NI-HARD Wearback Corner

Key Features

  • Heavy duty castings maximise operating life
  • 90° and 45° bend configurations
  • Replaceable wearback design has wear-resistant rubber gasket as standard
  • Flange faces machined in-house for repeatable quality control

To cope with a whole list of abrasive materials including sand, cement, quarry dust, granite dust, sinter dust, slag, coal and many others which cause extra wear on pipe bends of conventional material, we provide a range of Ni-Hard castings. Standard and special radius plain bends with and without replaceable wear-back plates are available. Flanged ends as standard, although special designs can be considered. Ni-Hard bends are essential for the efficient conveying of abrasive materials.

All dimensions are in mm unless otherwise stated

Mating flanges should always be offered up to the NiHard units in a parallel and close fitting position. No undue strain should be imparted on the flanges by pulling up with bolts, as damage to the casting may result.

Due to the issues highlighted above, we recommend that the bends are installed against flat face flanges. If this is not possible, then appropriate spacers / gaskets should be used.

3 mm / 1/8” Full Face Rubber gaskets should be used between flanges (flat face).

Maximum torque for bolt tightening should be 67.8 Nm or 50 lb/ft.
