Product Details
Tantalum Spray Nozzle
As the owner of a petro-chemical plant you might encounter such problems as the corrosion and wear of equipment and parts. Raytec has a team of skilled and competent engineers, metallurgists and technicians to assist in the design development, production and construction of projects in many industries.
The tantalum and ta2.5w spray nozzle have been successfully used in
(1) Feed injection nozzles for waste sulphuric acid incineration plant;
(2) Hypochloride pump for chloro-alkaline plant, and many other applications.
(3) Other corrosive and abrasive environment.
