I have checked ASME NM standard but it says that mid point deflection shall be 13mm max. for the unsupported span. In my case that span is 4.8m and the deflection is well below 13mm. But question is the overall 70m pipe span on the pipe-bridge. what is the max. allowable mid point deflection for...

Thanks LittleInch, the vendor is Middle-East based and not a renowned one. So not getting enough support. I am looking for AWWA or ASME standard based guideline to calculate the max. allowable deflection. For underground pipe it is clearly given in the standards as 5% of the diameter. But my...

Hi, what would be the allowable deflection for FRP Pipe supported on pipe bridge above ground. Would appreciate your help in this. Thanks

Thank you @fel3 Thank you @HTURKAK great replies!

in addition to above: gasket material, bolts/nuts/washers material, tie rods material (here I am confused whether bolts nuts and tie rods are the same in this case?), coating type. what other things need to be included?

some things that I can think are: size, flange rating, flange facing, material. what other factors are important to mention in the specification for dismantling joints.

Thank you all for your great replies.

Engineering document titled "Data sheet for Orifice Plate" and "Specifications for Orifice Plate" would be same documents or two different documents? what would be the differences? Appreciate your time taken to reply. Thank you.

I have read about dismantling joints, posts on eng-tips as well. I am working on developing a document titled "specifications for dismantling joints" I need help what to be included, how much information is compulsory to be included. Anybody sharing such a specimen would be highly appreciated.

Dear All, It came out that velocity shall be much lower as mentioned by many people in this forum. It will be 3.5 m/s RTR pipe material will be used and pipe size will also be very large. Thanks everybody.

Thank you all for the technical info. The project is going to be one of the largest so there is big flow however mentioned velocity has to be checked. Process Engr. will be available after a week and i will update you guys about his response.

Hi, I am going to start piping for a project for which I found following details in process calculation sheet: seawater intake; pipe size 24"; velocity inside pipe is more than 25 meters per second. temperature is 30 Celsius. material is going to be super duplex or some other exotic expensive...

Dear All, I want to utilize an old FRP tank in stock for a current project. The previous nozzles would be closed if not at suitable elevations. But the problem is to add new nozzles. As per my knowledge new nozzle can only be added by FRP tank manufacturer or may be cannot be added at all. If...
