Saddle coverings are used with insulated pipes in order to provide protection to the insulation at points of support. Roller stands, elbow supports, and other items can be supplied in adjustable models which allow field crews to make easy installations.

There is 3″ ofadjustment permitted for a turnbuckle.
Roller hangers are used for the suspension of pipe from a single rod where horizontal movement may occur because of expansion or contraction.
Steel washer plates are components used on top of channels or angles to support pipe with rods or U-bolts.
A bearing plate is also referred to as a slide plate. It is a component that can be fabricated from a variety of materials including graphite, PTFE, 25% glass filled, stainless steel, and bronzphite. The purpose of slide plates is to produce a low-coefficient of friction between a stationary support element and the moving pipe support component to reduce the forces generated as a result of pipe deflections during operation.
Yes, u-bolts can beused on insulated steam lines.
All pipe support components are fabricated with a minimum factor of safety of 2.5.
At 650˚F, the clamp material is approaching its maximum temperature rating so we would recommend an alloy material above that temperature.
For offshore we have topaint the rollers or coat them in neoprene to withstand the harsh environment.
The roller support isdesigned to be used with rigid insulation and must be sized according to theouter diameter of the insulation.
The Figure83 clevis hangers support vertical pipe, so they do not resist lateral or axial movement, but support the vertical piping and resist vertical movement of the pipe.
Clevis Hanger
The adjustment for a clevis hanger is obtained by the threaded rod connection and the upper section of the clevis hanger. The space between the pipe’s outer surface and the top section of the clevis hanger can be utilized to adjust the overall elevation of the hanger assembly.
Galvanized Clevis Hanger
In general, hanger supports, be they rigid rod hangers, variable spring hangers or constant spring hangers, all use threaded connections between our existing structural steel component and our pipe attachment point. These threaded components are used to meet both our elevation difference and to provide some adjustment per actual site conditions. The threaded components could consist of all threaded rods, eye rods, clevises, turnbuckles, etc.
A lug plate is a component that is welded to existing structural steel members and allows another pipe support component to be pinned at that location.
Shear lugs are primarily required whenever a clamping support is being loaded in the axial direction of the pipe. It should be noted that we are not relying upon the clamping force of the support to withstand the axial load, but we are relying on the shear lugs and the clamping contact to absorb the axial load.
In order to ensure full load carrying capacity (safety) of a specific size turnbuckle, one must provide full thread engagement at both ends of the turnbuckle. In other words you should see part of the left hand rod and the right hand rod protruding into the open section of the turnbuckle.
In order to join a steel washer to a steel rod, you must utilize a nut in combination with a steel washer and threaded rod component to distribute the load at the nut surface to the washer surface.
Rollers are generally utilized when axial movement at the supportlocation would generate swing angles in excess of 4 degrees on hanger typesupports or when movement is greater than approximately an inch on base typesupports.
