Rail Plastic Sleeve for Screw Spike

Introduction

Railway plastic sleeve, also known as plastic spike sleeve, plastic plug, concrete plug, etc., is a plastic part widely used in railway fastening systems.

Use

As a matching component of threaded spike, pre-inserted into the concrete sleeper. When railway fastening systems are used, the plastic sleeve serves as the fastening base and is matched with threaded spikes to ensure the stability and safety of the track.

Advantages

Good elasticity

the plastic sleeve has a certain elasticity and can adapt to the small deformation of the track, so as to maintain the stability of the fastening force.

Good insulation performance

Due to its material characteristics, the plastic sleeve has good insulation performance, which helps to prevent damage caused by current through the track and sleeper.

Strong weather resistance

plastic sleeve can resist a variety of adverse weather conditions, such as high temperature, low temperature, humidity, etc., to maintain long-term stable performance.
