摘要： In a process for applying a friction-resistant coating to a steel sucker rod, the rod is passed, in sequence, through a surface preparation stage (for example, scale removal, shot peening, or other suitable method), an adhesive application stage (to enhance the strength of the coating's bond to the rod), an extrusion stage (in which the rod is passed through a die in conjunction with a flow of melted polymeric coating material), and a cooling (coating solidification) stage. Typically, the radial thickness of the coating will be between 0.125 and 0.375 inches. The process is adaptable to apply extruded coatings to continuous rod or to individual sucker rods having upset ends. The coating may be selected from but is not limited to high-density polyethylene, cross-linked polyethylene, polyvinylidene fluoride, ethylene tetrafluoroethylene, polytetrafluoroethylene, polyphenylensulfide, nylon, polyester, polyethersulfone, polyethylene terephthalate, polypropylene, polystyrene, epoxy, or acetyl.

摘要翻译：在向钢吸棒施加耐摩擦涂层的过程中，杆依次通过表面准备阶段（例如，除垢，喷丸硬化或其它合适的方法），粘合剂施加阶段（以提高涂层与棒的结合强度），挤出阶段（棒与熔融的聚合物涂层材料的流动一起通过模具）和冷却（涂层固化）阶段。通常，涂层的径向厚度将在0.125和0.375英寸之间。该方法适用于将挤出的涂层施加到连续的杆或具有镦粗端的单个抽油杆。涂层可以选自但不限于高密度聚乙烯，交联聚乙烯，聚偏二氟乙烯，乙烯四氟乙烯，聚四氟乙烯，聚苯硫醚，尼龙，聚酯，聚醚砜，聚对苯二甲酸乙二醇酯，聚丙烯，聚苯乙烯，环氧树脂或乙酰基。
