штанговых Централизатор

This company produces reinforced nylon stabilizer, the maximum diameter Φ58mm, length Φ125mm, apply Φ25, Φ22, Φ19 rod to use, the card does not occur anywhere in the sucker rod,resolving the long-standing unresolved wells in Zhongyuan Oilfield partial abrasion, extend tube, rod, pump life and reduce the operating frequency, significantly reduce the cost of crude oil production, but also played the role of scraping wax. The products is serve nylon as the main raw materials and foreign recipes, they are produced with a stabilizer, plasticizer, anti-aging agent, reinforcing agent and other raw materials. The design was streamlined, with the oil flow passage, with good wear resistance and self lubricating, light, temperature, crude oil has a good corrosion resistance, its mechanical properties with tensile, compressive, impactthe advantages of high strength, weight does not increase pumping capacity.Technical Standard NamePerformanceAppearance Light yellowRatio 1.14Tensile strength MPa54-78Compression strength MPa60-90Bending strength MPa70-100Hardness (Rockwell R)85-114Melting point °C215-223Linear expansion coefficient 10-5/C7.9-8.7Water absorption rate %1.9-2.0Lock tight power KN40Horizontal force KN22.8Vertical force KN55.6 Stabilizer and sucker rod centralizer assembly method: 1, hot charging method: the temperature at 80-100 ° C mounted on the rods within the preheating. 2, cold installation method: in room temperature, fitted to the rods.
