Founded in 1979, Blasch Precision Ceramics is an advanced refractories company specializing in the design, manufacture, and marketing of close tolerance, complex net shapes and refractory components.

Blasch takes an engineering problem solving approach to Improving Refractory Performance. by utilizing a proprietary Injection molding process. This process allows for almost complete freedom of design yields components exhibiting exceptional Thermal Shock resistance provides remarkable consistency, in terms of physical properties as well as dimensional tolerances.

Blasch developed the precast hexagonal and square head Ferrule Systems to address cracking in large tubesheets utilizing the traditional round ferrule and castable approach. Believing that the key to refractory success is thermal expansion management, Blasch designed a system that utilized individual precast ferrules that are carefully sized to allow for repeated thermal cycling without the buildup of stresses that one would find in a monolithic castable or mortared ferrule system. The ability to limit the transmission of thermal stresses across large sections of tubesheet allow for operation with much greater confidence of very large and very high temperature units, particularly those that see repeated cycling. These precast ferrules are used in applications such as Claus Sulfur Recovery Units, Sulfuric Acid Plants, reformers, and incinerators in various services. Blasch ProLok Ferrules were developed to address inconsistent tubesheets, thermal stressing and failure from 1 or 2 piece configurations where the stem of the ferrule either was cracking or was walking out the tubesheet; a phenomenon where the boiler tube and welds are exposed to the process gas stream.

The Blasch HexWall Checkerwall was designed to address the need of a precast refractory checkerwall that was mechanically stable over the long run in a variety of sizes and in even the highest temperatures. In contrast to conventional checkerwall designs, the HexWall Checkerwall consists of a series of hexagonally shaped blocks that are stacked horizontally one atop the other and lock together through the use of a series of tabs and slots to provide considerable mechanical advantage.

The Blasch VectorWall can be configured to create an almost endless series of customized flow fields within reaction furnaces and thermal oxidizers. From a process standpoint, a large portion of the flow jets through the center of a choke ring do not satisfy the minimum residence time for key reactions. Blasch’s VectorWall is specifically designed to address these problems. They have better ammonia and BTEX destruction from higher RF front zone temperatures due to the unique radiation blockage from the Vectortile. Along with increased path lengths and an increase in temperature in Zone 1 (before the wall), there is the potential to not only use less fuel but offer lower CO2 emissions and shorter furnace designs. These precast walls are used in high temperature reaction furnaces located in Claus sulfur recovery units, sulfuric acid plants, thermal oxidizers and incinerators in various services.

Blasch supplies their StaBlox Reformer tunnel system with TOP into Hydrogen Reformers worldwide. In FCCU's Blasch has several precast engineered shapes made in a variety of extremely wear resistant materials. 

Blasch also supplies a number of custom refractory shapes for use anywhere there is elevated temperatures, corrosion or abrasion, such as in in Burners, Pilots, Flares and a wide range of other chemical processes.
