In high-temperature industrial settings, the structural stability and efficiency of refractory linings depend heavily on the quality of the anchoring system. One of the most reliable and widely used solutions is the SS 310 V Shape Zig Zag Anchor. This blog explores its design features, key benefits, and where it is most commonly applied.

What is an SS 310 V Shape Zig Zag Anchors?

The SS 310 V Shape Zig Zag Anchor is a specially designed metallic anchor made from Stainless Steel 310, used to secure refractory linings to the internal shell of furnaces, kilns, reactors, and other heat-intensive equipment. The V shape provides structural support, while the zig-zag profile increases surface area and mechanical interlock with the refractory material.

This design not only enhances the holding strength but also reduces the chances of refractory material detachment or cracking during thermal expansion and contraction.

Material Advantage: Why Choose SS 310?

Stainless Steel 310 (UNS S31000) is an austenitic alloy known for its outstanding resistance to high temperatures and oxidation. It is composed of approximately:

• Chromium: 24–26%

• Nickel: 19–22%

• Iron: Balance

These properties make SS 310 ideal for environments where the anchor must withstand:

• Extreme temperatures (up to 1100°C)

• Thermal cycling

• Oxidizing and carburizing atmospheres

• Corrosive industrial conditions

Design Features of V Shape Zig Zag Anchors

• V Shape: Offers balanced support and flexibility under thermal stress.

• Zig Zag Pattern: Enhances mechanical bonding with the refractory material, preventing slippage and detachment.

• Customizable Geometry: Available in various sizes, thicknesses, and angles to suit different lining thicknesses and application requirements.

Key Benefits

Superior Heat Resistance

SS 310 maintains its strength and structure even at elevated temperatures.

Improved Mechanical Bonding

The zig-zag design creates a strong grip between the anchor and the refractory lining.

Minimized Refractory Failure

By allowing thermal movement and reducing stress points, it extends the service life of linings.

Corrosion and Oxidation Resistance

Ideal for both oxidizing and mildly reducing environments in industrial settings.

Easy Installation

Suitable for welding or stud-welding, depending on equipment design and site requirements.

Industrial Applications

The SS 310 V Shape Zig Zag Anchor is extensively used across multiple industries where thermal and mechanical stress is high:

• Petrochemical Plants – Furnaces, reformers, and reactors

• Power Generation – Boilers, incinerators, and heat recovery units

• Cement & Lime Kilns – Rotary kilns, preheater towers, and calcining zones

• Steel & Foundries – Soaking pits, reheating furnaces, ladles, and tundishes

• Waste Management – Incinerators and ash handling systems

Customization Options

Manufacturers typically offer custom fabrication for:

• Leg length and angle

• Material thickness

• Coating options (if needed for extreme chemical exposure)

• Welding compatibility

Conclusion

The SS 310 V Shape Zig Zag Anchor is a critical component in modern refractory lining systems. Its robust design and high-temperature performance make it an industry standard in demanding thermal environments. By choosing the right anchoring system, industries can enhance the safety, durability, and performance of their refractory installations.
