NK-8600 In-Line Pressure Balanced Expansion Joint

Product Made in Japan
Model: NK-8600
Steelmaking, chemical, and industrial plants use expansion joints in gas and liquid transport system lines to carry substances such as air, water, gases, steam, oil, and exhaust gases. They can compensate for expansion and contraction caused by temperature differences in air-conditioning/sanitation lines in buildings and other structures. They also handle conditions such as line center misalignment, vibrations, foundation subsidence and earthquakes.
Feature
Engineers design in-line pressure balanced expansion joints to absorb axial movement and/or lateral deflection while restraining pressure thrust using tie devices that interconnect the line pressure. Each bellows set absorbs axial movement, while the line bellows typically absorb lateral deflection. Operators install this type of expansion joint in straight runs of piping.
Applicable fluid: Steam, Exhaust gas, Water, Air
Applicable bellows: MF, HF
Material: SUS304, SUS316L,
