Problems with manholes

2009-04-12View Original

Thread Content

Have you ever seen a pipe with its outlet at a manhole? I wonder what the advantages and disadvantages are?

It would be best to send a picture of the scene so that everyone can have a more in-depth discussion

I seem to have seen such a connection before. The advantage is that one fewer pipe connection is needed on the equipment, but the disadvantage is that it is inconvenient for maintenance

The pipe outlet is located on the manhole; how are the pipe connected to the manhole cover, and how is sealing achieved between the manhole cover and the equipment? During maintenance, is it necessary to first remove the pipes and move them aside before taking off the manhole cover? I don’t think this is good. Who was the expert who designed it? Is it for some special purpose? It would be best to send a photo and provide some explanation so that we can learn from it*. This post was last edited by hgshy on 2009-4-12 21:56]

Having the pipe outlet on the manhole is not worth the drawbacks it brings! It’s not allowed when strict requirements aren’t met; one can only say that the designer sought to be innovative. We have never used such a design before.

It’s best not to do this, as mentioned on the 4th floor. When modifying a process, safety, ease of operation, and convenience for construction and maintenance must be taken into consideration first

Our company is a manufacturer of manholes, and we have been to many construction sites, but we have never seen manholes connected in this way. Yongcheng Pipe Rack Co., Ltd. of Sheyang County, Jiangsu Province (formerly Sheyang County Pipe Rack Factory): Phone number 13914610011; phone: 0515-82356556; fax: 0515-82356116. It produces rectangular insulated manholes, flue dust removal holes, circular insulated manholes, and other standard manholes.

During maintenance, a elbow with flanges can be considered to facilitate the removal of the manhole cover and pipes. Personally, I think it can still be installed on the manhole, after all, that reduces the number of pipe openings by one. :lol

:L is too strong. . . . It’s likely the designers will be cursed to death by future factory maintenance workers. . . . . . .

I’ve never seen it. What’s its purpose? Why is it necessary to do this? It only involves adding and removing flanges

If it’s a pipe connected to other components via soft connections, that’s also acceptable, but holes are generally not made in this way

The situation described by the poster is indeed very special; I’ve really never heard of such a design. I hope they can share the pictures so I can take a look:handshake

Haven’t seen it; I hope the original poster can meet everyone’s requirements. Send a picture to take a look. Everyone can take it as a reference and learn from it.
