Re: [SOCIAL NETWORK] Re: [SOCIAL NETWORK] [MW:29874] vertical vessel piping _first rest support

Thank you hemant, I kept the support on pipe rack, deleted the support in vertical.

Yes I meant that the rest support on the pipe rack may be kept.

Dear Hemant,

 

   The horizontal spool length is just 2m and vertical = 3.8m. Hence deleted the support because we have immediate rest support on rack structure.

Do not know if your vertical support consisting of lugs is practically possible without incurring extra supporting costs.

The nozzle loads appear to be quite high.

Morever it is not clear how much is the overall pipe length in the horizontal direction for locating the rest support.  The vertical length of 3.8m has a dead load (empty) of 500 kg. overall considering even the horizontal length dead load . the load does not appear too much .

Hence the rest support looks okay unless it is located beyond the permissible span.

Dear all,

 

  Please find the below, sulfur absorber vessel, The following pipe mtl is A335 P11 and thk. = 14.27mm. The vertical portion is 3.8m only, immediately on the rack we have rest support

 

   If the vertical portion is long i.e if it about 15m and above, we have to provide rest support either rigid or spring in vertical portion.

 

As per below snap small vertical vessel and the pipe size 12" sch 60 we have more span. Providing support and if not in the vertical portion doesnt impacting the nozzle loads. The nozzle loads are Fx=Fy=Fz=18Tons and Mx=15tons, My=Mz=7tons. In my point of view first rest support is not required in this case, kinldy share your opinions

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

Introduction The colour formed when stainless steel is heated, either in a furnace application or in the heat affected zone of welds, is dependent on several factors that are related to the oxidation resistance of the steel. The heat tint or temper colour formed is caused by the progressive thickening of the surface oxide layer and so, as temperature is increased, the colours change.   Oxidation resistance of stainless steels However, there are several factors that affect the degree of colour change and so there is no a single table of colour and temperature that represents all cases. The colours formed can only be used as an indication of the temperature to which the steel has been heated. Factors affecting the heat tint colours formed Steel composition The chromium content is the most important single factor affecting oxidation resistance. The higher the chromium, the more heat resistant the steel and so the development of the heat tint colou...

Re: [MW:10788] ON PLOT PIPING & OFF PLOT PIPING

Piping systems involved for the flow lines and gathering lines from the well head isolation valve to the production facility or processing plant isolation valve are determined as OFF PLOT. ON PLOT defines piping system in the processing plant and production platform. ANSI/ASME B31.4 applies for off plot piping system. B31.4 allows the use of either API 1104 or ASME section IX (as appropriate). However, occasionally, a very small system such as piping within 500 feet of a processing plant (some client also said 400 feet) may be declared B31.3 rather than B31.4. When B31.3 is invoked, only ASME Section IX is used. before you decide which code to use for welding procedure and/or welder qualification for pipe welding, you have to know the design and construction code applicable to the system. Please read far enough into scope and diagram illustrating the application of either B31.3 and B31.4 hope this helps rgds 2011/4/21 pradip kumar sil < pradipsil@gmail.com > Dear all, ...
