Flat RUBBER GASKET

ساختار محصول

گسکت های لاستیکی فلت- فیس ( با رویه مسطح) عمدتا در کاربردهایی با فشار و دمای پایین مورد استفاده قرار می گیرند. رنج فشاری حداکثر 16 بار و دمای حداکثر 12 درجه سانتی گراد مطلوب این گسکت ها هستند که به گرید لاستیک استفاده شده بستگی دارند. مقاومت شیمیایی به شدت به کیفیت لاستیک بستگی دارد. گسکت های لاستیکی اغلب در فلنج های فول-فیس مورد استفاده قرار می گیرند. قطر بیرونی این گسکت ها برابر است با قطر بیرونی فلنج و در این نوع گسکت ها برای پیچ ها سوراخ تعبیه شده است. گسکت های لاستیکی یا رابر در فشار های پیرامونی بسیار کم (2 n/mm2) آب بندی بسیار خوبی را ارائه داده و می توانند تا حجم باری تقریبی 10 n/mm2 را تاب بیاورند.
