¾" TO 2"
There is a strong demand for stainless expansion joints in 2” thru 16” diameter with 2” axial and 1/4” transverse capability. Weld ends are most common, but there are also flanged requirements. All our flanged joints have one floating flange to facilitate installation and eliminate torsional stress. The other is raised face.
Like many companies, not only were our deliveries extended, but whenever an inquiry came in, we would redesign and re-cost needlessly. We decided the thing to do was stock all sizes 2” through 16”, as shown in our dimension tables.
There seems to be some confusion as to what 2” travel means, so let’s go over it. Every expansion joint has its neutral length. From this neutral position, the joint can be used for a full 2” compression or 2” expansion, but never a combination of the two. They are perfectly suitable for 1” compression and 1” extension or as a further example, 1 1/2” compression and 1/2” extension. In other words, in its working life, total movement should never exceed combined 2”.
