I have a carbon steel pipe component (B31.3) that I need to PWHT because of a sour service requirement. All of our past projects have not had the PWHT requirement.
This component has a critical interior surface finish, so I need to limit corrosion as much as I can, such that any rust that had...
The unit I'm designing requires a minimum number of welds and therefore there is a strong preference for double random (40 ft - 12m) nominal piping.
I'm talking pipe sizes 1"-4" - some in schedules other than STD or XS.
My projects can be fabbed in the US, Korea or Europe.
Over the past...
I'm using cal sil insulation on a refinery project. The client's insulation table and a couple vendor websites have indicated that 25mm (1") thick cal sil is available, but some of my colleagues are questioning whether it'd be too fragile. They were concerned it may be tough to work with and...
I have an externally generated requirement to provide belleville (spring loaded) washers in my piping system. I haven't used them in the past, but passed along the requirement to my subvendors. (B31.3 piping - hydrogen service)
I have a supplier who's objecting to providing them on the grounds...
I have a 650 hp motor on a vertical pump. The thrust bearing is located in the motor housing. The proposed thrust bearing is rated for 50,000 hrs - so I'd need to count on changing it out once every 5 years or so.
Can anyone provide some budgetary cost data on a bearing replacement of a motor...
I have an underground double wall fuel oil line (pressurized). Our normal practice is to use interstitial leak detection system to detect leaks, but we're getting a little resistance.
The EPA regulations I've seen in my research to date have been concerned primarily with underground tanks (and...
I have an interesting problem.
I have a tank with oxidation air injected at the bottom. I need to make a rough estimate of the change in the level of the tank when the blower trips offline.
I know the flow rate of air entering the tank, but I do not have how much time that an average air...
I have a project (Flue gas desulfurization) where we'll have slurry pumps and lines as part of the process. We're planning to have a trench system draining to a sump to collect line flushes, drain flows, etc.
The slurries will be a 30 wt% limestone, 20 wt% (mostly) gypsum, and we'll have some...
I'm looking for an opinion regarding tanks used in a flue gas desulfurization project.
I don't know which code to specify - API 650 or AWWA D100.
The fluid will be a 30% limestone slurry. It's water based, but can also be considered process. The fluids are not hazardous, but should not be...
