RUNDT
Practical analyses of leak testing tasks, fixture selection and applications of RUNDT vacuum frames.
Heat exchangers
How to check the welds of a tight tube bundle when a conventional sealing collar does not fit between the tubes: real two-way tooling, inspection principle and limits of the method.

Aviation
The Vacuum Frame allows you to locally inspect a panel section, rivet joint, or opening outline prior to final assembly—without exposing the product's internal structure or filling the entire volume.

Shipbuilding
The vacuum frame helps to check the tightness of the welded joint at the stage of manufacturing a section or body block - when there is easy access to the seam and the defect can be eliminated before saturation and painting.

Oil and gas industry
Vacuum frames and the RUNDT-XR mobile unit allow you to organize local inspection of welded joints on long sections of pipelines, tank bottoms and other metal structures with one-way access.

RVS
The flat vacuum frame allows you to consistently check the welded joints of the tank bottom sheets and localize through discontinuities using bubble indication. We will analyze how to select the working length of the frame, prepare the surface and build an inspection route without gaps.

Piping
For a circumferential weld, you need a frame with a working curvature to match the outer diameter of the pipe. The coincidence of the radius and the condition of the seal determine whether the chamber can sit tightly on the surface and maintain a stable vacuum.

Custom frames
A custom frame does not start with the external dimension, but with the surface geometry and the accessible area around the joint. The more accurate the input data, the more reliably the work contour, view and handle position can be matched.
