Malleable iron bend 30° Rp - R

  Datasheet (PDF)

The Georg Fischer Fig. 50 malleable iron 30 degrees bend provides reliable angular redirection in heavy-duty threaded steel piping networks, permitting smooth directional adjustments while preserving hydraulic efficiency and laminar flow characteristics. Manufactured from high-grade decarburised annealed whiteheart malleable cast iron conforming to EN-GJMW-400-5 and EN 10242 design symbol A, the structural fitting combines exceptional mechanical tensile strength with high ductility under thermal cycling and vibrational stresses. A premium hot-dip galvanised protective coating, executed with high-purity zinc, establishes an alloyed multi-layer barrier that shields the core iron against oxidation and corrosion, ensuring full conformity with potable water installations as well as gas, compressed air, oil, and non-aggressive industrial fluids. The fitting is configured with an external taper jointing thread (R) on one end and an internal parallel jointing thread (Rp) on the opposing end according to EN 10226-1 and ISO 7-1 standards. When tightened, the progressive metallic flank compression between the taper male and cylindrical female threads creates a dependable, pressure-tight mechanical joint with sealing engagement in the thread profile when paired with approved sealing media. Designed for working pressures up to 25 bar across temperatures between -20 and 120 degrees Celsius, and rated up to 20 bar at operational peaks reaching 300 degrees Celsius, the 30 degrees geometry allows installers to navigate obstacles and offset pipeline axes accurately. Its engineered geometry incorporates standardised z-dimensions to simplify centre-to-centre isometric layouts, enabling accurate prefabrication, reduced assembly time, and reliable integration across commercial, agricultural, and industrial utility installations.
