Why is a clamp support used in cold lines?
Added on Tue, Nov 2, 2010
Insulated clamp supports may be used in cold applications where the insulation and clamp combination act together to provide a load carrying member and simultaneously provide insulation for the pipe. In some applications, the clamp would be fixed... Read More
What clamps do I use to hold two pipes together?
Added on Fri, Feb 11, 2011
None of the clamps manufactured by Piping Technology are designed for holding two sections of pipes together. Read More
What is a pipe clamp?
Added on Tue, Feb 1, 2011
A pipe clamp is a pipe attachment which clamps around the pipe to connect the pipe to the remainder of a pipe hanger assembly. Pipe clamps are recommended for the suspension of cold pipe lines and may or may not be insulated. 3-Piece Pipe... Read More
What is a riser clamp?
Added on Tue, Feb 1, 2011
A riser clamp is a pipe clamp for the support of vertical pipelines, and they include separate load bolts, to transfer the piping load to the remainder of the pipe hanger assembly. Read More
What are cradle clamps?
Added on Fri, Feb 11, 2011
A cradle clamp support refers to a shoe type support which you do not weld directly to the pipe but rather use a bolted configuration instead of a welded configuration. Cradle Supports Read More
How resistant to movement are pipe clamps?
Added on Wed, Mar 23, 2011
When using pipe clamps as part of an anchoring assembly, the resistance to the pipe movement can be developed in two fashions. One way would be to apply sufficient bolt torque to the pipe clamps which produces a friction load which is adequate to... Read More
What is a pipe cradle?
Added on Fri, Feb 11, 2011
A pipe cradle is a base mounted support with its contours that match the diameter of the supported pipe so that it can be welded directly in place. U-bolt Cradle Support with Neoprene Liner Read More
How do you use riser clamps?
Added on Thu, Jun 16, 2011
Riser clamps are a two point load bearing component and are usually used for vertical running pipe lines wherein shear lugs are welded to the pipe, the riser clamp top surface contacts the shear lug, and the load is transferred through the legs of... Read More
Why are pipe clamps on a horizontal pipe assembled with 45° bolting holes direction?
Added on Thu, Nov 10, 2011
Pipe clamps are assembled that way so that adjacent pipes can be placed closer together. Three-Bolt Pipe Clamp and Riser Clamps Capable of Supporting both Horizontal and Vertical Piping Read More
Is the use of pipe clamps recommended for vibrating piping systems?
Added on Thu, Nov 10, 2011
You can use them if the pipe clamps are lined with neoprene or Fabreeka® or any other vibration dampening pad. Three-Bolt Pipe Clamp Read More
Are the loads on customized units stamped on the clamp?
Added on Thu, Nov 3, 2011
No, they are not provided with the load on the clamp. We recommend you keep a log book in order to keep track of the supports within your piping system, along with their loads and movements. Custom Designed Pipe Clamp-Guides Read More
Can clamps with a galvanized surface be welded to a steel structure (for support purpose) or the surface needs to be ground prior to welding?
Added on Thu, Nov 10, 2011
The pipe clamps with a galvanized surface has to be ground back to avoid releasing toxic fumes. Riser Clamp with Hot-Dipped Galvanized Finish Read More
What is the major benefit or reason for using a yoke pipe clamp as opposed to regular two bolt pipe clamp?
Added on Thu, Oct 27, 2011
The main benefit is that the yoke clamp can support a greater amount of load. Additionally, the lower portion of the clamp does not significantly protrude beyond the pipe O.D. This is beneficial in installations where clearance is an issue. Yoke U... Read More
Clamp with insulation may be the source of water ingress, which may lead to corrosion. How do you tackle that situation?
Added on Thu, Nov 3, 2011
One method of reducing the corrosion between our pipe surface and our clamp surface is to use neoprene lining that does not absorb water. Neoprene Lined Pipe Clamp Read More
If we can exceed the pipe hoops stress when using clamps, how do we prevent the field guys from damaging the pipe?
Added on Wed, Nov 23, 2011
You can provide them with clamp torque values on the bolts of the clamp so as not to exceed the hoop stress of the pipe. 3-Bolt Pipe Clamp Installed in the Field Read More
Why are the "wings" so long on the riser clamp?
Added on Fri, Nov 25, 2011
The "wings" on a riser clamp allows for lateral movement and steadying of pipe risers and also the wing length is a function of the available attachment to our existing structural steel. Riser Clamp Read More
What is your temperature limit for HDG carbon steel clamps?
Added on Thu, Nov 10, 2011
Our max temperature on HDG (hot dipped galvanized) carbon steel clamps we recommend is up to 750 degrees F. If you have an application that requires a higher temperature, we recommend you go with our 70A, our Alloy Light Three-Bolt clamp. Hot... Read More
When should I use a Yoke clamp instead of a bolted clamp?
Added on Wed, Nov 23, 2011
Yoke clamps have higher allowable loads than a bolted clamp. Secondarily, yoke style clamps are effective in areas where the bottom part of the pipe is in close proximity to structural steel or other pipe components. Snubbers with Yoke... Read More
We are using plastic composite piping especially offshore due to corrosion like glass reinforced piping. How do the clamps differ for these materials instead of steel or stainless?
Added on Wed, Nov 23, 2011
The clamps do not need to support as heavy of a load in this case. The outer diameter of the piping should be the same as the steel piping. 3 Bolt Carbon Steel Pipe Clamps Read More
What is the axial restraint between the foam insulation and a pipe clamp?
Added on Fri, Nov 25, 2011
Axial restraint is usually the clamping force and in case axial load is considerably higher, axial stops are welded to the inside of the clamp to prevent axial movement of the insulation within the support. Cold Insulated Pipe Anchors with Axial... Read More
Do the Bolts require a certain Torque level? If so how is this accomplished?
Added on Fri, Nov 25, 2011
On some clamps, a certain torque level is required. It really depends on the application. The torque levels can be found in the MSS standards which we utilize for pipe support design. Read More
In clamps that operate at higher temperatures, how do you specify the bolting torque?
Added on Wed, Nov 23, 2011
For high temperature clamps, we recommend the use of spring washers in order to prevent bolt relaxation. Variable Spring with a High Temperature 3-Bolt Clamp Read More
When should I use a clevis instead of a clamp?
Added on Wed, Nov 23, 2011
Use the clevis when you do not need the clamp to be held in place during the movement. PTP- 8 Type C Variable Spring Assemblies with a Rod, Clevis, and Hex Nuts Read More |
