Types of pipe clip available for low carbon steel tubes

Low carbon steel pipe is a very rigid material, and is heavier than most types
of pipes and tubes. The clips and fastenings need to be capable of carrying
the weight of the material. Because of this, the clips available tend to be very
robust. The types of clips and fastenings for low carbon steel pipe are limited.
For fixing to walls, cast steel school board clips are recommended.
p Figure 2.49 Anchor bolt
Since most low carbon steel is used in industrial installations, the use of munsen
rings and tapped rod is recommended; these can be used with backing plates or,
if being hung from a ceiling, with anchor bolts.

The clipping spacings for low carbon steel are listed in Table 2.33.
