On December 2, 2010, Weichai Group's 2011 business conference was held in Jinan. Weichai expects that the production and sales of various engines will exceed 750,000 units in 2010, an increase of 102% year-on-year; sales revenue will reach 45 billion yuan, ranking the world's highest speed High-power engine supplier status.
It is understood that in the next five to ten years, the Weichai Group must become an international enterprise group that is guided by complete vehicles and complete machines and whose power has always been a core technology, and has developed into an extremely important global equipment manufacturing industry. According to the strategy of the Weichai Group, it will achieve 150 billion yuan by 2015 and 200 billion yuan by 2020.
From January to November 2010, Weichai Group achieved a sales income of 81 billion yuan, a year-on-year increase of 63%, and a profit and tax of 11.5 billion yuan, a year-on-year increase of 98%. It is expected that sales revenue for 2010 will exceed 85 billion yuan. It is expected that by 2011, the Weichai Group's annual operating revenue will exceed the 100 billion mark, and the expected target will be achieved two years ahead of schedule, of which the engine production and sales volume will exceed one million units.
The industry analysts believe that in the next 10 years, China’s domestic demand for large and medium-displacement diesel engines will continue to be high, which provides a favorable market environment for Weichai’s engine business. Moreover, the domestic heavy-duty truck market is still expected to have more room for growth. At present, the domestic heavy-duty truck capacity has reached 1.5 million vehicles, and it is estimated that by the end of the 12th five-year plan, this figure will exceed 3 million vehicles.
Tan Xuguang said that the Weichai Group will actively carry out structural adjustments in the future to balance the development of powertrains, commercial vehicles, and parts and components. Among them, the engine business segment should be built into a global leading, full-range, full-field power provider, and build a million-dollar, one-billion-level green power R&D and manufacturing base. Weichai Group's product displacement will cover 2-620L and its power will cover 30-10000 hp. It will be widely used in commercial vehicles, construction machinery, passenger cars, ships, yachts, power generation, agricultural machinery and other fields, and strive to achieve sales revenue of 50 billion yuan in 2012. Yuan reached 80 billion yuan in 2015 and 100 billion yuan in 2020. Its overall strength ranks among the top two in the global engine industry and it challenges the world's first.
Since the 11th Five-Year Plan, Weichai Group has accumulated 37 new product developments, and has successively successfully developed a high-power, high-speed diesel engine with complete independent intellectual property rights that meets the National III, National IV, and National V emission standards in China. The main technical indicators and international Advanced horizontal connection. During the 12th Five-Year Plan period, Weichai Group has initially planned more than 10 billion yuan for technology research and development.
The flat material belt and U-shaped material belt extruded from the mouth die of the extruder in the melting state are evenly wound on the heated roller die according to the predetermined position, which ensures the quality of the fusion joint of the structure wall tube. In particular, in the structural design, the melt joint of the flat material belt is covered by a polyethylene-coated supporting tube, which improves the overall resistance to the external pressure of the product.
2. Good connection quality.
The pipe connection with excellent installation performance adopts the
embedded electric fuse in the socket with the same material socket welding
connection technology. It can achieve zero leakage, ensuring the same life span of the pipeline system and the safety of operation. At the same time, because the product under the condition of the same application as other tubes light weight, and is easy to transport, construction is convenient and quick, and can reduce the construction cost, in the range of applications, without a concrete cushion layer and concrete jaasiel groove can directly apply the tube after qualified, basically, stay do under excavation, side tube, while backfilling, simplifies the construction procedures, shortening the time limit for a project. During the project acceptance, the closed-air test is used instead of the closed-water test, which not only speeds up the acceptance but also saves the complicated work and a lot of test costs in the closed-water test
3. Good flexibility
High-density polyethylene winding structural wall pipe has macro flexibility, and the micro pipe section has strong rigidity and overall resistance to external pressure.
when used under heavy load road surfaces, it can ensure the safety of traffic. Due tothe flexibility of the pipe, it can also reduce the damage loss of the pipe to the minimum in the event of an earthquake, uneven surface settlement, and other geological activities. These characteristics improve the seismic mitigation ability of public facilities.
4. HDPE can be recycled, The main raw material of winding structure wall pipe
is green environmental protection products, such as high-density polypropylene, which doesn`t have any toxicity. There is no dye in the production process. The used pipeline can be 100% recycled. It is a green product of environmental protection.
5. Corrosion resistance, aging resistance, and service life span can be up to 50
years.
High-density polyethylene has the ability to resist chemical corrosion and
erosion. Therefore, when the winding structure wall pipe is conveying corrosive fluid or laying in corrosive soil, it does not need anti-corrosion treatment, and its performance is much better than other pipes. The product in the design process, chooses a reasonable product structure form, to ensure the service life span of the plastic pipe is more than 50 years, and no maintenance is needed in the life span.
6. Tube inner wall roughness, large water transfer around the structure of the
wall tube. Product inner wall roughness N is about 0.010, so the transmission of fluid has lower friction, compared to other products such as cement pipe with a similar diameter the water transfer is greatly improved. Therefore, the smaller HDPE tube can replace the larger cement pipes. In application, under the same conditions, using a wall pipe winding structure can have better reliability compared to the traditional pipe material. The comprehensive benefit is obvious, especially in the narrow construction site, high building density, underground pipeline, complicated traffic busy roads, and acid soil.
