What should be considered in steam pipeline design? Pipeline routing/support selection? Please, experts, give me some advice
General Manager, I suspect your account has been hacked. First, there is a concern about getting burned, and secondly, thermal expansion and contraction are taken into account.
Pay attention to selecting the materials based on the parameters; steam pipes should have a slope, and the supports must be chosen in a suitable form based on calculations – either spring-type, rigid, or guiding type. The alignment of the pipes should not be too rigid, as flexible compensation needs to be taken into account. . . . . Better go check the specifications.
Determine whether the steam is superheated or saturated in order to set the steam trap location; be careful to avoid water hammer. For thermal pipes in pipe racks, the top layer should be given priority. Choose an appropriate pipe layout based on the pipe temperature, diameter, and material to enhance flexibility (L-shaped, N-shaped, π-shaped, etc.). Install pipe supports according to the different pipe layouts and the potential deformations they may cause. There is also the selection of materials for pipeline insulation thickness. Steam drum setup, drain point placement, placement of drain points at the inlet to the device, whether condensate recovery is to be done in a closed or open system, design of the valve assemblies for converting superheated steam to saturated steam... It is recommended to refer to the Power Piping Design Manual
Let’s see what industry you’re in Electricity has its own set of standards, and national standards also include industrial guidelines regarding steam pipelines.
Clause 9.1 of SH3059-2011 specifies the layout requirements for steam pipelines in the petrochemical industry.
