Comparison between the Code of Practice (2008) and the Code of Practice (1999)?

Where can I download the new compliance regulations?

Is it appropriate to release the new capacity regulations? How can it be downloaded?

When were the new capacity regulations issued? This is just to gather opinions for now.

Which European standards or regulations are referenced by the new Container Code regarding the classification of containers?

The EU classification of pressure vessels is based solely on the PV product; for example, those with a PV value greater than 3000 bar·L are classified as A1, while those with a PV value between 200 and 3000 bar·L are classified as A2. . . . . The classification in Document No. xx issued by China’s State Council regarding special equipment is also based on the PV product; it is said that China is the pioneer in classifying pressure vessels

As a result, many small liquid chlorine containers, such as those with a capacity of 10 m3, will be classified as Category 2, and shall be designed, manufactured, and managed in accordance with the regulations for Category 2 containers.

The new capacity regulations have not been finalized or officially published; so how can we be sure that such changes will take place? For now, it’s sufficient to ensure that the 99th version of the regulations is properly implemented.

I just designed a container, and according to the new container regulations, it has to be classified from category two to category three

I have a PPT introducing the new capacity regulations; I don’t have it here right now, but I’ll send it to everyone later. I’m sorry

I have the draft of the new regulations; regarding the table in those regulations concerning the filling volume of removable media, it is recommended that it be modified in accordance with ADR. Because it is used for moving containers, it should comply with international practices. It is more appropriate to consider including standards, as more factors need to be taken into account, such as the medium, filling method, material, pressure, test pressure, etc., and it is also related to volume. The regulatory document can be found at the address http://tzsbaqjcj.aqsiq.gov.cn/zqyj/tzwj/200706/P020070615405142680485.doc. The ADR document is available at http://www.unece.org/trans/danger/publi/unrec/rev14/14files_c.html

The new version of the regulations seems to be called the \"Regulations for the Safe Inspection of Simple Pressure Vessels\", right? Your regulations are the \"Technical Specifications for the Safety of Special Equipment\" – that can’t be correct, can it?

There are changes in the requirements for pressure-bearing components made of aluminum and aluminum alloys (Regulation 99, Article 18). Aluminum and aluminum alloys used as pressure-bearing components in pressure vessels must meet the following requirements: 1. The design pressure shall not exceed 8 Mpa, and the design temperature range shall be from -269°C to 200°C. 2. When the design temperature is above 65°C, aluminum alloys with a magnesium content of 3% or more are generally not to be used. Article 18 of the (2008 Code for Pressure Vessels): When aluminum and aluminum alloys are used as pressure-bearing components in pressure vessels, they must meet the following requirements: (1) The design pressure shall not exceed 16 Mpa. (II) Aluminum alloys with a magnesium content of 3% or more (such as 5083, 5086) have a design temperature range of minus 269°C to 65°C. Other grades of aluminum and aluminum alloys have a design temperature range of minus 269°C to 200°C.

The risk-based inspection (RBI) technique has been added (ASME Code 2008, Article 131): Risk assessment (RBI) techniques can be applied to pressure vessels in use within large-scale plant systems. The procedures and requirements are as follows: (1) Users of large-scale complete sets of equipment that meet the following conditions may submit an application to the **supervisory authority to use risk-based inspection techniques: 1. Possess a sound management system and a high level of management competence ； 2. Establish and improve emergency response plans for various unexpected situations, and conduct regular drills ； 3. Equipment such as pressure vessels and pressure pipelines are in good working condition, and can be inspected and maintained in accordance with relevant regulations ； 4. The production facilities and key equipment are fully equipped with complete documentation ； 5. Stable process operation ； (II) Pressure vessel users who have obtained the approval of **supervisory authorities to apply risk assessment techniques may submit inspection requests to the risk assessment agencies approved by the **General Administration for Quality Supervision, Inspection and Quarantine, and shall simultaneously inform the registration authority in writing of this matter. 　　(III) The testing institutions responsible for the application of risk assessment techniques shall evaluate the risks associated with equipment and pressure vessels based on factors such as the condition of the equipment, failure modes, consequences of failures, and management practices; it is up to the user entity to determine the criteria for acceptable risk levels.

It’s just a draft; the final version hasn’t been released yet. We’ll wait until it’s available. It’s a bit early to discuss things now

I don’t know when it will be finalized and published.

As for when the new version of the standards will be released, agencies such as the General Administration of Quality Supervision, Inspection and Quarantine and the Standards Committee are very cautious, as these standards relate to various stages such as design, manufacturing, installation, use, inspection, repair, and modification; therefore, those provisions need to be carefully considered. Otherwise, if it’s introduced and then immediately revised, it would be strange not to feel ashamed. All are looking forward to the early introduction of new regulatory standards to streamline all aspects of quality inspection for pressure vessels!

Could you send it to me? My email address is jianguo.li@bayertechnology.com. Thank you!
