Each standard rail joint of other types (bulge, compromise, insulated, glued insulated) are also available!

Compromise Rail Joint

Compromise joint bar is used for connecting two different rail sections, it can connect them exactly and make the whole track flat and smooth. The compromise rail joints we produce use high strength steel and made by advanced precise machine, it has precise specification and fit the rails exactly. A compromise is composed of two bars: gauge side joint bar and outside joint bar.

How to choose suitable compromise rail joint?

If you want to order right compromise rail joint, the specification of both rail sections and the following dimensions of rail joint you need must be clear.

  • A - The end of the rail to center-line of first hole.
  • B - Center-line of first hole, to center-line of second.
  • C - Center-line of second hole, to center-line of third hole (where 6-hole bars are used).
  • D - Diameter of bolt hole (or bolt size).
  • E - Elevation of bolt hole (center-line of bolt hole above base) on non-standard rail.

We can manufacture different specifications of compromise joint bar according to your drawings and samples.

Joggled Rail Joint

Bulge rail joint, also called bulge rail joint, has a bulge section in the middle of the joint bar, and it can fasten the steel rails tightly. Bulge rail joint is usually used in broken welded rails or temporary repair of cracked welded rail joint with an emergency clamp. It can suit for various rail sections and enable quick and temporary repair, guaranteeing the continuous movement in rail track.

Insulated Rail Joint

Insulated rail joint are usually used for electrical resistance in railway track. It contains insulation materials wrapped or bolted around contacting surface the rail track which can control signaling and broken rail identification systems. The end post of Insulated rail joint can be classified into two types: inserted end post and glued end post.

Insulated rail joint component:

  • Two rail sections
  • One end post
  • Two rail joints
  • Six (or four) bolts, nuts & washers
  • Electrical insulation material sheets

Glued Insulated Rail Joint

Glued insulated rail joints are used in long welded rails for insulation. The glued surface can provide mechanical strength for the extension and compression of the rails because of the pressure from the vehicles. It is usually used in track-circuited area for insulation of the rails to adjacent rails in continuous welded rail sections. Glued insulated rail joint is easy to install with minimum number of the installing components. We have advanced modern manufacturing machines for rail joint, so the quality is guaranteed with high fatigue properties.
Top Features of Glued Insulated Rail Joint

  1. Glued insulated rail joint never subject to the changes in temperature and the temporary pressures forced by the rails and rail joint. Non-glued joint structure is not ideal in this aspect.
  2. The insulating material is glued in the gap of two steel rails, which not only strengths the stiffness of the rails, but provides continuous welded rails for the vehicle.
  3. The using of GIRs prolongs the service life steel rail and improves the travelling comfort.
