The “Pipe Vacuum Frame” position is used to control pipelines and curved sections. It is especially relevant where a flat frame does not follow the geometry of the object. Typical tasks include: Pipelines, Curved surfaces, Complex sections of oil transportation infrastructure.
For this position, selection is usually carried out according to the geometry of the object, so procurement begins with the parameters of the control area. To make a request, simply send the dimensions, description of the inspection area and application conditions, after which a design from the manufacturer RUNDT is selected.
Yes. If the standard geometry is not suitable, RUNDT / TECH NK LLC can produce such a frame according to the customer’s dimensions, drawing, sketch or photo of the inspection area. This is relevant for non-standard seams, complex knots and special conditions of use.
RUNDT / TECH NK LLC provides the most complete open package of documents on serial vacuum frames, available for preliminary technical and procurement consideration. The website publishes a certificate of conformity, a title page of technical specifications, assortment materials and other confirmed information on the products of the series.
For selection, it is usually enough to send the type of product, the dimensions of the control zone, a brief description of the object, a photo of the site, a drawing or technical specification. This allows you to quickly determine whether a standard item is suitable or whether a custom product is required.

Suitable for straight sections and typical welded joints.

Used in volumetric and spatial areas.

Used on internal corners where precise frame geometry is required.
