ICA Mineral Wool 1200°

ICA M.W. 1200° Hi-Temp Pipe Insulators - ASBESTOS FREE!

Dual-Temperature, Premolded, Top Quality, Two-Pieced Thermal-Acoustical Pipe Fitting Insulators


The ICA M.W. 1200° is a unique product in the realm of high-temperature preformed insulation for pipe fitting areas.

The ICA M.W. 1200° pipe fitting insulator is serviceable to 1200°F and was designed to be utilized in conjunction with any high temperature straight-run insulation of equal surface temperature capabilities. ICA M.W. 1200° pipe fitting insulators have been employed successfully in mineral wool, calcium silicate, and expanded perlite systems.

ICA's molding process yields a fitting insulator which is completely different from the routed fitting insulators which have been extensively marketed in the past. In a routed insulator the finished product is cut from a section of block insulation with comprising fibers being oriented in a single direction, hence, extreme fragility in the finished product.

In contrast, the ICA product is molded under extreme heat and pressure from uncured green felt which is impregnated with a thermo-setting resin. Thus the ICA M.W. 1200° fitting insulator is composed of fibers that are interbonded and intermeshed in many different directions; the resulting strength means that the ICA insulation cover can be and is produced in fitting sizes never before realized.

Unlike a routed insulator, the ICA fitting insulator will not readily delaminate. When coating of the fitting's exterior surface is desired or required, fibers will not dust or fuzz up. This remarkably durable insulator exhibits superior load-bearing characteristics when compared to previous applications, for fitting areas. Extensive on-the-job loss due to breakage is a thing of the past.The ICA M.W. 1200° is actually strong enough to be utilized on line, removed for inspection or maintenance purposes. and utilized once again.

ICA M.W. 1200° pipe fitting insulator are molded in two half sections, matching the density and thickness standards of the adjoining pipe covering. All fitting insulators are currently manufactured in weld, screwed, socket, and copper tubing types; all in 90° and 45° and tee configurations. For pipe sized presently unavailable and for further speciality application requirements, consult with ICA's Research and Development Department regarding our design and engineering capabilities.

Since the ICA M.W. 1200° is not a mitered or segmented unit, there are no cracks or voids to fill on the exterior surface. The fitting insulators are simply and quickly applied by placing two premolded matching half sections over the pipe fitting and joining them together using tape, wire or adhesive.

Benefits of using pre-formed ICA M.W. 1200° High temperature fitting covers:

  • Two-piece, pre-formed design minimizes guess work in estimates of labor and fitting costs.
  • Where necessary, fitting insulators can be removed, the testing completed, and the same covered wired back on the system intact.
  • Superior tensil strength and load bearing qualities.
  • Excellent K factor. Mineral wool has always been a known performer in regards to thermal efficiency.
  • Unabrasive surface area that is easy to handle and install in the field - resulting in fast, economical application.
  • Eliminates costly blanket wrapping or mitering.
  • Composite system provides a natural expansion joint. Allows damage free expansion/contraction/deflection in fittings and covering.
  • All interior surfaces are stamped with the ICA "H" and the proper pipe and thickness size for quick field indentification.
