For sure it is hazardous. I do not know if it polymerises. I do know that a lot of heat is generated, then the system get over-pressurized, and the pipe or equipment has a great chance of rupture.
What are the conditions that determine an uncontrolled ethylene decomposition in a vessel, pipeline or a well?
From what I know, decomposition can occur:
1) at certain rates of compression
2) at high temperature
3) when there is water, air, rust, or other foreign matters in ethylene flow path...
Anybody has a formula that calculates the minimum wall thickness of a pipe when subjected to external pressure?
ASME Section VIII that I have is missing Appendix. 5.
Thanks
Anybody knows what clearances should be between impeller wear ring and bowl wear ring in a vertical can pump?
I know that API 610 gives clearance data, but are they applicable also to can pumps?
Shut-off valve is a valve that can be closed quickly if an emergency situation occurs in you facility. The valve has an actuator that operates on air, UPS, hydraulic fluid, etc.
Cv of a 24" Grove B ball valve:
310 at 15 deg. open;
560 at 20 deg open;
1390 at 30 deg open;
2600 at 40 deg open
4500 at 50 deg open
7800 at 60 deg open
13150 at 70 deg open
27000 at 800 deg open
98600 fully open.
You need to calculate the Cv for your conditions and determine at what...
I need to determine visually if a tubing installed on a metering skid is 304 SS or 316.
I understood that you can differenciate between SS 304 and 316 (or 316L) by looking at the tubing. 316 looks shinier.
Do you have to spray the tubing with water to start some surface corrosion?
Anybody...
