Corrosion-Resistant Chains: Essential for Marine and Chemical Operations

In some industries, exposure to moisture, harsh chemicals and extreme environmental conditions are unavoidable. In such settings, the utilisation of corrosion-resistant machinery and components is paramount. For example, both the marine and chemical industries rely on corrosion-resistant chains that can withstand constant exposure to salt water, acids, and other corrosive substances.

At John King Chains, we specialise in manufacturing a wide range of high-quality conveyor chains and sprockets, including corrosion-resistant chains that are specifically designed to excel in these challenging environments. Opting for conveyor chains that have been crafted with the right materials and coatings can help businesses improve the efficiency, safety, and longevity of their operations.

Why does corrosion resistance matter?

Corrosion can represent a significant challenge in marine and chemical applications. It can lead to:

• Structural weaknesses: Rust and corrosion weaken equipment, including chains, increasing the risk of failure.
• Reduced lifespan: Without adequate protection, chains can degrade quickly, leading to the need for frequent replacements.
• Increased maintenance costs: The need for more regular repairs and replacements increases downtime and associated expenses.
• Safety risks: Corroded chains can break under load, posing significant safety risks to workers and equipment.

Choosing corrosion-resistant chains ensures durability, reliability, and cost-effectiveness in harsh operating conditions.

Industries that require corrosion-resistant chains

A number of industries require conveyor chains and other equipment that can withstand corrosive environments. These include:

• Marine and offshore operations – Such as ship-building, docks, oil rigs, and fishing vessels. Equipment must resist saltwater corrosion and extreme weather conditions.
• Chemical processing – Facilities that handle corrosive substances such as acids and alkalis need chains that can withstand chemical exposure.
• Pharmaceutical and medical – Sterile environments require equipment that can withstand harsh cleaning chemicals.
• Food and beverage – Chains used in food production settings must be resistant to moisture, cleaning agents, and good-grade sanitisers.
• Water treatment – Chains that are continuously exposed to moisture and chemicals, such as in sewage treatment plants, must be highly resistant to corrosion.

What are the Best Materials for Corrosion-Resistant Conveyor Chains?

Choosing the right materials is essential in preventing corrosion. Some of the best options include?

Stainless Steel Chains

Stainless steel is highly resistant to moisture, including salt water and most chemicals. This makes it an ideal material for marine, food processing, and pharmaceutical industries where strength and longevity are required.

Nickel-Plated Chains

Nickel offers enhanced corrosion resistance which makes nickel-plated chains a suitable solution for moderate chemical and moisture exposure. These chains are often used in chemical plants and manufacturing environments.

Zinc or Epoxy Coated/Plated Chains

Zinc-plated chains provide moderate corrosion resistance while epoxy coatings add an extra protective barrier against harsh chemicals. These chains can be used in outdoor and semi-corrosive environments.

Plastic and Polymer Chains

Non-metallic, plastic and polymer chains are fully resistant to corrosion. They are lightweight yet strong, making them ideal for chemical processing and conveyor systems. Plastic chains are a great solution for low-load applications in corrosive settings.
