Compromise joint bars

Rail Joints, other names are railway fish plate and splice bar, joint bar and angle bar. it is a metal joint bar functions by connecting the ends of two rails sectoins together with rail bolt. 

Rail fish plate can increase the continuity and steadiness for track sections when the train is passing through by largely reduce the impact of wheels to the jointing sections of the rail tracks. This rail connectiong component is a key part for railroad transportation safety insurance.

Compromise joint bars customised in Kunshan Alex Railway Fastening Co.,ltd

Compromise joint bars are one kind of special rail joint bar. As we know, normal rail joint bars are the components involved in railway applications that connect different sections of rails together while maintaining gauge and keeping the alignment of rail surfaces. Unlike normal rail joint bar, compromise joint bars are used for joints of abnormal rails.

There are two kinds of compromise joints:

Directional (Right or Left hand) compromise rail joint bar is used where a difference in the width of the head between two sections requires the offsetting of the rail to align the gauge side of the rail.

Non-directional (Gauge or Field Side) joint bar is used where the difference between sections is only in the heights of the head or where the difference in width of rail head is not more than 1/8" at the gauge point. Gauge point is the spot on the gauge side of the rail exactly 5/8" below the top of the rail.

Kunshan Alex Railway Fastening Co.,Ltd has more than 13 years of technology in manufacturing rail fish plate in almost all standards such as BS, ASTM and DIN, and others. We have exported all types of fish plate for various applications, quality has been tested and approved by South American, European and Southeast Asian markets and in China mainland.

We have the capability to manufacture all types of rail fish plate to suit all types of rail sections, such as UIC 60, UIC 54, U33, BS 80A, BS 90A, IRS 52 KG, IRS 90 Lbs, 115 RE, 136 RE, TJ 45, TJ 37, RN 45, etc.

Just send us the detailed dimensions of your required rail fish plates/ rail joints,  or if you don't have drawing, please send us a sample for checking and making drawing for you, then we'll do the rest.

Quality Control of Compromise joint bars

Quality of ALEX rail joints is guaranteed by a special heat treatment. When the train is running, rail joints (railway fish plates) play an important role in connecting and fastening rails as well as keeping the integrity of rails. While the speed and load of rails are increasing, it requires a higher performance to the property of rail joints. 

A rail joint can connect two rails with six bolts. Relying on the up and down shoulder slopes and the fastening with rails, it can support the large load during the train’s runtime, the fretting wear and other complex stresses.

The property of railway joints always changes with the rate of cooling. What's more, during the heat treatment , the hardness and the impact of rail joints can be different according to the degree of water quenching.

After pouring were conducted, two types of the process which are called immediate quenching and tempering processes can give out some important information. Because of the slow drop of temperature, it can lead to a high degree of the hardness. So the mechanical property of rail joint becomes more advantageous.
