ASME NM.1 + NM.2 + NM.3 + ISO 15494 + DVS 2207 Thermoplastic and Non-Metallic Piping System Standards: Design + Fusion Joining Reference for Chemical Processing, Water Treatment, Semiconductor, and Pharmaceutical Non-Metallic Fluid System Fabricators<\/h1>\n

ASME NM.1 (Thermoplastic Piping Systems) + NM.2 (Glass-Fiber-Reinforced Thermosetting-Resin Piping Systems) + NM.3 (Nonmetallic Materials) + ISO 15494 (Plastics Piping Systems for Industrial Applications) + DVS 2207 (German Welding Society plastics welding rules) is the non-metallic piping design + fusion joining standard family \u2014 governing chemical processing + water treatment + semiconductor ultra-pure water + pharmaceutical WFI + food processing + mining + waste water treatment plants where non-metallic piping (polyethylene HDPE + polypropylene PP + polyvinyl chloride PVC\/CPVC + polyvinylidene fluoride PVDF + polytetrafluoroethylene PTFE + fiberglass reinforced plastic FRP\/GRP) is preferred over metal for corrosion resistance + weight + cost. Non-metallic piping uses fusion joining (butt fusion + socket fusion + electrofusion) or adhesive bonding + mechanical joint instead of arc welding. ASME NM.1 extends the ASME B31 series (per Batch 22-27 pressure piping) with thermoplastic-specific rules. This guide is the ASME NM.1 + companion standards reference.<\/p>\n
