The Main Difference Between Elliptical Head And Butterfly Head
Date: | Read: 36
Pressure bearing capacity: Butterfly stainless steel weld caps can also enhance its pressure bearing capacity by increasing the cone angle.
Manufacturing process: The processing and manufacturing of ellipse weld on pipe caps steel is simpler than that of butterfly butt weld pipe cap, so the production cost of stainless buttweld caps is relatively low. Butterfly stainless steel buttweld caps needs to be processed and manufactured through complex processing technologies such as CNC cold drawing, so the production cost of steel buttweld caps is relatively high.
