thanx for quick reply/Try !
you write “when steam condenses it becomes pure water. And that is where SS comes in. You will see that’s the case”
Boss even in the sampling case it will remain in the gas phase only …it has same parameters as of Live steam …thats why the drains of main steam line are of alloy steel……but sampling line are of SS….that is making the selection of material slightly anomalous here………
i guess the variation in material selection is related to size .
but both alloy steel and stainless steel are available as per the code ASME36.10 & ASME36.19 in DN10 size .
