** ISO Tube according to EN10217-7 does NOT specify any pressure values, also because so many factors can effect working pressure. 
** We cannot guarantee the pressure values listed as they are for general information and to be used as a guide only.
** There is formula to get the working pressure of T304/L welded tubes at room temperature (this formula is merely indicative and do not involve so many variables):
** Formula used:- 10.2 x 200 x thickness            
--------------------------------- = bars          
Out.Diam – thickness            
** IMPORTANT:The working pressure values indicated are as a GUIDE only, and Neumo UK Ltd accept no liability to any loss or damage caused by using this information.
