The Anchorage Group has created an A-Z Guide of Terminology used in the pipeline and pipe support system industry.
Having adjustment capability (usually with threads).
- Threaded Rod:
A rod threaded its full length.
A pipe support used to restrict the pipe movement at a particular location.
- Beam Clamp:
A type of forged or fabricated clamp that is used to attach rod hangers to beams by clamping onto the load flange.
The bottom component of a pipe support to uphold the piping system.
Cantilevered member, with or without a knee brace, designed to withstand a gravity load as well as horizontal forces.
The piping support assembly clamped together using bolts
- Clevis Hanger:
A Pipe Attachment providing vertical adjustment, consisting of a clevis type top bolted to a formed steel bottom strap.
A state of materials at very low temperatures (below -150ºC)
- Cryogenic Pipe Support:
(Also known as cold shoe) A type of assembly used to give necessary support to a piping system while not dissipating cryogenic temperatures of the piping system at a certain point.
Any of a range of devices which are used to make up a Pipe Support Assembly.
- Constant Support Hanger:
A mechanical and spring coil device which produces a relatively constant supporting effect, while permitting vertical pipe movement.
- Eye Rod:
A Hanger Rod having an end formed in a circular or pear shape, permitting attachment to other components by means of a bolt or pin. The eye may be forged, welded or non-welded.
- Eye Socket:
A device which provides for the attachment of a threaded Hanger Rod to the bolt of another component.
A process in which material is cut to certain size and moulded into different required shapes.
- Forged Clevis:
A device which provides for the attachment of a threaded Hanger rod to a bolted or pinned connection.
A device used to permit pipe movement in a predetermined direction while restraining movement in other directions.
A type of pipe support consisting of a clamp in which the piping system is upheld from an upper portion rather than from the base. This type of pipe support is available with or without insulation.
- Hanger Rod:
Round steel bar normally threaded used to connect other components, to make up a Pipe Hanger Assembly.
- Heavy Bracket:
A Bracket used for the support of heavy loads.
- Hot Dip Galvanizing:
A process of protecting metallic surfaces from corrosion or rust by dipping the materials for a certain period in boiling chemicals.
- Hot Shoe:
A type of assembly used to give necessary support to a piping system while not dissipating elevated temperatures of the piping system at a certain point.
- Load Scale:
A scale attached to a Variable Spring Hanger to provide a means of indicating the supported load.
- Load Variation:
A term associated with Variable Spring Hangers used to describe the difference in supporting effect between the hot and cold elevations of the support point.
- Mark Number:
A unique number used to identify pipe hangers.
A relative displacement between the Structural Attachment and Pipe Attachment, which may be incorporated into the design of the Pipe Hanger Assembly to accommodate the piping movement.
- Pipe Attachment:
Any device used to connect the pipe to the remainder of the Pipe Hanger Assembly.
- Pipe Clamp:
A bolted Pipe Attachment which clamps around the pipe to connect the pipe to the remainder of a Pipe Hanger Assembly.
- Pipe Clip:
A Pipe Attachment used to hold the pipe directly to a structure, also referred to as a strap or pipe strap.
- Pipe Hanger:
A device which is suspended from a structure and is used to carry the piping load in tension.
- Pipe Hanger Assembly:
A general term used to describe a series of assembled components which make up a Pipe Hanger, Pipe Support, Restraint, Anchor, Guide, etc.
- Pipe Support:
An assembly used to uphold a piping system at desired location.
- Pipe Roller:
A roller device used to support horizontal piping and provide for axial movement.
- Pipe Saddle Supports:
A Stanchion utilizing a curved section for cradling the pipe.
- Pipe Shoe:
A device by which piping is carried from beneath and is used to carry the piping weight in compression.
- Rigid Hanger:
A Pipe Hanger which does not permit vertical movement.
- Rigid Support:
A Pipe Support which does not permit vertical movement.
Any vertical portion of a piping system.
- Riser Clamp:
A Pipe Clamp for the support of vertical piping having separate Load Bolts, to transfer the piping load to the remainder of the Pipe Hanger Assembly.
- Three Bolt Pipe Clamp:
A Pipe Clamp normally used for horizontal insulated piping, which utilizes clamping bolts to attach the clamp to the pipe and a separate Load Bolt to transfer the piping weight to the remainder of the Pipe Hanger Assembly from a point outside the insulation.
A device with one left-hand female threaded end and one right-hand female threaded end, used to join two threaded rods and provide linear adjustment.
A U-shaped rod with threaded ends, that fits around a pipe as well as being attached to a supporting member.
The Load Variation of a Variable Spring Hanger divided by the Hot Load expressed as a percentage.
- Variable Spring Hanger:
A spring coil device which produces a varying supporting effect while permitting vertical pipe movement.
- Welded Beam Attachment:
A u-shaped flat bar device, normally welded to a steel beam used to connect the remainder of a Pipe Hanger Assembly.
- Welded Pipe Attachment:
A Pipe Attachment which requires welding to the pipe in order to connect the pipe to the remainder of the Pipe Hanger Assembly.
- Weldless Eye Nut:
A forged steel device which provides for the attachment of a threaded Hanger Rod to a bolt or pin connection.
