Blasch ceramic ferrules provide more effective waste heat boiler tube protection and allow for much greater design flexibility than traditional refractory systems. This is accomplished through the separation of the structural and insulating functions of the ferrules.
There are several options available, depending on the specific details of your particular equipment. Operational advantages of our precast ferrule systems include:
At the 2017 Brimstone Vail Conference, Clinton Schulz of CITGO Refining and Chemicals presented results that his plant has realized utilizing a patented ferrule design which was engineered in cooperation with Blasch in 2005.
Download his full paper to find out how patented modifications to the Blasch Ferrule design have resulted in longer boiler tube life due to reduced peak heat flux.
Before: Turbulence due to eddy effects dramatically increases heat flux
After: Patented modifications to the Blasch Ferrule design result in longer boiler tube life due to reduced peak heat flux

Patented Blasch boiler tube ferrules are pre-engineered for each and every boiler tube installation. Customers can expect to receive ferrules that are properly sized, accurately molded, and completely wrapped with all required fiber insulation.
Installation is as simple as taking them out of the box and slipping them into the boiler tubes. Castable refractory is not necessary between the ceramic ferrules and only the most minimal amount is required around the periphery. Operators can save days on turnaround without the need to painstakingly install, and then cure out, large expanses of castable refractory.
Our patent-pending ProLok™ twist and lock two-piece ceramic ferrules have several advantages over traditional one-piece systems and offer increased reliability over traditional two-piece ferrules.
Other precast boiler tube ferrules are designed to be installed with some amount of protective barrier consisting of mortar between the ferrules which creates a problem when ferrules heat up and expand. The mortar is crushed during this expansion and can fall out after repeated cycles, leaving a direct path to the tubesheet. Blasch ceramic ferrules for boilers are engineered to come to closure at operating temperature without the need for this secondary protective barrier.
In this presentation, learn about waste heat boilers, their applications, and what Blasch has to offer that can potentially be both a solution and improvement to your current process. With our shape making capability and 30+ years in the industry, we can help you engineer a ferrule solution to your specific needs.
Blasch’s ProLokTM ferrules have a cast in place twist & lock bayonet feature. This short video demonstrates how to easily rotate and lock the stem into place so it can’t back out.
In this short video, learn how fast and easy it is to install Blasch’s ProLok Two Piece Ceramic Ferrules into a waste heat boiler, potentially saving you days in a turnaround.
Originally designed to be a simple, stable wall replacement for the stacked cylinders, the Blasch HexWallTM was upgraded to provide mixing enhancement and the same functionality as a series of solid baffle walls. Download this white paper to learn more about the process benefits that your plant can experience, including:
– enhanced mixing
– improved destruction efficiency of unwanted compounds
– increased residence time
– protection of the tubesheet from radiant heat or hot spots
Download this case study to learn how the installation of MECS© HexPro Ferrules, manufactured by Blasch Precision Ceramics allowed the IPL Mount Isa sulphuric acid plant to experience:
– 67 % faster installation time of HexPro ferrules
– the absence of refractory mitigates other adverse effects
– lower pressure drop, longer service life, and reduced maintenance costs
