Titanium welded pipe is a type of pipe made of titanium material, widely used in fields such as petrochemicals, marine engineering, aerospace, etc. The manufacturing of titanium welded pipes requires strict production processes and execution standards. The following will introduce the production process and execution standards of titanium welded pipes.

1、 Production process of titanium welded pipe

1. Material preparation

Titanium material is the main material for titanium welded pipes, and its quality has a significant impact on the quality of titanium welded pipes. Titanium materials require multiple tests such as chemical composition analysis, hydrogen capture analysis, ultrasonic testing, and discharge spectroscopy to ensure they meet product requirements.

2. Prepare pipe blanks

By forging, rolling, extrusion and other methods, titanium materials are processed into tube blanks that meet the requirements.

3. Processing and molding

The finished pipe blank is subjected to forming processing, including cutting, slotting, drilling, welding, etc., to make it a standard titanium welded pipe.

4. Sandblasting and cleaning

Sandblasting the titanium welded pipe to remove impurities such as surface oxide layer and stains, and then performing multiple cleaning steps to ensure a smooth and pollution-free surface of the pipe.

5. Longitudinal seamless welding

Continuously advance the pipes at a certain distance, while performing high-frequency heating and pressure welding, to automatically connect them into long pipes and complete longitudinal seamless welding.

6. Processing finished products

Repair, straighten, perform non-destructive testing, heat treatment, and other processing on welded long pipes to meet product standards.

7. Inspection

The inspection of processed titanium welded pipes mainly includes multiple tests such as visual inspection, chemical composition analysis, mechanical performance testing, non-destructive testing, etc.

2、 Execution standards for titanium welded pipes

1. American standards

The American standard specifies the chemical composition, mechanical properties, and non-destructive testing requirements for titanium welded pipes, and provides qualified standards for the weldability, machinability, and internal and external surface quality of the pipes.

2. European standards

The European standards provide detailed regulations on the manufacturing, materials, processing, and quality control of titanium welded pipes, emphasizing environmental protection and employee safety, and setting high quality requirements for titanium welded pipes.

3. International standards

International standards mainly include multiple organizations such as ASTM, ASME, AMS, etc. These organizations establish quality standards for titanium welded pipes to ensure that they meet relevant usage requirements and ensure stable and reliable product quality.

In short, the production process and execution standards of titanium welded pipes are the foundation for ensuring their stable and reliable quality. We should strictly follow the standard operation in the production process to ensure that the product quality meets the requirements and provide better titanium welded pipes for applications in various fields.
