NFK NK-8700 Pressure Balanced Expansion Joint
Product Made in Japan
Manufacturer: NFK
Model: NK-8700
NFK expansion joints are used in gas and liquid transport system lines used by steel making, chemical and industrial plants to transport 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
A pressure balanced Expansion joint is designed to absorb axial movement and/or lateral deflection while restraining the pressure thrust by means of tie devices interconnecting the flow bellows with an opposed bellows also subjected to the line.
Applicable fluid: Steam, Exhaust gas, Water, Air
Applicable bellows: MF, HF
Material: SUS304, SUS316L,
