Baodi Petrochemical Closed-Die Forging Case, Tianjin

Case Overview

This case study examines the closed-die forging project undertaken by Jianing Forging for a major petrochemical enterprise in Tianjin. The project required high-precision components capable of withstanding extreme pressure and corrosive environments. Jianing Forging was selected to deliver custom-forged parts that met rigorous industry standards.

Customer Challenges

The client faced several critical issues: conventional casting methods resulted in inconsistent material density, leading to premature failure under high cyclic loads. Additionally, the geometric complexity of the required components made machining from solid billets cost-prohibitive and time-consuming. Surface defects and internal porosity further compromised product reliability, causing frequent maintenance shutdowns and increased operational costs.

Our Solution

Jianing Forging developed a tailored closed-die forging process that addressed each pain point. By utilizing advanced finite element analysis for die design, we optimized metal flow to eliminate porosity and achieve uniform grain structure. The closed-die technique enabled near-net shape production, reducing material waste by over 30% and minimizing subsequent machining. Post-forging heat treatment was precisely controlled to enhance mechanical properties, while rigorous non-destructive testing ensured defect-free output. The result was a set of durable, high-strength components with consistent performance in demanding petrochemical environments.
