Product Description
Rail shoulder, also called rail iron shoulder, is mainly used to be casted in the concrete ties to fixate elastic rail clips. According to the shape, it can be classified into Single Stem Rail Iron Shoulder and Twin Stems Rail Iron Shoulder. Besides, according to the manufacturing ways, rail shoulder can be divided into 3 types: casting rail shoulder, weld-on rail shoulder and hot forging rail shoulder.
The rail shoulder is embedded in concrete at the time of casting, it's used to grips the clip effectively and provides lateral support to rail.
The Rail shoulder is semi-embedded part cast in the concrete rail ties to fix the elastic rail clip to the base plate. There are two common types of rail shoulders available: Cast-in Shoulder and Weld-on Shoulder, both of which are used for the fixing of elastic rail clips. One is Single Stem Iron Shoulder used in pre-stressed concrete ties and the other is Twin Stem Iron Shoulder used in Bi-Block or Twin Block concrete ties.
Quality Control System
All processes are in accordance with the requirements of ISO quality management system, from supplier quality control to finished products. We maintain a strict quality control system:
01
Raw Material Inspection: Before producing Rail Shoulder, we will check and test the raw materials. We require production batch numbers, chemical composition, and mechanical properties.
02
Batch Testing: Quality control inspectors take samples and perform batch testing after manufacturing, providing raw material certificates to control the testing process.
03
Physical & Chemical Testing: According to specific requirements, we conduct corresponding physical and chemical inspections. Materials are only accepted if they meet our rigorous standards.
04
Coordination & Guidance: For semi-finished products, we organize quality control coordination meetings and provide technical guidance to ensure qualified products are delivered.
Frequently Asked Questions
Q1: What is the primary function of a rail shoulder?
A: Rail shoulders are primarily used to be cast into concrete ties to securely fixate elastic rail clips, providing essential lateral support to the rail.
Q2: What are the different types of rail shoulders based on manufacturing?
A: There are three main types based on manufacturing: casting rail shoulders, weld-on rail shoulders, and hot forging rail shoulders.
Q3: What is the difference between single stem and twin stem shoulders?
A: Single stem iron shoulders are typically used in pre-stressed concrete ties, while twin stem iron shoulders are designed for Bi-Block or Twin Block concrete ties.
Q4: How do you ensure the quality of the raw materials?
A: We check chemical composition and mechanical properties, requiring suppliers to provide production batch numbers and testing indicators before production begins.
Q5: Is the production environment-friendly?
A: Yes, our rail shoulders meet environmental standards and are classified as environmental friendly.
Q6: What certifications do your production processes hold?
A: All manufacturing and quality control processes are in accordance with ISO 9001 standards.
