Stainless Steel Pipes
Stainless steel pipes, including round, square, and rectangular types, are essential in diverse industries, with mainstream grades 201, 304, and 316L (316L excels in corrosion resistance for harsh environments). Their core advantages lie in strong corrosion resistance, high tensile strength, and good ductility—able to withstand pressure, moisture, and temperature fluctuations. They're also easy to cut, weld, or bend for customization, with sleek finishes (2B, brushed, mirror) blending functionality and aesthetics, boasting a longer service life than carbon steel pipes.
Applications span sectors: construction uses them for curtain wall supports and handrails; fluid transport relies on them for water, oil, or chemical pipelines (316L for corrosive fluids); machinery manufacturing employs them as equipment frames; kitchen & bathroom areas use them for sink drains and towel racks; municipal projects adopt them for street light poles and drainage systems.
Installation requires pre-treatment—degreasing and derusting the surface. Connection methods depend on scenarios: welding for high-pressure pipelines, threaded joints for easy disassembly, and flanges for chemical systems to prevent leaks. Post-installation, seal joints and clean residues promptly.
Maintenance is straightforward: clean with neutral detergent daily; remove minor rust with specialized removers then re-passivate; check connections quarterly for tightness. Store in dry, ventilated areas to avoid moisture-induced rust, ensuring long-term reliable performance.
