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:Why rail interface with?
The scientists measured the temperature of the rails at 1 degrees, and the length of the rails varied by 1.8 microns per metre. If there is no gap in the rail connection, the rail will be extruded, twisted and arched, so that the whole railway will be deformed.
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:Generally, how often do rail rails change?
This depends on the line conditions, such as the Daqin Line Heavy Haul lines, because each year the volume can reach 7 tons, generally less than a year to track, on the small radius curve rail replacement cycle is shorter, for many reasons, such as serious abrasion, stripping off block etc..
Q:Scrap rail has what use, what enterprise demand on rail?
The use of the old rail companies generally require coal mine tunnel laying railway enterprise, and gantry crane, crane installation, also need to track than with new rail can save much cost, use effect can be said to be the same. The waste rail can only be used as heavy steel scrap into the steel enterprise.
Q:What is the rail temperature stress?
The rail temperature stress is that the rail will expand and contract when the temperature changes. It is bound by the fastener and the internal force.
Q:What kind of rail needs polishing?
Corrective sanding (defect grinding) (Figure 2)The main purpose of this strategy is to eliminate or reduce grinding defects on line rail, generally use the active grinding process, pre designed grinding amount (0.5mm to 4-6mm), and the interval is relatively long, usually by the severity of the defect to decide.Corrective grinding is not very economical, mainly because of the need to remove a large amount of metal on the rail surface, and also requires a large number of grinding processes to reduce the potential service life of the rail. But to ensure that the rail will not fail in a short time, corrective grinding is necessary, especially during the period when the budget for replacing rails is tight. However, this condition of the rail may cause the train speed limit.
Q:Contact surface between train wheel and rail
Because the wheels of the train all have rims, you can go and have a look at it, that is, a part of the inside of the wheel. The main function of this wheel flange is to guide and prevent derailment. The rim has a very complex profile. The standard requirement is that if the flange of a car is too worn out, it is prone to derailment. The machined flange must be machined to the standard contour.
Q:What is the difference between Q235B rail and 55Q rail?
The 55Q material is mainly used for mine rail, while another is more commonly used, such as the use of no special requirements on the selection of Q235, another reason is that the price is also a cheaper one.
Q:What is the cause of the side or rail end of the rail? If not timely remediation, what will easily lead to consequences?
This is one kind of disease. In the long run, the rail profile will be out of shape with the standard profile, which may cause the contact point deviation of the wheel tread and make the band widen or narrow or not. Causes sway, noise, and reduces ride comfort. Of course, the speed can not be raised.
Q:Why should there be a certain gap in the rail connection?
Now there are many high-speed railways have adopted the technology of seamless rail, they put the original welding gap between the rails, which no longer had left the gap between the tracks and the train tracks, running is stable, but also greatly reduces the noise between wheel and rail.
