L360 kab yeeb nkab yog qhov nruab nrab - mus rau - siab zog seamless steel yeeb nkab ua raws li lub teb chaws tus qauv GB / T 9711 los yog API SPEC 5L specifications. Nws yog dav siv nyob rau hauv cov roj thiab roj tsheb thauj mus los, hauv nroog gas pipelines, cua sov pipelines, thiab industrial fluid tsheb thauj mus los systems. "L" sawv cev rau kab yeeb nkab, thiab "360" qhia nws qhov tsawg kawg nkaus yield zog ntawm 360 MPa. Cov yeeb nkab steel no muaj cov khoom siv zoo heev, weldability, thiab corrosion kuj, ua rau nws haum rau ntev - thauj mus los nyob rau hauv nruab nrab - mus rau - qhov chaw siab.
Nws cov yam ntxwv tseem ceeb muaj xws li:
1. Qhov sib npaug ntawm lub zog siab thiab tawv tawv: Thaum ua kom lub zog tensile (feem ntau ntau dua lossis sib npaug ntawm 460MPa), nws yuav tsum ua kom tau raws li Charpy cuam tshuam cov kev xav tau ntawm -20℃lossis qis dua kub los tiv thaiv kev tawg ntawm cov kav dej hauv qab qhov kub thiab txias ib puag ncig.
2. Kev tiv thaiv corrosion: Los ntawm kev ntxiv cov ntsiab lus alloying xws li Cu, Cr, thiab Ni, nws cov kev tiv thaiv rau hydrogen sulfide (H₂S) thiab carbon dioxide (CO₂) corrosion yog txhim kho, ua rau nws tshwj xeeb tshaj yog haum rau cov roj thiab roj tsheb thauj mus los uas muaj corrosive media.
3. Weldability zoo heev: Cov pa roj carbon sib npaug (Ceq) tswj tau qis dua 0.43%, kom ntseeg tau tias qhov txias txias tsis yooj yim tsim thaum lub sijhawm ntawm - qhov chaw vuam, yoog raws li kev tsim kho.
L360 Line Pipe Application Area
L360 yog siv dav hauv cov teb hauv qab no:
Kev Lag Luam Roj thiab Roj: Rau cov roj thiab cov kav dej, suav nrog cov kav dej hiav txwv thiab cov kav dej.
Kev Lag Luam Tshuaj: Rau cov cuab yeej siv tshuaj, cov tso tsheb hlau luam, thiab cov reactors, vim nws zoo heev corrosion kuj.
Kev tsim vaj tsev thiab kev tsim vaj tsev: Rau cov txuas hniav, lub tsev tsim, thiab lwm yam, vim nws lub zog siab thiab zoo heev weldability.
