Product Introduction
1-2 Inch (inch) stainless steel pipes are widely used hollow profiles in both industrial and civil fields. The outer diameter ranges from 25.4mm (1 inch) to 50.8mm (2 inches).
Due to the inherent corrosion resistance, high strength, and easy processing characteristics of stainless steel, they can be adapted to various complex working conditions and have both structural support and medium transportation functions. They are core basic components in industries such as mechanical manufacturing, fluid engineering, and architectural decoration.

Key Features
Long service life & lower total cost
Outstanding corrosion resistance stands up to a wide range of media, lasting 5–10 times longer than carbon steel pipes, greatly cutting down on replacement and maintenance expenses over time.
High strength & stable performance under extreme conditions
Tensile strength of 480–620 MPa supports high-pressure systems, while reliable operation from -20°C to 500°C ensures consistent performance in harsh environments.
Precise fit for easy installation
Tight, controllable dimensional tolerances work with multiple connection types, simplifying on-site assembly and meeting complex project requirements.
Hygienic & low-maintenance design
Non-porous, smooth surface complies with food and pharmaceutical grade standards, making cleaning and daily upkeep fast and hassle-free.
Flexible selection for real-world projects
A full range of material and pipe specifications lets you balance performance and budget, adapting to diverse working conditions and application scenarios.
