Just did some checking. Are you referring to this link:

www.process-heating.com/archives/1099feature.htm

<<How to Build a Reliable, Practically Leak-Free Thermal Fluid System Process-Heating.com>>

<<If you are concerned only with minimizing leaks, a properly designed and installed all-welded system will provide much better leak protection than a system with flanged and screwed connections. How-ever, the trade-off with an all-welded system is a decided lack of flexibility for maintenance operations. For example, while it is possible to repair or rebuild a valve inline, it is much easier and cheaper to remove the valve and send it out for repair. In practice, most thermal fluid systems contain a number of flanged and screwed connections - and each is a potential leak point. For this reason (and for the sake of the system operators who will have to deal with any leaks), a thermal fluid system should be designed to include only as many breakable connections as are absolutely necessary.>>

If so, it DOES result in an error message like: _Error processing SSI file '/archives/1099feature.htm'_

Google finds the page but attempts to get there via Google gives the same message. It's likely that the page has been removed by Process-Heating (or their site is being revised) since a search of their site turns up nothing.

In response to your question, flanged connections add weight and cost but enable inline components to be easily removed for maintenance/replacement. Socketwelded fittings are generally used for smaller pipe sizes, say, under 2". What is your process fluid. pressure, flowrate, temperature? These criteria will determine which option to choose.
