ASME B36.19 SCH 80 Pipe refers to a standard specifically formulated for welded and seamless wrought stainless steel pipes, covering dimensions, wall thickness, and performance requirements for both high and low temperature/pressure applications. Our manufacturers can produce seamless and welded pipes to meet industry requirements. Contact us market@htpipe.com for more information and a free quote!
Advantages of ASME B36.19 SCH 80 Pipe
Durability & Strength
The thicker wall thickness of SCH 80 grade ensures higher tensile strength and impact resistance, eliminating the risk of leaks or burst in high-pressure systems. Seamless and welded manufacturing options (TIG, TIG+plasma, laser welding) enhance structural integrity, making the pipes suitable for long-term use in demanding industrial conditions with minimal maintenance requirements.
Corrosion Resistance
Made of high-grade stainless steel, ASME B36.19 SCH 80 pipes resist rust, chemical corrosion, and erosion, even when transporting corrosive fluids (acids, alkalis, salts) or gases. This corrosion resistance reduces replacement costs and downtime, making them a cost-effective choice for long-term projects.
Standard Compliance
All our ASME B36.19 SCH 80 pipes are fully compliant with ASME B36.19M (2018) and relevant ASTM standards, ensuring compatibility with global piping systems. Each pipe undergoes strict quality testing (hydrostatic testing, non-destructive testing) to guarantee performance and safety, meeting the requirements of regulated industries.
Customization & Versatility
We offer custom cutting, grooving, and polishing services to match your specific project needs, including custom lengths, surface finishes (2B, BA, polished), and wall thicknesses beyond standard specifications. The pipes are compatible with various connection methods (welding, threading, flanging), making them easy to install in existing systems.
Environmental & Sustainability Advantages
Eco-Friendly Material
Stainless steel used in ASME B36.19 SCH 80 pipes is 100% recyclable, reducing environmental impact and aligning with global sustainability goals. The production process adopts energy-saving and emission-reduction technologies, minimizing carbon footprint. Unlike plastic pipes, stainless steel pipes do not release harmful substances, making them suitable for environmentally sensitive projects.
Energy Efficiency
The smooth inner surface of ASME B36.19 SCH 80 pipes reduces fluid resistance, lowering energy consumption for fluid transportation. The excellent thermal conductivity of stainless steel also helps improve energy efficiency in heat exchange applications, reducing operational costs for customers.
