1 ScopeThis Uhde standard specifies for the user the design dimensions and total weights of the riser pipe clamps for

uninsulated and heat-insulated (riser) steel piping.

See Uhde standard UN 3786-01, for the summary, dimensions and standard part numbers of the sub-assemblies.

The allowable loads are specified in Uhde standard UN 3786-01, supplement 4.
