Insulation for Power Plants

No matter the type of power plant – coal, natural gas, nuclear – Johns Manville Industrial offers the breadth of insulation solutions that are necessary to meet the wide variety application needs that are unique to power plants.

We offer durable, high-temperature insulations, like calcium silicate, that couple high-temperature insulation with resilient compressive-strength and the best corrosion inhibiting performance in the industry. Our product line also includes hydrophobic blankets, mineral wool pipe and block insulations, and a non-combustible fire-protection line. Our insulations help create the safest environments possible while improving process control, addressing CUI, and reducing energy loss and greenhouse gas emissions.

Water-repellent mineral wool pipe insulation with adhesive coated v-grooves – ships flat, formed on site (Service Temp: up to 1200°F)

Water-repellent MinWool-1200® Field-Formed pipe insulation is a factory "v-grooved" mineral wool board with a unique pressure-sensitive contact adhesive in the grooves. It ships in flat 4-mil plastic and is easily formed on the job site. All mineral wool insulation is made from basalt, a volcanic rock, and bound with a thermosetting resin. Advanced manufacturing technology ensures that our mineral wool products have consistent product quality, with high fiber-density and low shot-content, for excellent performance in thermal control and fire resistance applications. Minwool-1200 Field-Formed pipe is manufactured to specific pipe sizes with a variety of facing options.

Water resistant, type I calcium silicate insulation with XOX Corrosion Inhibitor® (Service Temp: up to 1200°F)

Thermo-1200® is a high temperature, water resistant* Type I calcium silicate designed to inhibit water absorption. In the event of a typical rainstorm  water will bead on the surface of the insulation without penetrating into the substrate. This will allow contractors some additional time to install the insulation without immediately applying the jacketing afterward, offering more time and flexibility in the installation process than has traditionally been available. Additionally, Thermo-1200 contains XOX Corrosion Inhibitor®, a proprietary corrosion inhibiting formula that helps inhibit corrosion under insulation (CUI).

 

Thermo-1200 is available in pipe, block, and curved segments. It is inorganic, non-combustible, asbestos-free, and it meets or exceeds the physical and thermal property requirements of ASTM C533, Type 1. It can be used in systems with operating temperatures that range from ambient up to 1200°F (650°C).
