High Frequency Pipe Welding Machine is a equipment which belongs to cold roll forming, also belongs to high frequency hot welding forming. The high frequency is same with other roll-formed profiles machines, de-coiling, leveling, cold roll forming, while the High Frequency Welding Machine is welded by high frequency after it is formed by the stations of rollers. high frequency pipe welding machine can produce different shapes of tubes or pipe by changing the mold, in a word, one high frequency pipe welding machine can produce the square tube, the round tube, the rectangular tube.

LED is one of the major breakthroughs in human light source technology after Edison invented the electric light. In the article on the wrestling between LED and energy and the environment, I mentioned the conflict between LED technology and environment and energy. Indeed, We can't stop the evolution of lighting source technology, and it is difficult to reject the soft and hard of science and technology to bring convenience to life. Perhaps it is too much worrying about the hot brother. When I think that the global population has already exceeded 7.5 billion, the population that has grown in the past five years is the total population of nearly two US countries. In addition to the recent excessive climate anomaly in the earth, I feel that the future of mankind will be In the face of increasingly stringent climate anomalies, environmental pollution, global warming, energy exhaustion and other issues, I feel whined. Today, let's put aside the environmental issue for the time being, to talk about a new trend of night economy in the LED industry. China's service industry has become the key to economic restructuring. China's GDP growth rate in 2016 was 6.7%, a 26-year low, and economic growth began to slow down. The focus of China's economic restructuring is to transform from a world factory to a world market. China has 1.3 billion. The population's domestic demand market is sufficient to support China's transformation from manufacturing to emerging service industries. The Chinese government plans to increase the proportion of tertiary industry to 56% in the next five years. The service industry has become the main driving force for China's future GDP growth. The relevant policies of the 13th Five-Year Plan have been issued one after another. The most important focus is the Internet + the healthy China and the beautiful China that have extended the transformation of the emerging service industry. Beautiful China's big strategy will detonate domestic tourism demand In 2015, China's domestic tourists exceeded 4 billion passengers, and domestic tourism revenue reached 3.43 trillion yuan. With the increase in disposable income and meeting basic living needs, consumers began to experience spiritual consumption. As a result of the rapid development of culture and tourism, the Twelfth National People's Congress issued the 13th Five-Year Plan. The Outline mentioned many times the combination of culture and technology, and it is also a policy trend. A city's famous natural scenery at night, through the local government to implement the landscape lighting / lighting project, can continue the beautiful scenery, enhance the local night travel economy, the time axis covers all kinds of consumption from 7:00 to the next morning. Such as: ticket income, catering, shopping, accommodation and other related consumption, the efficient income brought by the night economy has become a new impetus for the development of modern urban economy.
