Cryogenic Basket Strainer for LNG- leg Support length requirement 1

[DrunkEng]

Hi we are using a 12" Basket Strainer for Cryogenic service medium is LNG.It has Cold Insulation.

1) I want to know is there any length requirement for Leg Support for the cryogenic Temperature requirement.

2) Is there any reference regarding this.

3) Is it compulsory to use wooden Isolation block on the support.

Drawing?

I assume you mean you have a metallic support coming from the filter.

The longer the better is the short answer.

No reference I know of.

Not "compulsory", but it is a good design practice to allow a thermal break somewhere in the support system otherwise a LARGE ball of frost will appear over time and / or continuous condensation which causes a lot of corrosion. Wood is actually a very good insulator with some significant strength - plywood seems to be the best.

please refer to GA

Currently we have 400 Support length and the strainer body has a cold insulation of 170mm thickness.

It will be a cold breach and will either drip water constantly or grow a large ice block.

LNG is very cold and you really need to introduce a thermal break or add a wooden plate under it and insulate the support all the way to the floor. IMHO.

How are the normal pipe supports insulated?

Any line stops or anchors where a similar thing is happening?

For pipes we are using insulated Cold Pipe Shoe

THis is the first time we are using a basket strainer hence trying to find reference.
