        High pressure elbow
        High pressure elbow
        • PRODUCT NAME:

          High pressure elbow

        • DESCRIPTION:
          High pressure elbow is a kind of pipe used for turning different angles in the bend of high pressure pipeline...



        Introduction of 1. high pressure elbow:

        High pressure elbow is a kind of pipe used for turning different angles in the bend of high pressure pipeline. In the high pressure piping system used in all pipe fittings, the proportion is large, about 80%. Generally, the wall thickness of high pressure elbow is thicker than that of common elbow, or the strength of material is higher than that of ordinary elbow. A butt weld and socket welding and threaded connection in three ways. The material of high pressure elbow is usually made of high quality cast steel, carbon steel, stainless steel or alloy steel, which can make the high pressure elbow bear high pressure in all kinds of high pressure pipes and bear the corrosion of the fluid in the pipeline.

        Characteristics of 2. high pressure elbow:

        High pressure elbow not only has good compression ability, but also needs other excellent characteristics in different piping systems. For example, in the concrete pipeline, the high pressure elbow in the slurry pipeline not only can withstand higher pipeline pressure, but also has good wear resistance. In the chemical raw material transportation pipeline system, high pressure elbow, in addition to withstand higher pipeline pressure, but also has a good corrosion resistance and acid and alkali resistance.

        3. scope of application:

        High pressure elbow resistant to high pressure is generally applicable to petroleum, natural gas, aerospace, shipping, chemical, hydropower, fire, building and boiler industry pipeline series. High pressure elbow is suitable for pipeline systems in petroleum, natural gas, chemical industry, hydropower, building and boiler industry. Without pipe blank as raw material, the cost of pipe making equipment and mould can be saved, and the national standard elbow with thinner diameter and thinner wall thickness can be obtained. Due to the above two reasons, the manufacturing cycle can be shortened and the production cost will be greatly reduced. Because it doesn't need any special equipment, it is especially suitable for machining large national standard elbow. The blank is flat or developable surface, so the blanking is simple, the accuracy is easy to guarantee, and the assembly and welding are convenient.

        Manufacture technology of 4. high pressure elbow

        Production technology of high pressure elbow welding a first cross section is polygonal multiple ring shell or both ends closed multiple fan-shaped shells, full of internal pressure medium, subjected to internal pressure, internal pressure under the action of the cross-section of the polygon gradually turned round, back into a circular ring shell. According to the requirements, a circular ring shell can be cut into 4 90 elbow or 6 60 high pressure elbow or other specifications of the high pressure elbow, the process is suitable for manufacturing high pressure elbow, diameter and stamping elbow inner diameter ratio is greater than 1. 5 any size large elbow is the ideal way to manufacture large national standard elbow.
