The difference between the stainless steel elbow and the carbon steel elbow is mainly due to the difference in material. The chemical composition of the elbow will keep the surface of the elbow from rusting for a long time and will not be corroded.
     In a piping system, an elbow is a pipe that changes the direction of the pipe. According to the angle, 90 ° 180 ° two are more commonly used.
     According to the production process, it can be divided into: welding elbow, stamping elbow, hot bending elbow, push elbow, casting elbow, forged elbow, clip elbow, etc.
     Characteristics of stainless steel: Strength and toughness index are better among various steels. Its outstanding advantage is corrosion resistance. Stainless steel must be used in corrosive environments such as chemical papermaking.

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. 22.5o elbows are also available.

The end of this product 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.

These 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 of them 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.

Note: Long radius elbow refers to its radius of curvature is equal to 1.5 times the diameter of the pipe, R＝1.5D

Note: Short radius elbow refers to its radius of curvature is equal to 1 times the diameter of the pipe, R＝1D

Packing Information
Stainless steel elbows are packed and labeled according to the regulations and customer's requests. Great care is taken to avoid any damage which might be caused during storage or international transportation. In addition, clear labels are tagged on the outside of the packages for easy identification of the product I. D. and quality information.
