Elliptical pipe

Elliptical tubes are generally extruded into the shape of duck eggs based on circular tubes. Elliptical tubes are divided into regular ellipses and flat ellipses. Regular ellipses refer to duck egg shapes with symmetrical curvature, while flat ellipses refer to two long faces parallel to straight lines and two short faces forming a circular arc shape. It is mainly widely used in industrial transportation pipelines and mechanical structural components such as petroleum, chemical, diagnosis and treatment, food, light industry, mechanical instruments, etc.

Operation methods for reels and reels

1. The diameter of the rolled round barrel is small (i.e. the curvature radius is small) and the wall thickness is small. Before using a four roll plate rolling machine to roll, a circular arc template should be made, and the pre bending curvature should be checked with the template while pre bending. The bending should be slightly more, but not too much, and this step should be too thin.
2. If the pre bending amount is too large or insufficient, after welding is completed, a circular arc inclined iron can be used on the plate rolling machine to pad and calibrate the weld seam at the pout or concave position to roll out a qualified cylinder.
3. When the plate rolling machine rolls the plate, from the geometric position of the plate head and plate tail on the machine, the plate head and plate tail will not be a circle. Taking the symmetrical three rollers as an example, during the rolling process on the side of the plate head at the center of the upper roller, the shape of the plate changes from a straight line (short) - arc to an arc - arc. Although the position of the three rollers does not change during this process, the deformation of the steel plate changes.
