Kev lag luam roj av tsis tu ncua nrhiav cov ntaub ntawv ruaj khov tau tso titanium alloys ua cov khoom siv tsis tseem ceeb. Lawv cov khoom siv hlau tshwj xeeb daws cov teeb meem tseem ceeb hauv hydrocarbon extraction, kev ua, thiab kev thauj mus los, tshwj xeeb tshaj yog nyob rau hauv qhov chaw ua haujlwm hnyav.
Superior Material Selection rau Sour Gas Fields
Nyob rau hauv cov pa roj qaub reservoirs nrog siab H₂S thiab CO₂ ib feem ntawm lub siab, cov pa roj carbon steel pom tau sai degradation los ntawm sulfide kev nyuaj siab tawg thiab hydrogen-induced blistering. Titanium alloys, tshwj xeeb tshaj yog Pd/Ni- cov qib hloov kho, ua kom pom qhov tshwj xeeb tiv thaiv rau thaj tsam corrosion thiab cov teebmeem galvanic. Lawv cov txheej txheem oxide passive tseem nyob ruaj khov nyob thoob plaws pH ntau yam, ua rau lawv zoo tagnrho rau cov kab hauv qab thiab cov ntoo Christmas.
Offshore Pipeline Engineering Advancements
Subsea dynamic loading los ntawm yoj ua thiab vortex-vim vibrations xav tau cov ntaub ntawv uas muaj zog heev endurance. Titanium qhov qis elastic modulus thiab lub zog zoo dua - rau - qhov hnyav piv txo qhov kev ntxhov siab ntawm cov pob qij txha, thaum nws tiv thaiv chloride pitting ua kom lub neej ntev hauv dej hiav txwv immersion. Kev siv cov txheej txheem autogenous orbital vuam cov tswv yim ntxiv txhim khu kev ncaj ncees ntawm cov kav dej los ntawm kev tshem tawm cov khoom siv hlau ua kom muaj kab mob.
Cov Khoom Siv Tshuaj Txheej Txheem Ua Haujlwm Zoo
Hauv PTA (purified terephthalic acid) synthesis reactors, titanium lub siab ntev rau kub acetic acid-bromide sib tov tiv thaiv kev puas tsuaj intergranular nres pom hauv stainless hlau. Ib yam li ntawd, adipic acid ntau lawm units tau txais txiaj ntsig los ntawm titanium's nitric acid passivation tus cwj pwm, uas tshem tawm cov khoom sib kis ntawm cov khoom sib kis. Cov khoom tsis yog- cov khoom catalytic kuj tseem muaj cov tshuaj tiv thaiv purity hauv cov kab catalytic distillation.
Lifecycle Performance thiab Sustainability
Tshaj li kev tiv thaiv corrosion, titanium alloys txo tag nrho cov tswv cuab cov nqi los ntawm kev txo qis qis qis thiab ncua sijhawm tshuaj xyuas. Lawv kev sib raug zoo nrog cathodic tiv thaiv kab ke thiab tsis yog - cov khoom muaj kuab lom corrosion ua raws li cov kev cai ib puag ncig muaj zog ntxiv rau kev tshem tawm ntawm ntug dej hiav txwv.
