Shanxi Jianing Forging adopts mature precision die forging processes, capable of producing gears, valve bodies, automotive swing arms, piston rods, and impeller die forgings. It offers high dimensional accuracy, and can be processed from carbon steel, stainless steel, and alloy steel, meeting the needs of multiple industries.
In petroleum drilling operations, drill pipe joints endure relatively high torsional loads and frequent impact vibrations. Ordinary castings or machined parts often fracture early due to internal defects and stress concentration, affecting drilling efficiency and safety. The drill pipe joint die forgings produced by Jianing Forging use an integrated die forging process, resulting in complete metal flow lines, fully eliminating risks of casting shrinkage loosening and porosity, and providing more
In petroleum drilling operations, drill pipe joints endure relatively high torsional loads and frequent impact vibrations. Ordinary castings or machined parts often fracture early due to internal defects and stress concentration, affecting drilling efficiency and safety. The drill pipe joint die forgings produced by Jianing Forging use an integrated die forging process, resulting in complete metal flow lines, fully eliminating risks of casting shrinkage loosening and porosity, and providing more reliable connection support for harsh working conditions.
Drill pipe joint forgings are key connecting components in petroleum drilling tool systems, produced by Jianing Forging using high-quality alloy steel as raw material, through fine die forging, heat treatment, and machining. The product has a dense internal structure with balanced strength and toughness, compatible with various specifications of drill pipes and wellhead tools, meeting API and other relevant standards.
Integral die forging: metal streamlines are distributed along the part contour, improving fatigue resistance and impact resistance.
Optimized material ratio: Selected from industry-recognized alloy steel grades, strictly controlled by chemical composition and heat treatment processes to balance hardness and toughness.
High-precision dimensional tolerances: Using CNC machining and professional measuring tool inspection, it helps threads fit tightly with sealing surfaces, reducing on-site installation failures.
Surface reinforcement treatment: Optional phosphating, copper plating, or wear-resistant coatings enhance corrosion resistance and anti-stick grip, extending service life.
This product is a customized die forging, and the specific price should be calculated comprehensively based on material, specifications, quantity, and surface treatment requirements.
