Using Lightweight Plain Chains to Remove Blockages in PVC Pipes

When it comes to pipe cleaning, not every tool is suitable for every material. PVC pipes, in particular, need a gentler approach compared to clay or metal pipes. This is where lightweight plain chains come in.

What Are Lightweight Plain Chains?

Lightweight plain chains are specially designed cleaning attachments used with flexible shaft machines. Unlike heavy-duty chains, which are thicker and intended for larger shafts, lightweight chains are much lighter.

This makes them ideal for use with smaller shafts:

• 6mm shafts
• 8mm shafts

By comparison, heavy-duty chains are usually used on 10mm or 12mm shafts.

Why Use Plain Chains in PVC Pipes?

PVC is softer than metal or clay, so aggressive cutting tools with tungsten carbide bits can easily damage the pipe. Plain chains, however, do not have cutting tips. They are designed to:

• Clean the inner surface of the pipe
• Remove blockages such as grease, scale, or soft debris
• Preserve the pipe material by minimizing wear and preventing damage

Different Chain Configurations

Lightweight plain chains come in various setups depending on pipe diameter and application:

• Single-chain setup for smaller pipes
• Double or triple-chain setups for larger pipes
• With or without a drill head, depending on the type of blockage and your preference

There’s also a mini version, which acts as a hybrid between a circular chain and a standard chain—perfect for versatile cleaning in narrow PVC pipes.

Key Takeaways

• Use lightweight plain chains for cleaning PVC pipes.
• Match the chain to the shaft size (6mm or 8mm).
• Choose the right configuration (single, double, triple, or mini).
• Avoid tungsten carbide bits in PVC, as they are aggressive and intended for metal or clay pipes.

Selecting the right chain ensures your PVC pipes stay clean and free of blockages without risking damage.
