We Can Supply Types of Butt Weld Fittings
| Elbow 45° and 90° – long radius is standard; Short Radius is also available. |
| Return bend 180° – Long Radius is standard; Short Radius is also available. |
| Reducer – Concentric and Eccentric. |
| Tee – Equal and Reducing. |
| Cap – Butt Weld |
| Stub End – Long and Short Pattern |
Stainless Steel Butt Weld Elbow
Stainless steel butt weld elbow can be divided into 45 degree ,90 degree, and 180 degree elbows according to the bending angle.
SS Butt Weld Tee
According to ends diameter, stainless steel butt weld tees can be divided into equal tees and reducing tees. Equal tee is three ends with the same diameter, while differential diameter tee is the ends with different diameters.
ASTM A403 Butt Weld Reducer
Stainless steel reducer,is a special type of stainless steel pipe fitting mainly used to connect two pipes with different diameters. According to different structures, it can be divided into stainless steel concentric reducer and eccentric reducer.
