Cast ceramic liners, tubes, seats and shapes for pipes, cyclones, pumps, valves, mills and hot process vessels.
Solids wear out steel where they turn, speed up or hit a wall.
Blasch casts the ceramic part for exactly that spot.
The ceramic wear parts that outlast steel are the ones placed where solids change direction or speed: elbows and reducers in conveying lines, apexes and vortex finders in cyclones, multicyclone tubes, pump liners, valve seats and micronizer liners. Cast in one piece from silicon carbide or dense alumina, they lose wall slowly where steel wears through in months. In a bagasse boiler ash line, a lined elbow has run 30 months with about 10% wear on a spot where steel lasted 3 to 4 months.
Most plants fight wear with the material they already know. It buys time, and the same part fails again at the same place.
Every wear part fails at its weakest point, so the part that lasts is the one designed for the exact place where your current part fails.
Conveying lines fail at the bends and restrictions first. CeraLine lines the whole line with one-piece liners.
One cast liner per section instead of tiles or a coating, for ash, coke, catalyst, slurry and battery materials.
Long and short radius elbows lined around the full bore, where pneumatic conveying wears hardest.
Straight spools up to 7 ft that arrive finished and bolt in during the outage.
Silicon carbide chokes, choke rings and reducers for the narrowest, fastest point of a line.
Sliding abrasion grinds along a wall, as in a pipe bend or a multicyclone tube. Impingement hits a surface head on, as at an impingement block or a cyclone inlet. Both are what silicon carbide and dense alumina are made for.
Ceramic is hard and brittle. Where oversize lumps hit it, the design adds a tougher grade, a metal shell or a polyurethane backing that holds a cracked part in place.
Heat and chemistry decide the grade as much as the particles do. Steam mills and FCC lines need thermal shock resistance, battery and chemical plants need a ceramic the process stream cannot dissolve.
Blasch does not coat or spray. Every part on this page is a cast and fired ceramic component with its own wall thickness.
Three documented cases show the range: an FCCU catalyst line where steel failed within days, a lithium battery plant with a highly corrosive stream, and an iron ore pelletizing plant that switched its multicyclone parts to ceramic.
Separation equipment wears where the flow spins fastest and where the solids leave.
One-piece silicon carbide apexes, cones and cylinders up to 60 inches, with optional polyurethane backing.
Central outlet tubes for calcining cyclones, hydrocyclones and mills, up to several meters across.
Precast shapes for cyclones, diplegs, separators and scrubber venturis in FCC units.
SiClone tubes, spin vanes and outlets that replace cast iron in mechanical collectors.
ALTRON, an alumina bonded silicon carbide, is the grade for fine, hard catalyst in FCC units. InVinCer RB, reaction bonded, carries much of the slurry, pump and lined pipe work.
NITRON, nitride bonded, makes the large shapes for autoclaves and flash vessels. OXYTRON, oxide bonded, handles hot dust in multicyclones above 1,200 °F. Sintered ULTRON and dense alumina complete the range.
The grade is chosen per application, from the particles, the temperature and the chemistry, not from a table of hardness values.
Equipment that moves, grinds or depressurizes slurry wears at the surfaces that see the highest velocity.
Seats, balls, discs, gates and body linings for slurry, ash and mill discharge valves.
Suction side liners, impeller faces and volutes, new or fitted to worn pump plates.
One-piece bowl liners, nozzles and vortex finders for jet mills, cast to fit the steam ring.
Large silicon carbide shapes for autoclave flash pots, quench vessels and vent blast tubes.
Every part in this group starts with the part that fails today. Its dimensions, the medium, the temperature and how often it fails are enough to begin.
A Blasch engineer chooses the grade and designs the part. It is cast near net shape in Albany, fired, and assembled into steel where needed, so it goes in like the part it replaces.
Some wear parts sit where heat and thermal cycling matter as much as the solids.
Sleeves, linings, bubble caps and tuyeres for fluidized bed and chlorination reactors.
Precast, fired inlet cones for ethylene furnace exchangers, with no cure out on site.
Setters that hold ceramic cores for turbine airfoils true through repeated firings.
It depends on the wear. Silicon carbide grades are harder and handle heat and thermal shock better; dense alumina is a good fit for many abrasive services at lower cost. The engineer chooses per application.
Yes. Parts are built to the dimensions and connections of the part they replace, so pipes, cyclones, pumps and valves keep their layout.
Send the dimensions of the worn part, what flows through it and how long it lasts today. A Blasch engineer takes it from there.
Yes, as separate groups. See ceramic nozzles and the full product range.
Tell us where it sits, what it is made of today and how long it lasts. A Blasch engineer answers with a ceramic part designed for that spot.
