Abrasion resistant pipe

Classification and designation of wear-resistant pipes for power industry

The abrasion pipe of thermal power plant is mainly conveying raw coal powder, ash slag, flue gas desulfurization (FGD) limestone powder and slurry, due to the transmission of medium velocity fast, poor operating conditions, resulting in pipelines, especially elbow, variable diameter pipe serious wear and corrosion, not only consumes a lot of metal materials, but also to the thermal power plant security, economic operation has brought hidden dangers. The abrasion mechanism of pipeline is mainly based on erosion wear.

Wear-resistant pipe can be divided into two categories: single metal pipe and composite pipe.


Abrasion resistant Straight pipes be Long-term use in power plants

Abrasion resistant pipe elbows be Long-term use in power plants

Pipe elbows be Long-term
use in power plants

Because the outer surface behaves like mild steel, the product can be cut and welded with proper procedure in the field, configured into a variety of fittings, and can accept the standard end options of flanges, weld rings and couplings.

Abrasive Applications

One-hundred-twenty-nine-million tons of coal ash—a byproduct of the coal burning process—is produced every year. Most power plants transport the coal ash in liquid form to large surface impoundments or in solid form at landfills near the facility through long lengths of steel piping, which can range in length from several thousand feet to miles.
