API 5L X42 PSL1 Thiab PSL2 Weded Pipes piav qhia
Lub npe ntawm X42 pipeline tubing ua raws li API 5L tus qauv. Ntawm no, "X" qhia tias cov khoom ntawm cov raj xa dej yog cov hlau, thiab "42" sawv cev rau nws qhov kev tawm dag zog tsawg kawg nkaus nyob rau hauv units ntawm ntau txhiab phaus ib square inch (42 ksi), uas hloov mus rau kwv yees li 290 MPa hauv thoob ntiaj teb units. Cov qib steel no xav tau cov raj xa dej kom tswj tau qhov zoo ntawm weldability thiab formability thaum ua kom muaj zog, ua tau raws li kev tsim kho cov kev xav tau ntawm cov kav xa mus ntev -.

Cov txheej txheem kev ua tau zoo ntawm API 5L X42 steel yeeb nkab
X42 tubing tubing yuav tsum tau kuaj hydrostatic, nrog rau kev ntsuas siab ntsuas raws li cov yeeb nkab kab, phab ntsa thickness, thiab qib steel, kav ntev li 5 vib nas this. Tsis tas li ntawd, yuav tsum tsis yog - kev sim ua kom puas tsuaj, suav nrog kev kuaj ultrasonic lossis kev ntsuas tam sim no, kom ntseeg tau tias lub raj tsis muaj qhov tsis xws luag. Qhov kawg kev npaj yuav tsum muaj xws li beveling thiab chamfering kom lav qhov zoo ntawm qhov chaw vuam.
Nto zoo thiab cim cov cai ntawm API 5L X42 welded kab yeeb nkab
Tubing nto yuav tsum du thiab tiaj, tsis muaj qhov tsis xws luag xws li tawg, folds, lossis nti. Cov khawb me me los yog cov dents tau tso cai, tab sis lawv qhov tob yuav tsum tsis pub tshaj 12.5% ntawm nominal phab ntsa thickness. Txhua lub raj yuav tsum raug cim nrog cov ntaub ntawv suav nrog cov chaw tsim khoom lub npe, qib steel X42, qhov ntev, tus lej API 5L, thiab tus lej batch.
Ntim thiab shipping
Qhov kawg ntawm X42 welded tubing yuav tsum tau nruab nrog lub tes tsho tiv thaiv kom tsis txhob muaj kev puas tsuaj rau lub beveling thaum lub caij tsheb thauj mus los. Kev tiv thaiv - kev ntsuas corrosion yuav tsum tau ua thaum lub sijhawm thauj mus los thiab khaws cia kom tsis txhob xeb ntawm lub raj.
