API 11B Sucker Rods Grade C, K, D, KD, HL, HY And KH For Oil Production
Description of sucker rods:
The Sucker rods are used to connect subsurface sucker rod pump and pump unite. We hold a international advanced upsetting production line with continuous upsetting in eight station, the rod connector has good forging structure and continuous metal streamline, which has high grain size and no overheating burnt, crack, pit, folding and other defects. Besides, it has good advantages of high accuracy forming, high liner degree, uniform organization performance, good corrosion resistance and stress rupture ability, which can preferably solve the problems of losing and unscrewing.

Features of sucker rods:
Grade C sucker rod is made from fine carbon steel. It is featured by mid-strength, good plasticity, toughness, corrosion resistance. It is suitable for sour medium environment where it is not susceptible to sulphuric stress cracking.
Grade D sucker rod is made from fine alloy steel, featured by high strength, better plasticity and long service life after heat treatment. This product is suitable for no-corrosion or light-corrosion environment oil-well widely.
Grade HL and HY sucker rods are super-high strength sucker rod, having the same size and main parameter as grade D sucker rod, but their strength is capable to reach 966~1195Mpa. Grade HL, HY sucker rods are suitable for the deep oil-well or big-pump capacity oil-well.
And grade K, KD and KH sucker rod are made from fine Cr-Ni-Mo alloy steel containing different amount of Ni. They possess more powerful anti-corrosion function. The products are suitable for strong corrosion oil-well, with depth of shallow, middle and deep respectively.
