Seamless Stainless Steel Tubing

The strength and corrosion resistance afforded by our seamless stainless tubing is widely used in instrumentation and heat exchanger tubing for applications in extreme environments.

Seamless Nickel Alloy Tubing

For the utmost in corrosion resistance and reliability in sustained heat, seamless nickel alloy tubing offers consistently high performance in aggressive operating conditions.

Welded Stainless Steel Tubing

Welded stainless steel tubing provides a cost-effective alternative to seamless tubing with the same mechanical and physical properties for long-term performance applications.

Welded Nickel Alloy Tubing

As a cost-effective alternative to seamless tubing, welded nickel alloy tubes provide the same performance specifications in high-stress environments for an optimal value.

Key Characteristics of Seamless and Welded Tubing

The welded and seamless varieties of stainless steel and nickel alloy tubing offer unique characteristics best suited for specific applications.

Seamless Stainless Steel Tubing

  • No Weld Seam: The uniform structure throughout the tube wall provides maximum pressure integrity.
  • Excellent Corrosion Resistance: Performs well in aggressive media and elevated temperatures.
  • Superior Pressure and Fatigue Performance: Seamless stainless tubing is preferred for critical service, high-pressure, and cyclic-load applications.
  • Tight Dimensional Control: Supports precision instrumentation, aerospace components, and use in heat exchangers.
  • High Purity and Cleanliness: Ideal for nuclear, pharmaceutical, and industrial environments.

Welded Stainless Steel Tubing

  • Superior Value Alternative to Seamless: Delivers your required performance specifications at an optimized price point.
  • Consistent Mechanical Properties: Advanced welding and cold working create repeatable tube-to-tube performance.
  • Wide Size Availability: Welded stainless tubing is well suited for larger diameters and custom dimensions.
  • Excellent Corrosion Resistance: Welded stainless delivers comparable performance to seamless tubing in many corrosive applications.
  • Value-Added Processing Options: We offer cold drawing, bead working, and NDT for our welded stainless tubing to enhance performance reliability.

Seamless Nickel Alloy Tubing

  • Exceptional Corrosion Resistance: Designed for highly aggressive chemicals and extreme service environments.
  • High-Temperature Strength: Maintains mechanical integrity in conditions beyond the performance limits of stainless steel tubing.
  • Superior Pressure Capability: Seamless construction minimizes risk in critical service applications.
  • Resistance To Stress Corrosion Cracking and Pitting: Seamless nickel tubing is ideal for heat exchangers, condensers, and instrumentation applications.
  • Long-Term Reliability: Our nickel alloy tubing supports extended service life in demanding industrial and energy applications.

Welded Nickel Alloy Tubing

  • Value-Optimized Performance Upgrade Over Stainless Steel: Welded nickel alloy tubing provides maximum value and higher corrosion resistance than stainless steel tubing.
  • Controlled Dimensional Accuracy: Welding and cold working enable tighter tolerances and greater availability of custom sizes compared to seamless tubing.
  • Strong Corrosion Resistance: Suitable for harsh chemical processing and elevated-temperature service.
  • Consistent, High-Integrity Welds: Engineered for repeatable performance in critical environments.
  • Design Flexibility: Welded nickel tubing supports engineered solutions where seamless tubing may be cost- or size-prohibitive.
