Depending on the situation, pipes can be supported from above or below. Several common pipe support clamps and hangers can be installed to hold down the pipe for thermal and dynamic stresses and sustain dead weight loads. These supports take pressure off the pipes because straining them too much could result in leaks or fractures, leading to many other issues.
Since thousands of designs have been employed for specific applications, the pipe support clamps and hangers design mostly rests on the imagination of the engineer and designer. For purposes of design, production, fabrication, and installation, certain codes and standards are referenced:
Codes and Standards for Pipe Supports
The following are the main codes and standards for pipe hangers and supports:
- MSS SP-58 – Pipe Supports Hangers: Material, Design, and Manufacturing
- MSS SP-69 – Pipe Hangers and Supports: Application and Selection
- MSS SP-77 – Requirements for Pipe Supports and Hangers Contractual Relationships
- MSS SP89 Fabrication and Installation Practices
- Terminology for Pipe Supports and Hangers – MSS SP-90
Typical Pipe Support Clamps
- Yoke-Type Pipe Clamp
To suspend high-temperature horizontal stationary insulated lines, yoke-type pipe clamps are necessary. This clamp is suggested for insulated lines between 4″ and 6″.
- Three-Bolt Pipe Clamp
A horizontal hotline with thick insulation is suspended using three-bolt pipe clamps, which are made to support loads of moderate size. The pipe clamp can be attached using the three-bolt design outside the insulation. The three-bolt pipe clamp should be chosen based on the load and the line’s temperature.
- Two-Bolt Pipe Clamp
Two-Bolt Clamps are recommended for supporting horizontal lines where little or no insulation is required on the pipeline and the loads to be transported are not of a high entity.
- Adjustable Swivel Ring, Split Type
The split-type adjustable swivel ring is advised for suspending stationary non-insulated pipelines. The self-locking adjustable swivel ring keeps the pipe’s optimum pitch while preventing loosening by line vibration.
- Extension or Riser Pipe clamp
Without hanger roads, vertical stationary lines should be suspended or restrained using an extension or riser pipe clamps. The pipe load is transferred by placing both clamp’s ears on a structural member or floor surface. This pipe clamp’s recommended maximum operating temperature is 343°C.
- Extension Split Pipe Clamp, Hinged Type
Extension split pipe clamps are advised to support non-insulated horizontal lines in conjunction with the pipe nipple. This clamp is specifically designed for use on compressor or refrigeration piping that is subject to vibration. The clamp’s inside structure gives the pipe a firm grasp. The tapering inner ring cannot trap condensed moisture.
- Steel Weldless Eye Nut
A tool made of forged steel that is used to install high-temperature pipework. It offers a flexible connection when utilized with a straight thread rod to a bolt or pin connection.
- Top Beam C-Clamp
The Top Beam C-Clamp is advised for use with joist-type construction, under-roof installations, and attachment to the top or bottom flange of a structural element when it is anticipated that the vertical hanger rod will be offset from the edge of the flange. A cup-pointed set screw tightened against the flange has secured the clamp. A jam nut is provided for tightening the set screw against the body Casting.
- Side Beam Clamp
A slide beam clamp is necessary when the hanger rod must run vertically close to the edge of the beam. It keeps holes from being drilled in the structural member and is fastened to the bottom flange of the member. It may be adapted to various thicknesses and widths of beam flanges.
- Center Beam Clamp
The Center beam clamp is designed to be used in the suspension of the hanger rod from the center of an I-beam and is attached to the bottom flange of an I-beam and prevents distortion.
- Welded Beam Attachment
When loads and rod sizes are particularly considerable, welded beam attachment connects hanger rods to the beam at the bottom of steel beams. To give flexibility or vertical adjustment, it can be fitted. The beam size should not be taken into account.
When the projected vertical load exceeds the horizontal forces, a U-Bolt is employed as a pipe guide.
- Pipe Clip
By fastening the clip directly to a building, pipe clips, also known as pipe straps, are advised for suspending horizontal stationary lines.
- Steel Beam Clamp with an Eye Nut
This component doesn’t need to be welded; it is fastened to a structural member’s bottom flange where the vertical rod must be centered on the structural beam. With the addition of the adjustment facility, this clamp performs the same function as the center beam clamp.
Typical Pipe Support Hangers
- Adjustable Clevis Hanger
A clevis hanger is a pipe attachment that allows for vertical adjustment and the suspension of non-insulated horizontal stationary lines. To prevent the yoke from sliding toward the center of the bolt, the clevis hanger is made with a yoke on the outside of the lower U-strap. This minimizes the amount that the bolt will bend.
- Pipe or Conduit Hanger
The conduit hanger is advised for suspending stationary, non-insulated wires. It can be boated to a wall using the T-slot on the side of the strap or hanging from a hanger rod. After pipe installation and setup, the side bolt can be attached to a T-slot in its hanger.
- Adjustable Steel Band Hanger
Once the pipe is installed, it can be adjusted vertically and an attachment designed to suspend non-insulated horizontal stationary lines can be attached to it. To elevate the line to the desired height, the lower nut is tightened. The top nut must be properly tightened for the hanger to function correctly after the adjustment.
- Split Pipe Ring with a Turnbuckle Adjustment
A pipe attachment that allows installation before or after the pipe is in place and is advised for suspension of non-insulated horizontal stationary lines. Additionally, it offers a cost-effective structure and the utilization of globally adaptable components.
- Steel Turnbuckle
A device with internal threads on both ends is a turnbuckle. It serves as a vertical adjustment while joining two threaded rods.
- Steel Clevis
A piece of equipment that joins a threaded rod to a bolted or pinned connector on the other side. Installations for high-temperature piping typically use steel clevis.
- Adjustable Roller Hanger
Used to suspend horizontal lines where an axial moment will arise owing to expansion and contraction, piping support is hung from a single rod.
- Spring Sway Braces
A spring sway brace is a piping support device that is advised for use in guiding or restricting pipe movement resulting from thermal expansion and regulating vibration, and bracing a pipeline against sway. They are made up of springs that can function in both compression and tension to produce a restraining force.
- Variable Spring Hanger
The variable spring hanger is a device with a single spring coil that supports the gravity loads of pipelines subjected to vertical thermal movements. This spring hanger creates a varying load when the channel moves from cold to hot places. This spring hanger supports the pipe from above.
- Variable Spring Trapeze Hanger
The variable spring hanger is a device with a single spring coil that supports the gravity loads of pipelines subjected to vertical thermal movements. This spring-loaded hook creates a variable load as the channel moves from the cold to the hot position. This spring hook holds the tube from above.
- Constant Support Hanger, Horizontal Type
A continuous support hanger supports the gravity loads of pipelines subjected to vertical thermal displacements using a single spring coil in conjunction with counterbalancing systems. When the pipe switches from the cold to the hot position, this piping support creates a steady load. The spring coil is horizontal in the horizontal type constant hanger support, which supports the pipe from above.
- Constant Support Hanger, Vertical Type
The pipe is supported from above by the vertically positioned spring coil in the vertical type constant hanger support.
Typical Pipe Support Brackets
- Light Welded Steel Bracket
The light-welded steel bracket is a braced cantilever device that works with rod-type hangers to sustain a gravity load. The brace on this device can be positioned above or below the horizontal member and can be attached to a wall.
- Medium Welded Steel Bracket
The medium welded steel bracket is a braced cantilever device that can withstand horizontal loads up to 6670 N and maximum gravity loads. The main member and the loads can be applied anywhere.
- Heavy Welded Steel Bracket
The heavy welded steel bracket is a braced cantilever device to withstand maximum gravity and horizontal loads up to 13,340 N. The loads may be placed anywhere along the main part.
- Side Beam Bracket
Without any welding, this device is simply bolted to the member and offers a method for vertical adjustment. It is intended to be mounted to the sides of steel or wooden members.
Typical Pipe Saddle Supports
- Pipe Saddle Support
A pipe saddle is a supporting structure with a curved base that cradles horizontal lines by transferring forces or loads to the facility next to it.
- Pipe Stanchion Saddle
A pipe stanchion saddle supports cradling horizontal lines where vertical adjustment is required. The U-bolt yoke attached to this support provides stability in the piping system.
- Adjustable Saddle Support
The pipe saddle support is identical to this device but with an additional adjustment facility.
- Pipe-covering Protection Saddle
A tool created for use on horizontal, insulated, high-temperature lines where heat losses must be minimized and insulation must be protected from harm.
