Stainless Steel Elbow
Stainless steel elbow is usually installed between two lengths of stainless steel pipe(or tubing) to allow a change of direction, usually a 180º, 90º, or 45º angle. 22.5ºstainless steel elbows are also available. The end of stainless steel elbow may be machined for butt welding, threaded (usually female) or socket. When the ends differ in size, it is known as a reducing (or a reducer) elbow. Stainless steel elbows are categorized by design. The radius of a long-radius (LR) elbow is 1.5 times the pipe diameter. In a short-radius (SR) elbow, the radius equals the pipe diameter. Ninety-, 60- and 45-degree elbows are also available. Most stainless steel elbows are available in short- or long-radius versions. Short SS elbow, widely available, are typically used in pressurized systems. Long stainless steel elbows are used in low-pressure gravity-fed systems. Jiangsu Sheye Metal is a professional manufacturer specialized in manufacturing stainless steel elbow. According to different production process, stainless steel elbows can be divided into two types: seamless stainless steel elbows and welded stainless steel elbow. There are main four types elbows like: 45º Stainless Steel Elbow,90º SR Stainless Steel Elbow(Short Radius),90º LR Stainless Steel Elbow(Length Radius),180º Stainless Steel Elbow. The outside diameter of stainless steel elbows we produce ranges from 4.0 mm to 1219mm. The wall thickness is 0.5mm to 40mm. For metal, we are serious.
