Answer from Werner Sölken

Hi Ben,
I can not tell you why suddenly there are minor differences between your gaskets and flanges.
In recent years, many flange standards changed, but in principle the dimensions of the flanges are not.
Ask your supplier of flanges, maybe he can give an answer.

Make a simple check:
In the main Menu "DIN" you will find the dimensions of DIN flanges, make sure you dimensions of flanges and gaskets common with it.

Answer from Werner Sölken

Hi Vyanu Vyas,
I am not a manufacturer or supplier of piping materials.

A split tee of this size is probably not a stock item and must be manufactured by a recognized company. Below some manufacturers / suppliers:

Question 97: raised faced spectacles, blanks and spacers

Hi,
Please clarify the Raised faced spectacles, blanks and spacers

Regards
Ramana Babu / India

Answer from Werner Sölken

Hi Ramana Babu,

ASME B16.48 says: A raised face may be specified at the option of the purchaser.

This would add machining time and complexity so the price would be higher. Call this the Bugatti or Rolls Royce of the line blind world.

Personally, I have seen that version once or twice somewhere. The version without Raised Face is the default and is used everywhere.

Look at Spectacle Blinds and/or Spades at the bottom of each page.

Hi Mike,

1. TEE EQ 2½-40S-B16.9-A403 WP316L-SMLS

I like your site. This is full of great info, and, you are correct, there is no precise place to go for this info.
Very nice, good luck. One thing, perhaps you might put a home page in. It is most common and people will go there first for bearings as to where to go from there.

Question 91: is there a world standard on support symbols that we can use

Hi,
We are working on a project at Sasol Secunda. We stumbled upon a issue with the support symbols. Is there a world standard on support symbols that we can use, or must we create our own symbols.
Will appreciate it if you can send me some info in this regard.

Thanx

Your question has been asked me many times, and soon, I'll write an article with useful examples. At the moment, unfortunately I can not help.
