High-Quality Stainless Steel Pipe & Tube for Industrial Use
Welded and seamless stainless steel pipes in 304, 316L, and other grades for construction, fluid transport, and structural applications.
What Are Stainless Steel Pipes & Tubes?
Stainless steel pipes and tubes are long, hollow sections used for fluid transport, structural support, or decorative use. They are valued for their corrosion resistance, durability, and clean finish.
The key difference:
Pipes are generally used for transporting fluids or gases (focus on pressure & internal diameter)
Tubes are often structural or decorative (focus on outer dimensions & finish)
Available in round, square, and rectangular shapes and used in construction, chemical plants, marine structures, furniture, and mechanical systems.

Frequently Asked Questions
Q1: What’s the difference between seamless and welded pipes?
A:
Seamless pipes have no weld seam and are used for high-pressure and critical applications. Welded pipes are more economical and suitable for general use.
Q2: Do you offer decorative pipes with mirror finish?
A:
Yes. We supply tubes with mirror (8K), brushed (No.4), and hairline finishes for decorative applications.
Q3: Can stainless pipe be used outdoors?
A:
Yes. Grades like 304 and 316 are suitable for outdoor use, especially 316 for marine or coastal environments.
Q4: What is the tolerance for OD and wall thickness?
A:
Standard tolerance applies per ASTM A554 / A312, and tighter tolerances available upon request.
Q5: Can you do custom lengths or perforated tubes?
A:
Absolutely. We support CNC cutting, perforation, and slotting per customer drawings.
