home About company Manufactured products Information Contacts Products / Compensators Compensators are designed to compensate for displacements, thermal expansion, vibration absorption, and reduction of internal and external noise levels. The company produces expansion joints that are used both in the automotive industry (in the exhaust system on engines) and in other industries (oil, gas, chemical). The main component of the expansion joint is a flexible bellows-type corrugated casing (see Fig. 1), which is made of stainless steel. Details of connecting fittings are made of carbon steel. The advantage of using flexible bellows is high tightness. As the wall thickness of the bellows increases, the pressure resistance increases. Compensators distinguish between: by the type of bellows - single-layer (S = 0.25mm, S = 0.4mm) and two-layer (S = 2x0.25mm); by the type of connection - flange connection, or welding fittings; by the presence of an internal protective screen - with or without an internal screen. The internal protective screen is used when operating at high temperatures, as well as to reduce the vortices of the gas flow inside the bellows and, as a result, to reduce the resistance. To increase the strength and protect the expansion joints from mechanical damage, a braid can be used, which is made of stainless steel wire with a diameter of 0.4 mm. Main parameters and characteristics: Working environment temperature (combustion products of automobile engines) - up to + 850 ºС. Ambient temperature - from + 50˚С to minus 45 ˚С. Tightness at overpressure - 45 kPa. All rights reserved © 2009 "Maksprom" - manufacture of components for cars Website development in Ufa "Express Lab"
