Customization of Post Tensioning Wedge

In order to meet different requirements of our customers and as we have R&D team to develop, RuiYi provides many customization products to our customers.

For example, if you have only an idea of the diameter of the PC strand, we could provide you professional advice and drawings of anchor and wedge that could be workable for your confirmation.

If you have drawings, RuiYi could provide OEM service for your products with good quality control and reasonable cost.

If you have real samples, an equal sample could be made for your confirmation.

The customization process usually is: Primary communication-drawings produce-drawings confirmation-sample production-sample confirmation-production and there will be certain sample cost according to the difficulty of making.

Production Process of Post Tensioning Wedge

The wedge production includes 8 parts, which are:

● Cutting-raw material 20CrMnTi Bars are cut into small pillars as required.

● Forging-After cutting, it will be punched central holes by CNC forging machine.

● Engraving-After forging, it will be cut to required size and angle by CNC engraving machines.

● Tapping-after engraving, it will be tapped to certain thread shape and size as required.

● Splitting-After tapping, it will be cut into 3 or 2 pcs as required.

● Heat Treatment-After splitting, it will be heat treatment at 890℃.

● Assembling-After treatment, it will be inspected and assembled by auto machine.

● Packing-Finally, it will be packed into box or bucket as per requirements.

Heat Treatment System

 

Customized Post Tensioning Wedge

 

Heat treatment includes:

1. Annealing: The workpiece is heated to an appropriate temperature, different holding times are adopted according to the material and workpiece size, and then slowly cooled, in order to make the internal structure of the metal reach or close to equilibrium, obtain good process performance and use performance, or prepare the organization for further quenching.

2. Normalized: The purpose of normalizing is to eliminate the segregation phenomenon caused by process or other problems in the rolling process of steel plate; Attack removes internal stress from the material; Reduce the hardness of the material.

3. Quenching: A metal heat treatment process in which the metal workpiece is heated to an appropriate temperature and held for a period of time, and then immersed in a quenched medium for rapid cooling.

4. Tempering: A metal heat treatment process in which the quenched workpiece is reheated to an appropriate temperature below the lower critical temperature Ac1 (the starting temperature of pearlite to austenite transition when heating), and cooled in air or water, oil and other media after a period of heat retention.

With heat treatment process, the product surface can reach required hardness. To ensure that, RuiYi use Euro vacuum oven and carburization at 890℃ for 7 hours and this process is totally controlled by ourselves. So it give us the advantage that the quality control system is a whole closed circle. And we could control the quality and cost better. The size of oven mouth is 150×90×120cm, which can treat 100,000 sets of wedge per day to fulfill the demand of our customers.

 

Quality Inspection

Our company possesses a comprehensive quality inspection process, quality control equipment, and testing standards.

1. Raw material Inspection-Checking the raw material report of supplier.

2. Inspection after Cutting-Weight inspection after cutting.

3. Inspection after Engraving-Size and shape inspection of product.

4. Inspection after Splitting-Size and shape inspection of thread.

5. Inspection after heat Treatment-Hardness inspection.

6. Inspection before packing-Auto machine inspection.

Considerations for Selecting Post Tensioning Wedge

1. Material Selection: Post Tensioning Wedges are typically made from 20CrMnTi. You should choose high-quality plates that offer good durability, sufficient elasticity, and the ability to withstand prestressing forces.

2. Plate Size and Shape: Select appropriate plate sizes and shapes based on specific structural requirements. The dimensions and shape of the plates should align with the layout of prestressing tendons and the design of the components.

3. Installation and Adjustment: Proper installation and adjustment of Post Tensioning Wedge are crucial to ensure the desired prestressing effect in the structure. Ensure that the Wedge fit smoothly onto the concrete components and can withstand and transmit prestressing forces.

4. Quality Control: Quality control of the Wedges is of utmost importance. Ensure that the Wedges adhere to relevant specifications and standards. Collaborate with suppliers who participate in qualification certifications to ensure the quality and reliability of the products.

5. Maintenance and Inspection: Regularly maintain and inspect the Wedges to ensure their proper functioning during usage. Check for signs of cracks, aging, or other damage, and replace them when necessary.

Post Tensioning Wedges play a crucial role in prestressed concrete structures. Therefore, it's essential to pay special attention to quality and technical requirements when selecting, installing, and maintaining these Wedges.
Collaborating with professionals and adhering to relevant design specifications and recommendations can ensure the effectiveness and reliability of the Post Tensioning Wedge system. Contact us now!
