Marbeyaz can produce expansion seals when required which include the sleeve type systems. Marbeyaz advanced expansion seals provide optimal longitudinal expansion for penstock pipes during the temperature changes. In order to prevent any leakages, we secure it with the stuffing box and/or apply a chrome layer on the inner packing surface to prevent corrosion and let it slip freely in the joint. Expansion seals should always be well-placed and manufactured with the precise tolerances for achieving water tightness under a high drop.
