ST - Full cone spray nozzle
ST full cone nozzle is designed for use with abrasive materials such as limestone slurry, with Cobalt alloy 6 or RBSC ceramic parts in high-wear areas. ST nozzle is commonly used for wet FGD (flue gas desulphurization).
The ST spray nozzle generates fine atomisation and has a large free passage, which reduces the risk of clogging.

Choose the right spray nozzle for an optimised spray process
Each type of nozzle has a specific flow rate, spray pattern and droplet size. To optimise the spray process, it is important to understand how different parameters affect the choice of spray nozzle and type of solution.
The Knowledge base contains information about spray pattern, droplet size, flow rate/pressure, spray coverage, materials, etc. The 'Materials' section of the Knowledge base lists the most commonly requested materials and maximum temperature of the material.
Our main supplier is BETE, a leading manufacturer of spray nozzles and spray systems with more than 70 years of experience in spray processes and a product range including over 20,000 components.
BETE's spray technology is used worldwide to optimise processes in many different industries, including the energy sector, chemical and petrochemical industry, food industry and offshore.
