Haihao Group Supplies ASME B16.9 ASTM A234 Gr.WPB Pipe Fittings to Russian Energy Sector

Haihao Group, a global leader in piping solutions, has completed delivery of ASME B16.9 ASTM A234 Gr.WPB pipe fittings to a Russian energy client. The order included 45° and 90° LR elbows, tees, concentric reducers, and eccentric reducers, all manufactured to meet demanding specifications for pipeline infrastructure projects.

The fittings, crafted from ASTM A234 Gr.WPB carbon steel, are designed for high-temperature and high-pressure applications. Each product underwent strict quality controls, from raw material inspection to final packaging. “Our Russian partners required fittings that could withstand extreme operational stresses,” noted a Haihao Group engineer. “We ensured every component met ASME B16.9 dimensional standards and A234 Gr.WPB material requirements.”

Quality assurance measures included:

1. Chemical composition verification via spectral analysis to confirm compliance with A234 Gr.WPB specifications.
2. Dimensional checks using 3D coordinate measuring machines for precise tolerances.
3. Heat treatment to improve grain structure and reduce residual stress.
4. Non-destructive testing (ultrasonic and magnetic particle) to detect internal/surface flaws.
5. Hydrostatic pressure tests at 1.5 times the rated working pressure.

The LR elbows and reducers were particularly critical for the client’s project, as they ensure smooth flow transitions in tight pipeline configurations. The eccentric reducers, designed to prevent air traps, and concentric reducers, for vertical pipe alignment, showcased Haihao Group’s ability to deliver tailored solutions.

Russia’s energy sector increasingly relies on suppliers that combine technical compliance with logistical efficiency. Haihao Group met both needs by coordinating timely customs clearance and providing full documentation, including Mill Test Certificates (MTC) and NDE reports.

The successful delivery reinforces Haihao Group’s position as a go-to source for ASME B16.9 ASTM A234 Gr.WPB pipe fittings. With decades of experience in carbon steel fabrication and a focus on client-specific requirements, we continues to expand our footprint in competitive global markets.
