Flexible Ball Joints Engineered for Performance
ATS flexible ball joints are designed to accommodate angular and rotational movement in demanding piping applications. Built to perform in both high-temperature and low-temperature environments, these joints help reduce system stress while maintaining leak-free operation. Our ball joints are commonly used in thermal piping systems where flexibility, durability, and long service life are critical.
Packed Slip Type Expansion Joints
Our packed slip type expansion joints are a cornerstone of the ATS product lineup. Designed to absorb thermal expansion and contraction, these joints reduce stress on piping systems and help prevent premature failure. Known for their rugged construction and reliable sealing performance, ATS expansion joints are engineered to handle the most demanding industrial environments.
Complete Piping System Solutions
In addition to expansion joints and ball joints, ATS offers a full range of complementary piping components, including:
- Low friction pipe supports and guides designed to allow controlled movement while reducing wear
- Pipe guides and anchors that maintain alignment and protect piping systems from unwanted displacement
- Pre-engineered anchors for strength, stability, and faster installation
- Insulation blankets to improve system efficiency and protect personnel
Together, these solutions help extend system life, improve safety, and optimize overall performance.
