Product Overview

Nextera Insulations manufactures high-quality Stainless Steel Compression Springs (also called breather springs) that are designed for fastening insulation applications in a high-performance insulation system. Our Compression Springs are specifically engineered to remain tensioned when accounting for thermal expansion and contraction in large diameter insulated and jacketed piping, tanks, vessels, and industrial equipment.

Nextera’s Compression Springs are made from AISI Type 302, 304, and 316 stainless steel which results in superb corrosion resistance, tensile strength, and elasticity. These are used in both indoor and outdoor marine and industrial applications and are used in oil & gas, power generation, marine, and HVAC Industries.

Key Features

• High Compression Capacity – Provides constant clamping force, (up to 80 lbs./inch of compression) clamping force to clamp insulation tight.
• Corrosion Resistant Material – Made from stainless steel (AISI 302/304 and 316) to provide resistance to marine/industrial environments.
• Temperature Tolerance – Works in extremely hot or cold environments without losing elasticity.
• Versatility – Works with stainless steel strapping widths up to ¾” for the greatest versatility.
• Long-Term Cycle Durability/Tension – Maintains tension through many cycles of expansion and contraction.

Technical Specifications

• Material Grades:
  • AISI 302 / 304 Stainless Steel (spring)
  • AISI 316 Stainless Steel
• Strapping Size: ¼” x 0.020″ stainless steel
• Seal Type: ¾” closed seal
• Recommended Installation: One compression spring per 25’ of strapping
• Compression Range: ½” total compression (¼” per spring half)

Applications

Our stainless steel compression springs are widely used to:

• Secure insulation jackets on pipes, tanks, and vessels exposed to temperature variations.
• Maintain consistent strapping tension during thermal cycling in industrial processes.
• Support marine and offshore insulation systems exposed to saltwater and harsh weather.
• Prevent insulation damage from over-tightening by evenly distributing strapping force.

Installation Guidelines

• Feed stainless steel strapping through the spring slots and loop back over the flat bottom plate.
• Secure strapping using a ¾” closed seal.
• Wrap the strapping around the insulated object and repeat the process until the full circumference is secured.
• Install one spring for every 25 feet of strapping.
• Compress each spring to a total of ½ inch to ensure optimal tension without overstressing the system.

Frequently Asked Questions

1. What are stainless steel compression springs used for?

Stainless steel compression springs are designed to fasten and secure insulation jackets on pipes, tanks, vessels, and industrial equipment. They maintain constant clamping force during thermal expansion and contraction, making them essential in oil & gas, marine, power generation, and HVAC applications.

2. What grades of stainless steel are available for compression springs?

Nextera compression springs are manufactured from AISI 302, 304, and 316 stainless steel.

• 302/304: High-tensile strength and corrosion resistance for general industrial applications.
• 316: Marine-grade stainless steel with added molybdenum for superior resistance to chlorides, seawater, and harsh environments.

3. How much compression capacity do the springs provide?

Our stainless steel compression springs provide up to 80 lbs./inch of clamping force, with a ½-inch total compression range (¼ inch per spring half). This ensures insulation remains tightly secured without overstressing or damaging the system.

4. What strapping sizes are compatible with compression springs?

The springs are designed for use with stainless steel strapping up to ¾ inch wide. Recommended installation requires one compression spring for every 25 feet of strapping, ensuring even load distribution and reliable insulation support.

5. Can compression springs withstand extreme temperatures?

Yes. Nextera stainless steel compression springs are engineered to perform in extremely hot and cold environments while maintaining their elasticity and tension. This makes them suitable for cryogenic systems, high-temperature processes, and marine insulation applications
