Description

Sucker rods
Sucker rod is among our leading products absorbing technical essence from home and abroad in accordance with API SPEC 11B, SY/T5029, applying the advanced technology in market and special material developed by Haixin and Xi’an Jiao Tong University to produce high strength and anti-corrosion sucker rod, cooperating with international leading manufacturer to produce several sorts of sucker rod such as Grade HL、HY、KD、D with different properties consisting of high strength and toughness, anti-corrosion and surface spray, used in major oilfield home and abroad. The capacity of sucker rod is 4,500,000meters per year, making good returns through high added value. The sucker rod is a steel rod that used to make up the mechanical assembly between the surface and downhole components of a rod pumping system. The product conforms to API Specification 11B (Oil extraction rod Standard) and other related standard, authorized to use the API monogram. All sizes of sucker rod (standard, heavy, polish rod) which conform to API specification latest version 11B are available in grade K, C, D and HL. Grade
