There are many different materials of oil casing, basic carbon steel, J55, L80, P110 and other special materials such as 3 cr, 9 cr, 13 cr, 22 cr, etc., mainly carbon dioxide resistant and known as hydrogen sulfide resistant materials such as 90 SS, 95 ss, etc. In addition, higher grade and nichrome alloy pipes […]
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, […]
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 [...]
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 […]
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 [...]
