Analytical high pressure elbow high-pressure pipe production process

Elbow production process is FD-LOK socket weld fittings a first polygonal cross-section or a polygonal ring shell closed at both ends of the multi-row fan shell, inside elbow washed over the pressure medium within the pressure applied, including action under pressure from the polygonal cross-section gradually turned round, eventually becoming a circular ring shell, this process ideally suited to the high-pressure method and stamping elbow elbow in diameter than the inner diameter larger than any standard 1.5 large elbow, is to create a large national standard elbow manufacturing. Elbow high pressure pipeline system applicable to oil, gas, chemicals, utilities, construction and boiler industry. Without tube for raw materials, equipment and metric pipe fittings can save tooling costs and arbitrarily large diameter and wall thickness can be obtained relatively thin GB elbow. Elbow can shorten the manufacturing cycle, the production cost is greatly reduced. Does not require any special equipment, it is particularly suitable for on-site processing of large GB elbow. Blank or developable surface is flat, so simple cutting, easy to ensure accuracy, easy assembly and welding. While high pressure elbow high pressure generally applicable to oil, gas, aerospace, shipbuilding, chemicals, utilities, fire protection, construction and other industries boiler piping series.
