Titanium welded pipes are made of titanium materials and are widely used in petrochemical, marine engineering, aerospace, medical equipment, and other fields. The manufacture of titanium welded pipes needs to comply with strict production processes and implementation standards. The following will introduce the production process and implementation standards of titanium welded pipes.
The Production Process of titanium welded pipes
1. Material preparation
Titanium material is the main material of titanium welded pipes, and its quality has a very large impact on the quality of titanium welded pipes. Titanium materials need to undergo chemical composition analysis, hydrogen capture analysis, ultrasonic detection, discharge spectroscopy, and other tests to ensure that they meet product requirements.
2. Preparation of tube blanks
Titanium materials are processed into tube blanks that meet the requirements by forging, rolling, extrusion, and other methods.
3. Processing and molding
The prepared tube blanks are molded, including cutting, grooving, drilling, welding, and other processes, to make them standard titanium welded pipes.
4. Sandblasting and cleaning
Sandblast the titanium welded pipe to remove impurities such as surface oxide layer and stains, and then perform multiple cleaning to ensure that the surface of the pipe is smooth and pollution-free.
5. Longitudinal seamless welding
The pipe is continuously pushed forward at a certain interval, and high-frequency heating and pressure welding are performed at the same time to automatically connect it into a long pipe to complete the longitudinal seamless welding.
6. Finished product processing
The welded long pipe is trimmed, straightened, flaw detected, heat treated and other processing to meet the product standards.
7. Inspection
The processed titanium welded pipe is inspected, mainly including appearance inspection, chemical composition analysis, mechanical properties testing, non-destructive testing and other tests.
Implementation standards of titanium welded pipes
1. American standards
The American standard stipulates the chemical composition, mechanical properties and non-destructive testing of titanium welded pipes, and gives the qualified standards for the weldability, machinability, internal and external surface quality of the pipe.
2. European standards
European standards have detailed provisions for the manufacturing, materials, processing, quality control and other aspects of titanium welded pipes, attach importance to environmental protection and employee safety, and set high standards for the quality requirements of titanium welded pipes.
3. International standards
International standards mainly include ASTM, ASME, AMS and other organizations, which stipulate the quality standards of titanium welded pipes to ensure that they meet the relevant use requirements and ensure the stable and reliable quality of products.
In short, the production process and implementation standards of titanium welded pipes are the basis for ensuring their stable and reliable quality. We should strictly follow the standard operation during the production process to ensure that the product quality meets the requirements and provide better titanium welded pipes for applications in various fields.
