Swivel Joints
are flexible piping components or piping couplings made of steel, stainless steel or other materials needed in a wide range of industrial applications where:
Swivel Joints are applied in the following industrial areas and applications:
Swivel Joints are available in 8 different styles (10, 11, 12, 20, 21, 22, 30 und 31) combinable with 3 types of connecting ends (threaded, flanged and welding ends). Appropriate combination of these styles may realize almost every 3 dimensional movement.
Coming up to these and other requirements our customers select from the following choice of Swivel Joints (the types T, CF, W, LW and LA are i. a. certified according to TA-Luft):
Type W is our standard swivel joint. It is equipped with a radial sealing. The bearing has 2 marble runs for application with high outside forces or moments or very high pressures. The standard bullets are made of stainless steel.
It serves as base for customer-specific applications like operating pressures up to 1 000 bar or high-temperature applications of low-pressure range up to vacuum range (exhaust from combustion processes) or liquefied gas applications like LPG, etc.
There can be used for a variety of fluids. Our customers select the materials for cabinets, sealings and bearings according to the specification.
Such connections as pipe nozzles or pipe elbows, threads and flanges are available. Customer-specific connections can be installed alternatively.
