Steel sucker rods are the main equipment in oil fields. We offer C-grade, D-grade, K-grade, KD grade, HL grade, HS grade, and special alloy sucker rods, all manufactured in accordance with API Spec 11B. The C-grade sucker rod is made of high-quality carbon steel, with moderate strength, good plasticity, and good corrosion resistance. C-grade sucker rods are suitable for sulfur-containing media environments and are insensitive to sulfur stress cracking.

The drive rod for the screw pump is available in diameters of 1 inch (25.40 mm), 1 1/4 inches (31.75 mm), and 1 1/2 inches (38.10 mm), with a length of 25 feet (7.62 meters).

加重杆在泵上方提供集中的重量来保持抽油杆柱的平直和张力，从而减少抽油杆或泵柱塞的屈曲。加重杆是由热轧碳锰钢棒料制成的。加重杆是旋转表面，两端有API规格的抽油杆螺纹、台阶和扳手方。一端车制打捞镜用于提升。

T级和SM级的抽油杆接箍按照API 11B制造。T级接箍使用AISI 5140制造。至于SM级接箍，喷焊金属是在原材料上使用的特定硬化工艺。接箍有全尺寸、小井眼和大尺寸可供选择。此外，变径接箍可用于不同直径的T级和SM级接箍。
