  • Time of issue:2020/12/02

(Summary description)Under normal circumstances, the elbows sold by elbow sellers can be divided into 45°, 90°, 180°, etc. according to the angle. These three elbows are more commonly used, and according to The engineering needs also include other abnormal angle elbows such as 60°. The materials for producing elbows mainly include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics.

弯头销售商在生产弯头的技术要求有哪些?

Under normal circumstances, the elbows sold by elbow sellers can be divided into 45°, 90°, 180°, etc. according to the angle. These three elbows are more commonly used, and according to The engineering needs also include other abnormal angle elbows such as 60°.

In the pipeline system, the elbow is a pipe fitting that changes the direction of the pipeline. At present, it has been widely used and has received many praises. With the rapid development of various industries, the pipeline system has also continued to improve, which to a large extent requires In the process of elbow production, elbow sellers must produce according to certain standards and technical requirements. What are the technical requirements of elbow sellers in the production of elbows?

Since most of the pipe fittings are used for welding, in order to improve the welding quality, the elbow sellers turn the ends into bevels, leaving a certain angle and with a certain edge. This requirement is also relatively strict, the thickness of the edge, the angle The number and range of deviation are specified. The surface quality and mechanical properties are basically the same as the tube. In addition, in order to make their products easy to weld, elbow sellers choose the same steel grade as the pipe to be connected.

When producing all pipe fittings, elbow sellers must surface-treat them, spray off the iron oxide scale on the inner and outer surfaces by shot peening, and then apply anti-corrosion paint. This is also the need of the elbow sellers for export, and the elbow is also in the country to facilitate transportation to prevent rust and oxidation, and must do this work.

After the elbow sellers have finished producing the elbows, they also have requirements for the packaging of the elbows. For small pipe fittings, if they are exported, they need to be made in wooden boxes, about 1 cubic meter. It is stipulated that the number of elbows in this box should not exceed about one. Tons, the standard allows sets, that is, large sets are small, but the total weight generally cannot exceed 1 ton. For large items, they must be individually packaged, and those like 24" must be individually packaged. The other is the packaging mark, which should indicate the size, steel number, batch number, manufacturer's trademark, etc.
