Sulfuro de hidrógeno H₂S es un compuesto inorgánico que es incoloro, inflamable, soluble en agua gas ácido, la corrosión por sulfuro de hidrógeno se refiere a la tubería de petróleo y gas que contiene una cierta concentración de sulfuro de hidrógeno (H2S) y la corrosión del agua. El H₂S se disuelve en agua y se vuelve ácido, lo que provoca corrosión electroquímica y picaduras y perforaciones locales en las tuberías. Los átomos de hidrógeno [...]

Molybdenum has been a key alloying element in creep resistant ferrite steels operating at temperatures up to 530°C. The main applications of creep resistant steel are in power plants and petrochemical plants, where steam turbines require large forgings and castings, and pressure vessels, boilers and piping systems require tubes, plates and accessories of all kinds.In addition […]

We usually call the steel used the temperature range -10 to -273℃ as low-temperature steel or cryogenic steel According to alloying element content and structure, cryogenic steels can be divided into: Aluminum killed C-Mn steel such as 06MnVTi, 06MnVal, 09Mn2Vre, 06MnNb steel, low alloy ferric body low-temperature steel 0.5Ni, 2.5Ni, 3Ni, 3.5Ni, etc., Martensiform low-temperature […]

U tube heat exchanger is characterized by its simple structure, good tightness, convenient maintenance and cleaning, low cost, good thermal compensation performance and strong pressure bearing capacity. The U-tube heat exchanger has the largest heat exchange area under the same diameter. The main structure of U-shaped tube heat exchanger includes tube box, cylinder, head, heat exchange tube, […]

N80 petroleum casing and N80 seamless steel pipe are important equipment for oil drilling, whose main equipment also includes drill pipes, core pipes and casing, drill collars and steel pipes for small diameter drilling. N80 petroleum casing and N80 seamless steel pipe have three kinds of lengths specified in the API standard: namely, R-1 for […]
