Production Of Bell-mouth Reducers In Stainless Steel Seam Pipe Fittings

The method of making the trumpet size head in Stainless Steel Weld Fitting is as follows:

Calculate the arc length according to the upper and lower diameters, calculate the fan width according to the height, use a rope and a ruler to draw a line on the material, and cut the material along the line.

Method/Steps: First, distinguish the front and back of the cloth. In general, the front is more compact, flat and smooth, and more shiny than the back. The pattern on the back is not obvious and the luster is poor. Then, when cutting the cloth, the cloth is folded in a positive way. In the picture, the cloth grain line is parallel to the cloth edge, and the cloth fold line is parallel to the cloth edge. Next, press the iron on the pattern, and then pick up some stones by the river and wash them.

Then, because the cardboard has been sewn, along the edge, the scissors are tilted outward a little, cut a circle, and when turning, use the scissors a little in front, cut a little flatter, cut a little deeper with the scissors, and cut a little longer with each scissors. Pay attention to the use of tools such as scissors.

Bell mouths mainly appear in the water supply and drainage profession, such as the water suction bell mouth. The diameter at the entrance should be larger than the pipe diameter. Figuratively speaking, the shape of the bell mouth is similar to a big and small head, and the end with a smaller diameter is the same as the pipe diameter.
