Shanxi Jianing Forging can process large-diameter pressure vessel shell forgings made of carbon steel, stainless steel, and alloy steel. The station has a wealth of real-world cases of cylinder forging, fully demonstrating the forging capabilities of large-size cylinders and the corrosion-resistant results of finished products.
In the petrochemical heavy industry sector, shell forgings are among the core components, and their quality directly affects the safety and service life of the equipment. Drawing on years of experience in large-scale forging manufacturing, Jianing Forging provided high-performance cylindrical forging solutions for a petrochemical heavy plant in Hengyang, Hunan, helping customers achieve normal equipment operation and on-time project delivery.
The partner for this cooperation is a petrochemical heavy factory in Hengyang, Hunan. The new project requires supporting large cylindrical forgings for key reaction devices. Jianing Forging undertook the overall forging and finishing tasks for this batch of cylinder forgings, covering the entire process from raw material incoming to the factory to finished product delivery.
The client faced multiple challenges during project advancement: first, the cylinder size was relatively large, with a special wall thickness to diameter ratio, making conventional forging processes difficult to achieve internal tissue uniformity; Second, the material must have good high-temperature strength and corrosion resistance, with strict requirements for chemical composition and heat treatment processes; Third, delivery times are tight, requiring the production and inspection of large-tonnage forgings to be completed in a short time; Fourth, high dimensional accuracy requirements must help ensure reliability in subsequent machining and assembly.
To address these pain points, Jianing Forging offers a systematic solution: using multi-directional forging and temperature-controlled forging technologies to optimize grain flow direction and density, helping to balance the longitudinal and transverse mechanical properties of the cylinder; By adjusting specialized heat treatment process parameters, forgings maintain stable yield strength and impact toughness even at high temperatures; At the same time, full-process digital management has been introduced, strictly controlling every stage from ingot smelting to finished product flaw detection, shortening production cycles. The final delivered shell forgings were tested by a third party, and all indicators met the customer's design specifications, helping the project smoothly enter the next phase.
