Wall Thickness | 4.83-16mm |
Forms of thread | External upset, Non upset |
Function | It is used to transfer oil and gas. |
Steel Grade | Material | Delivery Status | |
J55 tubing | 37Mn5 | NUE tubing | Hot rolling replaces normalizing. |
EUE tubing | Full-length normalizing after thickening |
In accordance with the delivery status, our J55 oil transfer steel tubing can be classified as NUE type and EUE type. The NUE type product adopts hot rolling instead of normalizing treatment, featuring high hardness and reliable performance. The full length of EUE type product is treated by normalizing process after being thickened, which can improve the mechanical properties and eliminate the stress. Furthermore, both plasticity and toughness can be increased. All these advantages make our product widely applicable to the oil well. To ensure the sealing performance of API tubing, our company also adopts hydraulic process.
