Re: [MW:25818] For Cryogenic Services at Temp -196 degree Celsius (17 Kelvin) Pipe of ASTM 312 TP 304 L is suitable?

Hi,

ASTM 312 TP304L Suitable base on my experience, currently im involved with LNG TANK EPCC,all the pipe work we use 304L.

They are more difficult to weld tham austenitic ss but cheaper. 304 and 316 are more reliable

Dear Vivek,

Please let me share the following info I have on this subject: 

Cryogenic Steel ASTM A553 Type 1 and  Type 2, / ASME SA-553/SA-553M Q&T 8% and 9% Ni-alloy Steel.  

Ideal for containment or transportation of liquefied gases such as LNG, oxygen, nitrogen and argon which need to be stored at a temperatures below -196°C. The material is good for any pressure containing application with excellent resistance to low temperature brittle fracture.

Many of the pressurized storage tanks designed to hold these gases are double walled with an insulation layer to minimise any generation in heat. Considerations should be made not only to the material used but also the fittings required which will also include piping and valves.

Other Cryogenic Steel Grades

You may also consider the following steel grades for cryogenic purposes:

• ASTM A553 Class 1 & Class 2 plates
• ASME SA553 Class 1 & Class 2 plates
• ASTM A353
• ASME SA353

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.
