| titleOfInvention | Diameter is the production method of the pipeline with hydrogen sulfide corrosion resistance seamless steel pipe of 508mm |
| abstract | The invention provides the production method that diameter is the pipeline with hydrogen sulfide corrosion resistance seamless steel pipe of 508mm, the steel grades comprising employing meets following formula Cev=C+Mn/6+ (Cr+Mo+V)/5+ (Cu+Ni)/15 [%] > 0.20 and Pcm=C+Si/30+ (Mn+Cu+Cr)/20+Ni/60+V/10+5B [%]≤0.20 by weight percentage; Smelting process; Tube-rolling technique is; Technology for Heating Processing.It is 508mm super large caliber pipeline with hydrogen sulfide corrosion resistance seamless steel pipe that method provided by the invention can produce external diameter, this steel pipe yield strength is at more than 380MPa, tensile strength is at more than 460MPa,-20 DEG C of ballistic works are at more than 200J, and by HIC (NACE TMO284-2003), the test of the hydrogen sulfide corrosion resistant such as SSCC B method (NACE TMO284-2003) and SOHIC (NACE TMO103-2003), can be applied to X52 ~ X65 grade of steel seamless steel pipe for line pipe under the higher sour environment of sulfide hydrogen. |
