      Industry standards and main technical contents of titanium products

      Date:2022-03-30 09:39:46       Number of views:

      At present, there is no special titanium strip standard for titanium and titanium alloy welded pipes at home and abroad. Most titanium welded pipes are signed according to astmb338 and GB / t3625 standards. Almost all titanium strips for domestic welded pipes are imported from abroad. Because the forming process of welded pipes has the characteristics of increasing strength, especially yield strength value and slightly thinning thickness, At present, in the procurement of titanium strip for this purpose in China, all manufacturers basically put forward some special requirements for mechanical properties and thickness tolerance on the basis of astmb265. Based on the current situation, in order to facilitate the development of industrial products and coordinate the production, procurement and further forming of special titanium strip for welded pipe, this specification is mainly based on astmb265 standard and reasonably adjusted on its basis to ensure that all indexes of welded pipe meet the standard requirements.


      The main technical contents include: 

      1. Product classification: including the brand and status of materials, and the type and specification of products.

        2. Technical requirements: including chemical composition, allowable size deviation, mechanical properties, process properties and surface quality.

        3. Test methods .

        4. Inspection rules .

        5. Marks, packaging, etc. 6 Quality certificate.
