Product Name: Titanium grade 7 elbows Standard: ASME B16.9 Material: Gr1, Gr2, Gr7, Gr12 Unit Price: $10usd/pc-$200usd/pc Outer Diameter: 1/2"-48" Wall Thickness: Sch5s-Sch160s Technique: Seamless/Welded Functions and features: 1. Elbow is used to install between two sections of pipe or pipe allowing direction change. 2. Save space, reduce weight, with sealing function. 3. Economic reliability. Production methods of titanium elbow: 1.Hot push forming The hot pushing elbow forming process is a process of heating, expanding and bending the blank sleeved on the die under the push of the pushing machine by using a special elbow pushing machine, core die and heating device. 2.Stamping forming Stamping forming elbow is the first forming process used in batch production of seamless elbow. It has been replaced by hot pushing method or other forming processes in the production of common specifications of elbow. However, it is still used in some specifications of elbow due to special requirements for products with small production quantity, too thick or too thin wall thickness. The pipe blank equal to the outer diameter of the elbow is used for the stamping forming of the elbow, and the press is used to press directly in the die. 3.Medium plate welding Use the medium plate to make half of the elbow section with a press, and then weld the two sections together. This process is generally used for elbows above DN700.
