Supplying 32″ ASTM A106 Gr.B Welded Pipes for Côte d’Ivoire

Haihao Group recently completed the production and quality inspection of large-diameter 32″ ASTM A106 Gr.B welded pipes for a valued customer in Côte d’Ivoire. These pipes, featuring a single longitudinal weld seam, are designed for high-temperature and high-pressure pipeline systems. To ensure their performance, we conducted comprehensive quality tests, including ultrasonic thickness testing, chemical composition analysis, and visual inspections.

ASTM A106 Gr.B Large Diameter Welded Pipes

What is ASTM A106 Gr.B Pipe?

ASTM A106 Gr.B is a carbon steel pipe designed for high-temperature fluid transportation in industries such as oil, gas, petrochemical, and power generation. It is commonly used in seamless form, but for large-diameter applications (above 24”), welding is required to achieve the necessary size while maintaining structural integrity.

Key Features of ASTM A106 Gr.B Welded Pipes:

Single Weld Seam – Ensures strength while allowing large-diameter production.

High-Temperature Resistance – Operates up to 425°C (800°F) in industrial applications.

Excellent Mechanical Properties – Provides high tensile strength and impact resistance.

Custom Sizes & Thicknesses – Designed to meet specific pipeline project requirements.

Applications of Large-Diameter ASTM A106 Gr.B Pipes

32” welded pipes are essential for high-capacity pipeline systems requiring both structural stability and fluid transport efficiency. These pipes are widely used in:

• Oil & Gas Transmission – Used for crude oil and natural gas transport in offshore and onshore pipelines.
•  Petrochemical & Refinery Systems – Supporting the movement of chemicals and processed fluids.
• Power Plants & Steam Systems – Withstanding high-pressure steam and thermal expansion.
• Industrial Water & Wastewater Pipelines – Large-scale distribution networks for industrial facilities.
