On April 1st, the e-commerce platform “Car Girl”, which has been awarded millions of angel financing, was officially put into operation, focusing on car door-to-door maintenance services. The data shows that the size of China's automotive aftermarket in 2014 has reached 690 billion yuan, a year-on-year increase of 30%, and is expected to rise to 900 billion yuan in 2015. The “cake” in the aftermarket is very attractive. The auto service market will still focus on vehicle maintenance and maintenance. Especially with the continuous increase of car ownership in China and the rapid development of mobile internet, car door-to-door service has gradually become a service. The market for automotive aftermarket is more concentrated. Compared with the store service, what are the advantages and disadvantages of on-site service? What about the future development trend?
Recently, after the reporter personally experienced the car washing and maintenance services provided by several car door-to-door service providers, I felt that the on-site service has obvious advantages over the traditional service. With the continuous expansion of the market in China after the maintenance and repair of automobiles, the use of on-site services is becoming more and more extensive. The repair, maintenance, decoration and even electric vehicle charging of automobiles can be completed through on-site service. However, it is still necessary to upgrade and upgrade the on-site service to become the mainstream automobile maintenance model.
â–  Wide market capacity The market capacity of vehicle maintenance, maintenance, car washing, decorative beauty and car ownership is positively related to the average car age of the vehicle, that is, the greater the car ownership and the average age of the car in use, the greater the market capacity.
According to data released by the Ministry of Transport and the Ministry of Industry and Information Technology, in 2014, the number of passenger vehicles in China has reached 160 million. Among them, mid-to-high-end passenger cars accounted for 32%, about 43.84 million; high-end passenger cars sold more than 2 million in 2013. There are 31 cities in the country with more than 1 million passenger cars. The number of passenger cars in Beijing, Tianjin, Chengdu, Shenzhen, Shanghai, Guangzhou, Suzhou and Hangzhou has exceeded 2 million.
Wang Wei, deputy general manager of Yantian City, Yancheng City, Jiangsu Province, said that the number of cars in the United States reached 280 million, with an average age of more than 10 years. China's car ownership reached 160 million at the end of 2014, but the average age of the car is only about 4 years. Therefore, compared with mature markets such as the United States, the market size is relatively small. However, as China is the world's largest new car sales market, it is the world's number one car growth rate. It is estimated that within 10 years, China's car ownership will exceed 350 million, ranking first in the world, and the average age will gradually increase. To 6~8 years. By then, China's automobile repair and maintenance market will become the world's number one.
Wang Baoxue, chairman of Beijing Huanyue Technology Co., Ltd. believes that the proportion of motor vehicles has changed fundamentally. Passenger cars have become the mainstay of motor vehicles, and private cars have grown by spurt. The Chinese automobile society has quickly entered the era of car transportation. The huge passenger car ownership has created a huge demand for the passenger car maintenance market, but China's traditional passenger car maintenance service industry is difficult to meet the growing demand. This situation prepares a natural market for the development of the on-site service industry, and will become larger and larger. "Car door-to-door service can not only fill the gap in market demand, but also help the auto repair service industry to upgrade and upgrade." Wang Baoxue said.
â–  Unique advantages For users, the biggest advantage of on-site service relative to store service is convenience, saving time, effort and worry. The store service requires the user to drive the car to the designated location within the scheduled time, which undoubtedly takes up a whole period of valuable time for the owner. If the traffic jam occurs on the way, the time taken is longer. On the contrary, if it is on-site service, the owner can use the scattered time of work and life to take care of the car. For successful people whose time is money, or for lazy people such as otaku and housewives, on-site service is indeed a welfare.
As for saving money, it has not yet been seen that it is the main advantage of on-site service. After experiencing the services provided by several on-site service providers, the reporter found that some on-site service prices are lower than the store service, while others are similar to the store service price, and some are more expensive than the store service. For example, the price of the easy-to-repair car wash experienced by the reporter is 99 yuan, which is much higher than the average price of about 15 yuan for the car wash. Therefore, it is still not possible to say that the on-site service must be better than the store service offer. Of course, saving money is true, but this does not seem to be the primary concern of car owners. Easy-to-repair service staff summarized the advantages of several on-site services relative to store services: because there is no need to go to 4S store maintenance, each car can save 160 liters of fuel per year; it can reduce exhaust emissions and benefit the environment; to a certain extent The vehicle traffic accident rate has been reduced; the traffic congestion in the city has been slowed down due to the reduction of vehicles on the road.
A service manager of the car geek believes that the car door-to-door service is a revolution and industrial upgrade for the passenger car maintenance service industry in China. On-site service is generally based on mobile internet technology, with mobile maintenance service platform, generally service vehicle as service carrier, providing customers with active, standardized, transparent and precise passenger car small repair and maintenance services.
Wang Baoxue said that after the car door-to-door service became the mainstream maintenance service model for automobiles, it could also save a lot of land occupied by the construction of traditional 4S shops and maintenance shops. “If the mobile service platform is built as a pure electric service vehicle, then the platform will not have any emissions. If the on-site service is transformed into a closed operation, it will ensure that the 'three wastes' will not be lost during the maintenance process, and maintenance will be eliminated. The pollution of land and groundwater resources ensures that all waste parts and waste oil are recycled and scientifically processed," said Wang Baoxue. According to the Document No. 186 issued by the State Ten ministries and commissions (No. 186, “Guiding Opinions on Promoting the Transformation and Upgrading of the Passenger Car Maintenance Industry and Improving the Quality of Service”, the current domestic automobile maintenance industry has insufficient market structure and development. Regulations, backward service models, opaque consumption, and insufficient service integrity are directly related to road traffic safety, related to air pollution prevention, mass quality of life, and the healthy and sustainable development of the automobile industry. The door-to-door service utilizes mobile internet to implement the “one-stop” mobile maintenance service model, which is the expansion and extension of the operation mode. It is the transformation, upgrade and innovation of the service form, optimizes the service process, makes the service information transparent and transparent, and expands the service. The scope and capabilities have improved the quality of service and achieved green maintenance operations that will benefit the society and car owners.
Because of these advantages, car door-to-door service may become the mainstream service form of car maintenance and repair services in the near future.
■ Larger room for improvement Compared to store services, the disadvantage of on-site service is the need for improvement. At present, the biggest disadvantage of on-site service is that it is limited by the venue, technical tools and other restrictions, and the service items are not as good as the store services. For example, sheet metal, four-wheel positioning, painting, replacement of side panels and other major repairs, on-site service can not be completed or not completed well. A senior practitioner in the auto repair industry said that although the painting can also be completed through on-site service, the quality of the painting cannot be effectively guaranteed because the environment cannot be kept clean. In other words, certain car maintenance projects must be completed at the store, so the “convenience” provided by the on-site service to the user is still limited.
In addition, the status quo of hardware such as on-site service vehicles and service tools is not very optimistic. On the one hand, service vehicles are generally small, and light passengers and even MPVs are often used. Apart from the member space, only one trunk can be loaded with tools, which severely limits the service capacity. The special service vehicles modified for on-site service are far from universal; On the one hand, the service tools have not yet been professionalized, and some tools are still relatively simple.
There is also room for improvement in the on-site service process. For example, there are two problems mentioned in the door-to-door car wash: one is that the service car enters the mid- to high-end property due to the cross-flow of sewage; the second is because the door-to-door car wash is a micro-washing car, and some mid-to-high-end car owners are worried about scratching the surface of the car body. Such services will not be considered. In this regard, industry experts believe that the first problem can be partially solved by placing an absorbent pad under the car. For the second problem, it is also necessary to solve the problem by optimizing the car wash solution.

API 6A Flange

The difference between ASME/ANSI and API is the fabrication material and a higher rated API operating pressure.

ASME/ANSI flanges are commonly used in industrial process systems handling water, steam, air and gas. API flanges are manufactured for high strength operating refinery systems with products such as oil and explosive gases.

The flange standards API 6A and ASME/ANSI B16.5 have the same dimensions – but the API 6A flanges are rated for higher pressures as indicated below:
