Material of empty tower nozzles
Thread Content
The spray nozzles in the clean air towers used for acid production from 120,000 tons of pyrite in our company are made of lead-antimony material, and they tend to get damaged frequently. I would like to ask what material you use? How long is the cycle?
Which manufacturers sell tetrafluoride spiral nozzles?
Silicon carbide is the best choice; it should last at least 10 years, as it is wear-resistant and does not corrode
Using silicon carbide is the right choice! However, attention must be paid to the purity of silicon carbide; if it contains a high amount of free silicon, its corrosion resistance is poor and it is prone to breaking! Recommended Hexoloy products
The spiral nozzles made of PTFE are excellent; the pipes used for connections are lined with steel wire wrapped in PTFE, while those inside the empty tower are made of PTFE tubes, which do not break even after several years of use.
