WDH Series Welded Steel Drag Chain

The welded steel drag chain is a chain designed explicitly for use in material handling and delivery systems. It is a durable chain that can withstand heavy loads and harsh operating conditions. Welded steel tow chains are usually mild steel but can also be made of other materials, such as high-carbon or stainless steel.

The manufacturing process of welded steel drag chains is similar to that of other types of welded steel chains. Individual connections are made of steel wire or steel rods that are cut to the desired length and then bent into the shape of the connection. The joined ends are then superimposed and welded using an arc welding process. The resulting weld is strong and durable, and provides a secure connection between the links.

Once the connectors are welded together, they are inspected for quality and then heat-treated to improve their strength and durability. Heat treatment involves heating the chain to high temperatures and cooling it quickly, which helps align the metal grains and increase the hardness of the chain.

Types Of Welded Steel Drag Chain:

  1. Standard Drag Chain: This general-purpose chain is commonly used in material handling and conveyor systems. Made from low-carbon steel, it is available in various sizes and link configurations.
  2. Heavy-Duty Drag Chain: This high-strength chain is capable of withstanding heavy loads and harsh operating conditions. It is made from high-carbon steel and is heat-treated for added strength and durability.
  3. Drop-Forged Drag Chain: This is a type of drag chain that is made from drop-forged steel, which provides superior strength and durability. The drop-forged drag chain is commonly used in heavy-duty applications such as mining and construction.
  4. Stainless Steel Drag Chain: This type of welded steel drag chain is made from stainless steel, which provides excellent corrosion resistance and is ideal for use in harsh environments. The stainless steel drag chain is commonly used in the food processing and pharmaceutical industries and in applications where cleanliness is essential.
  5. Plastic Drag Chain: This tow chain made of plastic has excellent corrosion resistance and is ideal for use in wet or corrosive environments. Plastic tow chains are commonly used in sewage treatment and chemical industries.

How To Maintain Welded Chain?

Keep the chain clean: Dirt, dust, and debris can cause wear and tear on the chain, so it’s important to keep it clean. You can use a wire brush or cloth to remove any dirt or debris that has accumulated on the chain.

Lubricate the chain: The chain needs to be lubricated to prevent rust and corrosion, reduce friction, and keep the chain running smoothly. You can lubricate the chain using a lubricant specifically designed for the chain, such as chain oil.

Check the chain regularly: Regular inspections can help you identify any wear or damage to the chain before larger problems develop. Look for signs of wear, such as elongation, bent or broken links, or rust and corrosion.

Replace damaged or worn chain: If you notice any damage or wear on the chain, replace the chain as soon as possible. Damaged or worn chains may break, which can be dangerous and cause damage to the equipment.
