About RUNDT vacuum frames
RUNDT vacuum frames are used for testing the tightness of welds, tanks, pipelines, housings, containers and other structures where local testing by the vacuum bubble method is required.
The range includes standard flat frames, overlap frames, internal and external corner frames, round, square, tube, triangular and spatial designs. For each type, the shape of the working area, standard size and configuration are selected for a specific inspection area.
The page contains the main standard items, standard sizes, product photographs and links to individual product pages. The current cost and delivery time can be requested through the website form.
Confirmed documents are available for serial products, including a certificate of conformity, cover sheet of technical specifications, assortment and materials for standard items. If an object requires an individual solution, it is possible to manufacture vacuum frames to order according to dimensions, drawings or technical specifications.
Vacuum frames are used in industry, shipbuilding, tank production, pipelines, heat exchangers and other critical facilities. The selection of a suitable design depends on the shape of the controlled area, the location of the joint, surface accessibility and site operating conditions.

Questions about vacuum seal frames
What is a Vacuum Sealing Frame?
Vacuum leak testing frame is used in the vacuum bubble method for local inspection of welds, joints, tanks, pipelines and other critical areas. It forms a working control zone and helps to detect leaks by characteristic bubble formation.
How to choose a vacuum frame for a weld, tank or pipeline?
The selection of a vacuum frame depends on the shape of the area being inspected, the geometry of the seam, the size of the inspection area, surface accessibility and working conditions at the site. For flat areas, standard rectangular designs are usually chosen, for corners and overlaps special shapes are used, and for pipes and complex assemblies, profile or custom solutions are used.
Are there standard vacuum frames and how do you usually purchase them?
Yes, the website shows confirmed standard types and sizes of RUNDT vacuum frames. For the main serial items, standard frames are almost always present in stock or in the production program. For a purchasing request, it is usually sufficient to specify the frame type, standard size and inspection task.
Is it possible to order a vacuum frame according to my dimensions?
Yes, if the standard vacuum frame does not suit the shape, length, width or application conditions, a custom version is made to order. For calculations, it is usually enough to send dimensions, a photo of the control area, a sketch, drawing or a brief technical description of the object.
What documents are available for RUNDT vacuum frames from the manufacturer?
RUNDT / TECH NK LLC provides the most complete open package of documents on serial vacuum frames, available on the website for initial technical and procurement consideration. It includes a certificate of conformity, a title page of technical specifications, assortment materials and confirmed information on standard items.
