We hope everyone will actively participate and point out any shortcomings; we encourage everyone to come up with good ideas. We will respond to everyone as quickly as possible and do our best to meet their needs. We will make effective improvements to this section based on the feedback received. Unless otherwise specified, the top post in this section will remain in place for one to two weeks before being replaced with new content. Benefit more people. Rather than clinging to outdated methods, it’s better to give up completely. No one wants to do that, as they don’t want to stop halfway. Boost a few popular posts a bit; back and forth to liven up the atmosphere ； Improve requests for help in recent posts, and earnestly address urgent needs. Management content: 1. Deliver the 【Daily Question】 and 【non-help-seeking discussion topics】 a few days in advance. 2. Highlight the [Help Discussion Type Topic] for one to two days on that day. 3. Raise the relatively new 【Help Discussion Topic Type】 in order to obtain conclusions and assistance promptly. 4. Remove meaningless content from [Help Discussion Type Topics], by deleting it or merging it and then deleting. 5. Delete the previously hidden posts. 6. Edit the settings for posts without a theme category. I believe that with everyone’s joint participation, our layout – like bamboo after the rain – will be unique and innovative, bringing benefits to all and offering a pleasant visual experience. 1. Some people have suggested that the [Daily Question] often takes up too much space. We will address this issue by splitting it into two parts: First, the 【Daily Question】 posts that are submitted more than one or two days in advance, as well as comments on topics that are not related to discussions or requests for help, will be handled promptly, so as not to interfere with everyone’s communication. Second, the comments on the 【Daily Question】 from the past two days, along with other discussion posts. Additionally, for all topics beyond a week old, if the final reply is meaningless, they are also downgraded. .............................................................................................................................................. 2. Some people have suggested that the topic collection feature for 【Top of this version】 takes up space with little value. The temporary solution for this issue is: first, stop accepting submissions for the topic. Second, replace the pinned hot topics with new ones in a timely manner. Third, the topics that have been set as pinned, along with those that were previously pinned, are listed below in chronological order: Starting date: February 21, 2019. 1.1 Topic collection post for the “Daily Question” section in the Tower and Unit Equipment category (prizes for participation): https://bbs.hcbbs.com/thread-1317213-1-1.html 1.2 Topic collection post for the “Weekly Topic” section in the Tower and Unit Equipment category (prizes for participation; valid indefinitely; spam is strictly prohibited): https://bbs.hcbbs.com/thread-1247477-1-1.html 1.3 Topic collection post for the “Daily Question” section in the Static Equipment category – “Wealth + Charm = Rewards”: https://bbs.hcbbs.com/thread-2268291-1-1.html 1.4 Integration of the first round of discussion posts – followed by a summary: https://bbs.hcbbs.com/thread-2275557-1-1.html 1.5 Integration of the first round of mini-event-related posts – followed by a summary: https://bbs.hcbbs.com/thread-2275595-1-1.html 1.6 Problems encountered in the stress analysis of large-diameter high-temperature heat exchangers: https://bbs.hcbbs.com/thread-1907412-1-1.html 1.7 Selection of welding joint coefficients for pressure vessel heads: https://bbs.hcbbs.com/thread-2300223-1-1.html 1.8 Questions regarding the evaluation of welding processes for heat exchange tubes and tube sheets: https://bbs.hcbbs.com/thread-2295317-1-1.html 1.9 Question: Welding of 0Cr25Ni20 stainless steel – what precautions should be taken when welding this type of stainless steel? https://bbs.hcbbs.com/thread-2309570-1-1.html 2.0 Seeking help regarding welding materials for 304 and 316L – is a welding procedure qualification required? https://bbs.hcbbs.com/thread-2317615-1-1.html 2.1 What should be the thickness of the shaft lugs on manhole covers and flanges? https://bbs.hcbbs.com/thread-2297863-1-1.html 2.2 Questions related to the list of entities authorized to produce special equipment https://bbs.hcbbs.com/thread-2318408-1-1.html 2.3 Is it necessary to obtain the opinion of the original design team when installing an operating platform on an existing pressure vessel? https://bbs.hcbbs.com/thread-2320132-1-1.html 2.4 Marking of composite board thickness https://bbs.hcbbs.com/thread-1778315-1-1.html 2.5 Problems with composite boards? https://bbs.hcbbs.com/thread-2326691-1-1.html How to provide support for containers with repairs at 2.6; seeking advice. https://bbs.hcbbs.com/thread-2347366-1-1.html Classification of multi-chamber pressure vessels at 2.7. https://bbs.hcbbs.com/thread-2343817-1-1.html What technical requirements need to be considered when designing containers whose operating medium is only blast furnace gas?
