گسگت رینگ جوینت (RTJ)

ساختار محصول

گسکت های رینگ جوینت آب بندهایی فلزی برای کاربرد در دما و فشار بالا هستند که برای فلنج های با شیار حلقه ای مناسب می باشند. این نوع واشرها در صنایع نفت، گاز، پتروشیمی و ولوهای فشار بالا مورد استفاده قرار می گیرند. گسکت های رینگ جوینت برای آب بندی با تماس خطی و یا سطحی با زاویه بین فلنج مورد نظر و گسکت طراحی شده اند. از طریق اعمال فشار بر سطح آب بندی بوسیله نیروی پیچ ، فلز نرم تر (گسکت) به ساختار میکرو ذره ای متریال سخت تر (فلنج) نفوذ می کند و آب بندی بسیار کارآمد و مستحکمی را ایجاد می کند.

Products: R (Oval)

سطح تماس در نوع بیضی شکل (Oval) به صورت خطی بوده و سبب آب بندی قابل اطمینانی می گردد. این گسکت ها براساس استانداردهایAPI 6A یا ASME B16.20 طراحی شده اند و برای فلنج های بر طبق استاندارد های ASME/ANSI B16.5 مناسب هستند.
