FAQ:

Q1: Why buy Materials & Equipment from OKorder.com?

A1: All products offered byOKorder.com are carefully selected from China's most reliable manufacturing enterprises. Through its ISO certifications, OKorder.com adheres to the highest standards and a commitment to supply chain safety and customer satisfaction.

Q2: How many tons of steel products could be loaded in containers?

A2: Usually the steel products are delivered by bulk vessel because of the large quantity and the freight. However, there are no bulk vessel enter some seaports so that we have to deliver the cargo by containers. The 6m steel product can be loaded in 20FT container, but the quantity is changed according to the size, usually from 18tons to 25tons.

Q3: How soon can we receive the product after purchase?

A3: Within three days of placing an order, we will arrange production. The normal sizes with the normal grade can be produced within one month. The specific shipping date is dependent upon international and government factors, the delivery to international main port about 45-60days.

Q:The previous track is seamed, there is no gap, is how to achieve
In order to solve the problem of thermal expansion and contraction of rail fundamentally, the research group of seamless rail technology has studied and invented a new type of temperature force transfer structure - shear bonding structure. This structure uses solid solvent-free thermal curing adhesives will switch long core rail and wing rail, interval iron cemented into one, the shear strength of the adhesive, seamless line temperature force of an interval through switch to another normal transmission interval. Like Taiji, the force of heat and cold contraction will be transferred to the track next to it without accumulating on the seamless rail.
Q:Why not Rail Rail corrosion?
As the train passes, the constant rail friction with the wheel rust away.
Q:Why is rail insulated?
Rail is the main component of railway track. Its function is to guide the wheel of the rolling stock, to bear the great pressure of the wheel and to deliver it to the sleeper.
Q:What's the gauge for the high speed rail?
The rails of China's high speed rail are usually 1435 millimeters.
Q:Seamless rail is not afraid of expansion and contraction?
Seamless rail is also afraid of thermal expansion, cold contraction, but better than ordinary steel pipe. Thermal expansion and contraction are the laws of physics. When heated, the distance between molecules increases, and the rails extend. Similarly, cold contracts.
Q:Generally, how often do rail rails change?
But the passenger dedicated line, such as the Beijing-Shanghai high-speed railway, the Wuhan Guangzhou high-speed railway, the Beijing Tianjin Intercity Rail replacement, the cycle is very long, generally can reach ten years or even in the past 20 years, because of the high iron light axle load, line status, and problems of the rail wear less, low probability.
Q:What is the connection mode of the return cable on the rail?
After the two connection, the tested cable is passed through the current transformer.
Q:What are the main functions of nondestructive inspection of rail defects?
Even endanger personal safety. Using nondestructive testing, RT, MT, PT and other conventional testing methods, it is easy to find defects that are difficult to observe by the naked eye. Prevent accidents and ensure quality.
Q:What kind of steel should be used for railway rails?
The rail locomotive need to withstand pressure, friction and shock loads, required strength, hardness and toughness sufficient, high quality requirements, we must test its mechanical properties and macrostructure and drop test etc.. "High strength, high toughness bainitic rail" and the major technological project undertaken by Baotou Steel Group, "rare earth high strength weathering steel", was identified by experts. Experts agree that bainitic rail is a major breakthrough in the history of rail material research and development, filling the gap of high-speed and heavy rail in China and reaching the international advanced level.
Q:55Q rail performance
Rail is the main component of railway track. Its function is to guide the wheel of the rolling stock, to bear the great pressure of the wheel and to deliver it to the sleeper. The rail must provide a continuous, smooth, and least resistant rolling surface for the wheel. In electrified railway or automatic block section, rail can also be used as track circuit.
