API 5L X65 PSL2 steel yeeb nkab yog siab - lub zog kab yeeb nkab uas tsim los ntawm microalloying thiab thermomechanical tswj txheej txheem (TMCP). Lub npe "X65"hais tias qhov tsawg kawg nkaus yield zog ntawm65 ksg(kwv yees li448 MPa ua). Raws li tsab xov xwm 46th edAPI 5LStandard,X65 PSL 2Cov kav hlau steel yuav tsum ua kom tau raws li cov kev cai nruj rau cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab:
Tshuaj muaj pes tsawg leeg: Tsawg carbon tsim (C Tsawg dua lossis sib npaug li 0.12%), nrog microalloying ntsiab xws liNb, V, Ti, thiab tswj nruj me ntsis ntawm leej faj thiab phosphorus cov ntsiab lus (S Tsawg dua lossis sib npaug li 0.005%, P Tsawg dua lossis sib npaug li 0.020%) los xyuas kom meej weldability thiab corrosion kuj.
Mechanical Properties: Yield zog ntawm448-600 MPa, tensile zog Ntau dua los yog sib npaug535 MPa ua, Charpy cuam tshuam lub zog Ntau dua lossis sib npaug100 Jntawm-20 degree, thiab hardness tswj nyob rau hauv250 HV 10.
Kev ua yeeb yam tshwj xeeb: Yuav tsum dhauSSCC(Sulfide Stress Corrosion Cracking) thiabHIC(Hydrogen{0}}Induced Cracking) kev ntsuam xyuas, ua rawsNWS TM0177thiabTIAB SA TM0284cov qauv.

Kev Kho Hniav: 3PE Txheej rau 50-xyoo Ntev
3PE (Peb- Txheej Polyethylene):Cov txheej txheem kub rau cov kav dej faus, sib txuas FBE qhov adhesion nrog PE cov khoom siv tiv thaiv.
FBE (Fusion Bonded Epoxy):Zoo heev rau kev tiv thaiv corrosion thiab tshuaj lom neeg puas tsuaj.
Sab hauv:Ua kua epoxy txheej los txo kev sib txhuam thiab txhim kho kev khiav hauj lwm.
Varnish / Dub Painting:Luv -lub sij hawm tiv thaiv atmospheric corrosion thaum caij tsheb npav.
Ua kom koj lub raj xa dej ntev tshaj plaws: Peb cov txheej txheem 3PE txheej ua tau raws li DIN 30670, kom ntseeg tau tias 50+ xyoo ntawm kev pabcuam hauv cov av hnyav.
Kev Tshawb Fawb
Tsis yog -Kev Ntsuas Kev Puas Tsuaj (NDT):100% Ultrasonic (UT) los yog Radiographic (RT) kuaj ntawm welds thiab yeeb nkab lub cev.
Dimensional soj ntsuam:Kev kuaj xyuas meej ntawm OD, WT, tawm - ntawm - roundness, thiab ncaj.
Mechanical Lab:Tensile, flattening, dabtsi yog khoov, thiab coj- khoov kuaj.
Thib peb-Kev Tshuaj Xyuas Tus Kheej (TPI):Peb txhawb nqa thiab txais tos kev tshuaj xyuas los ntawmSGS, BV, Intertek, lossis Lloyd'slos muab kev thaj yeeb nyab xeeb rau koj.
Ntim & Shipping
Export Packing:Cov yeeb nkab tau ntim nrog cov hlua hlau, thiab qhov kawg tau tiv thaiv nrog hnyav - lub kaus mom yas los tiv thaiv cov xov puas thiab cov khib nyiab sab hauv.
Slings & Loading:Peb siv nylon slings kom tsis txhob khawb 3PE txheej thaum ua haujlwm crane.
Flexible Logistics:Seb nws yog Breakbulk rau txoj kab uas hla loj los yog Thawv (20ft / 40ft) rau cov qauv ntau thiab tsawg, peb optimize lub load kom txuag tau koj cov nqi thauj khoom.

FAQ
Qhov txawv ntawm API 5L X65 PSL1 thiab PSL2 yog dab tsi?
API 5L PSL1 steel kab yeeb nkab muaj qhov sib txawv ntawm qhov kawg, xws li qhov kawg, xov kawg, bevel kawg thiab tshwj xeeb coupling yeeb nkab, thaum API 5L PSL2 steel kab yeeb nkab tsuas muaj qhov kawg nkaus. API 5L PSL1 steel kav tuaj yeem tsim los ntawm ntau txoj kev vuam. Txawm li cas los xij, txuas txuas txuas ntxiv yog txwv rau Qib A25.
Qhov txawv ntawm API 5L X65 thiab X70 yog dab tsi?
API 5L X65: Siv dav hauv cov kav dej sab nrauv thiab sab nrauv uas yuav tsum muaj lub zog nruab nrab thiab zoo weldability. API 5L X70: Txaus siab rau siab - cov kav dej siab thiab cov haujlwm uas xav tau lub zog siab dua - rau - qhov hnyav piv, xws li cov kav dej sib sib zog nqus dej hiav txwv.
Lub hardness ntawm X65 yeeb nkab yog dab tsi?
X65 hauv API 5L X65 yog hais txog qib ntawm cov yeeb nkab. Tshwj xeeb, nws qhia tau hais tias cov yeeb nkab muaj qhov tsawg kawg nkaus yield zog ntawm65,300 psi (phaus ib square inch) lossis 450 MPa (megapascals).
