A piping system needs to be supported from some foundation or from a structure nearby. The whole weight of the Piping network is transferred to those Civil foundations or Structures. In a piping support system, some supports are directly attached to pipes while some support types are not.
Based on the attachment of Support to pipes there are two types of Support in the Piping Support System:
Primary Supports: These types of support are directly clamped or welded to pipes for their resting. For example Shoe, Saddle, Pipe Hanger, Wear Pad, Trunnion Etc.
Secondary Support: These are the type of support which not directly connected pipes but connected to either civil foundations or Structural members. With the help of these secondary supports, Primary support rests on its location. Antifriction Pad, Limit stopper, Guide, Goalpost are some of the examples of secondary supports.
What is shoe support in piping?
Pipe shoes are a type of pipe support that elevates piping and insulates pipes from beams or other surfaces. … A quality pipe shoe will stop thermal expansion, which causes movement, high friction points, and damage. They do this by separating piping from metal structures that encourage heat transfer and ice formation.9
Guides.
When total restriction of pipe movement is not required, pipe guides are used. Pipe guides confine movement along the pipe’s lineal axis. In piping terms this is called a sliding point. They are used primarily to maintain proper line spacing in a pipe rack and they prevent lateral or sideway movement.
Anchor support
A Pipe anchor support is a rigid device that completely restricts pipe movement in all three dimensions while bearing the weight, side, and thrust loads. It is designed to prevent essentially all pipe rotation and displacement at the point of application.
Saddle support.
A saddle support is a support consisting of a stanchion that utilizes a curved section for cradling the pipe. Adjustable Pipe Saddle Supports.
Pipe sleeper.
The precast concrete sleepers feature recessed lifting units which allow safe and easy handling. The concrete pipeline sleepers can also be manufactured with imbedded threaded anchors, steel plates, pipe saddle supports, hold down pipe clamps, and other hardware used to anchor the pipeline to the sleeper.
Dummy Supports
By contrast, a dummy support consists of a full piece of pipe that you weld to the back of an elbow. It props up your elbow and forms a bridge between the point where your pipe run changes direction and your closest support.
Spring support.
We refer to our spring supports as any assembly which includes a spring(either variable or constant) that can accommodate both a pipe load and a pipemovement.
Line stop support.
Line stops are used to redirect thermal expansion. They are particularly useful when you are in pipe racks or have long runs that include an expansion loop. Note that when using these supports, pull the moments at the support node to report back to structural as an overturning moment will be created.
What are roller support.
A roller support allows rotation about any axis and translation (horizontal movement) in any direction parallel to the surface on which it rests. It restrains the structure from movement in a vertical direction. The idealized representation of a roller and its reaction are also shown in Table 3.1.
- The basic parameters for support selection guide are as follows:
Process design conditions.
Pipe material of construction.
Piping Loads including Piping weight, fluid,weight, Valves,inline instruments etc.
Insulation material,thickness,density & specification.
Piping General Arrangement drawing.
Clamped Type Supports
Piping Clamp Support
Clamped type supports are defined as the support mechanism for suspended pipes either in horizontal or vertical conditions. Pipe clamps come in many variations as per the requirement of the piping system.
Welded Type Supports
Welded Supports
Supports that are directly welded to pipes are defined as welded-type supports. These types of supports are less susceptible to corrosion with respect to clamped supports. As some exception in the following cases welded types supports are not advised to use:
Pipe Saddles and Reinforcement pads
Saddle supports
Saddle support is a structure consisting of a saddle and integral base that is used to support the pipe by transmitting the load or force to the adjacent structure.
Secondary Support
Secondary supports are a type of supports used in piping that doesn’t take a direct load of pipe but transfer all load of pipes to adjacent structural or civil members. This Support is made from steel structural members like Angle, Channel, Beam, and Plate as per support location requirement.
