Dab tsi yog X52 cov khoom sib npaug rau - Kev Paub

API 5L X52 yog dab tsi?

X52 roj pipeline yeeb nkab yog ib qho kev lag luam yeeb nkab ua los ntawm cov pa roj carbon steel, ua los ntawm cov txheej txheem kub - dov. Nws feem ntau yog siv los thauj cov pa roj, dej, thiab roj hauv kev lag luam roj thiab ntuj. Nws cov qauv suav nrog GB / T9711.1 thiab API SPEC 5L. Cov kev qhia tshwj xeeb muaj xws li txoj kab uas hla ntawm 34-3500mm thiab phab ntsa thicknesses ntawm 3.0-60mm. Cov kev sib txuas muaj xws li vuam, coupling, thiab cov pob qij txha.

X52 cov khoom sib npaug yog dab tsi?

API 5L's X52 sib raug rau qib L360, nrog qhov tsawg kawg nkaus tawm los ntawm 360 MPa.

Dab tsi yog phab ntsa thickness ntawm API 5L X52?
