استاندارد طراحی و بازرسی مخازن کوچک آزمایشگاهی و اتصالات آنها

با سلام با توجه به اینکه در شرکت ما علاوه بر طراحی و بازرسی مخازن صنعتی لازم است که پایلوت تجهیزات طراحی و ساخته شود لطفا بفرمایید با توجه به اینکه دامنه کاری asme SEC VIII مخزن با قطر بالای 6 اینچ می باشد و تجهیزات آزمایشگاهی را نیز شامل نمی شود از چه استانداردی برای طراحی اینگونه مخازن و اتصالات آنها که تیوب می باشد باید استفاده کرد در ضمن فقط ابعاد تجهیزات کوچک می باشد اما شرایط عملکردی و سیال پروسسی همان شرایط صنعتی یا بدتر است برای مثال سیال حاوی هیدروژن یا H2S در دمای 450 درجه سانتیگراد فشار 220 بار باتشکر

ASME UM-Stamp
Difference Between U and UM
A person could correctly assume that the difference between the U designation and the UM designation is related to size. However, this is not the only difference between the two. UM designated pressure vessels are not required to undergo the same inspection regimen as the larger, U stamped pressure vessels. Additionally, U vessels are required to have a 3rd party ASME inspector review and approve the calculations as well as witness the ASME hydro test while the UM vessels do not have either of these requirements. Companies with UM stamps receive an annual audit whereas those with U stamps undergo an inspection every three years.

This does not suggest that the quality of design or fabrication is less than the larger, U designated vessels, only that the inspection requirements are not needed as often as the smaller vessels. Naturally, this does not preclude any inspection program, only that the standards for inspections are different.

The main difference between U and UM is that UM vessels are smaller in volume than U vessels, even though both size vessels can have similar operating pressures.

Some categories for UM stamped pressure vessels as listed in the ASME BPVC U-1j subset, include:

Vessels 5 Cubic Foot of volume or smaller with pressures not exceeding 250psi.
Vessels 3 Cubic Foot of volume or smaller with pressures not exceeding 350psi.
Vessels 1.5 Cubic Foot of volume or smaller with pressures not exceeding 600psi.

Because pressure vessels operate in a variety of environments and processes, it is crucial that your pressure vessel be fabricated to the highest possible standards. This applies to both large and small pressure vessels. Failure to obtain an ASME vessel can and will put your business at risk and in many cases, ASME certification is required by local regulating agencies. The ASME code was established to ensure that all aspects from design to fabrication, to operation are conducted in a safe and quality manner.
