Titanium and Titanium Alloy Welded Pipe

Titanium alloy welded tube is a titanium metal tube made of high-purity titanium strip or titanium plate through rolling and automatic welding. Compared with traditional seamless titanium tube, welded titanium tube has higher dimensional consistency, lower production cost, and can be customized in length, wall thickness and material. It is widely used in high-end fields such as chemical corrosion protection, heat exchangers, seawater desalination, medical equipment, aerospace, etc.

Chalcotitanium titanium alloy welded pipe production, processing and quality assurance

• Supports multiple processes such as TIG, PAW, laser welding, etc., and automated welding is stable and efficient.
• The pure argon shielded welding process is suitable for wide and thick titanium plates and large diameter welding.
• After welding, cold rolling or hot rolling finishing can be carried out to improve the accuracy and uniformity of the pipe.
• Use controlled atmosphere annealing to prevent oxidation, relieve stress and improve overall stability.
• Provide a variety of surface treatments such as pickling and electrolytic polishing to meet high-cleanliness applications.
• The weld is full and smooth, with a small heat-affected zone, and has excellent strength and appearance consistency.
• The welds can be subjected to non-destructive testing such as X-ray and ultrasonic testing to ensure the safety and reliability of the structure.

Chalcotitanium titanium alloy welded pipe application cooperation areas

Chalcotitanium welded pipe for heat exchanger manufacturing

Compared with seamless pipes, welded pipes are easier to control in length and wall thickness, are particularly suitable for large-scale, standardized production, and are more cost-effective.

Chalcotitanium offers custom OD/wall thickness combinations with tight tolerances (±0.10mm), annealing and pickling, and full weld inspection reports to ensure heat transfer efficiency and long-term reliability.

Chalcotitanium welded pipe for chemical industry/petrochemical industry

Corrosion-resistant titanium alloys such as Gr7 and Gr12 are often used for conveying corrosive media. Welded pipes can be adapted to larger diameters or special structures by means of splicing/thickening.

Chalcotitanium provides multi-pass welding and thick plate welding capabilities, has a stock of corrosion-resistant alloys such as Gr7/Gr12, supports third-party testing and can customize complex structures according to drawings.

Chalcotitanium welded pipe for seawater desalination and marine engineering

In salt spray, high humidity and high corrosion environments, titanium alloy welded pipes have the advantages of light weight and high strength. At the same time, they can achieve ultra-long structural welding and reduce flange connection points.

Chalcotitanium provides extra-long structural pipes (6m+), butt welding capabilities, anti-oxidation annealing treatment and comprehensive non-destructive testing to meet offshore grade requirements.

Chalcotitanium welded pipe for medical/pharmaceutical industry

In situations with high cleanliness requirements, welded pipes can achieve smooth inner walls and customized surface treatment to meet the requirements of cleaning processes such as CIP/SIP.

Chalcotitanium provides internal and external pickling and polishing, low roughness control, seamless weld treatment and full process traceability material report to meet high cleanliness applications.

Titanium Welded Pipe Product Selection Guide

1. Welded pipe vs seamless pipe: How to choose?

If you are concerned about dimensional accuracy, cost efficiency, and the application pressure requirements are not extreme, welded titanium tubes are more preferred.

2. How to evaluate whether the price of titanium welded pipe is reasonable?

The price of titanium welded pipes is determined by alloy grade, size, additional processes and order quantity. For example, alloys such as Gr5 and Gr7 are more expensive, and custom pipes, annealing or non-destructive testing will also increase the unit price. Note: Low-priced products may not be annealed or use recycled materials. It is recommended to verify the quality control process and material source.

3. How to choose a reliable titanium welded pipe supplier?

Priority is given to manufacturers with integrated welding, annealing and testing capabilities. We support customized special-shaped tubes and long tube sections, issue complete quality assurance documents, have rich export experience, and can respond quickly to various needs. It is recommended to first test the process stability with a sample or a small batch.

4. Confirm welding quality and inspection standards?

The welds should be subjected to X-ray or ultrasonic nondestructive testing, and airtightness/water pressure testing should be performed if necessary. All our products can be annealed, and post-processing such as weld cleaning and pickling is provided, and material reports and test data are attached to ensure reliability.

5. Do you need a custom shape or length?

We can produce square tubes, rectangular tubes, oval tubes and other special-shaped cross-section tubes, supporting welding of super-long structures, composite structures and customized sizes. Welcome to provide drawings, we will quickly evaluate the feasibility and assist in proofing.
