Fastening System E Clips

Railway Clip is used to fasten the rails to the underlying base plate together with the concrete sleeper. A variety of different types of heavy-duty clips are used to fasten the rails to the underlying baseplate or Sleeper, one common being the E Clip, which is shaped like a stubby paperclip. Another one is the SKL Tension Clamp, which is also the most widely used type all over the world. Others like KPO Clamp and Nabla Clip, also used in different situations.

Description

Technical Parameters

↵Rail E Clip Fastening System

The Railway E-Clip is a pre-assembled elastic rail fastening system characterized by its distinctive "E" profile when installed, integrating the spring clip, insulator, and shoulder into a single polymer-steel composite unit. This clip achieves its elastic function through controlled bending of its parallel arms rather than torsional deformation, creating a unique stiffness profile that combines high initial clamping force with progressive resistance characteristics. As a flagship product of modern "unitized" fastening philosophy, it eliminates field assembly errors while offering predictable long-term performance across diverse climatic and loading conditions.

Functional & Engineering Perspective

Moisture Absorption Compensation: Nylon's inherent hygroscopicity (2-3% moisture absorption) is engineered to create beneficial swelling that maintains interface pressure during dry/wet cycles, with moisture distribution modeled to prevent warpage.

Fire Performance Engineering: The composite meets EN 45545-2 R22 requirements through aluminum trihydrate fillers (40-50 wt%) that release water vapor at 200-300°C while maintaining structural integrity up to 180°C for 30 minutes.

Maintenance & Operational Perspective

Controlled Failure Progression: Under extreme overload, failure occurs in stages: 1) polymer housing cracks (120-150% design load), 2) steel clip plastic deformation (180-200% load), 3) complete disengagement (250-300% load)-each stage providing warning and maintaining some residual function.
Corrosion Protection Redundancy: Three independent barriers protect the steel insert: zinc-nickel plating (12-15 μm), epoxy primer (15-20 μm), and complete polymer encapsulation (2-3 mm nominal), creating estimated 50+ year corrosion life in chloride environments.
Creep Resistance Engineering: The polymer formulation includes nano-clay additives (2-3 wt%) that reduce creep deformation by 60-70% compared to standard nylon, maintaining dimensional stability under sustained load at elevated temperatures.
