Engineered Flow Solutions: TOBO Austenitic Steel Pipes | ASME

TOBO Austenitic Stainless Steel Pipes are designed to meet the critical demands of modern engineering, offering an optimal blend of corrosion resistance, mechanical strength, and fabrication versatility. Produced under strict ASME quality assurance protocols, these pipes leverage the inherent benefits of the 300-series stainless steel family. Their austenitic crystalline structure, achieved through alloying with nickel and chromium, ensures exceptional toughness and ductility across a wide temperature spectrum, from deep cryogenic to elevated heat. As a cornerstone material for countless industries, they deliver proven performance, ensuring system integrity, safeguarding product purity, and minimizing lifetime maintenance costs.

1. Product Description
Our Austenitic Stainless Steel Pipes are manufactured from high-purity alloys, with primary grades including AISI 304/L and 316/L. The “L” designation indicates a lower carbon content, enhancing resistance to sensitization and intergranular corrosion post-welding. Available in both seamless (cold-drawn) and welded (autogenously welded and cold-worked) forms, these pipes are finished to superior surface quality standards (e.g., bright annealed, pickled). This makes them suitable not only for functional fluid transport but also for applications where aesthetic appearance or ultra-clean surfaces are required.

2. Key Specifications

• Material Standards: Conform to ASTM A312 for seamless and welded pipes, and ASTM A358 for electric-fusion-welded pipe.

• Common Grades: TP304/304L, TP316/316L, TP321.

• Dimensional Compliance: Manufactured to ASME B36.19M specifications, ensuring precise outer diameters and wall thicknesses.

• Standard Sizes: Extensive inventory from 1/8" NPS to 24" NPS.

• Pressure & Temperature Ratings: Designed to meet ASME B31.3 Process Piping code requirements for various service conditions.

3. Application
TOBO Austenitic Pipes serve as essential components in a diverse range of sectors:

• Food, Dairy & Brewing: Sanitary process lines, fermentation tanks, and product transfer lines requiring easy cleaning and sterilization.

• Pharmaceutical & Biotech: High-purity water (WFI, PW) systems, clean utilities, and process piping in validated facilities.

• Semiconductor & Electronics: Ultra-high-purity gas and chemical delivery systems for fabrication plants.

• Oil & Gas (Midstream/Downstream): Non-corrosive service lines, instrumentation tubing, and fuel handling systems.

• Architectural & Interior Design: Exposed piping, handrails, and decorative structures valuing both aesthetics and longevity.

4. Key Advantages

• Broad Chemical Compatibility: Resists oxidation and a wide array of organic chemicals, acids, and alkalis, with Grade 316 offering superior pitting resistance in chloride environments.

• Excellent Low-Temperature Performance: Maintains toughness and does not become brittle, making it ideal for cryogenic applications like LNG handling.

• Ease of Fabrication & Installation: Can be easily cut, welded, bent, and formed using standard shop equipment, reducing installation time and complexity.

• Non-Magnetic & Hygienic Properties: The inherently non-magnetic nature and smooth surface finish prevent scaling and bacterial adhesion, crucial for regulated industries.

• Sustainable Choice: 100% recyclable with a long service life, contributing to environmentally conscious project design.

5. Function
The core function of TOBO Austenitic Stainless Steel Pipes is to provide a high-integrity, contaminant-free pathway for fluids and gases. They are engineered to preserve the quality of the conveyed medium—whether it’s food, pharmaceuticals, high-purity chemicals, or water—while withstanding internal pressure, thermal cycling, and external environmental exposure without corrosion or degradation. This ensures operational safety, protects capital equipment, and guarantees consistent process output.
