API 5L Qib X65 PSL2 ERW Pipe
API 5L Qib X65 PSL2 ERW Pipe(Electric Resistance Welded) yog qib siab -strength kab yeeb nkab qib. Nws yog tsim los ntawm cua sov cov npoo ntawm ib tug steel kauj siv high - zaus tam sim no thiab ces mechanically nias lawv ua ke los tsim ib tug longitudinal weld.
X65sawv cev rau qhov tsawg kawg nkaus yield zog ntawm65,000 psi (450 MPa).
PSL2qhia tau hais tias cov yeeb nkab ua tau raws li Cov Khoom Qhia Tshwj Xeeb Qib 2, uas suav nrog qhov yuav tsum tau ua kom muaj kev sib tw toughness, stricter tshuaj muaj pes tsawg leeg tswj, thiab tag nrho cov cua sov traceability.
ERW (HFW)txheej txheem muaj qhov zoo xws li cov phab ntsa tuab tuab, zoo heev roundness, thiab siab ntau lawm efficiency, ua rau nws zoo tagnrho rau nruab nrab - mus rau - txoj kab uas hla loj roj thiab roj sib sau ua ke thiab faib kab.

FAQ
Qhov txawv ntawm ERW yeeb nkab thiab cov yeeb nkab ib txwm yog dab tsi?
ERW cov kav dej yog tsim los ntawm dov thiab vuam steel strips, uas ua rau muaj qhov ntev ntawm weld seam. Lawv muabCov nqi qis dua, kev ua haujlwm siab dua, thiab cov phab ntsa tuab heev, ua rau lawv zoo tagnrho rau cov qauv nruab nrab - mus rau - kev thauj mus los tsis tshua muaj siab. Nyob rau hauv sib piv, "ib txwm" seamless kav yog tsim los ntawm piercing khoom steel billets thiab muajtsis muaj weld seam kiag li; lawv muab cov qauv zoo sib xws thiab tuaj yeem tiv taus qhov kub thiab txias, ua rau lawv zoo dua haum rau siab -kev nyab xeeb, kev ua haujlwm tseem ceeb.
Qhov txawv ntawm API 5L X60 thiab X65 yog dab tsi?
Thawj qhov sib txawv ntawmAPI 5L X60thiabAPI 5L X65yog lawvyield zog. X65 yog kwv yees8% muaj zog duatshaj X60, uas tso cai rau cov engineers los tsim cov kav dej uas muaj qhov siab dua lossis cov phab ntsa nyias nyias kom txuag tau cov khoom siv thiab cov nqi thauj khoom.
