Thank you akpipelinegr, sounds good. Not too far from our site[thumbsup2]

GD2, tq for yr offer but we need stockist not import.

Hello, can anyone recommend a good stockist for CS 1/4" to 2". Site is in state WA. Quantity is a few hundred meters different sizes. Thanks

Krausen, theoretical possible for long tern use but right now it is commissioning and they want to run the system

Hello, we have flexible hoses in SS for high temperature exhaust gases (mainly nitrogen) up to 1200°F. Does anyone has experiences with one of the following sealants X-Pando, Deacon 8875-Thin,Flexitallic Graoil GTS and Loctite NS 5550? Is any of these sealants long lasting and can hot/cold...

Hello, we have flexible hoses in SS for high temperature exhaust gases (mainly nitrogen) up to 1200°F. Does anyone has experiences with one of the following sealants X-Pando and attached products such as Deacon 8875-Thin, Flexitallic Graoil GTS and Loctite NS 5550? Is any of these sealants...

dvd, Client insist of welding since the media is Monosilane which ignites immediately at ambient atmosphere. Even PITs are welded and need to be cut our once damaged.

Some more information. Sizes are 1-1.5" in 316. We finally used a bucket of water since the short pipe spool fit in.https://files.engineering.com/getfile.aspx?folder=a41a9191-0a25-4150-9dd6-121bcea44c74&file=IMG_20240506_100447.jpg

Hi DVWE, that's the only I agree. We do carefull welding now and let the valve cool down. Alternatively we used a wet rag and kept the body cool.

TugboatEng, The design was chosen due to the process parameters; 100% welded and gaskets acc. to media requirement. No alternative possible.

Dear All, what is the common practice to socket weld valves with internal gaskets e.g noeprene, N-Butan. The heat impact can damage the gaskets. The supplier does not provide a clear instruction other than "use heat sink or other method to avoid damage". There are many ways to do it but what...

Thank you everyone, was helpful

Why is that DVWE. I am neither a welding engineer nor a welder. Thanks

Yes it could be done but very time consuming.Weldolet would have been the right choice. But the project is in Czech and will be done for US so it is difficult to get ASME fittings from stock.

r6155. Yes I agree but now we have to find a solution. Thanks for your input.

Dear All, our contractor looks for a common way how to weld a 3/4" pipe (304) into a 3/4 "sockolet (304). The gap between sockolet and inserted pipe is to small (~0.1mm) to purge the oxygen completely with forming gas. There will be a risk of crevice corrosion. The pipe (3") uses many sockolets...

LittleInch, good explanation. Thanks

1503-44 The dimesnion of the gasket 3"-150 is ID 3.5" (89mm) However, the flange 3"-150 ID is 77mm. Yes I agree you can have pipes 3" with extra thick wall thickness but the flange remains the same.

Dear All, can someone provide me with a technical explanation why the flange seal face is not fully utilized by the gasket. I know the dimensions for the shown flange 3" RF 150 and the gasket 3" are both correct acc to the ASME code. What is the reason not matching the inner diameter of the...

Thanks TiCl4, That's a good idea.
