I'm working in a water supply project with high pressure concrete pipes (up to 350kPA). Initially we thought about weldet joints but theres a fabricant who proposed a rubber gasket joint. The problem is that i think that this kind of joint is not recommendable for pressures above 190 or 200kPA...
Do you have some advantages/disatvantages for steel pipe coatings? Any suggestion which to use (economical and tecnical reasons)?
For example:
AWWA C203 Coal-Tar Protective Coatings and Linings for Steel Water Pipelines
AWWA C210 Liquid-Epoxy Coating Systems for the Interior and Exterior of...
Comparing the following standards:
-AWWA C200
-API 5L
-EN 10224
my conclusion is, that AWWA C200 (and EN 10224) is just applicable for steels up to grade 55, when API 5L is also applicable for X60 - X80 and in my case I need up to PN70, X65 --> API 5L
Please respond if you disagree...
I am working in this part of the project since a few days and as far as i can see at the moment the mechanical calculation is based on AWWA M11 "Steel Pipe- A Guide for Design and Installation" and API 5L standard for pipes and welding qualities.
Indeed I was surprised and so I began my...
The problem is that normally i am working with the european standard (EN 10224) and i don't have the API yet. The pipes we have projected are for water for human consumption (up to PN 70, 1219mm) and we need a standard to applicate in the technical contract conditions in Mexico.
The case is...
