Titanium welded pipe is a kind of special metal welding material, which is widely used in chemical industry, medicine, ship, aerospace and other fields due to its excellent corrosion resistance and high temperature strength. The product specifications and standards of titanium welded pipe mainly include the following aspects.
I. Product specifications
Outer diameter and wall thickness: the outer diameter and wall thickness of titanium welded pipe is its basic product specifications, according to different application requirements, different specifications of titanium welded pipe can be produced. The common outer diameter range is 0.5mm-200mm, wall thickness range is 0.1mm-10mm.
Length: The length of titanium welded pipe can be customized according to customer's demand, the common length is 6m, 12m, etc.. Meanwhile, it can also be processed according to special requirements, such as cutting into short sections, bending into arcs, etc.
Surface treatment: The surface of titanium welded pipe can be treated in different ways 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 pipe, heating treatment can be carried out. Common heating treatments are solid solution treatment, aging treatment and so on.
Second, product standards
Global standards: the global standards for titanium welded pipe are mainly 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 pipe, including seamless and welded titanium and Titanium Alloy pipe requirements.
Domestic standards: Domestic standards for titanium welded pipes mainly include GB/T (national standard) and JB (aerospace industry standard), etc. GB/T 3625 is the Chinese standard for titanium and titanium alloy seamless pipes and GB/T 3624 is the Chinese standard for titanium and titanium alloy welded pipes.
Corporate standards: Many titanium welded pipe manufacturers will develop their own corporate standards to meet specific customer needs or product characteristics. The enterprise standards usually refer to the global standards or domestic standards, and on the basis of which some special requirements are supplemented or improved.
In addition to the above product specifications and standards, there are some other related specifications and standards that need attention.
Compliance fittings: In the application of titanium welded pipe, it is often necessary to use some compliance fittings, such as elbows, tees, reducers and so on. The specifications and standards of these fittings need to be matched with those of the titanium welded pipe to ensure the reliability and sealing of the connection.
Testing standards: The quality testing of titanium welded pipe is an important part of ensuring product quality. Common testing standards are chemical composition analysis, mechanical properties testing, non-destructive testing (ultrasonic, ray, penetration, etc.).
To summarize, the product specifications and standards of titanium welded pipe are relatively abundant, mainly including the specifications of outer diameter, wall thickness, length, surface treatment, heating treatment and other specifications, as well as the requirements of various standards such as global standards, domestic standards and enterprise standards. These specifications and standards can ensure the product quality and performance of titanium welded pipe to meet the needs of different industries and fields.
