Core Engineering Advantages
Micro-alloyed steel refinement nrog tsawg leej faj thiab phosphorus cov ntsiab lus txhawb nqa ntev -lub sij hawm kev ncaj ncees nyob rau hauv nyuaj marine thiab dej ntsev ib puag ncig.
Grain-kev tsim kho TMCP ua kom zoo ib yam Charpy V-Txoj kev cuam tshuam lub zog qis rau -40℃rau cov dej txias thiab cov ntawv thov sab nrauv.
Tsawg carbon sib npaug (Ceq) formulations yooj yim welding ncaj qha thiab txo qhov kev pheej hmoo ntawm tshav kub- cuam tshuam cheeb tsam tawg.
Ua tiav los ntawm hydraulic leveling systems kom ua tiav nqaim tuab tolerances thiab kwv yees nto flatness rau automated CNC txiav thiab vuam.
Muab khoom raws li -rolled, normalized, los yog thermo-mechanically tswj, nrog rau xaiv Sa 2.5 txhaj tshuaj blasting thiab khw- primer txheej thaum thov.
Quality Assurance & Traceability
Ntawv pov thawj Standards:Mill Test Certificate (MTC) muab nyob rau hauv raws li EN 10204 3.1 lossis EN 10204 3.2, kos npe thiab stamped los ntawm cov ntawv pov thawj Lloyd's Register (LR) cov neeg soj ntsuam.
Cov txheej txheem kuaj:100% Ultrasonic Testing (UT) raws li ASTM A578 Qib B/C lossis SEL 072 (Muaj raws li qhov kev thov lossis ib qhov project spec); yeem Z-kev taw qhia tensile xeem (Z15/Z25/Z35) rau kev tiv thaiv-lamellar tearing kuj.
Tag nrho cov khoom Traceability:Thawj cov lej kub, batch codes, thiab official LR stamps nyuaj -stamped ntawm txhua lub phaj ua ntej tawm hauv lub Hoobkas.
Muaj peev xwm tsim khoom & xa khoom
Kev tsim khoom:Steelmaking ntawm LF (Ladle Rauv) + VD (Nqus Degassing) refining kom ntseeg tau tias cov qib qis thiab siab purity.
Processing peev xwm:Hauv -lub tsev CNC nplaim taws thiab ntshav txiav, ntug beveling, Sa 2.5 txhaj tshuaj blasting, thiab weldable primer txheej (15-25μm DFT).
Ntim & Shipping:Seaworthy export ntim nrog steel strapping, ntug tiv thaiv, thiab tiv thaiv ya raws haum rau ntim los yog tawg - tej shipping.
Peb Ua Haujlwm Li Cas: Kauj Ruam - los ntawm - Cov Txheej Txheem Kev Txiav Txim
Nug & Spec Confirmation:Xa peb qhov koj xav tau qib, qhov ntev, qhov ntau, thiab qib tshuaj ntsuam (3.1 lossis 3.2 MTC).
Technical Review & Quotation:Peb txheeb xyuas cov peev txheej dov, lub sijhawm ua haujlwm, thiab muab cov nqi sib tw FOB / CIF.
Production & LR Surveyor Ua tim khawv:Kev tsim khoom pib; LR cov kws tshawb fawb ua pov thawj cov qauv, kev sim tshuab, thiab kev tshuaj xyuas UT.
MTC Kev Tshaj Tawm & Cov Ntaub Ntawv Tshuaj Xyuas:Draft Mill Test Certificate xa mus rau tus neeg siv khoom pov thawj ua ntej lub nkoj thauj khoom.
Dispatch & Xa khoom zaum kawg:Chaw nres nkoj xa khoom, cov ntaub ntawv pov thawj kev lis kev cai, thiab thawj MTC xa nrog cov ntaub ntawv xa khoom.
