Tubes d'huile API
The use of steel pipe to manufacture ring-shaped parts can improve the material utilization rate, simplify the manufacturing process, save materials and processing hours, such as rolling bearing collars, jackets, etc., and has been widely used to manufacture steel pipe. (1) The main importing countries of API oil casing are: Germany, Japan, Romania, Czech Republic, […]
Utilisation des tubes de cuvelage dans les puits de pétrole et de gaz
Le tubage pétrolier est un tuyau en acier utilisé pour soutenir la paroi des puits de pétrole et de gaz afin de garantir le bon déroulement du processus de forage et le bon fonctionnement de l'ensemble du puits après son achèvement. Plusieurs couches de tubage sont utilisées dans chaque puits en fonction de la profondeur de forage et des conditions géologiques. Le tubage est [...]
Comment les joints d'isolation en acier sont-ils soudés ?
Insulation joints are mainly used in the sealing protection of oil and gas pipelines and to prevent electrochemical corrosion. They are mainly composed of short joints, steel flanges, fixing rings, seals, insulation plates, insulation sleeves and filling insulation materials. Seals can be O-ring seal, U-ring seal and “O-shaped + U-shaped” composite seal, although the sealing structure […]
Traitement anticorrosion des tôles d'acier de construction
D'une manière générale, le traitement de surface des tôles d'acier de construction est nécessaire pour accroître leur résistance à la corrosion et leur durabilité. La qualité du traitement de surface affecte directement l'adhérence du revêtement au substrat de la pièce revêtue et la résistance à la corrosion du matériau. L'huile, la graisse, la poussière et d'autres contaminants provoquent le décollement du film de peinture ou [...]

Comment prévenir les fissures caustiques？ (Caustic Cracking)
In the last article, we introduced what is caustic cracking, the type of caustic cracking and the harm of caustic cracking. Today here we will continue to describe how to prevent caustic cracking corrosion. Choosing the carbon steel material Carbon steel equipment can be used to hold caustic soda at room temperature, considering the terms of […]
Qu'est-ce que la fissuration caustique dans le pipeline de vapeur ?
Caustic Cracking, also known as caustic embrittlement, is the metals cracking in alkaline solutions due to the combined action of tensile stress and corrosive media, is a type of SCC. The cause cracking of pressure boiler mainly occurs in the parts where steam is repeatedly evaporated and condensed or in contact with caustic soda, which may be carbon steel, low […]
