Weldolet
SwsepoletQ is a contoured, integrally reinforced,
butt-weld branch connection with a low stress
intensification factor for low stresses and long
fatigue life. The attachment weld is easily ex-
amined by radiography, ultrasound and other
standard non-destructive techniques.
Insert Weldolet
---
Insert WeldoleP is another contoured butt-weld
branch connection used in less critical applica-
1 tions. Like the Swsepolet, the attachment welds
are easily examined by radiography, ultrasound
and other standard nondestructive techniques.
SockOlerO utilizes the basic Weldolet design
configuration and incorporates a socket-weld
out let.
Coupolets fittings are designed for use in fire
protection sprinkler systems and other low
pressure piping applications.
