Titanium welded pipe is a kind of pipe made of titanium material, which is 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 production process and implementation standards of titanium welded pipes will be introduced below.
Production process of titanium welded pipe
1. Material preparation
Titanium material is the main material of titanium welded pipe, and its quality has a great influence on the quality of titanium welded pipe. Titanium materials need to undergo multiple tests such as chemical composition analysis, hydrogen capture analysis, ultrasonic testing, and discharge spectroscopy to ensure that they meet product requirements.
2. Prepare tube blank
Through forging, rolling, extrusion and other methods, the titanium material is processed into a tube blank that meets the requirements.
3. Processing and forming
The finished tube blank is processed, including blanking, grooving, drilling, welding and other processes, to make it a standard titanium welded tube.
4. Sand blasting and cleaning
Sand blast the titanium welded pipe to remove impurities such as surface oxide layer and stains, and then perform multiple cleanings to ensure that the surface of the pipe is clean and pollution-free.
5. Longitudinal seamless welding
The tubes are continuously advanced according to a certain distance, and high-frequency heating and pressure welding are carried out at the same time, so that they are automatically connected to the long tubes to complete the longitudinal seamless welding.
6. Finished products
Trimming, straightening, flaw detection, heat treatment and other processing are carried out on the welded long pipe to make it meet the product standard.
7. Inspection
The inspection of the processed titanium welded pipe mainly includes appearance inspection, chemical composition analysis, mechanical performance inspection, non-destructive flaw detection and many other inspections.
Executive standard of titanium welded pipe
1. American Standard
The American standard stipulates the chemical composition, mechanical properties and non-destructive testing requirements of titanium welded pipes, and gives the weldability, machinability, internal and external surface quality and other qualified standards of the pipe.
2. European standard
European standards have made detailed regulations on the manufacture, materials, processing, and quality control of titanium welded pipes, paying attention to environmental protection and employee safety, and set the quality requirements of titanium welded pipes as high standards.
3. International standard
International standards mainly include ASTM, ASME, AMS and other organizations. These organizations stipulate the quality standards of titanium welded pipes to ensure that they meet relevant use requirements and ensure stable and reliable product quality.
In short, the production process and implementation standards of titanium welded pipes are the basis to ensure its stable and reliable quality. We should strictly follow the standard operation in the production process to ensure that the quality of products meets the requirements and provide better titanium welded pipes for applications in various fields.
