China Railway Qingdao World Expo City – Metal hose

Metal hose Contract of China Railway Qingdao World Expo City

Shanghai Songjiang Shock absorber Group Co., Ltd. official website for you to introduce: [China Railway Qingdao World Expo City] metal hose contract information, Songjiang Group for many projects supporting metal hose, the following is for China Railway Qingdao World Expo City supporting metal hose in detail.

I. Introduction to China Railway Qingdao World Expo City

Qingdao World Expo City project is one of the leading projects being promoted by Qingdao Ocean High-tech Zone. Since the contract was signed in October 2015, the contract was signed in the same year and the construction started in the same year, making rapid progress. After more than 1years, to what extent is the current construction?

Recently, the reporter walked into the construction site of China Railway Qingdao World Expo City to visit the progress. In such a huge construction site, the construction area of “Maritime Silk Road” International Conference Center complex comes into sight first. A rectangular foundation, more than 600 meters long and 120 meters wide, has been dug and workers are working on the site. According to the design, the building form of the Convention Center complex is like an unrolled ribbon, and the streamlined elements of waves are introduced in the facade, implying the development strategy of “lead the road”, and fully reflecting the Marine culture and new vitality of the West Coast.

Not far north of the convention center, six steel and concrete core columns stand in the construction area of expo City’s exhibition halls. The pavilion project is designed with an “array” structure, with a “cross” corridor separating the 12 standard pavilions symmetrically from east, west, north and south. The design of the pavilion incorporates elements of the local historical site “Langya Terrace”, and divides the exhibition hall into four groups, which correspond to the four seasons, 12 months and 24 solar terms of the traditional Chinese calendar.

Is the site of command construction of China Railway Tianfeng Construction Engineering Co., LTD. * chief engineer told reporters, and ordinary buildings compared to the exhibition hall here gallery construction is more difficult. “We have 12 standard galleries, each with a cross axis gallery as the core. All of them are tubular trusses. Each truss, 135 meters long and 72 meters wide, is light in design but complex in structure. It weighs 1,000 tons, has more than 4,000 nodes and took three months to put together. We need a hydraulic lift to lift the whole frame and straighten it into place.”

According to reports, China Railway Real Estate Group seized the approval of Qingdao West Coast New Area.* New area of the major opportunity, investment 50 billion yuan, in the west coast new Area of the core area planning and construction of 3000 mu of China Railway Qingdao World Expo City. After the completion of the Project, China Railway Qingdao Expo City will become an exhibition center with large exhibition area, complete functions, complete supporting facilities and high technology level in Northeast Asia, and become a bright name card of Qingdao West Coast New Area.

Ii. Introduction of metal Hose Contract for China Railway Qingdao World Expo City

The following is the scanned copy of the authentic contract, please do not reprint or modify. This contract is only used as the certificate of the first shipment, not for other purposes. Thank you for your cooperation.

Iii. Introduction of metal Hose used in China Railway Qingdao World Expo City:

The contract mainly includes: outdoor directly buried corrugated compensator, stainless steel metal hose, corrugated compensator, stainless steel bellows several products.

1. Introduction of outdoor directly buried corrugated compensator:

Directly buried corrugated compensator is suitable for only axial displacement in the pipeline, the product has the ability to compensate lateral displacement and axial and lateral combined displacement, but because the compensation amount is small * only as axial compensation can play its better. Longer service life, safer and more reliable.

Directly buried corrugated compensator (also known as directly buried compensator) is mainly used for axial compensation of directly buried pipeline, with bending resistance, so the impact of pipeline sinking can not be considered, the product has a large amount of compensation, long life. Points. Axial compensation: 30mm-500mm

Buried corrugated compensator by * or more bellows in series connected in *, the bellows have the outer sleeve that can make the bellows move axially, that is, the protection device, and maintain its stability.

2, stainless steel metal hose introduction:

The hose bellows are made from. Thin-walled seamless or multi-welded stainless steel tubes formed by high precision plastic processing. Due to the elasticity of the bellows profile. The flexible hose has good flexibility and fatigue resistance, so that it is easy to absorb the cyclic load of various movement deformation, especially in the pipeline system has the ability to compensate large displacement. I plant in addition to the original production of hose excellent equipment, 1998 also introduced two high-precision, high-tech bellows automatic welding forming production line, greatly improved the quality of hose and make the hose length is not limited, to meet the needs of ultra-long hose.

The net sleeve is the main bearing part of the hose installed in the pressure pipe, and plays a protective role on the bellows, according to the pressure in the pipe size and the application place, can choose * layer or multilayer stainless steel wire or steel belt for braided.

As the main parts of the production of hose material is to adopt austenitic stainless steel, thus ensuring the hose excellent temperature resistance and corrosion resistance, hose working temperature range. Large, -196-600oC, the use of the hose according to the corrosive medium of the pipeline to choose the use of stainless steel *, can ensure the hose corrosion resistance.

Corrugated metal hose has good softness, fatigue resistance, high temperature resistance, high and low temperature resistance, corrosion resistance and so on. Sex, his relative other hose (rubber, plastic hose) life is much higher, so it has higher comprehensive economic benefits, with the development of modern industry, the demand for high temperature resistance, high pressure resistance of corrugated metal hose is also increasing.

Scope of use of hose: fully flexible conveying pipe, prevent vibration of the space pipe, steam, gas, air, heavy oil, petroleum, chemical drugs are used.
