Carbon Steel Backing Rings

Satterlund Supply offers a full line of carbon steel backing rings—essential for achieving full-penetration welds and consistent root reinforcement in pipe-to-pipe and pipe-to-fitting joints. Our backing rings, available in standard, large bore, and spacer designs, are precision-machined from ASTM A105 carbon steel to provide dimensional stability, corrosion resistance, and optimal heat dissipation during welding. Engineered to complement ANSI/ASME B16.25 beveling standards, these weld backing rings ensure uniform root gaps and minimize burn-through in high-pressure and high-temperature applications.

Steam Vents & Vacuum Breakers

Satterlund Supply offers a full suite of steam vents and vacuum breakers—designed to protect steam systems and maintain safe, efficient operation in boilers, heat exchangers, and condensate return lines. Our thermostatic and thermodynamic steam vents provide rapid air and condensate discharge at steam startup, while our vacuum breakers prevent damaging vacuum conditions during shutdown and cooldown cycles. Constructed from rugged brass, bronze, or stainless steel and engineered to ASME B31.1, B31.3, and ISO 6552 standards, these devices deliver leak-proof performance at pressures up to 600 psi and temperatures up to 450 °F.

Water Vents & Automatic Air Vents

Satterlund Supply offers a complete range of water vents and automatic air vents—essential for eliminating air pockets and ensuring efficient, uninterrupted flow in hydronic heating, chilled-water, and plumbing systems. Our float-type and diaphragm-type automatic air vents feature brass, bronze, or stainless steel bodies with vacuum-break functionality to continuously purge trapped air without manual intervention. Manual water vents and air-release valves are also available for isolation and maintenance operations. Engineered to ASME B31.1, B31.3, and ISO 21003 standards, these vents deliver leak-proof performance under pressures up to 300 psi and temperatures up to 400°F.
