90° Long Weld Elbow is a kind of pipe fittings used for connection and bending in piping system. It is usually made of cast iron, carbon steel, stainless steel and other materials, with excellent properties such as corrosion resistance, high strength and long service life. Below, we will introduce 90° long welded elbow in detail from the material, production process, application characteristics.
First, the material
Cast iron: cast iron is a common material used for 90 ° long welding elbow, which has high strength, corrosion resistance, wear resistance and other characteristics. Cast iron can be divided into gray cast iron, ductile iron and so on according to its graphite organization.
Steel: steel is also one of the common materials used in 90° long weld elbow, which has good strength and wear resistance, and is widely used in the chemical industry, petroleum, natural gas and other fields. Commonly used steel are carbon steel, alloy steel, stainless steel and so on.
Stainless steel: stainless steel is a corrosion-resistant material with excellent corrosion resistance and strength, commonly used in piping systems in high-temperature, high-pressure environment.
Alloy Materials: Alloy materials refer to materials made of steel with other elements added, such as chromium, molybdenum, nickel, and so on. Alloy materials have high temperature resistance, corrosion resistance and other characteristics, often used in chemical, petroleum and other fields of piping systems.
Second, the production process
The process of producing 90° long welded elbow includes material preparation, casting, welding and other links.
Material preparation: in the production process, you need to first prepare the required materials, such as cast iron, steel, stainless steel, alloy materials.
Casting: casting is the main process for producing 90° long weld elbow, which can be manufactured by sand casting, plaster model casting, pneumatic casting and other methods, of which sand casting is the most common.
Welding: In the production process of 90° long welded elbow, if you need to connect the pipeline, you also need to carry out welding processing. Welding process includes manual arc welding, argon arc welding, plasma welding and so on.
Third, the application characteristics
90° long welded elbow is usually used in oil and gas pipelines, chemical pipelines, ship bulkheads, construction and other fields;
90° long welded elbow has a certain pressure-bearing capacity and corrosion resistance, suitable for pipeline connection and bending in a variety of environments;
The connection methods of 90° long welded elbow include welding connection, threaded connection, etc., which are characterized by tight connection and high strength;
The 90° long welded elbow supports customization, and can be made in accordance with customer requirements for different diameters, bending angles, materials and other products.
In short, as an important pipe fitting, 90° long welded elbow plays an important role in the field of chemical industry, petroleum, natural gas and other fields. When in use, you need to choose the right material and connection method according to the actual situation to ensure the safe and stable operation of the pipeline system.
