[MW:25803] For Cryogenic Services at Temp -196 degree Celsius (17 Kelvin) Pipe of ASTM 312 TP 304 L is suitable?

By Materials & Welding

Hello Vivek,

 

Your query is on the best compatible materials for :-Liquid Hydrogen, Liquid Oxygen, Liquid Helium, Liquid Nitrogen, Gaseous Hydrogen, Gaseous Oxygen, Gaseous Nitrogen, Gaseous Helium environments. The design temperatures for all of these gases in liquefied stages vary from -160 deg C to -196 deg C.

 

Amongst the 3 grades mentioned below, 304L and 316L would easily meet the cryogenic requirements down up to -196 Deg C. SS 321 could be a subjective choice below -160 Deg C.

 

The requirements are for “Cryogenic Engine Testing Facility” which is not child’s play, hence one has to understand and follow the guidelines of ISRO.After all they the designers and owners of these systems.

 

Discussions on these “sensitive issues” may not be advisable.

 

Welding of these alloys (304L and 36L) has to be very controlled, regulated and to be done in clean room. Ferrite in the weld should not exceed 2%, or else meeting impact and lateral expansion properties would not be possible.

 

Meantime if you want to know more about these materials and their low temperature properties, feel free to refer the document as below.

 

Thanks.

Dear Experts,

Currently I am working on a project of ISRO (Indian Space Research Organisation) for Integrated Cryogenic Engine Testing Facility (ICET), for bidding in that services are Liquid Hydrogen, Liquid Oxygen, Liquid Helium, Liquid Nitrogen, Gaseous Hydrogen, Gaseous Oxygen, Gaseous Nitrogen, Gaseous Helium.

For SS Seamless Pipes client has given three options for material ASTM 312 TP 304L/ ASTM 312TP 316L/ ASTM 312TP 321. 

Kindly suggest me the suitable material for the same that gives economical and best design.

 

Thanks in advance.

Re: [MW:34105] SA266 GR4N 4 Cycle SPWHT

By Materials & Welding
Hi,  You are correct, Minimum refers to the one cycle for which this part will expose until final work shop PWHT. hence mill test certificate shall include this.  Max. SPWHT, refers to additional cycles of heat treatment that are reserved for future repairs during equipment lifetime.  Again, these simulated no. Of cycles shall be specified in MTC.  The idea is we need to make sure that steel mechanical properties are not compromised upon exposure to multiple repairs (i e 4 cycles in your case).  One could say, if steel is subjected to 4 cycles and is ok, then it should by defacto be good for one cycle, yet, this is wrong assumption cause mechanical problems and microstructure of materials varies accordingly based on no. Of cycles for which material will expose. This is apparent in alloy steel and especially for impact test values as an example.  In your case, this forged CS with properties before PWHT can be understood to be " as forged" condition (i.e. Wit...

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...
