Are rubber asbestos boards no longer allowed to be used? ? ?

There’s no such thing; where did you hear that? The pressure vessels and ASME-compliant products we manufacture for foreign manufacturers are all sealed with asbestos rubber sheets. I’ve never heard of any problems with that

I haven’t heard of it; we’ve been using it all along. The cost of graphite is too high

May I ask: Are rubber sheets also divided into two types, those containing asbestos and those without asbestos? Thank you!

I don’t think I’ve heard of any rule prohibiting its use. However, I have heard before that it is harmful to the human body due to the presence of asbestos, and it is no longer recommended for use. The information provided is not accurate; it’s for reference only! ! :lol

We’ve been using the XB350 all along; we haven’t heard of any issues from customers!

There are no explicit regulations stating that pressure vessels cannot be used

Asbestos rubber gaskets are the most commonly used non-metallic gaskets, and they are suitable for use in connections that are not frequently disassembled, with media such as water, steam, air, and other inert gases, under conditions of moderate temperature and pressure with minimal fluctuations. Asbestos rubber sheets shall comply with the GB3985 standard for Asbestos Rubber Sheets. When selecting them, the grade should be indicated in the remarks field (generally XB350 is used; XB350 is suitable for P≤2.5MPa and t≤300℃, while XB200 is suitable for P≤0.6MPa and t≤150℃). Currently, asbestos rubber gaskets are being phased out abroad, and are being replaced by materials such as flexible graphite and ceramic fibers. Oil-resistant asbestos rubber sheets shall comply with the GB539 standard for \"Oil-Resistant Asbestos Rubber Sheets\" and are generally suitable for applications at temperatures up to 200°C. When the medium is ethylene oxide, gaskets containing asbestos must not be used. Under vacuum conditions, asbestos rubber gaskets are not allowed to be used for flange gaskets; instead, rubber washers or other types of gaskets (such as wound gaskets) are generally used.

It has not been banned domestically yet. Many ** are prohibited from use. Asbestos is carcinogenic.

I work in the field of reaction vessels. They can be used under the old GB150 standard. I heard that the new GB150 standard is about to be released; I’m not sure if their use will be prohibited

“Asbestos cannot be used because it is carcinogenic; see the State Council’s Decision on Several Issues Concerning Environmental Protection (Guo Fa 1996[31]). This was a reply I received from someone before! Then a couple of days ago I inquired about the price of gaskets, and the person who sells them said that asbestos is no longer allowed to be used.

Now it’s people-oriented; since it’s harmful to humans, it should be banned.

It’s still in use; it has a low cost, is easy to process, and can be made whenever needed!

The West **banned its use a long time ago. I don’t believe it’s still allowed; I’ve been providing technical support in international trade for 4 years now, and there hasn’t been a single project in which asbestos was permitted.

I don’t think I’ve heard that it’s not allowed to use it; we’ve been using it all along

It mainly depends on where it will be used; of course, it’s not suitable for food-grade applications

Everyone says it’s harmful to the human body, so why bother considering all those costs? People don’t have this awareness, haha. If it were poison, surely no one would want it. The key point is that no one around me has ever experienced anything like this in Shanghai
