Due to increased requirements for higher levels of thermal efficiency and safety on high temperature industrial piping and equipment, many calsil insulation projects are now being specified with thicknesses greater than the maximum 3″ wall for pipe cover in a single layer. This industry standard ensures the individual sections do not become too heavy for an installer to handle on the job site. Installing in 2 and 3 layers with both horizontal and circumferential joints staggered is becoming the norm, not the exception to the rule. Multi-layering should be considered a best practice to ensure as the hot metal pipe grows in length and to a lesser extent diameter, that joints between the insulation sections do not open up.
Many of our customers have asked us to create a reference tool that allows them to quickly build multiple layer configurations. We listened and are happy to share this new tool with the market. TPSX-12 is produced in accordance with ASTM C533 type I for physical properties AND ASTM C585 for pipe sizes and dimensional tolerances. This sizing specification allows for the “nesting” of congruent sizes in order to provide total thicknesses greater than 3″.
Please note this chart demonstrates just ONE possible way to build multi-layer assemblies. Due to our unprecedented assortment of pipe sizes and wall thicknesses, there are many other permutations to achieve the same result based on what sizes are in stock at any particular time and location. TPSX-12 is available in 1, 1.5, 2, 2.5 and 3″ wall thicknesses for ALL pipe sizes from 3/8″ iron up to 126″ diameter.
