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 do we guarantee the quality of our products?

A2: We have established an advanced quality management system which conducts strict quality tests at every step, from raw materials to the final product. At the same time, we provide extensive follow-up service assurances as required.

Q3: How many tons of steel products could be loaded in containers?

A3: 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.

Q4: what is the difference between actual weight and theoretical weight?

A4: All the section steel has two weights: actual weight and theoretical weight. Actual weight is the weighing out when the product delivered from the mill. Theoretical weight is calculated by pieces.  The invoice can be based on each of them as your request.

Q:High iron seamless rail is how to solve the problem of the thermal contraction account?
There is a direct relationship between changes due to temperature stress in CWR under the size and temperature of rail, so we locked rail must be correct, reasonable selection of locked rail temperature, to ensure the CWR winter break, summer is not caused by track swelling, endanger traffic safety.Seamless rail to solve the heat up, cold contraction, light by a small number of cracks is not enough, and now solve the heat up, cold contraction, there are two ways. One is the long rail itself to bear all the temperature stress, the long rail is locked on the sleeper, so that it does not shrink due to temperature changes. This method applies to areas where the temperature varies slightly throughout the year, for example in southern china. In some temperature difference regions should take another approach, namely the long rail itself does not bear the temperature stress, and stress or regular bleeding stress to automatic bleeding, make the long rail with temperature rise and free shrinkage, at the time of laying also try to choose the best temperature of laying the rail expansion value in the minimum range, so that regardless of temperature rising or falling, the rail expansion always control in the smallest range.
Q:How are the rail tracks worn?
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.
Q:The difference between small resistance and constant resistance fastener of high speed rail
The second point adopts the tight pull, that is, the fastening of the rail is more firmly fixed on the ballast bed with the new fastener, and the high-speed railway basically adopts the ballastless track technology, and the fastening performance is better than that of the common railway.
Q:What is a rail pile?
Rail pile: through the large air compressor air supply to the impactor, the use of YG-80 engineering drilling machine drive special drilling hammer, impact hole. Then enter the rail, and then pour the cement mortar from bottom to top. After solidification, the rail becomes a pile body, and the pile is mainly supported by the rail to bear the bending moment.Scope: suitable for highway, municipal, railway, housing construction and other soft foundation and all kinds of landslide reinforcement.
Q:What is the method of rail butt welding?
The replacement of rail in CWR on the main line and no conditions for pressure welding or contact welding, the general method of aluminium heat welding rail, the disadvantage of this approach is that the solder joint residual impurities and bubbles easily, affect the service life of the rail and road safety, so in the solder joint al heat welding on general drum to install packet fishplate support as external reinforcement joint.
Q:High speed rail runs so many trains a day, what about rail wear?
The rail is made of high manganese steel.Manganese iron is very eccentric and interesting: if 2-3% manganese is added into the steel, the resulting low manganese steel is as brittle as glass and cracked at one stroke. However, if manganese is added to >13% to make high manganese steel, it becomes hard and tough.
Q:Discontinuous rail seamless rail effect
The rail welding seamless rail is 25 meters long up into several hundred meters or even thousands of meters long, and then put on the roadbed, seamless rail gap of 11 mm between each segment. Seamless rail is seamed, will also be affected.
Q:What is the rail of the railway?
Also, in the upper rail, the layer and is contacted with a wheel, is adding another metal, indium, it added to the rail on the part of the hardness of the case, even has some toughness, the train wheel is very important, it and the "tire" contact, the collision, there will be some flexibility, to ensure the safe operation of the train.
Q:What is the welding method of rail butt joint?
In order to adjust the melt temperature and the chemical composition of weld metal and alloy, often adding additives amount in thermites. Thermit welding has the characteristics of simple equipment, convenient operation and no power supply. It is often used in welding of rails, bars and other large section workpieces.
Q:What is the difference between rail welding and field welding of railway rails?
Field welding, usually in the workshop, the first 12.5 meters of track welding, welding into hundreds of meters, or even kilometers long track welding.
