Marine extrusion elbow and butt welding elbow

Extrusion elbow and butt welding elbow are commonly used marine elbow manufacturing process. The advantages of the two processes are different.

Stainless steel 304 butt weld 90 degee elbows

Extrusion elbow use special elbow forming machine, the tube billet into the mold, the upper and lower die after the mold, under the push rod, the tube billet along the inner and outer mold reserved gap movement and complete the forming process. The elbow made by the cold extrusion process of internal and external die is beautiful in appearance, uniform in wall thickness and small in size deviation. Therefore, the cold extrusion manufacturing process is applicable to the production and manufacturing of thin-wall stainless steel elbow. The wall thickness deviation of tube billet is also demanding.

A234 WPB large size 90 degree welded elbows

Butt welding elbow manufacture process of large diameter bend commonly used butt welding production process, the steel plate in the roll into the shape of a bend, then welding, after welding, and then shoot to the elbow, large diameter bend, generally USES the butt welding elbow, butt welding elbow pretty appearance than other manufacturing process, but DN800 elbow over other processes can’t manufacture, will adopt the butt welding elbow production process.
