Does an anchor restrict motion in all direction that is X-Y-Z directions?
Anchors will restrict movement in all directions and will also restrictthe rotation of the pipe as well. In the stress analysis, we may see loads inall three directions which will tell us how “strong” the anchordevice has to be.

Can you use insulated piping on pipe rollers? Would the insulation be crushed?
In order to use pipe rollers in this application, an insulated pipe support has to manufacture as part of the roller assembly. We use a higher density insulation so that the insulation will not be crushed – 10 lb. 14 lb. 20 lb. or 32 lb. depending on the load.
Do you have rules of thumb for selecting insulation thickness?
The thickness of the insulation is based on the amount of heattransfer that you would like to reduce.

How would you support a sloped line with a Type F variable spring?
If you have a sloped pipe shoe on the line, the bottom of the shoe must be parallel with the spring to support the load. You can slope the shoe where it comes in contact with the pipe.

What is a hot shoe?
A hot shoe is name that refers to insulatedsupports which cradle the pipe and are intended for operation at high temperaturesexceeding 200 degrees Fahrenheit.

How do you bond FRP pads to the pipe?
The area where the pad is to be affixed on the pipe and the inside surface of the wear pad must both be sanded first in order to create a rough surface for installation. Then an epoxy adhesive is generously applied to the inside surface of the wear pad. Make sure that the pipe surface is clean and free of all environmental debris and affix the wear pad to the pipe. Finally, add an additional amount of glue around the edges of the wear pad and apply temporary straps around the pipe and pad to tighten the contact between the pad and pipe while it is drying.
You can see instructions below:
Preparing the FRP pad for Installation
What are FRP wear pads used for?
FRP wear pads are used as corrosion protection on uninsulated pipes and can be secured to FRP pipes to provide an extra layer of pipe and thereby extend the life of the pipe. FRP wear pads also eliminate metal to metal contact between the pipe and its metal supporting structure.
FRP Wear Pads
What type of FRP products do you fabricate?
At Piping Technology, we fabricate both FRP wear pads to be used on metallic and non-metallic pipe. We also design and fabricate pipe supports such as saddles and clamps that will be installed on FRP piping systems.

What can I use to avoid metal to metal contact of a pipe clamp on carbon steel pipe?
We recommend that you use a non-metallic wear pad or FRP pad that is fabricated from fiberglass reinforced plastic and is secured to the pipe using an epoxy adhesive. Another option is the use of a neoprene lining on the clamp which also prevents metal to metal contact.
See Figure 182 in our Online Catalog.

What is a gusset in a cold shoe?
Gussets are added reinforcement plates used to strengthen the overall structure of the shoe and provide either extra load carrying capacity or added strength when the pipe shoe is used as a guide or anchor.

How do I service high temperature supports for pipes?
Most high temperature supports (i.e. hot shoes) do not require any type of service or maintenance. If a shoe is damaged, it would need to be completely removed from service and refurbished.
How do you support stainless steel pipe shoes?
Stainless steel pipe shoes, like others of similar construction but different materials, would be supported by the available surrounding structural steel elements in the piping system.
How do pipe supports for cold insulated lines differ from those for hot insulated lines?
The primary difference between insulated supports for cold temperatures and hot temperatures lies within the insulation materials themselves.Cold supports typically utilize polyurethane foam as an insulating material, and hot pipe supports typically use combinations of calcium silicate and marinate materials.

How are pipe shoes connected to a beam?
Pipe shoes are connected to a beam depending on their function whether or not they are a support, guide or anchor. In the case of a support, the shoe would rest on top of the supporting steel structure. In the case of a guide, in most instances the secondary supporting base plate/guide combination would be welded to the supporting structure and the shoe would rest upon the base. In the case of anchor supports, in most instances, the base of the shoe is welded directly to the supporting steel.

How do you inspect pipe shoes?
For welded design pipe shoes, you should ensure that there is no severe corrosion, no damage to the shoe plate components and that the welds are all intact.
For bolted pipe shoes, you should ensure that is no severe corrosion, no damage to the shoe plate components, ensure that all bolts are intact and all components are tightened to the correct torque specifications.
For insulated supports, you should ensure that there is no severe corrosion, no damage to the shoe plate components, all bolts are intact and properly tightened, and insulation is complete, not damaged, or exposed to the environment.

Where do you place adjustable supports in piping systems?
In general, most adjustable pipe supports are designed to compensate for anydiscrepancies between the design specifications and actual site conditions. Additionally,they can be used for situations where only rough estimates are availableregarding the orientation of the pipe with surrounding elements.

How can I anchor pre-insulated piping for cryogenic systems?
One method would be to utilize an injection molded anchor whereinsections of the pipe spool are built in to the support assembly and theinsulation will be poured around that pipe spool section to fill the voidsbetween the anchor outer shell and integral lugs which essentially lock thepipe spool and outer shell together.

How do I attach an anchor to a pipe without welding?
In instances wherewelding to the pipe would be prohibited, anchor systems can be designed whereinsufficient tension can be developed between the clamp surface and the pipe torestrain or anchor the pipe in position. Supplementary pipe hardware such asdisc springs can be incorporated into the overall design to ensure that thetension remains constant throughout the operating cycle of the pipe system.

How do I attach pipe shields over insulation?
In the majority of instances, pipe shields are held in place over theinsulation using thin gauge stainless steel straps and band locks. We generallyuse a minimum of two straps.
