Titanium Plate Flange PL DN40 RF ANSI B16.5
Titanium Plate Flange PL DN40 RF ANSI B16.5
This titanium plate flange (PL type) is a forged, CNC machined part with a raised face, made to DN40 and the ANSI B16.5 standard. A plate flange bolts to the mating flange through the pipe wall, which gives a simple and compact joint for low to medium pressure lines. The forged body is dense and free of porosity, the polished face lets the gasket seat evenly, and the raised face concentrates the bolt load where the seal is needed. Titanium resists chlorides, sea water and many acids and weighs about half as much as steel. Each part is checked by ultrasonic testing and shipped with a material test report to EN 10204 3.1.

Product Picture
Applications
The plate flange is fitted where a compact, corrosion resistant joint is needed. Common uses include process plant piping, pump and valve connections, water treatment and desalination lines, oil and gas service, chemical handling equipment, marine pipework and general engineering. Because the size, pressure class and face can be produced to the drawing, the flange can be matched to existing pipework and gasket standards. Each batch is checked for dimensions, face finish and material before packing in wooden cases for export.
