Hello, I'm looking for help regarding a pipe class/specification. I need to supply a product that meets the below specification:The product's pressure rating must meet a pressure rating spec of "SDH". SDH piping class is Sch 160 SMLS 2-1/4 Cr A 335 for 1" NPD. Obviously the Sch is 160, the product is 2-1/4 Cro-mo, and for a 1" line size but what's the A 335? What does "SDH" mean? What does SMLS mean? This particular line is a steam line with superheated steam running through it and I need to meet the above specs. ANY HELP would be greatly appreciated.Thanks for your time,Blainetundra6@oanet.com
