It’s an easy job for inspector to just reject it. 🙂

The superheated steam is typically dry without too much condensate. But, the function of the steam trap may be needed to be covered from the cold system startup which may generate a high condensate flow. You may confirm it with the Process Engineer and Operation for the startup process.

Op, Need to clarify with where it’s from.

Refer to the TLV manual link below for the steam trap operation https://www.tlv.com/en-us/products/steam-traps/mechanical/high-pressure#2 Basically, the correct selection of the steam trap is based on the how much DP and the required condensate capacity. See the picture animation for the float...

One possible option is to search the “National Board #” on the pressure vessel name plate, and contact the NB Resigtration for any existed info regarding this vessel. It may need some time and effort for it but worked in the past. Good luck.

1. With no flow, the heat is to conduct inside the pipe through the air slowly along the pipe to reach the temperature as specified. 2. To use multiple steam tracers along the 40” pipe or wrap it around to have the constant surface temperature around. 3. Consider a temperature monitor with the...

It looks that this is just a preliminary piping sketch to show the support nodes along the piping routing. The next step is to have a Piping Engineer to review the piping loop routing design and perform the stress calc for the required anchor or guide at the proper locations.

IMO, it looks that someone is playing the “Lego” blocks of four pumps and pipes without any design. To make a real system, here are some additional questions for the thought: - adequate pump spacing for safety operation and maintenance - proper mechanical anchors for pumps - proper electrical...

No, it’s incorrect.

Another option of the steel caisson is to use the sheet piling to have the safe egress and adequate work space for the deep underground work.

The project should verify the total demanded water flow for the plant and confirm with local AHJ and per the fire protection codes. If the sprinkler system is only intended for the equipment cooling in the fire incident, it may be turned off and save the water through the hydrants as required...

Not like the pressure vessel may required to be certified per ASME BPV Code, if there is nothing wrong with the 15 years old piping, such as corrosion, the Engineer may determine once the pipe material is suitable and new process conditions, P&T don’t exceed the original design parameters.

IMO, the spillback of the injection pump is typically routed back to the tank without any concern. The return line of the 25ft head shouldn’t be the issue for the pump discharge.

To contact the steam blow service contractor who is specialty in cleaning the steam pipe as needed such as turbine piping. He will review your steam piping layout, and provide you the proper piping route for testing, the required orifice size for the proper steam flow rate, temporary connecting...

It’s responsibility of the piping designer to receive the actual design condition of the “ASME BPVC pipe” from the responsible Vessel Engineer to ensure that the connecting B31.1 piping are properly specified. Don’t assume anything if something is not clear or lack of information.

Questions to OP, What is the reason to replace the existing welded control valve? What is the maintenance history of the existing welded valve? Are the U/S and D/S block valves welded or flanged valves?

IMO, it’s a good workmanship to have a smooth weld seam without any ripple, groove, extra metal, etc., as requested by the common Code and standards.

It’s normally no issue to mate the RF flange to FF flange of the CS and SS material, but not cast iron. As the request of the FF flange connection, the question is what are the details of the “flat plate flange” on the connecting components, such as material, part detail, etc. For sure to...

It won't work to have several steam lines to use one common steam trap for recycling the condensate. Normally, the steam trap piping should be used for at each condensate collection points, which connected to a condensate collection header. The condensate header size should be adequate for a...

The half coupling fitting on the branch connection is similar to the sockolet fitting which is integrally reinforced for good branch connection strength. Even the only pipe branch connection without the reinforced pad is accepted by the Code, the Company has replaced this connection in the plant...
