Hi, The pipe specification is asking for a spiral wound gasket but the flow meter has a PTFE lining. The spiral gasket has already damaged the face of the lining. Could you please give me an idea that if only replacing the gasket with a non-metallic one is sufficient.
Another question that I...
Hi,
In many specifications of refineries (Oil&Gas), the minimum body size of Control Valves specified as 1 in and 300# class regardless of Pipe size and specification. Could anyone give me an explanation.
I am trying to replace a 1/2" pressure regulator with a control valve therefore I am...
Hi,
For controlling condensate level in a LP steam condensate flash drum we are using a globe valve 1-1/2" in a 4" pipe. Calculation shows that flashing occures inside the valve. Any suggestion for retrofitting the existing trim and or changing the piping layout. Process conditions are P1=40.6...

Hi,
For preparing catalyst we are using a 7' ID by 9' T/T Carbon Steel mixing tank with agitator at around 30 % height of the vesssel from the bottom. Vessel is vertical. We are going to install temperature element to measure and control the fluid (mixed) temperature at 25 (±5) deg C. A 4"...
Hi,
Could anybody brief me about why we normally put Orifice plate upstream of the associated flow control valve in the flow loops. Is this because of upstream requirement of the orifice plate?

1- How can I estimation a ball valve full stroking time with spring return piston actuator. Any formula or guide line.
The valve is in ON/OFF application for depressurizing a reactor.
2- Does it stroking time differ if two actuator relieve through the same solenoid?
