Problem with Pipe Connection?

Please see this picture and tell me if there are no problem with all connection. You know, working pressure is 60 bar and I afraid that it may leak or broken.

What is the lowest rating of any individual component at process temperatures?

What is the reaction force from the nozzle? Is the line correctly supported?

The piping arrangement as shown is acceptable for a CO2 fire suppression system subject to the following:

1. All fittings must be 300 lb. class WSP or 1000 lb. forged steel.

2. All reducers must be concentric.

3. No reducing bushings allowed.

4. All pipe must be schedule 80 minimum.

5. The ball valve must be approved for a CO2 system.

All your fittings are 3000# (3000 psi) = 206.8 bar against your requirement of only 60.0 bar.

This drawing seems in-complete. Pipes upto 1inch size should be of Sch. 80, You have not shown details of 90 degree bends of 1/2 inch pipe, butt-weld fitting shall be of same schedule as pipe. Valve rating is not specified. It should be of 1500 class or so. Threaded fittings class also shall be specified. As the lengths of pipes are not specified, need of support is not considered.

Yes, right!

Pipe sch is XS/S80.

Valve class is 1500# .

Fitting 3000# (both Socket welded end & Thread).

Don't use pipe bend, use 3000# socket weld end Elbow.

Support will be considered after completely installation of Pipe & piing component.

Regards
