CS in place of LTCS

[yogesh]

Can we replace LTCS with CS if temperature minimum expexted is
-20DegC,process fluid;Coolwing water???

Dear All,

 

          Can anybody tell me the Material A516 Gr. 55 is C.S or LTCS?

Thank's,

Dear Mr.Azaz, SA 516 Gr.65 is low temperature carbon steel material used for moderate and lower temperature service and its having impact test properties. Regards, Thiru. --- On Thu, 27/1/11, Ayaz Mahmood <tigerhe...@yahoo.com> wrote:

hi

If cooling water , then the CS pipe tested with impact and the
temperature should be more than your fluid temperature . if the fluid
temperature is (-))10 deg C then your base metal should be at least (-)
20 deg C. in this way your CS is there then you may replace or you have
to go for LTCS.

Hi,

SA 516 Grades all comes under (SPECIFICATION FOR PRESSURE VESSEL
PLATES,
CARBON STEEL, FOR MODERATE- AND LOWER TEMPERATURE SERVICE)

while ordering you have to mention the requirement in supplementary
S5. Charpy V-Notch Impact Test,then you will get LTCS.

@ CS in place of LTCS

 

i mean to know if we are taking well care of low temperature/using impact tested CS ,then CS would be a better metallurgy than LTCS or not because LTCS is having (Cr+Ni) ,certainly having better properies than CS in terms of corrosion????

 

Any experience of repl;acing LTCS tubes with CS tubes in heat exchanegrs is appreciated.

Can any body tell me what is LTCS and its full form.

[ramu ramalingam]

what is the difference between CS & LTCS material.some time material heat numbers were both in one manufacturing and chemical and mechanical both are same in both materials.but one had impacted.Is it ok? Material can be used in production?

[james gerald]

LTCS is low temperature carbon steel which can be used at low temperatures according to the applicable specification. Yes is the answer to your query if impact tested at the required temperature.   J.GERALD JAYAKUMAR 00919344954677   --- On Tue, 2/22/11, ramu ramalingam <ramu....@gmail.com> wrote:

Dear!
LTCS and CS differ by Heat treatment while manufacturing.
LTCS shall be treated to control their microstructure accordance with
varies temperature and some chemical composition changes between those
materials... LTCS material using for low temp. services...

Can anybody clear could we use this LTCS for high temp. services??

[naran...@aol.in]

No the material ltcs essentially fine grain steel,usually has little higher mn. You should. Not change the material either way.

[james gerald]

Normally the Designer selects materials for High Temperature or Low temperature based on the allowable Stress values of the Applicable Code like ASME Sec.IID or ASME B31.3

For Piping,for High temperature applications we select ASTM A106 Gr.B & for low temperature applicable one may select ASTM A 333 Gr.6. This is only an example.

The Chemistry and Heat Treatment requirement shall comply with the Applicable Material standard/specification like A106Gr.B or A333 Gr.6.

If the Heat number is same and all the requirements of the specifications are complied, then it is considered acceptable.
