With the rapid development of economy, the trend of urbanization is becoming more and more obvious. Some experts pointed out that urbanization is a double-edged sword, which is extremely unfavorable to China's economic development. However, in the development of elbow pipe fitting industry, urbanization does promote the rapid and stable development of pipe fitting industry. According to the report of the reporter, the application of high pressure elbow pipe fitting in many industries shows a significant role and makes a significant contribution to the development of pipe fitting.

The gradual development of urbanization has brought unprecedented opportunities to the elbow pipe fitting industry. At the same time, it is also crucial for the development of pipe fittings. At present, shengtian pipe fittings in the process of accelerating the grass-roots construction, the demand for elbow pipe fittings products is also increasing. Pipe fittings is a professional production of various pipe fittings manufacturers, the products are sold around the world, a large number of users are generally welcomed. In the past, traditional steel pipes and elbows were generally selected for drainage, heating and gas supply in cities and towns, and manufacturing techniques could not fully meet the development needs of the industry. In the future urbanization development and construction, all kinds of elbow pipe fittings will be greatly increased. As we all know, traditional pipe connections have many defects, including poor material, corrosion resistance and impact resistance. Not only that, the old city facilities also exist in the aging and other security risks. It is believed that the new urbanization construction will certainly bring new opportunities to the development of high pressure elbow industry.

Now stainless steel elbow rust, you can use special cleaning agent to clean away the rust. And in peacetime use of time should also pay more attention to its cleaning. For example, when the surface of the elbow has dust or stains that are easy to remove, it can be washed with warm water or weak detergent, or with soapy water. And when its surface has trademark or sticky stick film when, also can use weak scour cathartic, want to remember to rinse with clean water finally and dry cotton cloth wipe.

When installing, the stainless steel elbow can be directly installed on the pipe in accordance with the connection mode and the position used. In general, can be installed in any position of the pipeline, but need to facilitate the inspection of the operation, pay attention to the cut-off stainless steel elbow medium flow direction should be longitudinal disc downstream, stainless steel elbow can only be installed horizontally. Stainless steel elbow in the installation should pay attention to the sealing, prevent leakage phenomenon, affect the normal operation of the pipeline.

Stainless steel elbows do not cause corrosion, pitting, corrosion or wear. Stainless steel is also one of the strongest metals used in construction. Because stainless steel has good corrosion resistance, it can make structural components to maintain the integrity of the engineering design permanently. Chrome-containing stainless steel is also a combination of mechanical strength and high ductility, easy parts processing and manufacturing, can meet the needs of architects and structural designers. All metals react with oxygen in the atmosphere to form an oxide film on the surface. Unfortunately, the iron oxide formed on ordinary carbon steel continues to oxidize, causing corrosion to expand and eventually forming holes. Paint or oxidising resistant metals such as zinc, nickel and chromium can be used to coat carbon steel, but, as is known, this protection is only a thin film.

Corrosion resistance of stainless steel depends on the alloying elements contained in the steel. Chromium is the basic element to make stainless steel corrosion resistance, when the amount of chromium in steel reaches about 1.2%, chromium and oxygen in the corrosive medium, in the steel surface into a very thin oxide film (self-passivation film), can prevent further corrosion of the steel matrix. In addition to chromium, commonly used alloying elements also include nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the requirements of various USES of stainless steel structure and performance.

Stainless steel elbow stainless steel raw materials are chromium, nickel and other elements in gamma-fe formed in the gap of solid solution, is a major type of stainless steel. Its main characteristics are: non-magnetic austenitic arrangement at room temperature, low flexural strength ratio, good plasticity, excellent welding function, easy to exercise and cast forging hot forming; It is rich in chromium (more than 17%), nickel (8%-15%) and other progressive corrosion resistance elements (such as molybdenum, niobium, titanium, etc.). Therefore, austenitic stainless steel not only
Urbanization promotes the rapid development of high pressure elbow industry

Per capita living standard progress is not the desire to buy a car and buy a house, in the past few years housing prices have gone up in the past few years, which also accounted for a large number of reasons. In the real estate price rise also let the real estate company for it crazy, in the real estate company crazy building frenzy also followed. Buy a building to build a building in that time of zhang crazy how zhang crazy, each major profession inserted a hand in ground industry. But from a year ago to buy a house heat also began to cool, and a real estate company is also a heavy loss. The heavy drugs have finally been reversed. The progress in per capita income does not mean that all the people are able to purchase. When buying a building hot drop in temperature, also be the normal expression of average income. And pipe fittings industry also is hit badly, also have a bit depressed from now on. The plumbing industry has been hit by the slump in the local industry, but another industry that is booming is the car industry. Now the countryside has been developed in an outstanding way. In recent years, although the buildings of 200,000 or 300,000 on the small side of millions are often daunting, there is still a certain talent for purchasing 20,000 to 100,000 vehicles. The car industry, which saw a drop in home-buying, rose steadily. Welded steel tubes for cars are one of the most important types of precision welded tubes. In such a fierce competition in today's professional mobile pipe fitting promotion points is the king. In addition, stainless steel pipe in the car is also a lot of application. Stainless steel pipe is mainly used in the exhaust system of cars, accounting for more than 1/2 of the total amount of stainless steel of cars, 80% of ferritic stainless steel. Exhaust gas from the engine of a car flows out of the muffler at last through the exhaust gas inlet pipe, front pipe, hose, converter and center pipe. Exhaust system commonly used steel 409L, 436L and so on. Car muffler first use stainless steel welded pipe. It is estimated that the use of stainless steel tubes in cars accounts for about 1.5% of the total consumption of stainless steel tubes by downstream users, while the use of stainless steel seamless tubes and welded tubes accounts for about 2:1. Many pipe fitting occupation in the car occupation to find its own business opportunities pipe fitting occupation of other enterprises are still waiting for what?

The lack of professionalism in pipe fitting has also made it difficult to sell iron ore, which has been deposited in the port of Qingdao by tens of millions of tons. Steel mills in the market needs to be full of the situation has not been the practice of steel, but the appearance of this, it can be seen that China's economy has been in trouble. In the old days, this meant a lot of money, but now nobody wants to stay in port. The ore is usually ordered by traders or steel mills, but with lower iron ore prices and less demand, many mills won't meet contracts and traders can't find a replacement, leaving the ore piling up in ports. Qingdao port is one of China's largest iron ore import ports, iron ore imports accounted for almost one seventh of China's total imports. There used to be more than 10,000 trucks and more than 30 trains full of iron ore every day, from the port to hebei, shanxi, shaanxi and other inland provinces of China -- trucks are two stories high, each train is 1.5 kilometers long, the huge traffic flow seems to be a river. But in the past six months, the river has begun to break. China's steel demand growth slowed to 8 percent in 2011 and perhaps 4 percent in 2012 as the world's largest producer, according to the China iron and steel association. The drop in steel output has directly affected demand for iron ore and coking coal, the two main steelmaking commodities.

It is understood that the iron ore in Qingdao port is in a difficult situation, now steel mills can only maintain a minimum amount of work, traders all walk on the dock, all the iron ore in Qingdao port has nearly 15 million tons, in order to pile up iron ore even office buildings have to be removed. A pipe fitting is a part that connects a pipe to a pipe. According to the connection method, it can be divided into socket pipe fitting, threaded pipe fitting, flange pipe fitting and welded pipe fitting. It is often made of the same material as the pipe. There are elbow (elbow pipe), flange, three-way pipe, four-way pipe (crosshead) and reducer pipe (size head), etc. A bend where a pipe turns; a bend. A part of a flange used to connect a pipe to a pipe, connected to a pipe end, and a tee pipe used to a place where three pipes meet; A four-way pipe is used for the gathering place of four pipes; Reducer is used for connecting two pipes of different diameters. China is already the world's largest producer and consumer of building materials. The output of major building materials such as cement, flat glass, buildi

It is the article that connects two parts of conduit or other conduit fittings, include 3, 4, elbow, elbow, sealing head, flange to etc. Industrial metal pipe fittings have the characteristics of strong specificity, high added value and wide application, involving various fields of national economy. The products are mainly supplied to petrochemical, natural gas, shipping, electric power, medicine and other industries, especially the emerging fields of Marine engineering and nuclear power.

The rapid development of the downstream industry of industrial elbow pipe fittings will drive the strong demand of large diameter, composite materials, high performance and high reliability pipe fittings. At present, the total demand for industrial metal pipe fittings in the power industry has declined, mainly due to the declining demand for installed pipe fittings for thermal power with low technical content and general performance. However, wind power flanges, nuclear grade pipe fittings and large diameter, non-standard, high-performance pipe fittings and other key components of thermal power units are still in short supply, some of which need to rely on imports. With the acceleration of China's urbanization infrastructure construction, the development of oil and gas fields, the transfer of world ship orders, the exploration of Marine resources, the construction of nuclear power stations and other projects will make the market that has been in short supply have a larger gap between supply and demand.

According to the analysis, in the next few years, the annual consumption of middle and low pressure industrial metal pipe fittings in China will be about 1.5 million tons, and the annual consumption of high pressure industrial metal pipe fittings will be about 2.3 million tons. Combined with the export business, the annual demand of China's industrial metal pipe fittings industry will be about 4.5 million tons. The annual industrial consumption of medium and high pressure pipe fittings in the world is at least 23.4 million tons and the market capacity is more than 90 billion us dollars.

Stainless steel pipe fitting operation needs to have a certain slope, the water supply stainless steel pipe fitting in the lowest point to install drainage plug or drain valve, stainless steel pipe fitting slope should slope to the drainage device, in order to facilitate the smooth flow of stainless steel pipe fitting and maintenance of the empty. The slope of stainless steel pipe fittings shall meet the following requirements:

(D) the slope of water supply stainless steel pipe fitting installation should be consistent with the direction of medium flow of stainless steel pipe fitting, the slope should be consistent and the slope should be straight. The horizontal water supply pipe shall have a slope of 0.002 ~ 0.005, and generally it shall have a standard slope of 0.003 and a slope drainage device.

(slope of force automatic spraying and water curtain fire fighting stainless steel pipe fittings, slope of water filling system should not be less than 0.002; The slope of the pneumatic system and branch pipe should not be less than 0.004 stainless steel pipe fitting after installation, slope, slope direction and stainless steel pipe fitting bracket elevation, level should be carefully checked, check, to ensure that the slope of stainless steel pipe fitting and the actual situation, design requirements.
