In 2006, Great Wall HP-R grease was used in the friction parts of high-speed heavy-duty truck axles, steering knuckle pins, and brake systems produced by Dongfeng Dana. After several years of real-vehicle application, the superior performance of the product has been highlighted in high-speed and heavy-duty vehicles, and has been fully recognized by customers. At present, Great Wall HP-R grease has been written into Dongfeng Dana Axle Co., Ltd. product specification. With the development of heavy-duty trucks in high-speed, high-speed heavy-duty trucks, higher requirements have been placed on the lubrication of wheel bearings and body accessories. The high extreme pressure, high temperature, and long-life properties of lubricated products are beyond the reach of ordinary lubrication products. . Great Wall HP-R Grease is a new type of automotive grease developed with the development of the automotive industry. The grease is based on a new type of compound thickener with excellent temperature resistance and refined high-viscosity mineral oil. It is specially processed and added with various additives. Refined, the use of performance in the automotive lithium base grease has greatly improved and improved, more suitable for high-speed heavy-duty vehicle lubrication. Dongfeng Dana Axle Co., Ltd. is the largest subsidiary of Dongfeng Motor Group and is the largest professional, multi-variety, full-series axle production base in China.

The Kra pipe is a thermal winding pipe with a high-density polyethylene structure wall. HDPE winding structure wall pipe is a new type of special-shaped structure wall pipe. It is made through a high-density polyethylene thermal winding molding process. The products are mainly made of high-density polyethylene resin (HDPE) as raw material. The product uses PP or Pe bellows as auxiliary supporting tubes. It is high-density polyethylene large-diameter winding reinforced tubes produced by the thermal winding molding process. It is known as Kra pipe in China because this kind of pipe was originally imported from the German kra company. The official name of the product in China is high-density polyethylene structural wall thermal winding pipe. The national standard is GB/T 19472. 2-2017 B-type structural wall pipe.

1. Municipal water supply and drainage: The internal pressure of high-density polyethylene (HDPE) winding reinforced pipe can reach 12kg/cm2, which is the ideal pipe to replace the original drainage cast iron pipe and cement pipe in the city. The pipe can be used for municipal underground drainage, sewage, rainwater collection, water transmission, ventilation, etc to discharge liquid and gaseous substances into rivers or the sea. Thermal structure wall winding pipe has the advantages of lightweight, safe, reliable connection,corrosion resistance, and high ring stiffness, therefore the use of thermal structure winding pipe has great advantages.
2. Large-scale water conservancy projects: long-distance water transmission, farmland irrigation, reservoir drainage, water source pipe, irrigation pipe and hydropower station water transmission, drainage use;
3. Environmental protection engineering: deep sea sewage, sewage treatment, waste
dump sewage, detoxification pipeline. Due to the thermal structure wall winding pipe of various pipe wall structures and pipe, inspection well, pipe fitting, and its reliable connection performance, the pipe can be used for advanced shallow drainage systems.
4. Petroleum industry: oil, gas pipeline.
5. Coal industry: coal transport, ventilation systems.
6. Chemical engineering: chemical containers, especially corrosive fluid delivery
pipelines.
7. Electric power engineering: circulating water pipeline.
8. Road engineering: crossing roads and railways have a large traffic load of water
culverts and crosswalks; Used as railway and highway road seepage, drainage pipe; The method of "liner in pipe" is becoming more and more important for repairing damaged pipes.
9. The laying of pipes in a corrosive environment.
10. Agricultural engineering: farmland, orchard, tea garden and forest belt irrigation, and so on;
11. Large airport port, wharf engineering: large airport port, wharf engineering drainage, sewage pipe, etc.
12. Construction engineering: building stormwater pipes, underground drainage pipes, sewage pipes, ventilation pipes, etc.
Communication tube: railway, highway communications, communication cables, optical cable protection pipe.
14. Water storage system: used to intercept the slow water storage system.
15. Special application: thermal winding wall winding pipe can also be used for special
purposes such as ventilation, passage, desert, swamp, lake area with fluid transport, etc.
