HKS - Metal Expansion Joints and Hoses
HKS Unternehmensgruppe specializes in designing and manufacturing a diverse range of metal expansion joints and hoses, serving critical roles in various industrial applications. Their product lineup includes stainless steel expansion joints designed for optimal performance under different movement conditions such as axial, lateral, angular, and universal displacements. These joints are integral in managing thermal expansion, vibration isolation, and accommodating misalignments in piping systems. The company also offers rubber and fabric expansion joints, each tailored for specific operational needs. Emphasizing quality and precision, HKS implements rigorous testing and certification processes to ensure the reliability and longevity of their products. Their services are backed by a rapid response manufacturing capability, offering express services to meet urgent demands, and comprehensive repair options for damaged components.
Axial expansion joints are expansion joints that absorb mainly longitudinal movements axially along a straight section of pipe.
- Simple means of compensation
- Smaller space requirements
- No alteration of flow movement
- Movement possible in any direction
- No redirection of pipe work required
- Low unit costs
- High axial forces at higher pressures
- Strong fixed points and good axial pipe guides required
- Small and medium movement absorption
- For large expansion movements several axial expansion joints are required
- On long stretches many fixed points and pipe guides are required
- Connection parts : Axial expansion joints can be manufactured with weld ends, fixed flanges or swivel flanges or combinations thereof, depending on customer requirements
- Guide tubes : To avoid abrasion and turbulence (e.g. at high flow rates in pipe work systems), axial expansion joints can be equipped with inner guide tubes
- Outer protection tube : To protect the metal bellows against mechanical effects from the outside, axial expansion joints can be equipped with outer protection tubes
- One or two bellows : Axial expansion joints can be manufactures with one bellows or two bellows that are connected by a central tube (see also » Universal expansion joints)
