The Access Plug Flange (APF) product line is designed to assist in Non Destructive Testing (NDT) programs on insulated and non-insulated pipe and vessels. Our extensive product line of inspection ports will allow you "to match your inspection port to your process temperature, from cryogenic to steam lines, and anything in between." This allows you to "fine tune" your safety program around your needs. We also offer a complete product line of inspection labels for all your non-insulated areas. Through our sister company, Southern Stud Weld, Inc., we can provide you with a complete line of insulation accessories like CD weld pins, self stick insulation hangers, lacing anchors and complete stud welding systems.
