Wear resistant ceramic elbow, ceramic wear resistant elbow

Pneumatic ash conveying ceramic wear-resistant elbow.

1. Production process:

The self-propagating ceramic composite steel pipe is made by self-propagating high-temperature centrifugal synthesis process. The tube is composed of corundum ceramics, transition layer and steel body from the inside to the outside, the ceramic layer is a dense corundum porcelain formed by a high temperature of more than 2200 degrees, and a strong bond is formed with the steel pipe through the transition layer.

The process is formed by the method of self-propagating centrifugal casting, which mainly uses the chemical reaction of the substance itself, exothermic combustion to produce high temperature, and synthesizes new substances in the process of combustion wave propagation.

2. Performance characteristics:

Good wear resistance, the inner lining layer is corundum porcelain (Al2O3), Mohs hardness is equivalent to HRC 90, so it has high wear resistance to any medium conveyed by electric power, metallurgy, mining, coal mining and chemical industries, and its service life is more than 10 times that of ordinary steel, because the inner lining layer corundum porcelain (Al2O3) is a single stable crystal structure, so it runs for a long time in the temperature range of -50 600, the material line expands 6 8 10-6, and the inner surface of the composite steel pipe is smooth, and the running resistance is small, It has comprehensive properties such as anti-corrosion and anti-scaling, good welding performance, and can be connected by direct welding, flange connection, quick pipe joints, etc., and the construction and installation are very convenient.

If you want to ask the manufacturer of wear-resistant ceramics, you can find Hebei Jiutong, if you want to ask the type of ceramics, you can have self-diffuse combustion ceramics, patch ceramics, ceramics are divided into 95 porcelain, 90 porcelain, 85 porcelain, etc. according to the content of aluminum oxide. If it is, it depends on what kind of ceramic elbow you want. The patched ones are more expensive than the self-diffuse ones.

Hope it helps.

Technical requirements for pneumatic ash conveying pipelines and wear-resistant ceramic elbows.

1. The ash pipeline and pipe fittings adopt the mature self-propagating high-temperature synthesis (SHS) centrifugal casting SIO2 composite wear-resistant lining process, and the wear-resistant pipe is composed of three layers of silica wear-resistant layer, transition layer and steel pipe base from the inside to the outside, and the silica is a dense layer formed at a high temperature above 1730, and a firm metallurgical combination is formed with the steel pipe base through the transition layer.

Its main ingredients:

Silicon dioxide 80% + aluminum oxide 10% (layer), thermite (iron red and aluminum powder mixture), iron flux, Q345D (base layer).

2. The inner surface of the ash pipeline and pipe fittings should be smooth and smooth, and the roughness of the inner surface should not affect the flow rate and output of the conveying medium, so as to ensure that the running resistance is small, and the surface of the inner wall is not adhered to, not scaled, no ash accumulation, and no ash blockage. Cracks and any defects that affect the performance of slag inclusion, sand inclusion, cold separation, porosity, shrinkage porosity, lack of meat, burrs, burrs, sand sticking and other defects that affect the performance are not allowed.

3. The wear-resistant layer should be uniform, complete and dense to ensure that there is no cracking, no falling off and no wear rate during the service life.

4. Ash pipeline and pipe fittings material: Q345D (base layer) + SiO2 (layer), specifications: 325 14 (base thickness 10mm + layer thickness 4mm), 133 10 (base thickness 6mm + layer thickness 4mm), 76 10 (base thickness 7mm + layer thickness 3mm), 108 12 (base thickness 8mm + layer thickness 4mm).

In order to reduce the leakage points of welds and static seals installed in the field, all straight pipe sections are 6m.

5. The thickness deviation of ash pipes and pipe fittings, the roundness of the pipe and the outer diameter), the curvature, the end face of the pipe and pipe fittings are smooth, and the end faces at both ends of the steel pipe should be perpendicular to the axis of the steel pipe.

6. Special-shaped elbows, tees, reducers and other pipe fittings need to be surveyed and mapped on site, and the elbows, tees and their paired straight pipe sections are all connected by TG (tongue and groove surface sealing) flanges; The rest of the straight pipe section is the welded end, and the connecting end is prefabricated with a groove to ensure good welding performance.

Ceramic wear-resistant elbow is installed on the inner wall of the pipeline in the form of pasting or stud welding, forming a firm anti-wear and corrosion-resistant layer, especially in the part where the elbow erosion and wear is very serious, the ordinary elbow can not withstand such serious impact and corrosion, the use time is even less than a year to replace, wasting a lot of manpower and material resources, wear-resistant ceramic elbow with its super wear resistance and corrosion resistance in the pneumatic conveying and hydraulic conveying system of industrial enterprises has been widely used. This product is widely used in the pasting of wear-resistant ceramic sheets, especially in thermal power, steel, smelting, machinery, coal, mining and other industries that have suffered from strong powder erosion or slurry erosion and serious wear and tear of equipment pasting wear-resistant ceramic sheets. It is especially suitable for the pasting of wear-resistant ceramic sheets under high temperature conditions.

This is the wear-resistant performance of the material is still good, mainly there are two kinds of ceramic sheets and wear-resistant ceramic coatings.

The wear-resistant ceramic elbow is to use our company's special temperature-resistant super glue to paste the special corundum wear-resistant ceramic sheet inside the steel pipe elbow, which solves the problem of serious wear and tear of the conveying elbow part of the thermal power, metallurgy, steel, cement and other industries, and adopts the comprehensive solution of the steel pipe elbow and wear-resistant ceramic sheet pasting, which is convenient for rapid replacement and construction.

According to the different working conditions, the production process is also different, and the direct paste method, bolt clamping method or integrated molding method can be used.

Among them, the integrated pipe forming method (RHS) uses selected alumina particles, fires the lined pipe with various molding methods, and then pours the integrated pipe inside the steel pipe with special filler. The pipes formed by this method are different from the ceramic composite pipes formed by the self-ignition technology, and the ceramic crystals lined with ceramic are exactly the same as those of SMD ceramics. Its advantages are that the inner wall of the pipeline is smooth, and it has very good wear resistance, which is suitable for slag conveying and ash removal systems with high requirements for pipeline materials.

The bolt clamping method is a ceramic assembly method that adopts adhesive pasting, ceramic sheets are pressed and interpolated with each other, and bolts are clamped and clamped. Thanks to the triple fixation method, the ceramics and the device have become one, and the ceramics will not fall off even when operating at high temperatures above 1000 °C.

Wear-resistant elbow purchasers do not understand the specifications and models of wear-resistant elbows, as a wear-resistant elbow manufacturer to explain the wear-resistant elbow models in detail, you can learn more about the basic knowledge of wear-resistant elbows.

Wear-resistant elbow materials include corundum ceramic, high-chromium wear-resistant steel, high-temperature tortoiseshell mesh, etc. Wear-resistant elbows need to be designed according to the actual working conditions.

2. Explain the wear-resistant elbow model in detail, including angle, bending radius, steel pipe thickness, and ceramic thickness. For example, 90° wear-resistant elbow DN150*8 R=1000 ceramic thickness 4mm 26 pieces. The angle of the elbow is 90 degrees, and there are 60 degrees, 45 degrees, and 30 degrees, the diameter of the elbow is 150mm, and the thickness of the elbow is 8mm, and the r represents the bending radius of the elbow 1000mm, and the thickness of the lining ceramic is 4mm.

This kind of ceramic elbow is designed with an outer diameter of 180mm, and cannot be designed with a diameter of 159mm, which cannot ensure the diameter.
