Rail insulated joints in USA are sometimes called fishplates as well. These joints are an integral component of a rail track system that connects two rail tracks together.
There are three types of rail joins such as:
• Bolted joints
• Compromise joints
• Insulated joints
The bolted joints are generally used to connect the rail tracks together before making them welded. Two rails are needed to be joined with different sections. In most of the cases, the compromise joints are used. On the other hand, the insulated joints act like the bonded or non-bonded joints. These three joints share some common functions as well.
These features are:
Bolts and the bars are all applied and an interruption is caused on the running of the surface of the rail track. The interruption or discontinuity can accelerate the track degradation around the rail joints while trains are running. Nowadays, the insulated rail joints can be found to as bonded insulated rail joints and polyurethane insulated rail joints. These bonded joints are generally used to divide electric circuits in rail and turnouts. While using this type of joints, it is important to ensure that the insulated joints are able to transfer longitudinal forces coming from the railway tracks because of the widely welded rails or CWR.
Let’s have a look at some of the features of joint bars:
• Up to 60’ long
• A-490 bolts or huck pins
• Worn in rail or transition rail configuration
• Micro alloy joint bar
You will get this type of insulated rail joints available at anywhere with four, six or eight holes. It is long lasted and the performance is really high. Only a reliable and experienced rail joint bar manufacturing company in USA should be preferred for such dealings as it involves countless lives. And no authority would like to take any risk with so many lives.
