Quali sono i materiali per tubi resistenti all'usura e come sceglierli?

I tubi vengono spesso utilizzati per trasportare materiali nei sistemi industriali. They are like the blood vessels of factories. Tuttavia, because materials flow through them, pipe walls can wear down over time. To prevent this, wear-resistant pipes are needed.

Different types of wear-resistant pipes are made from different materials. Each material works best under specific conditions. The main types of materials are explained below.

1. Metal Wear-Resistant Pipes

These pipes are usually made with high-chromium materials. They are used in harsh environments such as:

• High-temperature fly ash pipelines

• Tailings backfill systems

• Coal washing plants

They are strong and reliable. Tuttavia, they are heavy and costly.

Types Offered:
Beijing Naimer provides:

• Cast bimetallic wear-resistant pipes

• Cladding alloy wear-resistant pipes

These are the most common metal options.

2. Ceramic Wear-Resistant Pipes (KNM60)

These pipes are made from silicon carbide E alumina. They are used in high-precision industries, ad esempio:

• Lithium battery production

• Silicon powder handling

• Situations with severe wear

They resist wear well but are expensive and fragile.

Recommendation:
Beijing Naimer uses full ceramic pipes instead of ceramic pieces, as pieces may fall off easily.

3. Ultra-High Molecular Weight Polyethylene (UHMWPE) Pipes

These are plastic-based pipes used mainly for slurry transport.

Vantaggi:

• Basso costo

• Good resistance to corrosion

Limitations:

• Poor high-temperature resistance

• Not suitable for large, dry particles

How to Choose the Right Material?

The pipe material should be selected based on actual working conditions. By choosing the right type, costs can be reduced and production can run smoothly.
