What are the specifications and standards for titanium welded pipe products?


Titanium welded pipe is a special metal welding material that is widely used in fields such as chemical, pharmaceutical, shipbuilding, aerospace, etc. due to its excellent corrosion resistance and high-temperature strength. The product specifications and standards for titanium welded pipes mainly include the following aspects.

1、 Product specifications

Outer diameter and wall thickness: The outer diameter and wall thickness of titanium welded pipes are the basic product specifications, and different specifications of titanium welded pipes can be produced according to different application requirements. The common outer diameter range is 0.5mm-200mm, and the wall thickness range is 0.1mm-10mm.

Length: The length of titanium welded pipes can be customized according to customer needs, with common lengths of 6m, 12m, etc. At the same time, it can also be processed according to special needs, such as cutting into short sections, bending into arcs, etc.

Surface treatment: The surface of titanium welded pipes can be treated differently to meet different usage scenarios. Common surface treatments include polishing, sandblasting, pickling, etc.

Heating treatment: In order to improve the tensile strength and corrosion resistance of titanium welded pipes, heating treatment can be carried out. Common heating treatment methods include solid solution treatment, aging treatment, etc.

2、 Product standards

Global Standards: The global standards for titanium welded pipes mainly include ASTM (American Society for Testing and Materials), ASME (American Society of Mechanical Engineers), ISO (Global Organization for Standardization), etc. ASTM B338 is a common global standard for titanium welded pipes, which includes requirements for seamless and welded pipes made of titanium and titanium alloys.

Domestic standards: The domestic standards for titanium welded pipes mainly include GB/T (national standard) and JB (aerospace industry standard). GB/T 3625 is the standard for seamless titanium and titanium alloy pipes in China, and GB/T 3624 is the standard for welded titanium and titanium alloy pipes in China.

Enterprise standards: Many titanium welded pipe production companies will develop their own enterprise standards to meet specific customer needs or product characteristics. Enterprise standards usually refer to global or domestic standards and supplement or improve them with special requirements.

In addition to the above product specifications and standards, there are also some other related specifications and standards that need to be paid attention to.

Compliant fittings: In the application of titanium welded pipes, it is often necessary to use some compliant fittings, such as elbows, tees, reducers, etc. These specifications and standards that comply with the fittings need to be matched with the specifications and standards of titanium welded pipes to ensure the reliability and sealing of their connections.

Testing standard: The quality inspection of titanium welded pipes is an important link to ensure product quality. Common testing standards include chemical composition analysis, mechanical performance testing, non-destructive testing (such as ultrasound, radiation, and penetration), etc.

In summary, the product specifications and standards for titanium welded pipes are relatively rich, mainly including specifications for outer diameter, wall thickness, length, surface treatment, heating treatment, as well as various standard requirements such as global standards, domestic standards, and enterprise standards. These specifications and standards can ensure the product quality and performance of titanium welded pipes, meeting the needs of different industries and fields.
