Daim ntawv thov ntawm Expansion Joints nyob rau hauv Gas Pipelines:
Gas pipelines, tshwj xeeb tshaj yog cov rau tus kheej - muaj gasifiers thiab kilns, muaj kev nthuav dav thiab contraction loj vim lub tshav kub generated los ntawm cov roj nws tus kheej. Qhov kev nthuav dav thiab kev cog lus no tuaj yeem ua tau ntau yam raws li cov pa kub hloov pauv. Yog li ntawd, kev txhim kho cov pob qij txha txuas ntxiv yog qhov tseem ceeb los txo cov kav dej thiab kev sib zog. Cov khoom siv nthuav dav thiab cov pob qij txha nthuav dav kuj tau nquag nruab rau hauv cov kav dej ntawm cov chaw nres tsheb roj txias hauv qhov ntev kom txo tau qhov nro los ntawm thermal expansion thiab contraction.
Expansion pob qij txha kuj siv nyob rau hauv offshore roj thiab roj drilling, piv txwv li, nyob rau hauv cov dej tob drilling riser systems. Xyoo 2026, CNOOC (Tuam Tshoj National Offshore Oil Corporation) tau siv cov khoom siv sib txuas ntxiv hauv nws qhov 1500-meter tob-dej drilling riser system.
