We have expertise in producing and supplying a diverse selection of conventional pump rods and polished rods. Our rod options cover various grades of steel like C, K, D, KD, H, HL, HY, and more. Our polished rods are meticulously polished or chrome-plated and coated with a tungsten alloy layer. Alongside rods, we provide a range of accompanying accessories such as sucker rod nipples, couplings, nylon couplings with variable diameters, roller and nylon centralizers, polished rod clips, sealing devices, and numerous other products.
Product Application of sucker rod :
Sucker rods, commonly used in oil extraction, play a vital role in delivering power within the oil well system. These rods are produced through a series of processes such as testing, straightening, and forging. They are typically placed between the polished rod and the oil well pump. Sucker rods are crafted from high-quality carbon steel and alloy steel, adhering to the API Spec 11B standard. They come in different types, including the common sucker rod, hollow sucker rod, and FRP sucker rod. Connecting these rods is made possible through sucker rod couplings. Moreover, various specifications of sucker rods are available to suit different environmental conditions and applications.
