The single length of the sucker rod is 7.62 or 8 meters, 9.14 meters, and the material is generally low-carbon alloy steel after quenching and tempering treatment. It is connected one by one with internal thread hoops in the oil pipe and extends to the piston at the underground oil layer. The oil is pumped by reciprocating motion. The length of the current oil well is generally about two kilometers. Take Shengli Oilfield as an example, the deepest is more than three thousand meters
Aug 12, 2022 read moreAlumina plate and aluminum plate cannot achieve the purpose of alloy strengthening in the quenched state. The strength of the deformed aluminum alloy material that has just been quenched is only slightly higher than that in the annealed state, but the elongation is appropriately high. For finishing operations such as stretching and straightening, natural aging can start immediately after quenching, or it can start after a certain incubation period. This heat treatment process is called aging.

Aug 10, 2022 read moreWhat causes the uneven color of the aluminum oxide film? Specifically, there are three main issues: (1) The workpiece area of the aluminum plate is too large, the swing in the groove is too large during operation, and the contact, renewal and exchange between the edge and the center part and the solution are too different, resulting in inconsistent color of the oxide film. Prevention method: When the aluminum plate is oxidized, the swing of the workpiece should be small, and static treatment is also possible, but when the temperature of the solution is too low, map-shaped spots are prone to appear, which is unnatural.
Aug 04, 2022 read moreWhether it is an aluminum plate or an aluminum alloy material, a very important process is the surface treatment. Today, I will introduce the current mainstream aluminum plate surface treatment technology. One: Electrophoretic paint. After the aluminum plate is treated in this way, the surface of the material presents a smooth side, and the corrosion resistance is also greatly enhanced. Two: powder electrostatic spraying. The feature of this process is to enhance the corrosion resistance of aluminum sheets, and for some acid and alkali salts, the use of aluminum sheets is better than the oxidation-colored profiles. Three: multi-tone surface treatment. At present, in order to make the aluminum plate work better together, various color treatments have naturally appeared, so that.

With the progress of large equipment, there are many aluminum plates with a maximum width of 600mm).
Aug 02, 2022 read moreThe speed of natural aging of different alloys of aluminum alloy plates is very different. Some alloys only need a few days, while some alloys need several months or even years to approach a stable state. , the recrystallization process cannot be completed, the supersaturated solid solution cannot be completely synthesized, and some work hardening and quenching effects are still preserved. It is difficult to continue cold rolling without annealing, so it is necessary to stop slab annealing.
