When your project demands toughness and reliability, our 2-inch 304 stainless steel pipe delivers. Seamlessly crafted from premium 304-grade stainless steel, this pipe combines corrosion resistance, high-temperature resilience, and unmatched strength for industrial, commercial, and residential projects.
- Corrosion Crusher: Resists rust, acids, and saltwater – thrives in marine, chemical, or outdoor environments.
- Pressure Pro: Handles up to 1,200 PSI (Schedule 40 and 80 options available).
- Heat Warrior: Stable from -40°F to 1,500°F – perfect for HVAC, steam lines, or exhaust systems.
FAQs
Q: Can I weld 304 stainless steel pipe to carbon steel fittings?
→ Not recommended – use stainless-specific filler rods to avoid galvanic corrosion.
Q: How does 304 compare to 316L for saltwater use?
→ 304 works for mild coastal climates; upgrade to 316L for extreme marine environments.
Q: Do you offer custom cutting or threading?
→ Yes – order exact lengths (1ft to 20ft) with threaded, beveled, or grooved ends.
