Welcome to Suzhou Industrial PARK Qingsen Trading Co., Ltd. We are your premier destination for high-performance Inconel Tube/Pipe solutions. As a specialized supplier with deep manufacturing integration, we deliver top-tier nickel-based alloy tubes. These products are engineered specifically for extreme environments. Whether you need standard catalog items or highly customized tubing, our network is equipped to deliver. We ensure all materials strictly comply with global standards like EU RoHS and ASTM. This guarantees reliable, high-strength piping for your most critical operations.
We offer a comprehensive selection of alloy grades designed to meet rigorous industrial demands. These nickel products are globally recognized for exceptional resistance to extreme heat, severe corrosion, and intense mechanical stress. Below is an overview of our most highly searched alloys and their core properties.
The Inconel 600 pipe is a standard engineering material. It is ideal for applications requiring robust resistance to both corrosion and heat. Alloy 600 features excellent resistance to high-temperature oxidation. It is also virtually immune to chloride-ion stress-corrosion cracking. This makes it perfect for chemical processing, heat-treating, and nuclear engineering.
For environments demanding superior oxidation resistance at elevated temperatures, the Inconel 601 tube is an excellent choice. It maintains high mechanical strength and resists aqueous corrosion effectively. This grade is frequently utilized in thermal processing equipment and pollution control systems.
Known for high strength and outstanding aqueous corrosion resistance, Inconel 625 seamless tubing performs exceptionally well in severe environments. This grade is highly sought after for aerospace and marine applications. In these sectors, fatigue strength and resistance to localized corrosion are absolutely critical for operational safety.
The Inconel 718 pipe is a precipitation-hardenable nickel-chromium alloy. It contains significant amounts of iron, niobium, and molybdenum. Alloy 718 exhibits exceptional yield, tensile, and creep-rupture properties at temperatures up to 1300°F (700°C). These characteristics make it ideal for demanding environments in the petrochemical and power generation sectors.
Selecting the right dimensions and technical specifications is crucial for project success. We act as a dedicated technical resource for engineers and procurement managers. Our team provides detailed material data to ensure our products meet your exact engineering requirements.
Our inventory includes a wide range of standard dimensions to accommodate various industrial needs. The following chart outlines common outside diameters (OD), wall thicknesses, and schedules for our piping products.

What is the difference between Inconel pipe and Inconel tube?
Inconel pipe is generally measured by nominal pipe size (NPS) and schedule, primarily used for fluid transport. Conversely, Inconel tube is measured by exact outside diameter (OD) and wall thickness. We typically recommend tubing for structural or heat transfer applications requiring high precision.
Do your Inconel 625 pipes comply with international aerospace and industrial standards?
Yes, our seamless and welded pipes strictly comply with international standards. This includes ASTM, AMS, and EU RoHS certifications. We ensure reliable performance in extreme environments for all our clients.
Can you provide custom dimensions for seamless tubing?
Absolutely. Utilizing our self-developed cold drawing process, we offer millimeter-level precision customization. Our engineering team will work with you to meet the exact dimensional requirements of your specific project.
