Product Specification

Austenitic Stainless Steel Pipe for High-Performance Systems (ASTM A312 / DIN EN 10217-7)

Introduction
TOBO's Austenitic Stainless Steel Pipes represent the pinnacle of modern metallurgical engineering, designed to meet the most stringent demands of critical global industries. These pipes are meticulously manufactured in full compliance with leading international standards, including the American ASTM A312 and German DIN 11866 specifications, ensuring consistent material properties and dimensional accuracy for seamless integration into global projects. They are the material of choice for applications where reliability, corrosion resistance, and long-term performance are non-negotiable, from sterile pharmaceutical processing to high-pressure energy systems.

1. Product Description
Our Austenitic Stainless Steel Pipes are available in both seamless and welded configurations, adhering strictly to the guidelines for dimensions, materials, and surface finish as outlined in standards like ASTM A312/A312M and DIN 11866. The austenitic microstructure provides a unique combination of strength and ductility. Available in various grades such as 304/L and 316/L, these pipes are designed for specialized applications in aseptic, chemical, pharmaceutical, and general corrosive or high-temperature service environments.

2. Key Parameters
The pipes are produced with external diameters ranging from 6.35 mm to 219.1 mm, catering to a wide array of system designs. All pipes are supplied in a heat-treated condition to optimize their metallurgical structure. They undergo rigorous mechanical testing, including tensile strength and flattening tests, to verify performance against specified minimums for yield and tensile strength. Each length is also subjected to non-destructive electric tests or hydrostatic tests to ensure structural integrity and leak-proof reliability under pressure.

3. Product Applications
TOBO's stainless steel pipes are engineered for versatility. Their primary applications include the construction of hygienic tubing systems for the pharmaceutical and food industries, where surface finish and material purity are critical. They are equally vital in the chemical and petrochemical sectors for transporting corrosive media, and in power generation for high-temperature steam and feedwater lines. They also serve in demanding architectural and structural applications.

4. Product Advantages
These pipes offer superior corrosion and heat resistance, capable of operating effectively in temperatures from -196°C to 800°C. The excellent low-temperature strength prevents brittleness, while the inherent ductility allows for excellent formability, such as bending and welding, without the risk of hardening from heat treatment. They demonstrate exceptional performance under high-pressure and high-velocity flow conditions, with some proprietary formulations offering enhanced properties like increased yield strength and improved wear resistance.

5. Product Functions
The core function of our austenitic stainless steel pipe is to provide a safe, durable, and efficient conduit for fluids and gases in critical applications. They are designed to maintain system purity, prevent contamination in sensitive processes, and withstand thermal stress and corrosive attack over decades of service. Their reliability helps minimize maintenance downtime, reduce long-term lifecycle costs, and ensure the continuous, safe operation of essential industrial infrastructure.
