USA Industrial Sewage Pipeline Project

1. Project Overview

This environmental upgrade project is located in a large industrial park in California, USA, used for centralized collection and high-pressure transportation of industrial wastewater. American municipal engineering standards are extremely strict in pressure resistance, acid and alkali corrosion resistance, welding performance and product certification. After international bidding, laboratory testing and factory auditing, Pengyuan Steel was officially selected as the designated seamless pipe supplier for this project.

2. Project Challenges

• The pipeline transports corrosive industrial wastewater requiring excellent internal anti-corrosion performance. • Long-term high-pressure working conditions demand stable mechanical performance and zero leakage. • Full compliance with ASTM and AWWA American engineering standards. • Strict third-party inspection and standardized batch delivery required.

3. Supplied Products

Product: ASTM A106 Gr.B high-pressure seamless steel pipes with internal and external anti-corrosion treatment Size: OD114mm–OD377mm, wall thickness 4.0mm–10mm Total Quantity: 1,420 tons Standard: ASTM A106, AWWA standard

4. Pengyuan Solutions

• Adopted high-standard ASTM A106 Gr.B raw materials to ensure stable pressure resistance and toughness. • Professional internal and external anti-corrosion treatment for acid & alkali wastewater resistance. • 100% non-destructive testing, ultrasonic inspection and hydrostatic test for every pipe. • Complete English MTC certificates and full traceability documents provided. • Standard container shipment and full quality tracking support.

5. Project Result

All steel pipes passed strict third-party inspection and American engineer acceptance at one time. The pipeline system operates stably with excellent corrosion resistance, fully meeting US environmental protection and water supply engineering standards. Pengyuan Steel has become a qualified supplier for American municipal environmental projects.
