Titanium Welding Coil

Our Titanium Welding Coil (also called welded titanium coil tubing) is a high-performance industrial tubing product, manufactured from high-purity commercially pure titanium and titanium alloy materials, with industry-leading precision TIG/plasma automatic welding technology, cold forming and vacuum annealing treatment.

1.Industry-Leading Welding Quality ：

Adopt full-automatic tungsten inert gas (TIG) / plasma welding process, 100% non-destructive testing for weld seams. The weld formation is uniform and dense, no porosity, crack or inclusion, the weld strength reaches more than 95% of the base metal, no welding embrittlement risk, and supports on-site secondary welding processing.

2.Superior Corrosion Resistance ：

Excellent corrosion resistance in seawater, chloride ion environment, strong acid and alkali, oxidizing media and other harsh conditions, service life is 3-5 times longer than stainless steel and copper alloy, greatly reducing equipment maintenance and replacement costs. Grade 7 titanium coil with palladium addition provides extra resistance to crevice corrosion in extreme reducing acid environments.

3.Ultra-High Strength-to-Weight Ratio ：

The density of titanium is only 60% of steel, but with comparable strength to high-strength steel. The lightweight design reduces equipment load, simplifies on-site installation, and lowers transportation and construction costs.

4.Wide Temperature Adaptability ：

Stable performance in an ultra-wide working temperature range from -269℃ (cryogenic environment) to 500℃. Maintains excellent toughness at ultra-low temperatures, and stable mechanical strength at high temperatures, fully adapting to extreme working conditions.

5.High Purity & Biocompatibility ：

Non-toxic, no harmful substance precipitation, compliant with food-grade and pharmaceutical-grade sanitary standards. The smooth inner wall reduces fluid resistance and medium residue, suitable for sterile fluid transportation in pharmaceutical, biological engineering and food & beverage industries.

6.Continuous Long Length Design :

Standard continuous length up to 100m, maximum customizable length up to 600m without intermediate joints. Greatly reduces the number of pipeline connections, lowers leakage risk, reduces on-site welding workload, and shortens project construction cycle.

We implement a full-process traceable quality management system, from raw material incoming inspection to finished product delivery, every process is strictly controlled :

- Raw Material Inspection : Titanium ingots comply with ASTM B348 standard, full-spectrum chemical composition analysis, mechanical property testing, 100% traceable raw material source.

- Precision Forming : Cold rolling / cold drawing forming process, ensure uniform wall thickness, high dimensional accuracy, meet international standard tolerance requirements.

- Automatic Welding : Closed inert gas protection automatic welding, avoid titanium oxidation during welding, real-time welding parameter monitoring, ensure stable weld quality.

- Heat Treatment : Vacuum annealing treatment, eliminate internal stress of the coil, optimize the metallographic structure, ensure the plasticity and toughness of the tubing.

- Surface Treatment : Optional pickling and passivation (AP), bright annealing (BA), mechanical polishing (MP), electrolytic polishing (EP) to meet different working condition requirements.

- Finished Product Testing : 100% non-destructive testing (eddy current testing + ultrasonic testing), hydrostatic / pneumatic pressure test, metallographic analysis, tensile test, flattening and flaring test, ensure every coil meets the standard.

Q: What's the difference between welded titanium coil and seamless titanium coil?

A: Welded titanium coil has more uniform wall thickness, longer continuous length (up to 600m), lower production cost and shorter delivery time, with weld strength reaching over 95% of the base metal, suitable for most corrosion-resistant, heat exchange and general fluid transportation scenarios. Seamless titanium coil has better pressure resistance, suitable for ultra-high pressure and extreme high-temperature working conditions, with higher cost and longer delivery time. We can recommend the most suitable type according to your working conditions.

Q: What grades of titanium are available for your welding coils?

A: Our standard stock grades are Grade 1 (TA1) and Grade 2 (TA2), the most widely used general-purpose grades. We also provide Grade 5 (Ti-6Al-4V), Grade 7 (Ti-0.2Pd), Grade 9 (Ti-3Al-2.5V) and other titanium alloy grades, and can customize special grades according to your project requirements.

Q: What standards do your titanium welding coils comply with?

A: Our products are manufactured in strict accordance with ASTM B338, ASTM B861, ASME SB-338 standards, and can also comply with EN ISO 12708, JIS H4631, DIN 17861, GB/T 3625 and other international and national standards according to your requirements.

Q: What's your minimum order quantity (MOQ) for titanium welding coils?

A: For standard in-stock specifications, we support low MOQ of 1 meter for sample testing. For custom orders, the MOQ is flexible, we can accept small batch custom orders according to your specific requirements, please contact our sales team for details.

Q: Can you provide custom size and processing for titanium welding coils?

A: Yes, we have a professional customization team. We can customize the outer diameter, wall thickness, coil length, roll diameter according to your drawings or parameters, and provide secondary processing services such as bending, flaring, flange welding, and fitting assembly.

Q: How do you guarantee the welding quality of the titanium coil?

A: We adopt full-automatic closed inert gas protection welding process to avoid titanium oxidation during welding, with real-time welding parameter monitoring. Every coil undergoes 100% eddy current testing (ET) and ultrasonic testing (UT) for weld seams, as well as hydrostatic pressure test, metallographic analysis and mechanical property testing, to ensure that the weld quality fully meets the standard requirements.

Q: Do you provide Mill Test Certificate (MTC) with the products?

A: Yes, we provide a complete Mill Test Certificate (EN 10204 3.1 standard) with every shipment, which includes chemical composition, mechanical properties, heat treatment batch number, non-destructive testing results and other full quality data. We can also provide EN 10204 3.2 third-party certified MTC according to your requirements.

Q: Can you provide samples before bulk order?

A: Yes, we provide free sample pieces (within 1 meter) for material and quality testing, you only need to bear the international shipping cost. For longer sample coils, we can provide them at a favorable sample price.

Q: What's the maximum continuous length of your titanium welding coil?

A: Our standard maximum continuous length is 600m without intermediate joints, which can greatly reduce the number of on-site welding joints and leakage risk. We can also customize shorter lengths according to your installation requirements.

Q: What surface treatments are available for titanium welding coils?

A: Our standard surface treatment is pickling and passivation (AP), which provides the best corrosion resistance. We also provide bright annealing (BA), mechanical polishing (MP), electrolytic polishing (EP) for sanitary grade applications, and can customize special surface treatments according to your needs
