Titanium welded pipe is a special metal welding material. Due to its excellent corrosion resistance and high-temperature strength, it is widely used in the chemical industry, medicine, shipbuilding, aerospace, and other fields. The product specifications and standards of 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 its basic product specifications. According to different application requirements, titanium welded pipes of different specifications can be produced. The common outer diameter range is 0.5mm-200mm, and the wall thickness range is 0.1mm-10mm.
Length: The length of the titanium welded pipe can be customized according to customer needs. Common lengths are 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.
Heat treatment: To improve the tensile strength and corrosion resistance of titanium welded pipes, heat treatment can be performed. Common heating treatment methods include solution treatment, aging treatment, etc.
2. Product standards
Global standards: The main global standards for titanium welded pipes 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, including requirements for titanium and titanium alloy seamless and welded pipes.
Domestic standards: Domestic standards for titanium welded pipes mainly include GB/T (national standards) and JB (aerospace industry standards). GB/T 3625 is China’s standard for titanium and titanium alloy seamless pipes, and GB/T 3624 is China’s standard for titanium and titanium alloy welded pipes. 3 Inch Titanium Pipe / Gr1 Pure Titanium Pipe / Grade 3 Pure Titanium Pipe
Corporate standards: Many titanium welded pipe manufacturers will develop their own corporate standards to meet specific customer needs or product characteristics. Enterprise standards usually refer to global standards or domestic standards, and make some supplements or improvements based on them with special requirements.
In addition to the above product specifications and standards, there are some other related specifications and standards that need attention.
Compliant pipe fittings: In the application of titanium welded pipes, some conforming pipe fittings are often needed, such as elbows, tees, reducers, etc. The specifications and standards of these pipe fittings need to match those of titanium welded pipes to ensure the reliability and sealing of their connections.
Testing standards: Quality testing of titanium welded pipes is an important step in ensuring product quality. Common testing standards include chemical composition analysis, mechanical property testing, non-destructive testing (ultrasonic, radiation, penetration, etc.), etc.
To sum up, the product specifications and standards of titanium welded pipes are relatively rich, mainly including specifications in terms of outer diameter, wall thickness, length, surface treatment, heat treatment, etc., as well as various standard requirements such as global standards, domestic standards, and corporate standards. These specifications and standards can ensure the product quality and performance of titanium welded pipes and meet the needs of different industries and fields.
