Galvanized steel pipe is a kind of Carbon Steel Pipe, mostly welded pipe, Galvanized steel pipes are divided into cold galvanized steel pipes (electro galvanized steel pipes) and hot-dip galvanized steel pipes. At present, hot-dip galvanized steel pipes are mainly used in fire protection, electric power and highways.
Galvanizing can increase the corrosion resistance of steel pipes and prolong their service life. Galvanized pipes are widely used. In addition to being used as pipeline pipes for water transmission, gas, oil and other general low-pressure fluids, they are also used as oil well pipes and oil transmission pipes in the petroleum industry, especially in offshore oil fields, as well as pipes for oil heaters, condensing coolers, coal distillation oil washing exchanges of chemical coking equipment, as well as trestle pipe piles, support frames of mine tunnels, etc.
Hot-dip galvanizing (HDG), as referenced is the process of dipping fabricated steel into a kettle or vat of molten zinc.
Hot-dip galvanizing (HDG) is the process of coating iron, steel or ferrous materials with a layer of zinc. This done by passing the metal through molten zinc at a temperature of 860°F (460°C) to form zinc carbonate (ZNC03). Zinc carbonate is a strong material that protects steel and can prevent corrosion in many circumstances. Hot-dip galvanizing can be carried out cheaply and in large batches.

In the past few years, the topics of dumping and transportation that have been repeatedly discussed have become the focus of the industry once again with the official announcement of the first batch of recommended models for road dumping and transportation in the Ministry of Transport. Some people in the industry believe that the shipment of suspension and transportation in 2012 is expected to enter a substantive stage of development. 
Hang-and-hung transport, that is to use the front (trailer) trailer trailer to the destination, after the trailer off the trailer, replaced by a new trailer transported to another destination of transport, it set the car train transportation and loading and unloading hanging in one It is a centralized reflection of the organization, scale, networking, informationization, and standardization of the road freight industry. It has matured in developed countries and regions such as Europe and the United States.
According to relevant statistics, after the implementation of drop-and-hook transportation, companies can reduce the purchase cost or rental cost of the front vehicle by more than 50%, increase the average vehicle transportation productivity by 30% to 50%, reduce the cost by 30% to 40%, and reduce fuel consumption by 20% to 30%. . However, this kind of intensive and efficient transport organization model has been developing very slowly in China.
According to an expert who was involved in the development of related standards for dumping and transporting, in 2009, China had a total of 9.07 million trucks in operation, but only 290,000 tractors and only 330,000 trailers, accounting for only 3.2% and 3.6% respectively. . The ratio of the number of tractors and trailers is only 1:1.14. The number of tractors and trailers is small, and the ratio of trailers to trailers is low. Compared with the level of development of suspension of transport by developed countries, there is a significant gap.
At the beginning of January this year, the "Circular on Further Promoting the Healthy and Stable Development of the Road Transportation Industry" issued by the General Office of the State Council proposed that special funds be included in the funds for the purchase of vehicles to support the development of suspension of transportation. According to informed sources, the investment direction of related funds is mainly for large-scale projects and demonstration projects of pilot enterprises and the Ministry of Transport.
According to the "Recommended Types of Road Dropping and Transport Vehicles (First Batch)" formally announced by the Ministry of Transport on January 18th, a total of 16 vehicle models from 11 vehicle manufacturers were selected. Among them, FAW Jiefang, Dongfeng Commercial Vehicles, China National Heavy Duty Truck and Futian Auman have two types of tractors, SAIC Iveco Hongyan and each Beifang Heavy Duty Truck 1 tractors, and others are all dedicated vehicles.
Although people in the industry believe that with the promotion of policies, the development of drop-and-hook transportation is expected to enter the right path, and related beneficiary companies have already “hurryâ€, but in an interview with reporters for a number of heavy truck companies and distributors, most of them are interested in this new policy. The response was dull. Many companies believe that only the recommended models do not implement policy support, and the suspension of the transport trials has little practical effect.
“Without changing the logistics structure, it will be impossible to develop suspension and transportation.†A person in charge of the Brand Department of a heavy truck company believes that the current concentration of the domestic logistics industry is very low, and the industry management is also chaotic. The suspension and transportation needs to be scaled to do it. . The integration process of the domestic logistics industry needs at least five years or more, and it will not have any material impact on the heavy truck companies in the short term.

However, Tan Xiuqing believes that dumping and transport is a general trend. In the future, the promotion of drop-and-hook transport will greatly promote the improvement of road transport efficiency and the optimization of the structure of operating vehicles, and the gradual decline in heavy truck sales is inevitable.
"China's current logistics and transportation efficiency is very low. If logistics efficiency can be greatly improved, the phenomena of empty driving and 'cars and other goods' are reduced, then the current volume of goods does not require 1 million heavy trucks at all. With the promotion of dumping and transport A car can complete the current number of vehicles, which will greatly increase the efficiency of the use of vehicles.From the perspective of Japan and the United States, the peak sales volume of heavy-duty trucks is generally two or three years ahead of the peak of economic growth. On the way to Europe, what people see is basically tractor-trailer, because it has the highest efficiency of transportation. Although the situation of China's heavy-duty truck market is not the same as in Europe, the general direction of development is the same,†said Tan Xiuqing.
General comments:
In recent years, China is facing tremendous opportunities for regional economic growth and regional wealth transfer. With high-value-added, high-tech products and native products that have comparative advantages, the volume of trade has grown rapidly, such as general merchandise and household appliances. Road dumping and transportation, supply is stable and sufficient. In particular, with the implementation of development strategies such as “Rejuvenation of Northeast China, Rise of Central China, and Development of the Westâ€, the pulling force of the macro-environment on social demand continues to grow. West-East Gas Transmission, West-East Electricity Transmission, South-to-North Water Diversion and other projects, and 2010 The construction of a large number of national key projects such as the former World Expo project will stimulate the market demand for road suspension and transportation, and the transportation industry is ushering in a new round of golden season. The momentum for the growth of road suspension and transport performance is extremely abundant.
