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).
A rod threaded its full length.
A pipe support used to restrict the pipe movement at a particular location.
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
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.
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.
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.
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.
Round steel bar normally threaded used to connect other components, to make up a Pipe Hanger Assembly.
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.
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.
A scale attached to a Variable Spring Hanger to provide a means of indicating the supported load.
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.
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.
Any device used to connect the pipe to the remainder of the Pipe Hanger Assembly.
A bolted Pipe Attachment which clamps around the pipe to connect the pipe to the remainder of a Pipe Hanger Assembly.
A Pipe Attachment used to hold the pipe directly to a structure, also referred to as a strap or pipe strap.
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.
An assembly used to uphold a piping system at desired location.
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.
A device by which piping is carried from beneath and is used to carry the piping weight in compression.
A Pipe Hanger which does not permit vertical movement.
A Pipe Support which does not permit vertical movement.
Any vertical portion of a piping system.
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.
