In what situations are loose-flange connections generally used? ? ?

This post was last edited by ylb913 on 2016-10-17 at 17:52. Flexible metal hoses, or pressure-resistant rubber hoses, are mainly used in temporary pipelines; one end of such hoses is fitted with a loose-flange connection, while the other end uses a fixed flange – that’s basically how they are designed.

Speaking of something unrelated to the topic, a few days ago the original poster asked a question, and I was fortunate enough to answer it; I think my answer was fairly good. I had intended to ask the original poster for feedback on my response, but they didn’t do so. . Well, if it’s not there, then there isn’t. Perhaps my answer wasn’t professional enough, but that’s understandable. After all, the purpose of answering questions on platforms like HaiChuan is to help one another; expecting the best answers might be too much. Today, while browsing the posts, I saw that the original poster had asked another question. Out of curiosity, I checked their profile and found that they had many topics, and in almost all cases, after someone answered their question, there was no further follow-up. There are hundreds of questions, yet none of them are marked as resolved. Isn’t that a bit problematic? OP, this is just my personal opinion; I’m offering you a small suggestion. If you don’t accept it, you can ignore it

Additional notes for the second floor: 1. For the flanges of precious metal pipes, ring loose-flange types can be made from different materials, thereby saving on costs； 2. (Similar to steel lining) The pipe fittings come equipped with flanges, and at least one end features a loose sleeve to facilitate alignment of the bolt holes during connection

On a positive note, it’s likely that the original poster is engaged in pipeline design or related work and doesn’t have time to reply； Speculating from a negative perspective, the original poster is posting messages, but it helps increase the number of posts on the forum. So, don’t forget your original purpose for coming to the forum: to help others solve their problems while improving yourself at the same time. Maybe the original poster didn’t reply, but other sailors saw it and learned something from it?

Cost-saving for corrosive pipelines, mainly used in corrosive environments and situations involving frequent disassembly and assembly to facilitate operations

All I’ve seen are metal hoses in the tank area

What does that mean? Do I have to choose the best answer after each question? I had no idea about this:P. I’ve never given the highest rating either; I just give extra points to others

The greatest advantage of loose-flange connections is the possibility of adjusting the screw holes when assembling pipes on-site, which reduces stress on the pipes.

I’m not just posting randomly; I’m raising these issues based on problems I encounter in my daily work. I don’t think it’s necessary to provide an absolute best answer – the moderator, please say a few words!

It wasn’t stated that one choice had to be made. When asking a question, if you select the ‘request for help’ option, then if you don’t choose ‘best answer’, the question will remain marked as unresolved; choosing ‘best answer’ will mark it as resolved. There was no requirement to do so or not. If you think someone’s answer meets your needs, then give it a ‘best answer’ rating – this is both a way of showing respect to the person who helped resolve your issue and also serves to indicate that the question has been resolved, making it easier for others to refer to it in the future. If you feel that no one can solve your problem, then you can refrain from giving a rating for now, until someone who can help appears. Different people have different opinions
