Introducción a la chapa de acero para recipientes

In fact, the vessels is a big category among many steel plates, which has very special composition and many excellent properties. At present, this kind of vessels plate is mainly used to make pressure vessels in the market. For different situations and different uses, the corresponding materials to be made are also different. This kind of […]

5 métodos de ensayo no destructivos para el acero

The nondestructive testing of steel mainly involves ray testing, ultrasonic testing, magnetic particle testing, penetration testing and eddy current testing.  1. Radiographic Detection (RT)X-ray testing refers to the non-destructive testing method that uses X-ray or gamma ray to penetrate the specimen and uses film as the equipment for recording information. This method is the most […]

Material de acero al carbono para aplicaciones de corrosión por sulfuro de hidrógeno

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 [...]

Soldadura de material de calderas ultrasupercríticas

Heat-resistant steel refers to the steel that works at high temperature and has excellent thermal strength and thermal stability. Thermal strength refers to the ability to resist creep and fracture at high temperature, and thermal stability refers to the ability to resist oxidation and corrosion of gaseous media at high temperature. People usually refer to the heat-resistant […]

¿Para qué se utiliza el acero resistente a la fluencia?

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 […]

¿Cómo afectan los elementos de aleación al rendimiento de los aceros criogénicos?

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 […]

Soldabilidad de la tubería de revestimiento J55

The oil casing is composed of a collar and pipe body. A single pipe body is connected with the collar thread and transported to the oil field site with end to end connection to facilitate transportation and use after reaching the required length. In order to strengthen the strength and anti-loosening control of the threaded connection, […]
