Dear Fegenbush, in E7 table: 1-secondary containment is provided to control the product spill. 2-the roof and shell are designed to contain the sloshing liquid. could you please send a photo or sketch for containment stated in item 1 what is the exact meaning of the roof and shell are designed...

In bitumen storage tank seismic design (for SUG III) we have to consider a large freeboard. this area will increase the explosion risk of the tank. how can we fulfill the api code without increasing the freeboard.

Dear Fegenbush, Thank you for your early reply, the tank is for bitumen residue with density of 1.05 and design temperature is 210C. could you please explain the sump usages in process. regards.

For the API 650 Tanks, when the media density is higher than water, is that necessary to have a draw-off sump.?

Can anybody share some information about suction heater for diesel oil storage tanks, drawing and details such as power density, temperature control,... Thank you all in advance

I am involved in design of a BITUMEN storage tank complex. In API 650, we have only some strength consideration related to hot operating temperature. Where can find more details for hot service storage tanks, because for example stress due to expanding and contracting of the tank (during...

Dear Bimr, Thank you for your early reply, please find herewith enclosed the pump Curveshttp://files.engineering.com/getfile.aspx?folder=308d3916-4ed5-4bba-96c9-42c6744d6007&file=curve.pdf

I've recently integrated a new pump at a boiler feed water plant that is in addition to three existing pumps. Three old pumps are identical(2 motor driven and one steam turbine driven pumps) with 73m shut off head. The new pump (Steam turbine driven) is smaller and have 58m shut off head. When...

Thank you, all.

Dear Friends, We are looking for the procedure only, it means that the step by step actions, safety precautions,.. then we will hire an expert company to perform the hot tapping. Thank you

We are looking for a procedure for hot tapping a 4" branch on a 12" run pipe superheated steam 430C and 50Bar. The line is 25 years old. Cn anybody help me?

Hi, we have a steam line supplying steam for some steam turbines, we are going to take a new branch and supply 7000kg/h for a new installed steam turbine. how can I check if the size of main line is enough or not? the main line is 12inch pressure is 48 bar. the temperature is 430 deg C. how can...

Fluid is demineralized water. operating pressure is 3.5 bar operating temperature is 39 deg C Pipe sizes are 10,12,14 inch. Thank you

pipes are 10", 12" and 14". how about ebonite 65 deg shore D. we use soft gaskets 60 deg shore A. regards,

Thank you GrahamBennett, Maximum operating temperature of demin water is 39 deg C. We will use hard ruber lining with 4mm thickness. is that Ok? Thank you

Hi! Please let me know, the more common type of rubber suitable for boiler feedwater (demineralized water)? and how about thickness? thank you

Hi! Please let me know what is the recommended rubber type and thickness for rubber lining of demin water pipe (boiler feedwater). thank you

Hi!, I am not so familiar with Caesar II, But I have some questions: 1-after running the program how can we change the supports to reduce the nozzle loads. 2-when we assign the friction coefficient to +y restrictions, then the program will start nonlinear solution and it will take long time, is...

I am involved in designing a steam turbine piping system. the inlet flange is 4" and outlet is 8" as per NEMA SM-23 page 45: the allowable load for nozzle are: Fx=447 lb, Fy=1118 lb, Fz=894 lb, Mx=2236 lb-ft, My=1118 lb-ft, Mz=1118 lb-ft I used Caesar II to model the system, the forces are less...

I am going to design a steam driven pump piping. is that possible to install the safety valve after the gate valve in turbine exhaust? We have not enough area to install it before gate valve. Thank you!
