Cov pa kub ntau ntawm L360 pipeline yog -20 degree txog 121 degree . Nyob rau hauv qhov ntsuas kub no, L360 pipeline tuaj yeem ua haujlwm ib txwm thiab tiv taus qee qhov kev ua haujlwm siab. Qhov no ua rau L360 pipeline yog cov khoom siv zoo tshaj plaws rau ntau qhov haujlwm engineering.
Rau cov ntawv thov kub qis, L360 cov kav dej tuaj yeem siv tau ntawm qhov kub hauv qab -45 degree . Qhov no ua rau L360 pipeline zoo heev rau cov roj thiab roj rho tawm hauv cov chaw txias. Nyob rau hauv ib puag ncig uas tsis muaj qhov kub thiab txias, L360 pipeline tuaj yeem tswj tau nws cov khoom siv zoo thiab kev tiv thaiv corrosion los xyuas kom muaj kev nyab xeeb ntawm cov kav dej.
Nyob rau hauv cov nqe lus ntawm kev siv kub kub, qhov tseem ceeb strain kub ntawm L360 pipeline yog 538 degree. Thaum qhov kub no dhau lawm, L360 cov raj xa dej tuaj yeem ua rau cov yas deformation, uas cuam tshuam rau nws lub zog ntawm cov qauv. Yog li ntawd, thaum siv L360 pipeline nyob rau hauv qhov kub thiab txias ib puag ncig, kev ntsuas yuav tsum tau coj los txo qhov kub los yog xaiv lwm yam khoom siv.
Cov khoom tseem ceeb ntawm L360 pipeline muaj xws li carbon, silicon, manganese, phosphorus thiab sulfur. Ntawm lawv, carbon yog lub ntsiab alloying, uas tuaj yeem txhim kho lub zog thiab hardness ntawm steel; silicon thiab manganese tuaj yeem txhim kho lub zog thiab toughness ntawm hlau; phosphorus thiab sulfur cov ntsiab lus yuav tsum tau tswj nyob rau theem qis kom ntseeg tau tias cov weldability thiab corrosion kuj ntawm steel 3. Cov khoom xyaw no ua rau L360 pipeline yeeb nkab muaj lub zog siab, zoo toughness thiab zoo heev corrosion kuj, thiab tuaj yeem ua haujlwm ruaj khov hauv qhov kub thiab txias.
