Frequently Asked Questions

General FAQs

I am interested in ordering some welded pipe sleeve assemblies for my job. Can Portland Bolt design some welded pipe assemblies per my application?

Unfortunately, Portland Bolt does not employ engineers and due to liability issues, we are not in a position to make recommendations with regard to size, grade, or the design of anchor bolts for specific applications. Welded pipe sleeve anchor bolt assemblies are job specific and are designed and detailed by an engineer for a specific purpose. Portland Bolt can manufacture the assembly per a project’s drawings and specifications, once they have been engineered.

The anchor bolts that I am installing are going to be used in a high temperature environment. Is it advisable to use a plastic anchor sleeve for this application?

No. Both Contec and Wilson warn against use of plastic sleeves with high temperature environments, like an oven. Conversely, extreme low temperatures could be problematic as well. See the technical specifications for Vicat Softening Point and the Brittleness Temperature for both Wilson and Contec anchor sleeves.

What are the differences between Contec Anchor Bolt Sleeves and Wilson Anchor Sleeves?

Wilson vs Contec sleeveWilson Anchor Sleeves are used with one diameter of anchor bolt and all sizes are colored black. Contec Anchor Bolt Sleeves are used with at least two different diameters of anchor bolts and in some cases three. Each size of Contec anchor sleeve is easily identifiable by different colors for each size. Contec Anchor Bolt Sleeves often must be cut on each end in order to be used with the diameter of anchor bolt being set into concrete. Other than color difference and the fact that Contec sleeves can be used with multiple diameters of bolts, there are virtually no differences between the two sleeve brands. See this FAQ for more information.

Are certifications available for plastic anchor sleeves?

No. Chemical and strength documentation are not available for the high-density polyethylene that anchor sleeves are made from.

The large job I am working on has huge anchor bolts and lots of them. I will need many large plastic anchor bolt sleeves for use with my anchor bolts. Are these items stock?

Large quantities of large plastic anchor sleeves in general may need to be special ordered and may have a longer lead time associated with them. This is especially true for plastic anchor bolt sleeves for use with anchor bolts roughly 2-1/4” in diameter and up. Custom plastic anchor sleeves can also be made given enough time, depending the the brand of sleeve.  Often, it is easiest to use a larger or different plastic sleeve size with an anchor bolt if a different sleeve size is required.  Portland Bolt does stock a comprehensive line of sleeves through 3” diameter, so feel free to contact Kyle and he will be happy to check inventory for you.

I need some plastic anchor sleeves in a hurry. Are there any issues with shipping some Wilson Anchor Sleeves or Contec Anchor Bolts Sleeves to me via air freight?

Although plastic anchor bolt sleeves are extremely light they are even more extremely voluminous. The space they take up is so great that shipping companies will price the shipping cost not by the actual weight, but instead by the dimensional weight of the space taken up by the sleeves. This dimensional weight can be so large that air shipping large amounts of sleeves can be highly prohibitive.

Are metric-sized plastic anchor sleeves available?

No. All of the anchor sleeves that are commonly available in the United States are sized for imperial dimensioned fasteners. An easy solution is to soft convert the metric size desired to the closest imperial size available and cut away material on the anchor sleeve using a knife. Often imperial and metric diameter material is very close in size, if not identical.
