Abstract
Abstract A TESTING APPARATUS FOR PIPES WHEREIN THE TESTING HEADS WHICH ENGAGE THE END PORTIONS OF A PIPE DURING TESTING WITH A FLUID ARE INSERTABLE INTO THE CHAMBERS FOR ALIGNED STATIONARY OR INDEXIBLE SUPPORTS AND ARE PROVIDED WITH SEALING RINGS WHICH ENGAGE THE CIRCUMFERENCES OR THE END FACES OF PIPES DURING TESTING. THE POSITIONS OF SEALING RINGS AND FLUID CONVEYING PASSAGES IN THE TESTING HEADS ARE SELECTED IN SUCH A WAY THAT THE PARTS WHICH SUPPORT AND CLAMP INTERMEDIATE PORTIONS OF PIPES DURING TESTING REQUIRE MINOR ADJUSTMENTS WHEN A LARGER-DIAMETER PIPE IS TESTED AFTER A SMALLER-DIAMETER PIPE OR VICE VERSA.
