The connection steps of stainless steel pipe fittings for crimping connection of small pipe diameter and large pipe diameter are the same, but the methods are different. First, let's take a look at the steps and methods of clamping connection of stainless steel pipe fittings with pipe diameter of DN50:

1. Pipe break: cut the pipe according to the required length. Do not use too much force to prevent the pipe from being out of round.

2. Burr removal: After the pipe is cut off, the burr shall be removed to avoid cutting the seal ring.

3. Marking: in order to make the steel pipe fully inserted into the fitting socket, the insertion length must be marked and marked at the pipe end.

4. Assembly: The sealing ring shall be correctly installed in the U-shaped groove of the pipe fitting, and the pipe shall be inserted into the socket of the stainless steel pipe fitting, waiting for crimping.

5. Crimping: During crimping, the convex part of the pipe fitting is placed in the concave groove of the mold, and the jaw is perpendicular to the pipe axis.

6. Inspection: After crimping, use a special gauge to check the crimping size.
