HI there, now i am facing a problem about the pressure drop in ball valve. our company produce a kind of ceramic ball valve against high corrsion and high temp, which was inquried by a mid-east petrochemcial company. the engineer ask for the pressure drop of our reduced ball valve. the ball...

the technical specification in brief below: Ball Valves, flanged ends raised face, threaded seat ring, controlled hardness, Body A216 WCB, regular port, ball SS 304. Now I am very curious about the threaded seat ring used in big size(2"~16") ball valve manufacturing? because I rarely find this...

1. thanks for you info, our company so far aims to process 24" ceramic product, for instance, ceramic tube or ceramic ring. so the processing range is from 1/2" to 24", anticipate someone could provide some useful manufacturer info about this kind linear cutting manchine. thanks a lot! 2. In the...

Hi, our company is planning to purchase a professional linear cutting machine for precisely processing the structural ceramic products according to our engineer's drawing. Hence, anybody can help to provide some useful info or recommend some manufacturer of this sort of linear cutting machine...

At the same time, is there anybody can provide some material to introduce this coal to oil technology? which country now plays the main role in this field? I heard from the internet that this technology is quite new, few country can handle this application. Thanks!

As I know, one of Chinene province is cooperating with SASOL for setting up a joint venture to pursue the Coal to Oil programme, but the inventment budget is incredibe high! Normally, the investment on the coal to oil pragramme is 6~9 times of conventional refinery investment equivalently. So...

Thanks so much for you guys kind reply. i just found out that the pressure differential between the upstream and downstream as follows: Pressure for the control valves installed: 1) At condensate discharge line from compressor plant dust collectors and from condensate collector of pig...

Is there anybody acquainted with the calculation of valve flow rate, the parameters at hand as follows: 1.Nominal diameters of control valve DN 50, DN 80, DN 100 Working media: gas condensate with water, methanol and 2. mechanical impurities of size up to 100 microns 3. Density, kg/m3...

To:mighoser the website you recommended is very helpful. My thanks

I just wanna search the common 316 SS mechanical properties in the internet, but i failed to get the ideal result. So I turn up here for the help with respect to the following items: 1.Compressive Strength 2.Fracture Toughness 3.Impact Toughness 4.Flexural Strength or more information will be...

To: AEH3, your information is so important to me, it's really helpful. thank you so much! Thanks all you guys for your replies.

To Mr. Greg Johnson, Thanks so much for your reply and your article. Your article is so significant to the guy as his reference. Appreicate it again!

Our company just did a very simple experiment about the thermal shock resistance of ceramic ball. the procedure like: ceramic ball with Temp.15 C, put it into a furnace with Temp. 200C, then increase the temp. to 250C with 25 minutes, open and pick out the ceramic ball after keeping temp. 250C...

I just got a requirement from my end-user about providing the ceramic test report in terms of 1.Thermal Shock Resistance (50F~500F) 2.Compressive Strength 3.Fracture Toughness 4.Impact Toughness 5.Flexural Strength Now i am facing the issue about the Thermal shock resistance test method. Is...

I just need an english version paper about the introduction of GATE VALVE, better it's a academic one. actually this is special for a guy of my colleague's younger brother as reference. Anticipate and appreciate anyone could help. Thanks in advance.
