Ceramic lined pipe is made through the self-propagating high-temperature synthesis (SHS) technique.
Self-propagating High-temperature Synthetic process
Self-propagating high-temperature synthesis (SHS) is used to describe a process in which the initial reagents (usual powders), when ignited, spontaneously transforms into products due to the exothermic heat of reaction.
The combination of high rigidity of ceramic and high elasticity of steel gives the pipe unmatchable features like abrasion resistant, heat resistant, and corrosion-resistant material for use in the fields of power generation, metallurgy, mining, and chemical industry, etc. It has many advantages over steel pipes, cast stone pipes, and steel-plastic compound pipes.
Usage of Ceramic Lined pipe
The ceramic-lined pipe transportation has been widely used in the industries of electric power, metallurgy, coal, petroleum, chemical engineering, building materials, mechanism, and so on.
The ceramic lined elbow throughout the power, metallurgy, coal, petroleum, chemical, building materials, machinery, and other industries, and high-speed development. When lining the wear-resistant ceramic elbow to deliver high grinding material (such as ash, coal, ore powder, etc.), there is a lining of wear-resistant ceramic elbow wear fast, especially the elbow Wear faster. When lining a ceramic-lined elbow to deliver a highly corrosive gas, liquid or solid, there is a problem that the lined wear-resistant ceramic elbow is corroded and is quickly damaged.
There is a problem that it is expensive to use a heat-resistant steel pipe when the material having a higher temperature is conveyed in the lining of the wear-resistant ceramic elbow. After lining the wear-resistant ceramic elbow, these problems are solved.
The ceramic lined elbow is widely used in wear and tear of mine filling material, ore powder and tailings transportation, coal-fired power plant powder, smelting, ash and other things lined with wear-resistant ceramic elbow are also very appropriate.
The ceramic lined pipe, Elbows, Reducer, Tees, and others manufactured in our factory have been used in over 200 thermal power plants, more than 50 mines, and the industries of coal, building materials, mechanism, petroleum, and so on.

AQE Gate valves are used to limit the flow of fluid flowing straight through the pipeline. This is an effective and reliable way to stop fluid flow. The Slab Gate Valve can be fully opened or fully closed. The slow opening and closing of the valve helps avoid hydraulic hammers, which can damage the pipes connected to the valve. Gate valves are not used for throttling, so do not let them half open. The gate valve has 3 important parts. They are doors, stems and hoods.
The gate can be used in several variations in a gate valve. You may occasionally use knife doors, or if you use crude oil, you may see flat doors. However, in the marine industry, the most common gate is the wedge. This type of gate valve wholesale uses a wedge-shaped metal sheet that can be moved into the valve body to prevent fluid flow. This uses metal-to-metal contact to create a positive pressure seal. However, under extremely low pressure (5 psi or lower), the gate valve may leak a little.
