1. Piping: Use a pipe cutter or grinding wheel cutting machine (the cutting blade should be specially used) to vertically cut the stainless steel pipe to the required length, trim the end burrs, and make a full circle.

2. Welding: The two left and right tapered flange flange pieces (with grooves, specially designed for embedding flange gaskets on both sides) are welded to the two piping ports that need to be connected using tungsten argon arc welding (TIG welding). .

3. Gasket: There are double-sided flange gaskets lined between the left and right flange pieces.

4. Fastening: Clamp the two flange pieces with a clamp, and then use a fastening screw (hexagon socket bolt) to clamp the flange or tighten the handle (one end of the external thread is connected to the internal thread of the handle, and one end is flexibly connected through a fixed rivet) .
