What Steel pipe is suitable for pulverized coal conveying?

There are two ways to choose pulverized coal conveying, that is, the use of pulverized coal cans dedicated trucks or the use of pipe pneumatic conveying, and pneumatic conveying a good continuity, capacity and good sealing, is the most commonly used in blast furnace pulverized coal conveying mode. According to the difference of powder gas ratio μ, pipeline pneumatic conveying is divided into dense phase conveying (μ>40 kg/kg) and dilute phase conveying (μ=10-30 kg/kg). Dilute phase conveying is widely used in China.

Because of its extremely high hardness and scaling resistance, its resistance to wear the first pipe, than bimetal, shell nets, surfacing 6 times times, nylon, PTFE 10 times times, 15 times times as carbon steel. It is an ideal wear-resistant conveying pipe, which can save energy and prolong the service life of pipelines.?-

Coal industry conveying pulverized coal, mineral powder, tailings, pulp pipe for many pipes, as these media contain about 30% of iron ore, the wear of steel pipe is very strong, the General Service life of the steel pipe for six months to year. Conveying washing solid liquid mixture: coal mining and mineral processing slurry conveying pipeline has tailings pipe, concentrate pipe and so on. Coal preparation plant to transport the mixture of flotation, flotation concentrates and heavy medium suspensions, such as solid-liquid mixtures, steel pipe use 16 months wear, and the annual cost of costly maintenance.

Self-propagating technology makes the ceramic liner composite Steel pipe has a unique structure, which determines the excellent physical and mechanical properties of ceramic steel pipe, it not only abrasion resistance, corrosion resistance, high temperature, but also has high hardness, strength and good resistance to mechanical impact and thermal shock of the comprehensive performance.

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.
