The Pipe test cushion and sealing cushion (commonly known as test plug or sewer plugs) are suitable for easy and fast closing of sewage pipes and ducts with a circular cross section with nominal diameter of 70 mm to 1600 mm. The pipe test plugs have pass-throughs (bypass) or ventilation devices and are suitable for isolation of pipes to divert water, for filling or emptying of pipes and for filling with air or water for the leak test.
For the inspection of pipelines, which are only accessible from one side, so called household service test equipment is available. These allow the remote positioning of sealing plugs using air-sliding bars (pushing bars), which are connected together using special couplers. Complete testing sets are offered for air testing as well as the testing of household service lines using water testing according to ATV-A 143 part 6 and DIN 1986 part 30.
