Has anyone used a "hydratect" fitting before? It is a level switch used for steam service. The physical connection relies on stubbing the fitting into the steam header. The problem is that the only option offered by our vendor is 316SS and our header material is CS. We used a 309L electrode...
On the advice of a Vendor, we have welded a 316SS piece (essentially pipe) directly into a CS header pipe (DN300 Sch 40) in temperatures operating up to 400degC. Using a 309L electrode.
When we do our finite element analysis of the junction, we see yeilding (at operating temp) local to the...
Does anyone know of a guide for the warm-up rates for steam systems? I cannot find anything in ASME B31.1 or Spirax publications.
I am purposefully not giving details because I am after guidelines not specifics. However, it should be noted that the systems in question are in industrial power...
We have specified SS treaded valves to be installed in CS systems on a large sugar project. Many of these are in aqueous service. We were trying to standardise our valves as much as possible. The pressures are minimal and the fluids are non-hazardous. The valves are all less than or equal to...
I have two questions:
1. I am trying to find a supplier of pipe clamps for vibration. There are many clamps on the market that are simply a bent plate. The clamps I am seeking have long lugs for the bolts either side so that they are much stiffer. I have seen these in recommedations by Beta...
