Below you will find everything about pipe dimensions in the steel industry.
Did you know that all types tube dimensions can also be ordered in our webshop!
Pipes are also called differently in common parlance. In practice we encounter descriptions such as:
From the above you will understand that a lot of confusion can arise because there are many different pipe sizes, terms, descriptions and standards in circulation.
We therefore recommend that when making a request or placing an order, you only discuss the external tube size (pipe size), wall thickness and descriptions such as quality, finish, etc.
UD = external diameter of the pipe.

Dutch Dairy standard
Previously according to regulations DIN 11850 Food / Dairy / Beverages - Internal average roughness value Ra ≤ 0,8 µm and ≤ 1,6 µm in the welding environment.
New standard in 2014 - EN 10357 Series D Food / Dairy / Beverages - Internal average roughness value Ra ≤ 0,8 µm and ≤ 1,6 µm in the welding environment.
Hollimex also supplies these pipes according to the EHEDG guideline with an internal roughness value Ra ≤ 0,8 µm also in the welding environment.
DIN 11866 Reihe A, H3 Pharma application - Internal average roughness value Ra ≤ 0,8 µm and ≤ 0,8 µm in the welding environment.
DIN 11866 Reihe A, H4 Pharma application - Internal average roughness value Ra ≤ 0,4 µm and ≤ 0,4 µm in the welding environment.
Hollimex supplies more and more products that meet the EHEDG guidelines meet. Think of dairy pipes, appendages and process components with an average internal surface roughness Ra ≤ 0,8 µm (also in the welding environment). We often supply these products under the name QH-Plus . So very recognizable for you.
