Product Information

Joints are a key component of gas and liquid transport lines. The flexible hoses (flexible joints) and expansion joints (pipe expansion joints) we manufacture are crucial components for maintaining line safety. Designed to save labor during line work, they reduce equipment-generated line vibrations, and handle conditions such as thermal expansion/contraction, earthquakes and uneven subsidence.

Flexible Hose

Our flexible hoses have outstanding flexibility of motion and resistance to heat, pressure and earthquakes. They support a wide range of gas and liquid transport lines for transporting substances such as air, steam, gases, water, oils and chemicals.

Expansion Joints

Our bellows expansion joints are used in gas and liquid transport system lines used by steelmaking, 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.

Other Products

Our lap joints can support a variety of steel types and lengths, with flanging done by a proprietary NFK flare forming process.Read about our joints for vacuum lines and other NFK products here.
