In the electric power, metallurgy, chemical industry, mining, cement, paper-making and other industries, because the conveying medium for conveying equipment wear-resistant requirements are relatively high, ordinary steel pipe cannot meet the actual use needs, which requires better wear-resistant conveying equipment.
For different production environments, our company has developed a wear-resistant pipe for a variety of media, based on the temperature, wear and corrosion requirements of the field media, and for the initial application of the scene, our company to provide wear-resistant ceramic ring for the Lined composite straight pipe design to meet the on-site wear resistance, heat resistance and corrosion resistance requirements, in view of this program for the new design (formerly ceramic chip technology, there are many gaps, easy to wear).
After the ceramic ring in the pipe is installed and the thread is processed, the dirt outside the pipe is cleaned, and the outer surface of the pipe is treated with three layers of anticorrosive paint to meet the export requirements.
Abrasion resistant pipe using steel skeleton packaging, and the two ends of the pipe with plastic head, to prevent dust and rain into the pipeline inside, to ensure the beauty of the product.
The wear resistant ceramic ring is a special kind of ceramic with Al2O3 as the main raw material and the rare metal oxide as the flux, which is melted by high temperature at 1700 oC.
1. The wear-resistant ceramic ring has the characteristics of smooth interior wall and super wear resistance. Widely used in chemical, fine powder conveying pipelines and other industries, with high wear-resistant and anti-corrosion functions.
2. In accordance with the traditional process, the production of wear-resistant ceramic ring is mainly the use of hot-pressing casting or grouting molding. Adopting isostatic pressing forming technology, the ceramic ring with isostatic pressing is better in compactness and more accurate in ceramic size.
3. At present, our ceramic ring lining pipeline in the silicone industry, chemical industry, fine powder conveying industry has been widely used.

Conveying highly abrasive materials, steel piping systems are under constant attack often over long distances.
Because the outer surface behaves like mild steel, the product can be cut and welded with proper procedure in the field, configured into a variety of fittings, and can accept the standard end options of flanges, weld rings and couplings.
Warranty
We are Quality Department tests and ensures all of our products are 100% inspected unreported. To an offer we customers additional corps of mind, all our products carry a 24-month warranty against defects or faulty workmanship.We fluid-flow products such as pipe and fittings, chokes, orifice plates, etc, carry a warranty against, erosion, defects, and/or faulty workmanship.
The warranty is determined to each creator and the maximum duration maximally in service. Should any of the RS fail within the warranty period, We'll replace or repair the defective product (s) at No. end user. Please contact the Sunny steel for details on the How to obtain a warranty for our products.
