non pressure plate flange

Date 02-17-2009 22:13

Hopeing you guys can help me out here. I need to make some manways out of 30" pipe for access to storae tanks. The tanks are non pressure. Any suggestion where i can get a plate/ring flange about 1/4" thick and blank flange for the lid. I need to make 60 of these manways and to have a local shop laser them is outrageous. Hopeing someone can steer me towards a company that produces these things instead of haveing to get them custom. Any help is greatly appreciated.

Call a big supplier who has a burning table if you need 60 of them shipping should be pretty reasonable.

manufacture them yourself, if you describe the application and which way they will be positioned and whether they need gaskets or any other particulars , could help as our company has built many many different style of tank lid covers

I'm going to ask a question.
You're speaking of "manways for non pressure storage tanks". Of course, "non pressure" means that the tanks will be subjected to atmospheric pressure. What kind of fluid will the tanks contain? Oil and/or oil products? Then the tanks should be designed and built to API 650, and the manway dimensions are clearly stated on it. For sure, the blind flange that covers the manway is thicker than 1/4 inches.
Or will the tanks contain water or other non flammable liquid? In this case, the tanks should be designed and built to AWWA D100, that also states clearly the dimensions of the manways. Again, for sure, the 36 inches blind flanges that cover the manways are thicker that 14 inches.
Or will the tanks be designed and built to some other standard?
