Henan Liwei Industry Co., Ltd. is a professional manufacturer of water supply and drainage materials. Our main products include Single/Double Sphere Rubber Joint, expansion joint, Ball Joint, Flange, steel dismantling joint, Carbon Steel/Stainless Steel Metal Expansion Joints, Fabric Expansion Joints, valve parts, pipe parts, various kinds of stainless steel compensators, duct fabric compensators, advanced soft sealing gate valves and flange butterfly valve.

Air duct rubber compensator is divided into FDZ, FVB, FUB, XB, four kinds of models. By the composition Rubber and rubber fabric composite material, Steel flanges, sleeve, heat preservation and heat insulation material. Mainly used for a variety of flexible connection between the fan and duct. Its function is to sealing, shock absorption, noise reduction, medium resistance, displacement and makes the pipes easier to install. It is a kind of very ideal environmental protection field shock absorption, noise reduction, the best accessories and smoke prevention and dust control.

The rubber and fabric Good displacement (change) reducing over and over again. Can provide larger multidimensional in smaller size range direction compensation. Can eliminate the multidirectional errors caused by all kinds of piping connection.

Rubber and fiber fabric has excellent acoustical isolation function. Can effectively reduce and eliminate boiler, fan system such as the transmission of sound and vibration.

Rubber and fiber woven force transmission loss to reduce the design procedure, without adding other auxiliary facilities.

Rubber and fiber fabric and heat insulation material with high heat resistance and corrosion resistance. Never rust, reduce maintenance costs.

Rubber and fiber fabric has excellent air tightness and kindliness, Can guarantee the transmission medium and restorable after repeated displacement without leakage.
