Yes what u have taken is correct one. St/Sd is generally one
As Hydrotest is generally room temperature only but chk this with ur boss may be he is suggesting you for difference in test temperature and design temperature.

Hi
For branching as far as I know ther are following are the options
1) Equal Ts
2) reducing Ts
3) Stub ins ( With or Without reinforcement pads)
4) Half coupling
5) -- lets and ts for U/G services having 45Deg branches
ETC ETC
But which to use when is there any criteria? I know for a...
Is there any thumb rule available for knowing the thermal expansion or contraction (directly propprtional to length and delta T) of routed cs, ss pipes because in 31.3 tables are for mm/100 ft and that also as per temperatures.

In a nut shell it is required for following purposes
1) With valve for double chk of isolation while doing maintenance
2) To cover up the mallfunction of the valve if any
3) To have mental satisfaction that even if by mistake some one opens the valve then the area should not get fluded.
4) Its a...
Ok cost business is one thing but it is used in hydrocarbon service also which is most dangerous thing so why not to stop at valve only (e.g. aircoolers isolations)

Hi
I heard that Inch Dia is the term used for welding of pipes.
and Inch Meter is the term used in construction purpose
Can any body explain those terms.

Is there any thumb rule, guide line, notings available for calculating the pipe loads on secondary pipe supports (like cantilever brackets, inverted L suppoets, Inverted goal post supports) so that it is sure that the members used for such a supports are safe for such loads (because in the load...
What is the exact use of Spectacle Blind?
Some times it is used with valves as spectcle blind gives same effect as that of isolation valves then why Spectacle blind is used? If the Spectacle blind is to be closed from open condition is there any spilage of the fluid ( in absence of Valve)?
Sachin
Can we use same support spacing in vertical pipes as that of horizontal pipes? General guide line for horizantal lines is 2 rest suppots and a guide (on rack)so is there any guide line there for vertical spacing? Any thumb rule for vertical pipes supported from vertical vessel? as in vertical...
Thanks a lot, ok it is concluded that cs shoes can't be directly welded to SS pipe but is it because of metallurgical reasons (chemical comp. of mats.) or differential thermal expansion coefficients or difficulty in welding process?
Sachin
Hi
I a want to know that can we use same pipe shu material (Shu i.e. inverted T welded to pipe directly) for hot insulated carbon stell pipe and stainless stell pipe? Any criteria behind it?
