HG/T21594~21604-2014 Standards for Stainless Steel Manholes and Handholes
Thread Content
I’ve been searching for a long time without success; I can’t find HG/T21595 and 21601-2014. I wonder if anyone here has these two standards – I’d appreciate it if you could share them with me
The versions of HG/T21514~21535-2014 that were found previously

Some additional insights regarding manholes: Taken from HaiChuan. 1. Model HG21594 features stainless-steel manholes for normal pressure applications, while model HG21514 uses only carbon steel for such manholes. 2. In HG21594, the flanges of the stainless-steel manholes (except those for normal pressure applications, which have entirely stainless-steel flanges) are made of carbon steel lined with stainless steel; whereas all flanges in HG21514 are made of stainless steel. 3. The pressure ratings for HG21594 manholes include normal pressure, 0.6, 1.0, 1.6, 2.5, and 4.0 – a total of six levels. The pressure ratings for HG21514 manholes include normal pressure, 0.25, 0.6, 1.0, 1.6, 2.5, 4.0, and 6.3 – eight levels in total. HG21514 is simpler to manufacture than HG21594, has a wider range of applications, and is more cost-effective. The stainless-steel manholes in the HG/T21514–21535 series are entirely made of stainless steel (with the exception of some structural components), while the flanges and cover plates of the stainless-steel manholes in the HG/T21595–21604 series have lining plates. It’s mainly this difference.
The absence doesn’t mean it might be replaced; it just means that file hasn’t been found. But I hope it can provide you with a starting point. Let’s take a look at two images below: 1. It is not mentioned in the new version of the catalog either; 2. These are references to the explanations regarding what has been replaced and merged in the pipe flange standard HG20592.
Standard HG/T21595 should be abolished; the standard HG/T21515-2014 includes manholes made of stainless steel
Thank you for sharing; I’ve been looking for stainless steel manholes for a long time
Thank you to the person who shared the collection below; I was able to download it all at once.
