Nonferrous hlau cov ntaub ntawv yog dav siv nyob rau hauv offshore roj kev loj hlob, thiaj li yuav tau txais cov khoom siv roj av nrog lub teeb yuag thiab ntev kev pab cuam lub neej. Cov ntaub ntawv nonferrous feem ntau siv hauv cov khoom siv roj av muaj xws li titanium alloy, aluminium alloy, tooj liab alloy, thiab lwm yam.
Piv nrog hlau, hlau qub, tooj liab, txhuas, thiab lwm yam khoom siv feem ntau, lub zog muaj zog tsawg, thiab muaj zog corrosion tsis kam. Nyob rau tib lub sij hawm, nws kuj muaj seawater yaig kuj, tsis-sib nqus, tsis-txias brittleness, siab suab kis coefficient, zoo sib sau, casting, vuam zog, thiab lwm yam., ua rau nws dav siv tau rau txhua yam marine engineering.
Tam sim no, Tebchaws Asmeskas, Russia, thiab Tuam Tshoj tau ua tiav txog 50 yam ntawm titanium alloys rau kev tsim kho sab nrauv. Cov qib thiab cov khoom sib xws ntawm titanium feem ntau siv rau cov khoom siv hluav taws xob offshore tau teev nyob rau hauv cov lus.
Titanium thiab nws cov alloys yog cov khoom siv zoo tshaj plaws rau kev txhim kho cov khoom siv hauv marine kev txhim kho thiab txhim kho lub peev xwm ntawm kev tsim cov ntaub ntawv marine. Nyob rau hauv cov nqe lus ntawm offshore roj kev loj hlob, titanium alloy yog tsuas yog siv nyob rau hauv risers, conical kev nyuaj siab pob qij txha, coiled kav, pressurized pipelines, drilling cuab yeej lifting li, seawater pipeline systems, txias systems, thiab tua hluav taws, thiab lwm yam.
TC4 (Ti-6Al-4V) yog dav siv nyob rau hauv offshore roj thiab roj engineering, tshwj xeeb tshaj yog nrog lub dav hlau tawg toughness thiab kev nyuaj siab corrosion puas toughness ntawm Ti － 6Al － 4VELI alloy forged los ntawm forging technology yog siab tshaj. cov zoo tib yam Ti-6Al-4V, uas tau siv dav dua.
Lub tshuab nqus dej tob tob ua los ntawm Ti-6Al-4V (GR5) titanium alloy muaj qhov tob ntsug ntawm 9200mm. Tom qab hloov cov yeeb nkab steel laum nrog lub titanium alloy laum yeeb nkab, lub zog nqa ntawm cov cuab yeej drilling yog txo los ntawm 30 feem pua, thiab lub zog torque raug txo los ntawm 30 feem pua - 40 feem pua. Cov yeeb nkab txuas ntxiv rau kev lag luam hauv qab feem ntau yog welded thiab tsim nrog rau 6 hom titanium thiab titanium alloy kav, xws li Gr2, GR7, GR9, Gr12, gr18, GR28, thiab lwm yam tam sim no, qhov siab tshaj plaws sab nraud yog 63.6mm. Coiled tubing drilling tuaj yeem txo cov nqi drilling ntau heev. Siv titanium alloy coiled tubing, lub neej qaug zog thiab corrosion qaug zog lub neej ntawm coiled tubing kuj zoo heev.
