Thank you, cvg. Do you know how to qualify the CCTV/Sonar tape or where I can find this information?

For existing CSO pipe cleaning project, how much per foot include CCTV / Sonar inspection and cleaning. Pipe diameter is between 18" to 84". Thanks.

Does anybody know where I can find the CCTV & Sonar evaluation information?

1. Open acad.lin file. 2. Copy the existing file example and past it at the end of the page. 3. Modify it to what you want. Tip: The better to keep the standard default setting.

1. In model: Create drawing in 1:1 2. In layout: a) Create viewport and set up scale what you want b) in model space: use "z" c) in paper space: use "mvsetup" Note: pay attention about your dimension and text height. Good luck.

I think the point that you selected when you do stretch is the same as your dimension point. I mean you selected your dimension!!

CVG: Thank you very much about the technical resource. I'll use this in other projects, because it is combined sewer pipe this time. lha(Steve): Thanks for your response. I am insteresting this word because I know Chinese.

semo: Thank you. I can't use concrete junction box, because budget. lha(Steve): You are right. That's why I am thinking about Steel Coupling Reducing: www.smith-blair.com. By the way, why do you give a "Remember"? You know Chinese? cvg: Thanks a lot. I don't know if the reinforced concrete...

Connect new 36" Ductile Iron Pipe to existing 36" Reinforce Concrete Pipe. How can I do? Can I use Steel Couplings Reducing? Thanks.

No, I can't. Because: 1. There are enough capacity 2. Don't need change all of them 3. Too much more money

Thanks cvg[smile]. The pipe is working now. I can't drain the reservoir to replace the pipe[surprise][sad]. There is a gate valve in middle of the pipe. The gate shaft is on top of the dam. There is another valve nearby the outlet. We need repair the pipe that is between these two valves. I...

In this project, there is a 48" dia. 124 LF pipe(include pipe reducer from 48" to 36" for gate valve installation) which is under a dam about 100' and has 102 years. In the report:"...The overall condition of the pipe is fair due to heavy corrosion of the steel pipes and rivets with moderate...

Thanks for your reply Metalguy. The pipe is old smooth steel pipe and the dia. is 48". No saltwater.

What kind of coating system is better for the steel pipe interior painting? The pipe is under the DAM about 100 ft and the water resource is protected.[ponder] Thanks a lot for your help. [smile2]

cvg, thanks a lot to give me a good reminder.
