The high quality surfacing wear steel pipe is composed of low-carbon steel Q235 and Cr28 welding wire surfacing wear-resistant layer. The matrix provides comprehensive properties such as strength, toughness and plasticity against external forces during work, and the Cr28 welding wire surfacing wear-resistant layer provides Abrasion resistance that meets the requirements of specified working conditions.
Our company can produce high-quality surfacing wear-resistant steel pipes according to the drawings provided by customers, which are used for coal feeding pipes, conveying pipes, etc., with high processing accuracy, high wear resistance, high impact resistance, convenient welding performance, High performance and price ratio. Although the surface cost of wear-resistant surfacing pipes is relatively high, considering the service life of the parts, maintenance costs, and downtime losses, the cost performance is about 2 to 4 times higher than that of ordinary steel pipes. Due to the reasonable use of materials, the price of wear-resistant surfacing pipe is 50% lower than that of manual surfacing of the same material.
Technical requirements for high quality surfacing wear steel pipe
Pipe inner diameter: ≥120mm
Surfacing thickness: 2mm
Hardness: 60～62HRC
Operating temperature: ≤600℃
The characteristics of high quality surfacing wear steel pipe
The combination of the wear-resistant layer on the inner wall of the pipeline and the base pipe is a combination of electric welding and metallurgical properties, so it is resistant to impact and vibration, and the wear-resistant layer will never fall off or fall off.
It has the characteristics of excellent welding performance, beautiful welding seam shape, and small welding spatter. There is no need to use gas or flux protection during welding, which simplifies the welding process and saves the cost of welding auxiliary materials. Fine cracks appear during surfacing, which is the result of stress release and does not affect normal use under low-impact industrial and mining conditions.
Use of high quality surfacing wear steel pipe
Widely used in metallurgy, coal, electric power, glass, cement, mining, building materials, bricks and tiles, etc. Compared with other materials, surfacing wear-resistant pipes are relatively cost-effective and have been favored by more and more industries and manufacturers.
