U Hangers.Supporting pipe risers subject to thermal expansion and contraction in hi-rise HVAC Systems has presented tremendous problems to the Design Engineer.

Standard carbon steel piping expands or contracts at a rate of 0. Solutions for accommodating this movement include horizontal expansion loops or incorporating expansion joints and several anchor points.

These methods may be adequate, but there are many negative features. The use of horizontal expansion loops Figure A can result in the need for higher horse power pumps to overcome the additional friction and directional change in the horizontal runs. The additional horizontal piping adds to material and labor costs and may reduce the amount of rentable space as the pipe leaves and returns to the riser chase.

Prior to the introduction of stainless steel or rubber expansion joints Figure BDesign Engineers had no choice but to incorporate expansion loops and anchors. Expansion joints enabled the Engineer to keep the riser straight, but potential failure became an issue. The failure of an expansion joint means not only loss of heating or cooling, but a good possibility of extensive water or steam damage. In order to periodically inspect the expansion joints, they must remain accessible and this is not always possible.

Additional valving becomes a necessity for rapid shut down or maintenance. Valves are both expensive and slow to close to avoid water damage.

Both expansion joints and expansion loop systems require multiple anchor points which present the Design Engineer with yet another difficult task.

The loads on the anchor pairs can be quite high when coupled with the forces to move the expansion loops or expansion joints plus expansion joint thrust. Large safety factors become advisable for both anchorage and structural supports. Figure C. The spring support systems can be designed to utilize a central isolated anchor which remains neutral during operation, or a totally free-floating system with spring support only.

If a single anchor is used, it is located as close as possible to the middle of the riser to direct the pipe to expand away or contract towards the anchor point. By locating the anchor in the center of the riser the expansion and contraction at each end is cut in half. Unanchored or totally free-floating systems are designed to expand or contract from the center as well, but control is far more difficult as branch off and end stiffnesses are difficult to calculate and installations must be closely watched to avoid accidental movement restrictions at branch offs.

In addition, when water weight is removed for equipment maintenance, an alternate restraint method or individual mounting readjustment may be required. Depending on the support structures strength, the number and location of spring mounts may vary from one set on every floor for maximum load distribution or they may be spaced at greater intervals. Isolated pipe guides should be used in most systems to maintain alignment of anchored or unanchored spring support systems.

Risers can be butt welded when installed to assure integrity. They are easy to install and require no maintenance.

Standard Pipe Supports

Most importantly, the load at each support point is known under all conditions, i.A pipe support or pipe hanger is a designed element that transfer the load from a pipe to the supporting structures. The load includes the weight of the pipe proper, the content that the pipe carries, all the pipe fittings attached to pipe, and the pipe covering such as insulation. The four main functions of a pipe support are to anchor, guide, absorb shock, and support a specified load.

Pipe supports used in high or low temperature applications may contain insulation materials. The overall design configuration of a pipe support assembly is dependent on the loading and operating conditions. Just as the primary loads have their origin in some force, secondary loads are caused by displacement of some kind. For example, the pipe connected to a storage tank may be under load if the tank nozzle to which it is connected moves down due to tank settlement. Similarly, pipe connected to a vessel is pulled upwards because the vessel nozzle moves up due to vessel expansion.

Also, a pipe may vibrate due to vibrations in the rotating equipment it is attached to. A pipe may experience expansion or contraction once it is subjected to temperatures higher or lower respectively as compared to temperature at which it was assembled. The secondary loads are often cyclic but not always. For example, load due to tank settlement is not cyclic. The load due to vessel nozzle movement during operation is cyclic because the displacement is withdrawn during shut-down and resurfaces again after fresh start-up.

A pipe subjected to a cycle of hot and cold fluid similarly undergoes cyclic loads and deformation. Rigid supports are used to restrict pipe in certain direction s without any flexibility in that direction. Rigid support can be provided either from bottom or top. In case of bottom supports generally a stanchion or Pipe Clamp Base is used.

It can be simply kept on steel structure for only rest type supports.

To simultaneously restrict in another direction separate plate or Lift up Lug can be used. A pipe anchor is a rigid support that restricts movement in all three orthogonal directions and all three rotational directions, i. In this type of support, normal force and friction force can become significant. It is a static restraint i. It is rigid vertical type support provide from top only.

It consists of clamp, eye nut, tie rod, beam attachment. Selection of rod hanger depends on pipe size, load, temperature, insulation, assembly length etc. As it comes with hinge and clamp, no substantial frictional force comes into play. It is a dynamic component i. V-type Strut can be used to restrict 2 degrees of freedom. It consists of stiff clamp, rigid strut, welding clevis.

Selection depends on pipe size, load, temperature, insulation, assembly length. Spring supports or Flexible supports use helical coil compression springs to accommodate loads and associated pipe movements due to thermal expansions.

The critical component in both the type of supports are Helical Coil Compression springs. Light springs are normally cold formed Heavy springs are manufactured by the hot coiling process. Variable effort supports also known as variable hangers or variables are used to support pipe lines subjected to moderate approximately up to 50mm vertical thermal movements.Pipe is held either from above by hangers or supports of various types on which it rests. Hangers are also referred to as supports. There are a number of typical pipe supports that can be installed to support dead weight loads, and restrain the pipe for thermal and dynamic loads.

The designs are only limited by the imagination of the engineer and designer, as literally thousands of different designs have been used for special purposes. Pipe is rested on or secured to a support member usually of a standard structural shape I-beam, wide flange beam, angle, channel etc.

The pipe may be secured to this member with a pipe support. Pipe supports and hangers are devices which transfer the loads from the pipe or the structural attachment to the supporting structure or equipment.

They include rod hangers, spring hangers, sway braces, turnbuckles, struts, anchors, saddles, rollers, brackets, and sliding supports. Structural attachments are elements that are welded, bolted, or clamped to the pipe, such as clips, lugs, clamps, clevises, and stops.

The correct and economical selection of the supports for any piping system usually presents difficulties of varying degrees, some relatively minor and others of a more critical nature.

Proper support selection should be the objective of all phases of design and construction. Support locations are dependent on many considerations, such as pipe size, piping configuration, the location of heavy Valves and fittings, and the structure that is available for support.

Following rules of thumb will help when doing the flexibility analysis and operation and maintenance:. The anticipated movement at each support point dictates the basic type of support required. Each type of support selected must be capable of accommodating movements. It is a good practice to select first the most simple or basic rigid support type and to add to the complexity only as conditions warrant.

No advantage will be realized in upgrading a support when a simpler, more economical type can be shown to satisfy all the design requirements. Both vertical and horizontal movement must be evaluated. When piping vertical movement is small, the use of simple rod hangers should be adequate. When one is calculating the total movement experienced by the support, both horizontal displacements and the vertical displacement must be combined and normalized to the axis of the support.

Consideration should be given to relocating the upper connection some percentage usually two-thirds of the total movement as a means for reducing the angularity in the hot position.

For piping supported from below, some form of slide must be incorporated to provide for the horizontal movement; or, in the case of ensured longitudinal movement, a pipe roll may be used.See popular blocks and top brands.

Sliding Drawing elements Entertainment A pipe line needs to be supported from a foundation or a structure. This type of support arrangement is generally very simple and has maximum use in piping. It does not have adjustability to the erection tolerances.

It will directly rest on foundation or structure which is supporting the pipe. This type of support is commonly used for supporting hot piping. It shall be able to support pipes even when the pipe is moving up or down at support point. Common types of elastic supports are variable type spring supportsconstant type spring supports.

This type of support is Rigid type in construction but is has few nuts and bolts arrangements for adjusting the supports with respect to the actual erected condition of pipe. The support can be adjusted for the erection tolerances in the piping.

This is most commonly used support meant for supporting only the pipe weight vertically. It allows pipe to move in axial as well as transverse direction but restricts only the vertical downward movement. This type of support is used to restrict the movement of pipe in transverse direction i. This is also a commonly used type of support. Generally it is used along with Loose support. This type of support is used to restrict the movement of pipe in longitudinal axial direction but allows the pipe to move in transverse direction.

This type is less used as compared to above two types. ANCHOR type of support is used to restrict movement in all three directions and rotation also in these three directions.
