Sliding shoe for insulated pipes SSG 7151
This edition differs from the previous one in that the dimension range has been increased by Dk 711-1219. New strength calculations have been carried out in accordance with the Inspecta report no. 06-267300-00. Load limits for temperatures +20°C - +300°C have been introduced and dimension of the h dimension has been adapted to SSG 7149. New material designations and standard references have been introduced. Sliding shoes in accordance with this standard are used as elements for sliding supports, guides and fixing units in accordance with SSG 7005 - Type 11B, 12B, 13B, 14B, 15B and 36B. In the case of uninsulated pipes or pipes insulated for personnel safety, sliding shoes in accordance with SSG 7149 shall be used. For the selection of sliding shoes refer also to SSG 7005.
Construction
Sliding shoe made of pipe clamps SSG 7075E, T section and angle. The longitudinal tolerance for T sections and angles shall during manufacture be adjusted so that bolts can be mounted in clamps.
Material
Steel S235JRG2 as per EN 10 025 (SS steel 1312). At temperatures above 350°C the slider shoe must be manufactured from heat-resistant metal.
Surface treatment
Hot-dip galvanization as per SS-EN ISO 1461. As the temperature exceeds 200°C, we do not recommend galvanizing as the properties of the zinc deteriorate strongly and the outer surface becomes brittle.
