Requirements for the installation of pipe supports and hangers
Thread Content
There are pipes with a diameter of 273 on the equipment, and these pipes run over long distances (about 20 meters) without any supports or hangers. Are there any standard requirements in this regard?
20 meters. Is there a slope? Otherwise it will sag and water accumulation is likely to occur
The pipeline runs out from the top of the equipment, descends vertically for 6 meters before splitting into three branches; each branch then extends another 8 meters in its respective direction. There are no supports or hangers installed along the entire pipeline
It is preliminarily judged that the flexibility of the pipeline is acceptable, but load-bearing supports must be added. It is best to conduct a stress analysis before selecting an appropriate location for the support, and it is also necessary to consider whether the equipment is vertical or horizontal, as the thermal displacement of the pipe openings differs between these two configurations. For vertical equipment, a load-bearing support should be installed on the outer wall of the equipment near the pipe outlet to reduce the stress on the outlet; for horizontal equipment, it is necessary to find a way to install a load-bearing support on the floor slab. If the temperature is high, it is still recommended to conduct a stress analysis; spring supports are likely to be necessary, otherwise leakage may occur at the pipe flanges due to excessive stress.
Take a look at SH 3073-2004-T, the Design Code for Supports and Hangers in Petrochemical Pipelines
It has exceeded the allowable span requirement for pipes; supports should be installed
The fourth floor mentioned it in a very professional manner; a stress analysis should definitely be conducted. A bracket should definitely be added
If you need to design pipe supports and hangers, our company is a specialized manufacturer in this field – Yongcheng Pipe Support Co., Ltd. located in Sheyang County, Jiangsu Province. Peng Mingxing: 0515-82356556
The bracket is definitely necessary; the description on the fourth floor was very professional. The load on the supports also needs to be determined based on the pipe wall thickness, medium density, insulation, etc. If it is a hot pipe, software should still be used to calculate the thermal displacement in order to determine whether a spring is needed.

The advertisement upstairs is way too excessive; the moderator should take action.
The allowable span of a pipe is determined by factors such as the pipe’s wall thickness, diameter, the medium inside the pipe, and whether insulation is present. If the medium inside the pipe is a liquid and no insulation is used, the pipe is calculated based on stiffness considerations, with a maximum span of 11 to 14 meters. Therefore, if this pipeline has no support structures within a range of 20 meters in a horizontal direction, it certainly does not meet the regulatory requirements.
