Application of vacuum frames and leak control units
Industries, typical tasks and industrial scenarios
This section shows where RUNDT vacuum frames and installations are used, from shipbuilding and aviation to oil and gas infrastructure, tank manufacturing and the nuclear industry.
About using RUNDT solutions
Vacuum frames and RUNDT installations are used where local control of the tightness of welds, connections, containers, pipelines and other critical areas is required.
Solutions are used in shipbuilding, aviation, oil transportation infrastructure, tank manufacturing, the nuclear industry and industrial facilities with increased quality control requirements.
Depending on the geometry of the site and site conditions, either standard frames, or special designs, or leakage control units are selected for a more mobile and organized process.
This approach allows the vacuum-bubble method to be used both in mass production and in repair, installation and field work directly on site.
RUNDT / TECH NK LLC supplies solutions as a manufacturer and helps select the design for the industry scenario, object and requirements for a set of accompanying documents.
Key industries
Aviation industry
Checking the tightness of the skin of fuselage parts, rivet joints, windows, doors and local areas of aircraft structures.
Read the material →Oil and gas infrastructure
Monitoring the tightness of process and main pipelines, tanks, piping units and equipment at oil and gas infrastructure facilities.
Read the material →Tanks
Inspection of tanks of various types and designs at enterprises producing tank equipment, including inspection of seams, bottoms, roofs and nozzle areas.
Read the material →Cryogenic systems
Monitoring of complexes of vacuum chambers, isothermal storage facilities, thermal vacuum chambers and other units where stable tightness of low-temperature systems is critical.
Nuclear industry
Vacuum frames are used to control cooling pools, production vessels, heat exchangers and other critical elements of nuclear infrastructure.
Practice Materials
Expanded industry and engineering materials. Closed customer parameters and unconfirmed test results are not published.
Aviation
Monitoring the tightness of aircraft skin elements
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
Monitoring the tightness of ship hull structures
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
Tightness monitoring of pipelines and tanks
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
Checking the tightness of tank bottom welds
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
Tightness testing of circumferential pipe weld
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
How to order a vacuum frame according to drawing and radius
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.

Heat exchangers
Checking the tightness of pipe-to-tubesheet connections
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.
Read the material →Typical tasks
- Checking the tightness of welded seams
- Tank monitoring
- Pipeline monitoring
- Inspection after refurbishment
- Control of complex areas and nodes
- Control based on the current documentation of a specific object
