NOTE 1. This support is suitable only for nominally horizontal sections of pipe lines. When using this type of support consideration shall be given to problems related to possible in-service damage to the pipe thermal insulation in the vicinity of the support. NOTE 2. Range D1 gives dimensions for pipe clips using BS 1501: 620 grade 27B (1% Cr, ½% Mo) material for use for maximum temperature of 510ºC. Ranges D2 and D3 give respectively, dimensions for pipe clips using BS 1501 : 620 grade 27B (1% Cr, ½% Mo) material for use for maximum temperature of 540ºC and BS 1501: 622 grade 31B (2¼ % Cr, 1% Mo) material for use up to 570ºC. NOTE 3. Asbestos free tape or millboard may be placed between the pipe and the U-Strap. In such cases, the dimensions of the U-Strap shall be adjusted to ensure that it does not tighten on to the pipe.
