Greenaway Pipeline Products Limited offer a full range of Malleable Iron Pipe Clips, Clamps, Brackets and Backplates for use when supporting Steel Tube to EN10255 (formerly referred to as BS1387 Steel Tube). These Clips and Brackets are available in both Black (Self Colour) and Galvanised finish, and are made from Blackheart Malleable Iron material.

Sizes range from 1/4” (8mm) nominal bore to 6” (150mm) nominal bore, dependant on the product type. The original British Standard specification of BS1494, though now withdrawn, is still followed closely throughout the current manufacturing processes adopted in the Far East. This former specification referred to dimensions, product material and galvanising finish. The Munsen Rings or Pipe Rings (Single or Double Bossed), Screw to Wall or Screw on Brackets and Backplates are still manufactured using Blackheart Malleable Iron material.

- How can we help? -

    The term Blackheart refers here to the type of Malleable Iron that is produced during the casting process. This is made by annealing White Iron in a neutral atmosphere at a temperature of 900 degrees C. It is renowned for its strength. The British Standard for Blackheart Malleable Iron is BS6681:1986.

    The finish of the ‘Hot Dipped’ Galvanised pipe fittings product meets the standard of EN ISO 1461. Products, where possible are also independently tested here in the UK to obtain Breaking Load and Safe Working Load (SWL) information. The Single and Double Munsen Rings or Pipe Rings and Split Clamps are produced with a threaded female boss that is available in Metric or BSP thread to suit different applications. 

    We also offer a Roller and Chair Assembly for use when facilitating expansion and subsequent movement of the Steel Tube. These products when combined are surface mounted and can accommodate Steel Tube up to a dimension of 10” nominal bore.
