This is the question of whether or not the pipe rack will support equipment such as Air Coolers (Fin Fans).There are so many situations that a pipe can find itself in and in every case it will need to be supported.There is what I call the primary pipe support systems, and then there are the secondary pipe support systems.The primary pipe supports systems are those supports that are a part of the infrastructure and fall under the prime responsibility of the structural department.
The secondary pipe support systems are more a part of the piping systems and as such fall under the prime responsibility of the piping department. You notice I used the words prime responsibility with each of these there is still a cross over responsibility to provide proper, accurate and timely information and then action. Primary Pipe Support Systems As noted above the primary pipe supports are a part of the infrastructure. These primary pipe supports systems may also be referred to as piperacks, pipeways, pipe alleys. These support systems may be major or minor and they may be overhead or sleeper pipe racks. It is important to understand that even though they are called pipe racks they support and carry more than just piping. For clarification, overhead pipe racks are elevated to the point where you can walk andor drive under the supported piping. Sleepers or sleeper ways are low to the ground so there is no passage under the supported piping. Pipe racks (overhead or sleeper) are normally established and sized early in the preliminary engineering phase of a project. This time of the project is normally called the plant development phase or the plot plan development phase. Once they are established and sized they are one of the first things the structural department can work on. The terms establish and size requires a lot of wisdom and work. The wisdom and work means thinking one, two or three years into the future and deciding where (location) the primary pipe support systems will run. Other critical elements include the configuration, height, width, spacing and the materials of constructionfabrication method. Location In order to set the location of the primary pipe support systems the total plant layout must be established. This means that all the various disciplines must have a very good idea what equipment is required and its size. The Plot Plan must be reviewed by all the key people on the project and then approved by the client. Each main run, minor run and branch run must be looked at to determine its configuration. Will it be an overhead rack or a sleeper way Will each be single deck (layer) or multiple deck Will the support be a single column (T) support or multi-column support How many columns A second part of the configuration issue effects pipe racks in the process units themselves.
