| Stainless Steel Weldolet
Weldolets are the most common branch connection and are considered a butt-welded fitting because they are beveled at the end and butt-welded to a straight pipe. Butt-welded branch seats are designed to minimize stress concentrations and provide overall reinforcement.
| Advantage
Good corrosion resistance
High strength and pressure resistance
Good hygienic performance
Easy to install&Economy
