Invoicing on theoretical weight or actual weight as customer request

Payment terms: 30% advance payment by T/T, 70% payment against the copy of the B/L; 100% L/C at sight, etc.

Applications of Heavy Rail

Heavy rail is suitable for the laying of main trunk line of the curves and the orbit of the tunnel can also be used for tower crane and other crane track. Be used for railway, subway, curve way, tunnel way, etc.

Packaging & Delivery of Heavy Rail

1. Packing: it is nude packed in bundles by steel wire rod

2. Bundle weight: not more than 3.5MT for bulk vessel; less than 3 MT for container load

Heavy Rail   

3. Marks:

Color marking: There will be color marking on both end of the bundle for the cargo delivered by bulk vessel. That makes it easily to distinguish at the destination port.

Tag mark: there will be tag mark tied up on the bundles. The information usually including supplier logo and name, product name, made in China, shipping marks and other information request by the customer.

If loading by container the marking is not needed, but we will prepare it as customer request.

4. Transportation: the goods are delivered by truck from mill to loading port, the maximum quantity can be loaded is around 40MTs by each truck. If the order quantity cannot reach the full truck loaded, the transportation cost per ton will be little higher than full load.

5. Delivered by container or bulk vessel

Heavy Rail

6. Delivery Time: All the Hot Rolled Steel Rail will be transpoted at the port of Tianjin, China within 30 days after receiving the advance payment by T/T or the orginal L/C at sight.

Inspection of Heavy Rail

We will send the MTC of the factory to the clients dirrectly which contain the anlisis of the heat, chemiqul composition, phisical characteristicas, etc.

And our inspectors will arrive at the factory to meke the inspection of the size, length, weight and quantity before the transportation from the factory.

Q:What kind of welding rod should be used for rail and Q235A welding?
MG600 is a universal, high efficiency, high strength chromium nickel alloy welding rod (welding wire). It has excellent plasticity, toughness and crack resistance. It is almost suitable for all kinds of common steel products. With excellent welding process performance, arc stability, easy to slag, less spatter, welding uniform and beautiful.
Q:What is the rail temperature stress?
Thermal stress is also called thermal stress". Stress due to the temperature rise and fall of a body or the temperature of each part of an object. For example, the workpiece is welded by the stress caused by local heating; there is a gap between the rails of the rails to avoid or reduce the possible temperature stress.
Q:Several questions about high speed rail and subgrade.
You said in front of the concrete board has already said is the track board, the following "cushion" should refer to the CA mortar filling layer, that is, cement, asphalt, mortar layer. The main function is to support the track plate, to buffer the load and shock absorption of the high speed train. The main materials are: cement, emulsified asphalt, fine aggregate, water and a variety of additives. The edge breakage has no direct effect on its performance, but in the long run there must be some adverse effects, especially the ageing resistance.
Q:The rail line orbit must use different types of profiled rail connection
The sizes of different types of rails are different. To ensure the reliable connection between the two types of rails and the top of rail, the special-shaped joints must be used.
Q:Why does the train not skid on the rails?
For example, calculation of the adhesion coefficient of domestic DC electric locomotive according to formula j=0.24+ (12/ (100+8v)), which is mainly for freight locomotives, passenger locomotive traction tonnage due to smaller, generally have relatively small, probably between 0.2-0.3.
Q:Why is the railroad track free of expansion joints now?
Seamless rail not thousands of kilometers without gaps, but the 25 meter long rail welding up into hundreds of metres long or even thousands of meters long, and then in the shop on the embankment, or the gap between 11 mm and a section of a seamless rail, now Shanghai Nanjing line is 303 km long ultra long seamless rail, seamless rail in order to solve the thermal expansion and contraction by slot number is not enough, now there are two methods of thermal expansion and contraction
Q:What's the difference between a high-speed rail and an ordinary one?
Not only does the train speed run faster than the train, but the infrastructure (track, signal, communication and catenary) of the train also meets the technical requirements of the speed grade.
Q:What is the working principle of a rail profilometer?
Two dimensional scanning sensor ZLDS200 series is a small range, high speed and high precision two-dimensional sensor, with digital, integrated structure. The two-dimensional laser sensor ZLDS200 series with high precision can reach Z per second, 0.1% 1200 axis scanning contour data of high response and high degree of protection IP67, and synchronization characteristics of high performance, and in addition to the standard series of products, can also be customized according to the user's special needs.
Q:The rails of the high iron welded together as a whole
Seamless welding technology, can make between two rails almost can not see the welding point, natural transition, in the high-speed rail, "bang" sound will become history.
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.
