FAQ:

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

A1: All products offered by OKorder.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: What makes stainless steel stainless?

A2: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.

Q3: Can stainless steel rust?

A3: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface.

Q:Why can the single phase of catenary be used? Why is rail used as loop without electricity?
Commonly used FireWire, relative to the earth, there is voltage, so people standing on the ground will feel electric shock, when standing on the insulating object, it will not get an electric shockIsolated 220V, standing on the ground and touching one of them has nothing to do with it
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 connection of the rail joint?
The intermediate connecting parts, also called fasteners, have different combinations according to the different types of sleepers used. The wooden, including ordinary spike and iron plate. The advantage of this kind of fastener is less parts, easy installation, but little effort. In order to improve the performance of wooden, many countries use screw spike or spring instead of ordinary spike spike, or use a variety of different types of fastener on the concrete sleeper has been effective. The concrete sleeper fastening, including anchor bolts, iron plate, fastening piece and an elastic cushion (a) anchor bolt. For fastening fastening parts by anchoring various methods. The use of China on the railway is a sulfur anchor mix of sulphur, sand, cement and wax mixture is melted into colloid, injected into the reserved hole in the sleeper, as the fixed anchor bolt medium, pulling resistance, durability and insulation performance are very good. (b) iron backing plate. The utility model can disperse the vertical pressure of the rail, and after adding the shoulder, the transverse force transmitted by the rail can be partly taken, but because the compressive strength of the concrete sleeper is very large, the utility model can not be arranged in general. (c) fastening parts. There are two types of rigidity and elasticity. Rigid fastening parts mainly for buckle type; elastic fastening parts are spring and bar use plate elastic strip type two. (d) elastic cushion. When the train passes, the utility model can buffer and reduce vibration, and can improve the insulation performance of the concrete sleeper. Rubber backing plate, plastic backing plate, cork rubber backing plate and wood backing plate etc., and rubber backing plate is the best.
Q:What is called orbital angle?
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. The rail can be divided into three kinds: crane rail (crane track), heavy rail and light rail.
Q:Contact surface between train wheel and rail
The two wheel with the rail on the inside, the country for the axle, in the gold processing, the axis of the two end will leave about 50 wire axis file, so that after the bearing is installed, it will not continue to slide inside, play a fixed role, the outer end with nut tightening
Q:Name the basic structure and function of the rail
These types of rail, rail 38kg/m has stopped production, 60kg/m, 50kg/m rail on the main line and the dedicated line laying, laying rail general 43kg/m. For heavy haul railways and specially busy sections of railways, the 75kg/m rail is laid.In addition, in order to meet the requirements of switches, super large bridges and jointless track structures, special rail sections (with asymmetrical central axis) are adopted in our railways. Now we use more special short section rail, referred to as AT rail.
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:What's the difference between a high-speed rail and an ordinary one?
The weight is different, generally with 60 rail; the ballast is different, choose a different grade washing granite; type three sleeper, sleeper for general use
Q:Structural classification of rails
These types of rail, rail 38kg/m has stopped production, 60kg/m, 50kg/m rail on the main line and the dedicated line laying, laying rail general 43kg/m. For heavy haul railways and specially busy sections of railways, the 75kg/m rail is laid.
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.
