Because our products are of good quality and excellent price, they have won unanimous praise from people inside and outside the industry. The 45°welded elbow and welded elbow are our company's main products. But also we are one of the most professional supplier in our country.Therefore, we have a lot of welding elbow for sale.
In piping systems, elbows are pipe fittings that change the direction of piping. According to the angle, there are three most commonly used types: 45° welded elbow and 90°180°. And other abnormal angle elbows such as 60°, are also included according to the engineering requirements.
Elbows are made of cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, nonferrous metals and plastics. The connection methods with pipes include: direct welding (the most common method) flange connection, hot melt connection, electric melt connection, threaded connection, socket connection.
According to the production process, it can be divided into welded elbow, stamped elbow, push elbow, cast elbow. Other names: 90 degree bend, right angle bend, love and bend;
According to the manufacturing method, it can be divided into pushing, pressing, forging, casting;
According to manufacturing standards, it can be divided into national standard, electric standard, ship standard, chemical standard, water standard, American standard, German standard, Japanese standard, Russian standard;
According to its radius of curvature, it can be divided into long radius elbow and short radius elbow. Long radius elbow refers to the outer diameter of the pipe whose radius of curvature is equal to 1.5 times, i.e. r = 1.5d; Short radius elbow means that its radius of curvature is equal to the outer diameter of the pipe, i.e. r = 1.0d. (d is the diameter of the elbow and r is the radius of curvature).
According to the pressure grade, there are about 17 types, which are the same as the pipe standards in the United States, including: sch5s, sch10s, sch10, sch20, sch30, sch40s, std, sch40, sch60, sch80s, XS; sch80、sch100、sch120、sch140、sch160、XXS; Std and XS are the two most commonly used.
According to different shapes and uses, it can be divided into: groove elbow, sleeve elbow, double bearing elbow, flange elbow, reducer elbow, stay seat elbow, inner and outer tooth elbow, stamping elbow, push elbow, socket elbow, welded elbow, inner wire elbow.
Welded elbows are also commonly used in our pipelines. This welding means the welding method required on the ports. Other types of elbows include socket welding elbows, threaded elbows, etc. Welded elbows are the most commonly used elbows. His general technical parameters include radius of curvature, pressure grade, caliber, size, material requirements, degree.
