Dej hiav txwv engineering steel yeeb nkab tsim thiab xaiv, specification yog raws li kev faib tawm ntawm dej hiav txwv engineering steel qauv, thiab nrog rau kev siv API (American petroleum institute), AISC (American society for steel structure), ASTM (American Society of Testing and Materials). ), ANSI (American national standard institute), ASTM (American society of testing and materials), AWS (American welding society), NACE (national Association of corrosion engineers) cov qauv thiab cov lus qhia. Kev thov rau dej hiav txwv engineering steel yeeb nkab cov ntaub ntawv, qhov tseem ceeb yog qhov yuav tsum tau ntawm steel phaj nws tus kheej, muaj cov pa roj carbon tsawg, siab zog steel, ultra-siab zog steel, stainless hlau plaub pawg. Hais txog ob lub ntsiab lus ntawm no:
(1) dej hiav txwv engineering ntawm cov khoom siv txawv teb chaws ntau heev. Qee zaum rau British steel tube thiab steel tube ntau lawm yog tshwj xeeb tshaj yog cov kev xav tau zoo. Nyob rau hauv dej hiav txwv engineering belongs rau thaj tsam tshwj xeeb ntawm cov hlau raj, 100% nws tag nrho cov yuav tsum tau rau weld ultrasonic kuaj (UT – Ultrasonictesting) thiab magnetic inspection (MT – Magnetictesting). Muaj nyob rau hauv cov qauv tseem ceeb ntawm cov yeeb nkab steel, nyob rau hauv thaj tsam ntawm 300 hli ntawm ob qhov kawg ntawm txoj hlua ntev yuav tsum 100% UT thiab MT.
(2) kev tsim cov yeeb nkab node belongs rau cov ntsiab lus tseem ceeb hauv dej hiav txwv engineering. Tshwj xeeb yeeb nkab node factories txawv teb chaws, thiab domestic yog tsim tsev. Peev xwm ntawm 52000 tons, piv txwv li, "kev phooj ywg" ntawm lub hiav txwv bohai, floating ntau lawm chaw cia khoom (FPSO, thiab cob qhia ib tug ntawm Tuam Tshoj lub sab saum toj kaum nto moo shipping) ntawm tshwj xeeb mos xwb caj npab (YOKE) lub YOKE mooring system thiab txhawb bracket, lub teeb hluav taws xob ntauwd, kev txhawb nqa lub nyoob hoom qav taub platform, thiab lwm yam. Muaj 221 nodes, kom tau raws li cov kev cai ntawm AISC, AWS. 59 km ntev pipeline (xws li chaw taws teeb tswj hydraulic raj 28 km, 119 chaw taws teeb tswj valve, tank lawj 48 txoj kev). Shipyard nyob rau hauv thiaj li yuav xyuas kom meej qhov zoo ntawm kev tsim kho, xaiv los ntawm phav phav welder kaum ob ntawm zoo heev welding, lub xeem 15 tsim nyog raws li 6 gr ntawm kev faib pawg neeg. Nyob rau hauv dej hiav txwv engineering txhawm rau tiv thaiv kom tsis txhob muaj roj thiab roj hauv qhov system, tsis yog siv cov yeeb nkab flange txuas, thiab siv argon arc vuam. Peb pawg ntawm TIG welder shipyard thiab xav tau kev cob qhia tshwj xeeb.
