Hot Finished Seamless Alloy Steel Pipe ASTM A335 P92 Material
For thermal power plant, enhanced working pressure and temperature requires more critical materials like P92. USC boiler demands more critical material and works at higher temperature and pressure but more efficient and cleaner. TIPTOP had been focusing on new material development such as P92.
TIPTOP is providing ASTM A335 P92 alloy steel seamless pipes, which are mainly used for high-temperature service. P92 pipe a kind of chrome moly pipes listed in ASTM A335, a standard in power generation and petrochemical industry. TIPTOP supply a full range of A335 chrome moly pipes.
