Haihao Group Delivers High-Precision Forged Bars for Kazakhstan Industrial Project

In support of Kazakhstan’s expanding industrial sector, Hebei Haihao High Pressure Flange Pipe Fitting Group Co., Ltd. has successfully completed the production and export of high-precision forged round bars manufactured under ASME SA-105 standards. These components are part of a critical supply destined for pressure system applications within the region’s energy and infrastructure projects.

Precision Forging for Demanding Applications

The order includes forged bars of Ø40 × 50 mm (-0/+1) and Ø37 × 34 mm (-0/+1), both produced through precision forging and pre-machining processes. Designed for excellent strength and durability, these carbon steel round bars provide a solid foundation for high-pressure fittings, valves, and flange assemblies used in challenging environments.

Haihao Group’s advanced forging facilities ensure tight dimensional tolerances and uniform mechanical properties across every batch. The entire production process is carefully controlled – from raw material inspection to final surface finishing – to guarantee consistency, stability, and long service life.

Advanced Quality Assurance

Each forged bar undergoes a comprehensive inspection and testing program, including:

• Chemical composition verification for base metal consistency.
• Heat treatment to optimize mechanical performance.
• Tensile testing at 20°C to validate strength and ductility.
• Hardness and macrostructure evaluation to confirm structural integrity.
• Full ultrasonic testing (100% UT) in accordance with ASTM A388 and ASME BPVC Section VIII, ensuring internal soundness.
• Carbon equivalent (CE) below 0.47, improving weldability and preventing cracking.

These rigorous controls allow Haihao to deliver forgings that meet or exceed international engineering standards – a key reason why clients in over 100 countries trust Haihao for critical pipeline and mechanical components.
