ayaa loo fuliyaa si waafaqsan awaamiirta ama marka la codsado.
API 5L X70 PSL2 Pipe - ilaalinta dusha sare
Tuubooyinka laynka ayaa la keenaa iyada oo aan si ku meel gaar ah looga ilaalin daxalka. Marka la codsado, waxaa suurtogal ah in la keeno tubooyinka ilaalinta daxalka ee lagu heshiiyey. Cidhifyada tuubada waxaa lagu xidhi karaa balaastig ah.
