Super Duplex Pipe Fittings 90LR Elbow ASME B16.9 SMLS 1 1/2" SCH10S BW Pipe Fittings

Introduction of Elbow

Butt welding elbow is a steel hot pressed or forged elbow, which is connected directly by butt welding the elbow with the steel pipe.

(1) Butt welding elbows can be divided into long radius butt welding elbows and short radius butt welding elbows based on their curvature radius. The curvature radius of a long radius butt welded elbow is equal to 1.5 times the outer diameter of the pipe, i.e. R=1.5D. The curvature radius of a short radius butt welded elbow is equal to the outer diameter of the pipe, i.e. R=1D. In the formula, D is the diameter of the butt welded elbow, and R is the radius of curvature. Unless otherwise specified, a 1.5D elbow is generally used.

(2) If divided by pressure level, there are about seventeen types, which are the same as the American pipe standards, including: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, Sch100, Sch120, Sch140, Sch160, XXS, with the most commonly used being STD and XS.

(3) According to the angle of the elbow, there are 45 degree butt welding elbows, 90 degree butt welding elbows, 180 degree butt welding elbows, and other elbows with different angles.

(4) Materials include: carbon steel, alloy steel, and stainless steel.

Super Duplex stainless steel refers to a stainless steel with both austenite and ferrite metallographic structures. Super Duplex steel, also known as duplex steel. Generally, the steel composed of ferrite and austenite phase structure is called dual phase stainless steel, and the steel composed of ferrite and Martensite phase structure is called dual phase steel.

Super Duplex steel is obtained from low carbon steel or low alloy high-strength steel after critical zone heat treatment or controlled rolling. Typical yield strength of dual phase steel σ S is 310MPa, tensile strength σ B is 655MPa. Dual phase steel is used for manufacturing complex components formed by cold stamping and deep drawing, and can also be used as pipeline steel, chains, cold drawn steel wires, prestressed steel bars, etc.
