What is steel rails standard?

 What is steel rails standard?



Steel rail also called rail track, is a vital part of the railway track system. Steel rail undertakes the task of guiding the train wheel and transferring load from locomotive to railway sleeper. As an essential component of railway track structure, the quality and material of steel rail directly impact the safety and service life of railway tracks. For choosing high-quality steel rail, it is necessary to learn two questions: what is the standard for processing steel rail? And how steel rails are made? Today, we’ll discuss the first one—what is the standard for processing steel rail?

Steel rails standard in various countries

As for the standard of steel rail, to meet different requirements of different countries, there are many international standards for steel rail on the market. The common standards include AREMA, UIC, JIS, BS, GB, Russian standards, etc.

AREMA steel rails standard

AREMA standard was formulated by the American Railway Engineering and Maintenance of Way Association. American standard railway products especially steel rail generally adopt the AREMA standard. Common types include AREMA 115, 119, 132, 133, 136, 147. And so on.

Russian steel rails standard

Russian standard steel rails

There are three standards for Russian steel rail: ГOCT 24182-80， ГOCT 18267-82, and ГOCT 51685-2000. They are designed for different steel, ГOCT 24182-80 is the standard for hot-rolled rails, and ГOCT 18267-82 is for heat-treated rails. GOST P 65kg is a typical type of Russian standard steel rail.

JIS steel rails standard

 

JIS standard is suitable for Japanese standard railway tracks. Japanese standard steel rail has a low technical requirement, but a high production level. JIS standards for rail list as below:

JIS E1101: hot-rolled rails

JIS E1123: heat-treated end of rails

JIS E 1120—1994: Heat-treated rails

Normal JIS standard steel rail includes JIS 37kg, 40kg, 50kg, 60kg and etc.

UIC steel rails standard

UIC is the International Union of Railway steel rail standard. UIC standard is one of the popular widely standards, many countries adopt this kind of standard to choose steel rails. UIC 54 and UIC60 are two common types.

BS standard steel rails

BS standard is short of British standard. Obviously, the BS standard is mainly used for the British railway track. Ordinary types of BS standard steel rail include BS 70, 75, 80, 90, 100, etc.

European  steel rails standard

The European standard is one of the most advanced and strict standards for steel rail in the world. prEN13674-1：2002（E）and prEN13674-2:2003(E) are two parts of European standards, the latter mainly set rules for railway switches. Besides, the European standard is designed for the high-speed railway.

GB steel rails standard

It is standardly used for the Chinese railway. GB standard covers many types of railway track, such as hot-rolled rail, heat-treated rail, and rail for the switch, all these steel rails can be applied in the mph 200 or 350 passenger railway, mph 160 or 200 railway, etc. common GB standard steel rail include GB 43, 50, 60, 75 and etc.

What are railway rail fasteners？

What are railway rail fasteners？ Railway rail fasteners Railway rail fasteners are a kind of railway accessories. The parts used to combine rails and sleepers (or other types of under-rail foundations) on the track are also called central joint parts. Its function is to fix the steel rail on the sleeper, maintain the gauge and prevent the longitudinal and lateral movement of the rail relative to the sleeper. The railway rail fastener system is divided into the shrapnel fastener system, gusset fastener system, and elastic strip fastener system. The gusset-type fastener is composed of a gusset plate, a threaded spike, a spring washer, an iron seat, and a buffer pad. The threaded spike is anchored in the reserved hole of the concrete sleeper bearing platform with sulfur cement mortar, and then bolts are used to fasten the buckle. Plate fastened. There are elastic strips I, II, and III types of clip fasteners. Type I elastic strip is composed of ω elastic strip,  screw spike , gauge b...
