In this paragraph, I am going to explain about alignment guides. Firstly they are designed to be installed next to expansion joints. Secondly they are made of steel pipe and copper tube that runs to maintain the center-line of the pipe/tube. Next alignment guides expansion joints are large-structure. Furthermore low-mass technology resulting in minimum weight while providing 3-Dimensional alignment using the conservative Spider & Cylinder arrangement.
Moreover, pipe or copper tube systems that incorporate expansion joints, ball joints, or loops to absorb expansion must include three additional major elements. Main and/or intermediate anchors, supports, and alignment guides.
Requirements follow the Standards of the EJMA, Inc. Do not include internal guides require an alignment guide to be located 4 diameters from the face of the expansion joint. Expansion joints additional guide 14 diameters from the first guide. Expansion joints with internal guides require only one alignment guide to be located 10-14 diameters from the expansion joint.
The maximum alignment guide spacing in the intermediate portion of the run is a function of the pipe/tube properties (modulus of elasticity and moment of inertia) the design pressure, and the expansion joint effective area and spring force. Contact Us for a quote or more information.
Steel Pipe Guides
Alignment Guides manufactures and inventories standard for nominal pipe size (NPS) steel pipe from 3/4” through 14” with varying insulation thickness. Hot dipped galvanizing or all stainless steel construction are also available. In tight spaces, rotated housings are available. The maximum operating temperature is 500°F. All stainless steel construction is also available to provide greater corrosion resistance, higher temperatures, or cryogenic systems.
Copper Tube Guides
Alignment Guides manufactures and inventories standard for standard size copper tube from 3/4” through 4” with varying insulation thickness. Hot dipped galvanizing is available as an option. In tight spaces, rotated housings are available. The maximum operating temperature is 400°F. All stainless steel construction is also available to provide greater corrosion resistance.
Product Selection (Part Number) & Ordering Instructions:
- Choose Steel Pipe or Copper Tube, then locate correct Table.
- Select the size.
- Select insulation clearance: a maximum value equal to or greater than the insulation thickness to be installed.
- Verify the Alignment Guide Expansion/Travel stated is equal or greater than the motion occurring at the guide location. For additional expansion increase the last part number indicator as needed.
- For Hot dipped galvanized steel or stainless steel materials, select one of these options below in the example.
- Confirm the guide housing “A” spacing will fit into the system. If it does not, select the “-45” degree housing and spider option and re-verify the spacing.
