At present, the pipeline has become the transporting measure with the largest transmission capacity superior to railage, road transport, waterage and air transport in the world.

　　 Pipe fittings are the coupling parts of various pipelines. Nowadays,the yearly requirement for pipe fittings in international markets of low pressure and medium & high pressure is up to 90,000,000,000$. Because of the environmental protection and the cost of production etc, developmed countries have stopped the production of pipe fittings. As the uppermost provider in the world, China occupies a huge a market. However, we still follow the traditional coupling measures such as thread, electric welding and flange invented 200 years ago in pipeline installation projects. They have a lot of shortcomings, especially the running, emitting, droping and leaking, which bring about a great economic loss in the society. Although there are groove type pipeline coupling technology and pipe fittings imported from America in the market now, as they demand high installation technology and complex construction technique, the price is rather high and they can't assure the pipelines from seeping and leaking.

　　 Pro.Ge Wenyu, the president of Dalian Yongan Pipe Fittings Co.,Ltd. invented the brand new Movable-Joint Flexible Socket Joint Coupling (Mr.Ge Coupling for short) as the fourth coupling measure and. Four structures and ten series of pipe fittings are developed according to this technology, which install easily, save time, shorten the time limit and reduce the cost of a project. The biggest characteristic of this technology is to avoid leaking for at least 50 years. It has declared 27 patents in China and international patents that can cover more than 120 countries and regions in the world by PCT.

　　 Yongan Pipe Fittings have a wide application under various working pressure and temperature, which can be used together with steel pipes, cast iron pipes, stainless steel pipes, copper pipes, plastic pipes, compound plastic pipes and other pipelines made of different materials.

　　 As the upgrade product of traditional ones, Yongan Pipe Fittings will clean out the traditional coupling measures which have shortcomings of seeping and leaking step by step. The technology is the pioneer in the world, which is monopolistic and has pretty high technology bulwark, and the market risk is rather low. Now, the key management team of Yongan Company has completely formed, movable-joint pipe fittings have finished the experimental production phase, the technologies of pipe fittings, production technique and equipments have met the requirement of large-scale industrial production.

　　 Presently Yongan Company plans to make a financing of RMB 573,000,000Yuan (about 70,000,000$) to build a standard factory whose yearly output of pipe fittings is 120,000t, as well as a processing factory for special purpose transfer machines and a supplying base for raw materials. It is conservatively expected that the rate of return on investment after their putting into production is up to 135%, and the payback period(including construction period) is 1.84 years.

　　 It is a good deal to invest in Yongan Pipe Fittings, which benefits the nation, the people and the investors. It can not only arrange a large amount of social employment, but also create a great amount of favourable tax revenue. The market is so large that the amount of low-pressure and medium & high-pressure pipe fittings needed in the world each year is totally 35,000,000t. Regarding the factory with an annual capacity of 120,000t pipe fittings as the standard, we need to build more than 290 such standard factories to meet the demand of the world. This is a very mighty cause.

　　 We can see the general benefit to invest in building a standard factory with an annual capacity of 120,000t Yongan Pipe Fittings from the following table.

　　Pipelines, as the 5th invention in human modern history, are widely used and the invention of pipelines is very important for human society to march towards the civilization and advancement. They bring a lot of convenience and advantage to human life and production. The pipeline is the most economic, convenient, and safest transport carrier in the five major carrying trades of the world. Calculating according to the ton kilometer, the transport cost of the pipeline is 1/3 of the waterage, 1/6 of the railage, 1/18 of the highway transport and 1/500 of the air transport. So the pipeline has developed very fast and become the biggest transport carrier in the world now.

　　 The pipeline can not only send gas, liquid but also has been expanded to transport gruel, powder and granule objects such as dirt and coal. Maybe one day when pipeline trains come true, pipelines can also be engaged in transportation of passengers, more materials and even space transport. In a word, the pipeline really brings great convenience and advantage to human life and production.

　　 Under the concealing of enormous merit of the pipeline, people has neglected his shortcoming and insufficient: All pipelines exist running, emitting, droping, leaking.

　　 People have been used to the fact that each building and each factory can not be short of plumbers because pipes always leak and we need someone specializing in repairing the pipes.

　　 Over the past 200 years, with the birth of pipelines, people have invented three kinds of coupling measures: thread, electric welding and flange, which are the main curses causing the pipeline's running, emitting, droping and leaking. It has been investigated and verified for many times that 98% of the leak take place at the joint of the pipelines. In developed countries, the rate of leak is averagely 5-20%, the rate in developing countries is 10-30% and it is averagely 20% in China. It can not only cause enormous social resources to be wasted, but also the leak of flammable gas can cause explosion and fume people to death. The leak of poisonous gas and liquid can even bring about pollution of the environment. For example, flowers and grass don't grow around some chemical plants, even birds don't fly over there and the underground water is also polluted not to be drunk.
　　 The pipeline saves a large amount of transport costs for human society, but the leak causes great economic loss. The economic loss in China each year caused by leak of pipelines is up to more than RMB200,000,000,000Yuan. So we have to solve the problem of running, emiting, droping and leaking, which is ubiquitous in the whole society even in the whole world.

　　It's a pity for us living in the 21st century to still use the pipeline coupling method invented in 18th and 19th century.

　　 As the unique organization specializing in research of pipeline coupling technology in the world, Dalian Yongan Pipeline coupling Technology Institute is founded to solve the difficult problem. Yongan series of patented products developed in recent years can thoroughly solve the problem of running, emiting, droping and leaking. We have successively declared 27 patents on pipeline coupling technology to National Patent Department and 3 international patents that can cover more than 120 countries and regions in the world by PCT. The patent invention has obtained Einstein International Science & Technology Invention Award, National First Invention & Innovation Jinzhi Award and Gold Medal of London International Patented Technology Fair. The product has gained the certificate of ISO9001：2000 Quality Management System and has been listed in national standards and teaching materials in universities. In order to quicken up the spread of the application, the Ministry of Construction ranked Yongan Pipe Fitting as the national key spread item of scientific achievements in 2003.

　　 With Yongan Pipe Fittings series of patented products, we can not only realize the no-leakiness but also the safe running of pipelines. It is valued by Pro. Wu Yuanwei, the most authoritative expert on pipelines, Chief Engineer of China Construction & Science Academy, that Yong'an Pipe Fittings is an epoch-making revolution of pipe installation in world history in the 21st century. Yongan Pipe Fittings is a revolutionary invention & creation valued by Pro. Zhu Shiqing, academician of Chinese Science Academy and headmaster of China Science & Technology University.

　　 Pipelines of no-leakiness will be more perfect and creat more economic values for human society. The whole society should all extend the application of Yongan Pipe Fittings because it supplies the society environmental protection, energy-conservation, economical and safe assurance to us. It will benefit the whole human society.
