Monoweld products

The Hex monoweld is used on upstream offshore/onshore gas and oil production and initial processing installations. Typically used on single or dual gauge pressure or analyzer installations to minimize the size and weight of the pipe-valve assemblies used for primary and/or secondary isolation, vent and calibration. Also used in downstream oil and gas refining and petrochemical production on welded, or flanged pipe processes, primary on gas applications or light end liquids.
