[MW:1749] Re: 1747] Re: Use of 316L for steam service

By Materials & Welding
I understand that the core material is SS316L and what is the jacket
material?
What is core fluid and what is jacket fluid?
What is ambient environment? Any leakage or any other gaseous hazard?
I told you for additional info.
Please appreciate that I need to have the total picture.

I think no problem. You can go ahead.
Your argument may be correct if there is Cl2 or Fl2 environment.
If core fluid is compatible to SS316L, are you bothering for steam?

Regards,

Bibek Bhattacharyya.

Dear sir,

There was a recommendation that a 316L material be use for inner piping
of jacket piping. I am trying to put up an argument that there could be
some problem in the usage of this material. The service temperature is
233F and the steam is 338F, the pressure are 15 and 75 respectively.

Thanks and regards.

Please indicate the steam pressure and temperature... Also, the
frequency
of use... At a glance, the material can be used but for further
analysis,
more info is needed.
B36.19M and B36.10M.
For large bore SS pipes, you can specify thickness from 36.10M, based on
your requirement.
You can refer or use "ASME B31.3 Calculator" at
www.cheresources.com/software.shtml.

Dear All,

Can anybody please tell me if 316L for steam service is tolerable or
not.
Is there any reference in B36.19M with regards to this criterion or in
any
industry codes.

Thanking you all in advance.

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

By Materials & Welding
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

By Materials & Welding
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, ...
