Elbow in pipe system, elbow is the pipe that changes the direction of pipeline.
Use:A Pipe Fitting used in pipeline installation is used to connect two pipes with the same or different diameters to make the pipe turn at a certain angle and the nominal pressure is 1-1.6Mpa.
Application range: because of good comprehensive performance of the elbow, it is widely used in chemical, construction, water supply, drainage, oil, heavy industry, freezing, health, water heating, fire, electricity, space, shipbuilding and other basic projects.
Classification:
1, the material can be divided into cast iron, stainless steel, alloy steel, malleable iron, carbon steel, non-ferrous metals and plastics.
2, the production methods can be divided into push, press, forge, casting and so on.
3, according to its radius of curvature, it can be divided into long radius elbow and short radius elbow.
4, according to the pressure grade, there are about seventeen kinds, and the same as the American tube standards, such as Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; the most commonly used are the two kinds.
5, according to different shapes and uses can be divided into: groove elbow, card type elbow, double bearing elbow, flange elbow, different diameter elbow, bent head, bending head of internal and external teeth, stamping elbow, push bending head, socket elbow, butt elbow, inner wire elbow, etc.
Technical requirement:
It is required to control the radius of curvature. For example, if the radius is 1.5D, the radius of curvature must be within the required tolerance. Because most of these pipes are used for welding, in order to improve the welding quality, the end is all turned into a slope, a certain angle and a certain edge. This requirement is also strict, the edge is more thick, the angle is more and the deviation range is specified, and the geometric size is much more than the pipe. The surface quality and mechanical properties of elbow are basically the same as those of pipes. For welding convenience, the material of the steel connected to the pipe is the same.

·Dongbang Trix develops lightweight multi-material roof cover for Toyota SORA
According to foreign media reports, Tehoin Group's carbon fiber business core company - Toho Tenax Co., Ltd. developed a lightweight multi-material car for Toyota SORA, a Toyota fuel cell passenger car. Roof cover, made of carbon-fiber reinforced plastic (CFRP), aluminum and other lightweight engineering plastics. The roof cover allows for one large piece and is complex in shape for mass production.
Today, the global automotive industry is working to develop lightweight bodywork that improves vehicle fuel economy and ensures road stability. Since the superstructure of the passenger car is equipped with a high-pressure hydrogen tank, the role of this lightweight body component becomes very important.
Dongbang Trinex cooperates with GH Craft Ltd, a composite structure design and development department of Teijin Group, to combine the high-performance carbon fiber and mass production technology of the former with the molding technology of the latter. Material roof cover.
Continental Structural Plastics Holdings Corporation (CSP) was acquired by Teijin Group in January 2017, enhancing its global R&D capabilities.
