Qhov sib txawv ntawm API5LX80 Tube thiab X70 Tube
Lub ntsiab sib txawv ntawm API 5L X80 yeeb nkab thiab x70 yeeb nkab yog lawv qhov tsawg kawg yog cov tshuaj lom neeg. Cov hauv qab no yog qhov sib txawv tseem ceeb ntawm ob hom ntawm no:
Paib lub zog:
X80 Yeeb Nkab: Qhov tsawg kawg los tawm lub zog yog 80, {2}} psi (kwv yees li ntawm x80
X70 YEEB NKAUJ: Tsawg Tshaj Tawm Lub Zog Ntawm 70 2}}}} Psi (Kwvtuag Qha
Tshuaj lom neeg cov tshuaj:
Ob hom yeeb nkab muaj cov tshuaj sib txawv me ntsis, uas cuam tshuam rau lawv cov khoom siv lub cev thiab haum rau kev siv. X80 cov yeeb nkab feem ntau muaj cov ntsiab lus roj carbon ntau dua xws li Niobium (NB), vanadium (v), thiab titanium (ti) kom nce ntxiv nws lub zog thiab tawv.
X70 hlab muaj qhov sib xyaw me ntsis, feem ntau muaj cov ntsiab lus tsawg dua kom ua tiav qhov kev tshuav ntawm lub zog thiab kev sib npaug.
Cov Cheeb Tsam ntawm Daim Ntawv Thov:
X80 yeeb nkab: vim nws lub zog siab dua thiab corrosion tsis kam, x80 yeeb nkab tsis kam rau kev thauj mus los siab, xws li subss ib puag ncig, xws li subsfine pipelines thiab ncej puab ib puag ncig.
X70 YEEB: Txawm hais tias me ntsis tsis tshua muaj zog, x70 yeeb nkab tseem txaus rau cov peev txheej nruab nrab roj thiab roj kev ua haujlwm roj av, tshwj xeeb tshaj yog nyob rau hauv cov phiaj xwm nce.
