Detailed explanation of precision machining process flow for titanium flange strip connection

Titanium flange connecting pipe is a key connecting accessory in chemical, chlor alkali, marine engineering, and heat exchange equipment, which combines flange sealing and pipeline diversion functions. Relying on the lightweight, high-strength, and acid alkali corrosion resistant characteristics of titanium material, this accessory can adapt to harsh working conditions such as high temperature, high pressure, and strong corrosion. Its processing accuracy, welding quality, and forming process directly determine the equipment's sealing and operational stability.

The titanium flange strip connection processing procedure is rigorous, and the entire process follows the national and American standard process standards. Firstly, raw material selection and cutting are carried out, selecting high-quality raw materials such as TA2 pure titanium and TC4 titanium alloy. The material composition is strictly screened to eliminate impurities and defects. The raw materials are precisely cut according to the drawing size to ensure the basic quality of the raw materials. Subsequently, forging and heat treatment were carried out to refine the internal grain size through high-temperature forging, eliminate internal stress in the billet, and improve the strength and toughness of the workpiece through annealing treatment, avoiding deformation and cracking during later use.

The core process is integrated precision machining, using CNC numerical control equipment to precision machine flange sealing surfaces, bolt holes, and inner and outer diameters of connecting pipes, strictly controlling dimensional tolerances and sealing surface smoothness, ensuring flange fitting accuracy and pipeline coaxiality. After completing the machining, seamless welding is carried out to form the flange. Special titanium welding technology is used to eliminate porosity and virtual welding problems, ensuring that the flange and connecting pipe are integrated and pressure stable.

Finally, after acid pickling and passivation, non-destructive testing, pressure testing, and dimensional re inspection, the surface oxide layer is removed, internal defects are checked, and the product's corrosion resistance and sealing meet the requirements of industrial high-pressure continuous operation.
