What kind of wear-resistant pipes are generally available?
There are many types of wear-resistant fittings. Self-propagating composite ceramic tube, wear-resistant ceramic patch tube, bimetallic wear-resistant tube, high-temperature wear-resistant turtle mesh tube, high-strength rare earth wear-resistant alloy steel cast tube, rubber-lined composite steel tube, wear-resistant backpack composite tube and so on. The characteristics and applicable scope of different types of wear-resistant pipe fittings are different. It should be customized according to its working conditions and technical requirements.
Because the tube has wear resistance, corrosion resistance and heat resistance, it can be widely used in electric power, metallurgy, mining, coal, chemical and other industries as conveying abrasive materials such as sand, stone, coal powder, ash and aluminum liquid. And corrosive media, is an ideal wear-resistant pipe.
At present, dozens of thermal power plants have shown that the lining ceramic wear-resistant steel pipe has high anti-wear ability and strong anti-fluid scouring ability. In a single air duct, the elbow wears the fastest, and the wear resistance of the inner-lined ceramic wear-resistant steel pipe bend is more than 5 times higher than that of the thick-wall wear-resistant cast steel bend.
In practice, the lining ceramic wear-resistant steel pipe is opened and observed and measured after 1-2 years. The composite layer has no obvious wear or shedding. In the same specification and unit length of the pipe, the lining ceramic wear-resistant steel pipe only has the resistance. About 1/2 of the milled steel pipe or bimetal composite pipe, the engineering cost per meter is reduced by 30-40%, only about 2/5 of the weight of the cast stone pipe and the rare earth wear-resistant steel pipe, and the engineering cost per meter is reduced by more than 20%. . Lining ceramic wear-resistant steel pipes used in corrosive or high-temperature places, the price is only a fraction of that of stainless steel pipes and nickel-titanium pipes.
