API 5L X42 welded yeeb nkab yog ib qho qis - carbon manganese steel welded yeeb nkab uas ua tau raws li cov qauv thoob ntiaj teb rau cov kav xa roj thiab roj.
Core Advantages ntawm API 5L X42 Welded Yeeb Nkab
Balanced Strength & Toughness
→ X42 signifies aYam tsawg kawg nkaus lub zog ntawm 42,000 psi (~ 290 MPa). Qhov nruab nrab -lub zog no muaj qhov ua kom pom kev ua haujlwm siab thiab qis- qhov kub thiab txias, zoo tagnrho rau cov kav dej hauv hiav txwv / ntiav dej hiav txwv.
→ Cov pa roj carbon-manganese steel muaj pes tsawg leeg (C Tsawg dua lossis sib npaug li 0.28%) ua kom cov weldability zoo heev nrog kev pheej hmoo tawg tsawg.
Rigorous Quality Control
→ Ua raws li API 5L (tus qauv thoob ntiaj teb rau cov roj / cov kav dej), ua haujlwmCov tshuaj muaj pes tsawg leeg, kev sim tshuab, kev sim hydrostatic, thiab NDE (xws li UT / RT)tiv thaiv cov kav dej tsis zoo los ntawm kev nkag mus rau kev pabcuam.
→ Muaj nyob rau hauv PSL1 (pib) thiab PSL2 (txhim kho), nrog rau tom kawg yuav tsum tau nruj me ntsis cuam tshuam toughness thiab carbon sib npaug txwv.
Nqi & Edge Edge
→ Welded kav nqi 30%-50% tsawg dua qhov sib npaug seamless thiab txhawb nqa txoj kab uas hla loj dua (feem ntau Ø114mm-Ø1422mm).
→ Kev sib txuas tsis tu ncua ua rau siab -kev tsim khoom ceev, zoo meej rau kev xa tawm ntau hauv cov kav dej ntev -.
