High Pressure Cold Drawn Steel Pipe , Cold Rolled Steel Tube P92 2'' 60.3mm OD
XIAN New Force 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.
In order to improve the heat efficiency of reheating steam pipeline in power plant, the reheating-temperature can be designed as high as 621°C, which is known as the super-critical temperature. The Unite States firstly developed ASTM A335 P92 alloy steel in late 1980’s to meet the heat-resisting requirements of such a high-temperature power unit. The alloy steel P92 is an improved version of ASTM A335 P91 alloy which has deliberate addition of tungsten, vanadium, niobium, decreased amount of molybdenum to fine-tune to ferrite/austenite ratio, as well as carefully controlled amount of boron and nitrogen.
