The document discusses high pressure pipe fittings that are designed for high pressure networks used in chemical, petrochemical, and hydraulic processes. There are two types of fittings: threaded mechanical fittings according to ANSI B1.20.1 and welded fittings. The 3000 lbs series is the most common range, with tube standards of Schedule 80 (150 bars) and Schedule 160 (320 bars). Internal diameters and dimensions are provided for welded steel union fittings.
