Application of PR Clip

As one of the common railway fasteners in rail fastening system, PR clips are made of forged spring steel and have many applications in railroad. No matter as a part of railway fastening system or as a railway fastener, PR clips are used together with other railway components, such as rail spike, rail tie plate, rail pad and rail plastic dowel. In the railway fastening system, the main function of railway clip is fastening railway sleeper and steel rail together. The railway clip is considered as one of the best ways to ensure that steel rails not move, bend, warp, or rot. There are data shows that each PR clip can bear about two tons of force upon a railway track.

Production Process of PR Clip

Raw materials: Long-term high-quality spring steel from reliable and certified manufacturers.
Cut: Spring bars must be cut to the required length.
Heating: Forging temperature (950-1000 degrees Celsius), but overheating should be avoided to check for decarburization.
Forming: Appropriate heating rods should be transferred to the forging press.
Hardening: The forged rail clamps are moved to the quench tank. Check the dimensional accuracy and quench hardness of the rail clamps before tempering.
Tempered: The rail clamps are tempered at approximately 350 degrees Celsius to achieve proper toughness in the spring.
An examination: Products are thoroughly inspected according to the specifications and designs customer requirements.

Precautions for Use PR Clip

First, regular inspections are required to ensure the clips are working properly. This may involve checking for any signs of wear, corrosion or damage that may have occurred during use. Once problems are discovered, quick action should be taken to repair or replace the spring bars to avoid safety hazards.

Secondly, it is important to keep the PR clips clean to prevent dust and debris from accumulating, which can lead to failure or corrosion. It is recommended to use a brush to remove any loose dirt particles, then wipe the clamp with a clean cloth or use compressed air to blow away stubborn dirt.

Lubrication is also important to prevent rust and corrosion on the clips. The clamps should be coated with a good quality lubricant to keep them in good condition. However, it is important to use the proper lubricant that is compatible with the PR clips and rails.
