Applications
Titanium and Zirconium Pipe Reducer Applications
Often used in high-temperature environments that require high strength-to-weight ratios, titanium and zirconium butt weld pipe reducers add flexibility to piping systems that change in diameter. With strong anti-corrosive properties, these fittings are often used in chemical environments, including:
- Power generation water and steam systems
- Chemical and petrochemical processing plants
- Oil and Gas topside well pipes and offshore drilling systems
Materials
