what is a rail joint?
Rail joint is a kind of railroad fasteners and plays important role in connecting the steel rail together with the help of fish bolt. There are many types and different standard rail joints according to various uses. GNEE RAIL can provide you with different rail joints such as GB, AREMA, BS, UIC, AS, African standard, South American standard, and different types such as common rail joint, compromise rail joint, bulge rail joint, insulated rail joint and glued insulated rail joint, etc. Our products have been exported to more than 20 countries and areas and more than 50 types of rail joints of standard and nonstandard are available for global customers.

Types of Rail Joints
According to the raw materials used, rail joints can be divided into ductile iron, Q235 type, and Q255 rolling type, forging type, etc. In general, medium and high-carbon steels are used as raw materials. According to different applications, rail joints can be divided into bolted rail joints, compromise rail joints, and insulated rail joints.
- Bolted rail joints
Bolted rail joints are the primary choice for slow-speed, light-transport railroads.
- Compromise rail joints
Compromise rail joints are needed when connecting two rails of different sizes. Unlike regular standard linear rail joints, compromise rail joint bars have irregular shapes.
- Insulated rail joints
Insulated rail joints are a new kind of track material made of high-strength composite material. Belong to thermosetting material, the insulated rail joints can't be reprocessed. Insulated rail joints can provide signals when the trains get to a position through electric isolation. Thus, it is widely used in the freight railroad to detect outages and control traffic jams.
Feature of insulated joints：
- Good insulation reliability.
- Lightweight and high strength.
- Suitable for a wide range of temperatures, good low-temperature resistance (-55℃~85℃).
- Good impact resistance and strong toughness.
- Good aging resistance and long service life.
- Water resistance, corrosion resistance, and good tolerance.
- Lightweight, easy to carry, convenient to install, time-saving and efficient.
- Maintenance-free insulation, high efficiency in troubleshooting.

How to do maintenance for rail joints ?
To ensure the fine use of railroad equipments, we need to maintain the rail joints from time to time in order to improve quality and avoid any accidents.
Assembling and maintenance standards for rail joints:
STEP1: Check if the bolts are well fastened and make sure no wounds or cracks on the surface
STEP 2: Keep each connected rod and locking device clear from cracks. No grinding or corrosion on the rod body or abrasion pin hole less than 1mm. Good insulation shall be maintained.
STEP 3: All iron rods' connection is with good insulation and the insulation link between lock iron and gauge rod are both fine. At uninsulated condition, 3mm gap should be kept and not into other parts. And bolts are fastened well.
STEP 4: Ensure no cracks on the shell of the switch machine to assembling rail joints, and the installation is firm under good lock condition.
STEP 5: Ensure the oil tank circuit in good protection without damage or being buried by ballasts or other debris.
