1. With flange refers to the pipe end to the medial or lateral convex and circular edge: in the circumference direction of the tube form a bulge or groove pipe fittings;
2. The stainless steel elbow variable wall thickness of pipe fittings, referring to along the length direction pipe wall thickness changes;
3. Turn straight into different curvature radius of bend, such as the elbow, bend, and so on;
4. Stainless steel elbow variable diameter pipe fittings, refers to one part of the tube or pipe diameter decreased; With edge and bottom sealing tube, increase the pipe's overall strength to pipe the inner or outer edge or the pipe end seal pipe fittings;
5. Change the pipe cross section, according to the requirements, the circular section into a square, oval, polygons, and so on.
In fact, stainless steel and stainless steel elbow is straight pipe processing, deformation.
