X65 loj- txoj kab uas hla welded yeeb nkab yog siab - lub zog kav hlau ua raws li API 5L cov qauv. Nws qhov tsawg kawg nkaus tawm lub zog yog 450 MPa (65 ksi), thiab nws yog tsim los ntawm microalloyed tswj dov thiab txias (TMCP) txheej txheem. Nws cov tshuaj lom neeg muaj pes tsawg leeg muaj cov ntsiab lus qis carbon (feem ntau Tsawg dua lossis sib npaug li 0.12%) thiab qis qis ntawm cov ntsiab lus tsis zoo xws li sulfur thiab phosphorus (tsawg dua lossis sib npaug li 0.005% thiab Tsawg dua lossis sib npaug li 0.020%, feem), txhim kho cov yeeb nkab tsis kam tiv thaiv hydrogen{{11}CCH (CCH) kev ntxhov siab).
Mechanical Properties
Cov khoom siv tsis zoo yog: yield zog Ntau dua lossis sib npaug ntawm 448MPa, lub zog tensile Ntau dua lossis sib npaug ntawm 535MPa, Charpy cuam tshuam lub zog ntawm -20℃Ntau dua lossis sib npaug rau 80J, hardness Tsawg dua lossis sib npaug rau 250HV10. Los ntawm kev tswj dov thiab cua txias tshuab, elongation ntawm so tuaj yeem ncav cuag ntau dua 30%.
Dimensional raug
Sab nraud txoj kab uas hla kam rau ua ± 0.75%, phab ntsa thickness kam rau ua 15% /-10%, ellipticity Tsawg dua los yog sib npaug rau 0.6% D, ua tau raws li qib PSL2 raws li ISO3183-2: 2019.
Environmental Adaptability
Zoo cuam tshuam toughness yog khaws cia txawm nyob rau ntawm 40 degree. Qee cov khoom tau dhau DNV-OS-F101 Arctic ntawv pov thawj. X65MS steel qib, tiv taus H2S corrosion, tau dav siv hauv sulfur -muaj cov roj av.
Nqe Ntau
Basic Specifications (piv txwv li, φ610 × 10mm): Kwv yees li RMB 5900 / tuj rau RMB 6000 / tuj (nrog rau se, lub Plaub Hlis 2024 cov ntaub ntawv);
Loj Diameter Thick-Walled Pipes (piv txwv li, φ1016 × 22mm): Nqe nce ntawm 10% mus rau 15% vim muaj zog dov nyuaj;
Customized Products (xws li Acid-Resistant X65QS): Cov nqi ntxiv ntawm kwv yees li RMB 500/ton rau RMB 800/ton.
Tus nqi tsav tsheb:
Raw Khoom Nqis: Tus nqi hloov pauv ntawm cov alloys xws li chromium thiab npib tsib xee ncaj qha cuam tshuam cov nqi;
Cov txheej txheem tsim khoom: Kub- cov kav dej dov tsis tshua kim tshaj qhov txias- cov kav dej, tab sis tom kawg yuav tsum muaj qhov siab dua;
Daim ntawv pov thawj yuav tsum tau: API 5L PSL2 ntawv pov thawj ntxiv cov kauj ruam xeem, tsav tsheb nce nqi.
