Since the inorganic binder and welding process are used as the connection method between the ceramic and the steel pipe, the elbow can withstand the greater impact force generated by the material and be used under higher temperature conditions.
The alumina ceramics produced by our company are made of high-purity, ultra-fine, single and narrow particle size, high-quality alumina powder treated by spray drying and granulation as raw materials, scientific formula component design and optimized sintering process. The green body only needs to be sintered at a temperature of 1520°C to make the material fully dense, and the lower sintering temperature ensures that the material has a fine-grained structure and solves the problem of deformation.
According to the size of the alumina ceramic product, the molding process of the batch of freebies can be done by dry pressing, isostatic pressing, casting and hot die casting. For this, the pipeline ceramics are made by high-pressure powder pressing by a large-tonnage press. Guaranteed china has the following advantages:
(1) The green body has high pressing density and uniform distribution.
(2) High dimensional accuracy,
(3) It is easy to be mass-produced on a large scale, and the preparation cost is low.
Service life: 5 years for straight pipe packages and 3 years for curved pipe packages under normal conditions.
The alumina ceramic material is selected with high hardness and good wear resistance. The large thickness ceramic block is used as the lining, and the thickness of the lining ceramic layer has two specifications of 4-25mm, which is much larger than the thickness of 3mm and 5mm of the ceramic layer of the general small ceramic sheet and the centrifugal composite casting pipe, so the service life is very long. Under normal working conditions, the service life of the lining with a thickness of 15mm can reach more than 15 to 20 years, and the service life of the lining with a thickness of 25mm can reach more than 30 years.
Easy to install
The outer steel shell (material: Q235, thickness of 6-12mm) is lined with a ceramic layer, and the elbow structure is a shrimp joint. The port connection form can adopt various forms according to different design requirements. The elbow has the advantages of light weight, small volume and on-site construction. Good solderability and other advantages
