RE: [MW:23850] Re: ASTM A36 plates for pressure vessels

By Materials & Welding

Hello Syed,

 

You should use A-36 steel for making fittings. Please see the materials requirements for A 234 fitting vs. the Scope for A-36 material. The text narrated below  is self explanatory. Any killed grade of C-Mn steel would be a good substitute for A-36 subject to the design requirements.

 

Thanks.

SA-234/SA-234M

 

Materials 5.1 The material for fittings shall consist of killed steel, forgings, bars, plates, seamless or fusion-welded tubular products with filler metal added and shall conform to the chemical requirements of Table 1. Unless otherwise specified for carbon steel plates, the steel may be made to either coarse grain or fine grain practice

 

SA-36/SA-36M:-

1. Scope

1.1 This specification covers carbon steel shapes, plates, and bars of structural quality for use in riveted, bolted, or welded construction of bridges and buildings, and for general structural purposes

dear Syed, 

 

strictly,code, there is no limitation on raw material for the products to be certified as per A 234, except it shall meets with chemical requirements of particular grade. 

If specific requirements based on service (like NACE), then restricted chemistry applies. 

 

regards,

SA-36 is permitted for use in construction of pressure vessels according to UCS-6 of the ASME BPVC. Practically nobody uses the same remains the fact.

 

No comments regarding the equivalency or use of A36 in place of A234.

Dear Syed,

 

Firstly A36 is just one common carbon structural steel,this steel plate can make common tanks,but not pressure vessels.Because,As a professional steel supplier,we knew when rolling A36,no need to do Ultrasonic test,but for pressure vessel used steel,they have to be done Ultrasonic test.

 

Second,your said A234 is one pressure vessel steel,actually another pressure vessel steel ASTM A285GrC is similar to A234.

 

It would be dangerous if using A36 to replace of A234,Freind.

Dear members,

Can a plate to ASTM A36 can be used to manufacture TEEs to A234 WPB, is there any restriction in BPV or B31.3 on the use of A36 plate for manufacturing A234 Tees.

One of client says A36 is for general purpose and cannot be used for making a pressure containing component to be used in oil and gas production . Is it correct, if yes why? And if not can you please provide me a technical justification, I could not find anything B31.3.

Thanks & Regards

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, ...
