1. Description

    The bevel end of stainless steel pipe fittings is an important processing step in pipeline connection, which involves cutting the end of the pipe at a specific angle to facilitate welding. The following are some detailed descriptions of the bevel end of stainless steel pipe fittings:

(1) Bevel angle: The bevel of stainless steel pipe usually has a standard angle of about 30° or 37.5°. To make sure that the full thickness of the pipe can be covered during welding, thereby ensuring the mechanical continuity of the connection.

(2) Groove Type: Common groove types include single V-groove, double V-groove (also called X-groove), U-groove and J-groove.

(3) Groove face width: The root face of the groove usually has a width of about 1.6mm, which helps control the weld thickness during welding stainless steel fittings.

(4) Beveling Processing Methods: Beveling can be processed by hand grinding, flame cutting or plasma cutting, lathe processing or mechanical beveling machine.

(5) Importance of groove: Proper groove can improve the quality of welds and ensure a larger welding surface area, making the weld stronger and more reliable.

(6) Aesthetics and safety: In addition to weld preparation, beveling can also be used to remove burrs from cut ends.

2. Difference of manual grinding and mechanical beveling machines

    Choosing the appropriate method depends on specific production needs, cost budget and quality requirements.

(1) Manual grinding

- Flexible to operate, suitable for single-piece production or pipe fittings with complex structures.

- Can conform to irregular or difficult to machine areas.

- Not suitable for thicker pipes or welding processes requiring more stringent requirements.

(2) Mechanical beveling machines

- Mass production

- Can provide consistent and repeatable groove quality with high precision.
