HW 2100 K-424 Thermal Oil Rotary Joint
HW2100 K 424 thermal Oil rotary joint is a replacement for Maier units.
It adopts a dualpassage flangeconnected structure with carbon steel main body.
The flange and elbow are formed by welding.
Equipped with balanced mechanical seals, it is designed for continuous rotary media transfer under hightemperature hotoil working conditions.
It is wellsuited for rotary pipeline retrofitting and sparepart replacement of various hotoil heatexchange equipment.

FAQ
A: The flange and elbow are welded and processed before delivery. Avoid excessive equipment vibration as well as sharp temperature rises or drops in field operation to minimize impact load on welds.
A: Operation at 100 RPM is permitted. For long-term full-speed running, avoid operating at maximum pressure and maximum temperature simultaneously. Perform regular inspection to check seal leakage.
