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.

A metallurgical equipment factory in Pingliang, Gansu, due to production needs, commissioned us to process a batch of high-standard cylindrical forgings. This batch of forgings will be used in key parts of core equipment, with strict standards for material performance, dimensional accuracy, and internal quality. Based on the technical parameters provided by the customer, we complete the entire process from forging process design to finished product delivery.

During the early trial production process, the metallurgical equipment factory encountered several problems: First, the wall thickness of the barrel forgings was relatively large, making conventional forging methods difficult to achieve internal tissue uniformity, which easily led to segregation or loosening defects; Second, the customer requires dimensional tolerances to be kept within 0.5mm and must pass ultrasonic flaw detection (UT) inspection, which the original supplier cannot consistently meet this level of precision; Third, the delivery cycle is tight, and the customer worries that the traditional process takes too long and may affect equipment installation progress.

To address these pain points, we offer the following solutions: First, by combining multi-directional forging and temperature-controlled forging, combined with optimized deformation distribution, internal tissue unevenness is effectively eliminated, and the finished product passed UT testing on the first attempt; Second, by using CNC grinding rings and precision processing equipment, the roundness and straightness tolerances of the cylinder were stably controlled within 0.3mm, exceeding customer requirements; finally, by conducting process simulations in advance and coordinating production schedules, the delivery cycle was compressed to two-thirds of the original plan, helping the customer smoothly connect to installation nodes. This batch of cylinder forgings has been put into use and is operating well, and the customer has placed additional cooperation orders later.
