Gr2 titanium elbow

One example of the application of Gr2 titanium elbow in chlor alkali plants is the use of titanium piping systems for the transportation of caustic soda and other corrosive chemicals.

In a chloralkali plant, the caustic soda solution is typically produced through the electrolysis of brine in an electrolytic cell. The caustic soda solution is then concentrated in a series of evaporators before being transported to storage tanks or further processing units. The transportation of the caustic soda solution requires a piping system that can withstand the highly corrosive nature of the solution.

Gr2 titanium elbows are often used in the piping system due to their excellent corrosion resistance and durability. They can be used to connect straight sections of piping, change the direction of flow, and adjust the angle of the pipeline. Additionally, the use of titanium piping systems can help reduce maintenance costs and improve plant efficiency by minimizing the risk of leaks and downtime.

There are many other applications of Gr2 titanium elbows in chlor alkali plants, including the construction of heat exchangers, reactors, and other process equipment. The use of titanium can help improve the overall performance and longevity of these systems, ultimately contributing to the success and profitability of the chlor alkali plant.

Specification

Titanium elbows made of Grade 2 (Ti Gr.2) titanium are commonly used in chloralkali plants due to their excellent corrosion resistance and high strength-to-weight ratio. Here are some specifications for titanium elbows made of Ti Gr.2 alloy:

• Elbow type: 45-degree elbow, 90-degree elbow
• Material: Titanium Grade 2
• Standard: ASTM B363, ASME SB363
• Diameter: 1/2″ – 48″ (DN15 – DN1200)
• Wall thickness: SCH 5 – SCH 160
• Bend radius: R = 3D, 4D, 5D, 6D, 7D, 8D, 9D, 10D, etc.
• Connection method: Welding or flanged connection
• Surface finish: Polished, pickling, sandblasting

It should be noted that the specifications and dimensions of titanium elbows may vary depending on specific process requirements and applications. Additionally, the welding process for titanium requires specialized techniques and equipment to avoid contamination and ensure high-quality welds.

Process

The process for manufacturing Gr2 titanium elbow for use in chlor alkali plants typically involves the following steps:

1. Raw material preparation: High-quality Gr2 titanium is sourced and inspected to ensure it meets the required specifications for the application.
2. Cutting and shaping: The titanium is cut into the required lengths and shapes using saws, shears, or other cutting tools. The material is then shaped using bending machines or hydraulic presses to form the elbow.
3. Forming and welding: The formed titanium elbow is then welded together using TIG (tungsten inert gas) welding or another suitable welding process. The welding is done in a controlled environment to minimize the risk of contamination and ensure the integrity of the weld.
4. Inspection and testing: The finished titanium elbow is subjected to rigorous testing and inspection to ensure it meets the required specifications for the application. This may include visual inspection, ultrasonic testing, and pressure testing.
5. Finishing: The titanium elbow is polished or sandblasted to improve its durability and resistance to corrosion.
6. Packaging and shipping: The finished titanium elbow is packaged and shipped to the customer or installed at the chloralkali plant as required.
