ASME B16.20 , استاندارد گسکت های فلزی

دانلود استاندارد ASME B16.20 ویرایشهای مختلف جدید و قدیمی ( استاندارد گسکت های فلزی برای فلنج های پایپینگ )

ASME B16.20 , استانداردی بسیار کاربردی در لوله کشی صنعتی در صنایع نفت و گاز و پتروشیمی به شمار میرود.
این استاندارد به بررسی ملزومات کیفی و ابعاد و الزامات ساخت و متریال گسکت (آب بند) های فلزی مورد استفاده در فلنج های پایپینگ، شامل گسکت های رینگ جوینت (Ring-Joint) ، اسپیرال ووند (Spiral-Wound) ، و جاکتی (Jacketed) ، می پردازد.
