Concentric reducers are two concentric circles for inlet and outlet, they do not have a flat side. So when using concentric reducers, there is always a liquid pocket when flowing from large to small side. Eccentric reducers have an offset from inlet to outlet so that there is a flat side. If...
Shoes are a normal solution for this, especially if your pipe is insulated. Similarly, you can just rest the pipe on a non-metallic pad. There are even some load rated products for this like I-rods which you can buy by NPS, height, etc.
I second having multiple dip tubes. Having some manner of variable component would add complexity and error to a process that could essentially just be a hot swap.
The other limiting factor on the low temp available in your flue gas is the dew point. Flue gas often contains some nasties that you don't want condensing out and corroding your equipment. So if you have the composition of your flue gas, you need to figure out its dew point and remain a margin...
As long as both are okay for pressure and service, I would go with RPTFE. PEEK is great at high pressure, but can be a bear to turn (really stiff seat).
Not my area of expertise, but I would think it would have to do with flame direction, flame length/velocity, and general shape of the furnace as LittleInch noted.
Confirming the above on a design pressure at a minimum of 290. Design pressure, and its coincident design temperature, are the physical scenarios the pipe will experience that result in the greatest wall thickness/rating. Burst pressure is not a factor.
My thought is generally yes it can be. It is quite common for the field work to be done by techs, designers, or other surveyors for projects of varying size. As long as the proper field work is done (usually at the request of the EOR to get x, y, z datapoints especially) and the raw data is...
Yes - that is actually the only use case I have ever used stainless in steam piping before. Humidification system for a high purity aerospace application.
Steam piping material selection is temperature dependent. In almost all cases, carbon steels are fine. If you are getting really hot (650F+, depending on the steel), then you might either need to evaluate for creep and/or switch to a chrome moly.
SS is also fine in most normal cases but I...
So without doing any math, I would make a few changes.
First, I would opt for a trapeze off the bottom of the W beams. That way you go direct into your moment connection on the flange of the W beam without a torsion bar in the middle.
Second, I would opt for limit stops, u-bolts with limit...
Relatively hard to determine without pictures of the layout, but why would sucking air be a diagnosis if this only happens during blowdown? I wouldn't think your blowdown would affect the BFW tank level beyond just standard pump rate.
I've worked at a couple EPCs (where licensure would matter) and getting your license was a semi-barrier in going from a 2 to a 3. I say semi-barrier because there are exceptions, especially for outside hires.
At one firm, it went something like Associate Technical Professional -> Technical...
