Wear-resistant Steel Pipe

Wear-resistant Steel Pipe Definition

Wear-resistant steel pipe is widely used on electric power, metallurgy, coal mining and chemical industries, conveying sand, stone, mine powder, lime-ash, aluminum liquid and other grindability particles and corrosive media.
Wear resistant steel pipe can be a welded pipe or seamless pipe. And welded wear resistant steel pipe is produce from wear resistant steel plate, they can be ERW pipe, or SAW pipe. Welded wear resistant steel pipe have lower strength compared with seamless pipe. Our production scale for seamless wear-resistant steel pipe is from OD 42 till 508mm, and WT from 4 to 80mm.
We produce the wear-resistant steel pipe as per GB8162, GB8163 and GB33966.
Production Size Range: OD 21.3mm to 630mm x WT 3mm to 80mm
Below table is the mechanical property for our seamless wear-resistant steel pipes.

FAQ

1What kind of wear-resistant pipe is used in mines?
The outer layer is high-strength steel and the inner layer is ceramic, which is called ceramic lined composite steel pipe. The ceramics in the inner layer are very wear-resistant
2Performance characteristics of wear-resistant pipe?
a. Excellent wear resistance, continuous use for more than 10 years.
b. The lining ceramic has high strength, high hardness and light weight
c. Firm mounting, good heat resistance and corrosion resistance
d. The inner wall is smooth and does not block the powder
3What is the classification of wear-resistant pipes ?
There are mainly seven kinds of wear-resistant pipes as follows:
a. Ultra-high molecular polyethylene pipeline, mainly used for slurry transportation; b. Polymer ceramic corrosion-resistant and wear-resistant pipelines are mainly used in desulfurization pipelines; c. Bimetal surfacing alloy wear-resistant pipeline, which is used for pulverized coal transportation pipeline; e. Casting bimetallic high chromium wear-resistant pipes for mine backfilling; e. Integral ceramic wear-resistant pipeline, which is used for conveying pipeline with silicon powder; f. Rubber wear-resistant pipeline, used for corrosive slurry pipeline; g. Cast stone wear-resistant pipeline, used for ash conveying pipeline of power plant;
