Welding Wear Resistant Elbow Impact Resistance For Pulverized Coal Pipe

Product introduction

Wear-resistant ceramic-lined elbows are used in pulverized coal conveying pipelines in thermal power plants, where pipe bends are exposed to continuous abrasion from high-velocity coal particles.

Compared with straight pipe sections, elbows often experience more concentrated wear because the material flow changes direction and repeatedly impacts the outer arc of the bend. Wear protection at these locations is therefore important for reducing pipeline maintenance and unplanned replacement.

This product uses a steel elbow combined with a wear-resistant alumina ceramic lining. The ceramic tiles can be bonded, mechanically fixed, or welded to the steel body, depending on the operating temperature and working conditions.

Pipe diameter, elbow angle, bending radius, ceramic thickness, and connection type can be customized according to the approved drawing.

Product Features

Wear-resistant ceramic lining
95% alumina ceramic tiles provide a hard, wear-resistant surface for pulverized coal and other abrasive powder conveying applications.

Secure fixing structure
Depending on the operating conditions, ceramic tiles can be installed using high-strength adhesive together with mechanical or welded fixing methods to improve lining reliability.

Welded ceramic design
Ceramic tiles with fixing holes can be secured to the steel body using weldable steel components, helping reduce the risk of ceramic detachment in demanding operating conditions.

Reinforced wear area
For elbows with concentrated wear, the lining thickness or ceramic arrangement can be adjusted around the high-wear outer arc according to the project drawing.

Customized connections
Welded ends, flanges, and other connection structures can be supplied according to the existing pipeline system.

Product parameters

Product advantages

Wear protection for critical pipe bends
The ceramic lining protects areas where abrasive particles repeatedly impact the elbow surface.

Reliable ceramic fixing
Bonding and mechanical or welded fixing methods can be selected according to temperature and operating conditions.

Customized reinforcement
High-wear areas can be reinforced through ceramic thickness and lining layout without unnecessarily increasing the lining thickness of the entire elbow.

Flexible connection
The elbow can be supplied with welded ends, flanges, or other customized connections.

Designed for pulverized coal conveying
The product is suitable for coal powder, fly ash, and other abrasive pneumatic conveying systems.
