Shanghai, June 4, 2025 — TOBO Industrial (Shanghai) Co., Ltd., a global leader in metal piping and fittings, has announced the launch of its latest product line: high-performance copper alloy seamless pipes designed for critical industrial applications. With increasing demand for durable, corrosion-resistant, and thermally conductive piping solutions, TOBO’s copper alloy seamless pipes are set to become a preferred choice across marine engineering, power generation, chemical processing, and HVAC systems.
This new product line demonstrates TOBO’s continued innovation and dedication to quality, combining cutting-edge manufacturing technology with decades of metallurgical expertise. The seamless design ensures maximum structural integrity, while the copper alloy composition delivers excellent resistance to corrosion, stress, and thermal fatigue.
Superior Material Composition for Demanding Environments
Copper alloy seamless pipes are known for their exceptional resistance to corrosion, especially in aggressive environments such as seawater, brine, and chemical media. The alloys commonly used—such as CuNi 70/30, CuNi 90/10, Admiralty Brass, and Aluminum Brass—offer a range of benefits including:
High resistance to seawater corrosion and biofouling, ideal for marine and offshore use
Excellent thermal conductivity, perfect for heat exchangers and condensers
Superior ductility and workability, ensuring ease of installation and welding
Outstanding durability in high-pressure and high-temperature environments
TOBO’s seamless pipes are manufactured using strict quality control and hot extrusion processes, resulting in pipes free of internal weld seams, porosity, or weak points—making them highly reliable for critical infrastructure.
Applications Across Industries
Copper alloy seamless pipes play a vital role in multiple sectors due to their unique balance of thermal, chemical, and mechanical properties. TOBO’s newly launched range supports a wide spectrum of applications, including but not limited to:
Marine engineering: Used in seawater cooling systems, desalination plants, and shipboard plumbing
Power generation: Ideal for heat exchanger tubes and boiler systems in both conventional and nuclear power plants
Chemical processing: Resistant to a broad range of acidic and alkaline media
Oil and gas: Applied in offshore platforms and refineries where corrosion resistance is critical
HVAC and refrigeration: Excellent for chilled water systems and air conditioning pipelines
Instrumentation and aerospace: Used where precision, strength, and corrosion resistance are essential
TOBO has also seen growing demand from renewable energy projects and next-generation desalination facilities where durability and low maintenance are key.
Precision Manufacturing and International Standards
All TOBO copper alloy seamless pipes are produced in accordance with leading international standards such as ASTM B111, ASTM B466, EN 12451, and JIS H3300. These standards ensure mechanical integrity, chemical composition, and dimensional tolerances are fully met.
Every batch of pipes undergoes rigorous testing, including:
Eddy current testing for surface defects
Hydrostatic testing to verify pressure resistance
Metallographic inspection to ensure material uniformity
Chemical composition analysis using spectrometry
Dimensional verification with precision measuring instruments
This robust testing regime gives customers confidence that TOBO pipes will perform reliably even under the harshest operational conditions.
Advantages of Seamless Construction
The seamless pipe design provides numerous advantages over welded alternatives, particularly in high-pressure and high-purity systems. Because there are no weld seams, the pipe has:
Uniform strength throughout the entire structure
Improved resistance to leakage under fluctuating pressure and temperature
Lower risk of corrosion at weld lines
Better fatigue resistance, which extends service life
Smoother internal surface, reducing friction and improving fluid flow
These attributes make seamless pipes the default choice for engineers and project managers prioritizing safety, reliability, and long-term performance.
Sustainability and Recyclability
Copper alloys are also 100% recyclable, making them an environmentally sustainable choice. TOBO’s production facilities emphasize low emissions, energy efficiency, and waste minimization, aligning with global sustainability goals. The high scrap value of copper also ensures that systems built using copper alloy pipes maintain value over time, reducing the total cost of ownership for customers.
Global Supply and Customization Options
TOBO offers a wide variety of sizes, wall thicknesses, and alloys to meet different industrial requirements. Custom lengths, end finishes (plain, beveled, threaded), and coatings are also available upon request. Whether supplying small batches for maintenance work or full container loads for large-scale projects, TOBO’s flexible logistics and fast lead times ensure global competitiveness.
With established export markets in North America, Europe, Southeast Asia, the Middle East, and South America, TOBO has built a reliable supply chain that ensures timely delivery and local support.
Commitment to Excellence
Commenting on the launch, TOBO’s international sales director stated,
“Our copper alloy seamless pipes are a result of deep technical know-how, advanced machinery, and strict compliance with global standards. We’re excited to bring a solution to market that provides strength, reliability, and longevity for mission-critical systems around the world.”
