Sliding support SSG 7005 type 12
This standard comprises symbols and types for hangers, guides, supports and anchorages for pipelines. These are described in detail in SSG 7005. Anchorage and support elements are described in SSG 7025 - 7179.
The standard is intended for use for piping as indicted below in the dimension range DN 10 - 1200. At fluid temperatures greater than 200°C we do not recommend galvanizing as the properties of the zinc deteriorate strongly and the outer surface becomes brittle. At fluid temperatures greater than 350°C and lower than -20°C, supports must be made from material that is suitable for the calculated temperature and compatible with the piping material or include a suitable thermal barrier.
The standard for sliding supports of Type 12 comprises two types, 12A and 12B. Sliding support Type 12A is designed for uninsulated pipes, pipes insulated for personnel safety and insulated pipes with a maximum insulation thickness of 80 mm. Sliding support Type 12B is designed for insulated pipes. Type 12 is a type 11 with guide lugs. The guide lugs are intended for horizontal piping with natural downward force. Not intended for expansion loads.
