Pipeline Network Inspection Services

Continuous testing verifies extensive knowledge of gas detection work, the existence of the relevant rules and regulations and other regulations and checks them externally. Gas pipe network operators who check their pipeline system in-house are very welcome to obtain the necessary hardware and software from us.

Benefit from our many years of experience in gas pipe network control. Schütz Messtechnik, as a reliable partner in pipe network inspection, offers you recognized and leading state-of-the-art hardware and software technology as well as the security of a service provider certified by DVGW according to ISO 9000.

Complete systems from Schütz Messtechnik

• Tried and tested hardware that is qualified in practice
• Set up and test the system
• Complete test including detection device

Energy suppliers who use a geographic information system (GIS) can have their network checked using digital technology from Schütz.

Use of digital plans

The management of all pipe network information with a geographic information system (GIS) is already standard for modern energy supply companies. However, the regular gas pipe network inspection is often still carried out in the conventional manner with plans on paper. Printing out and assembling the plans, handling the plans by the gas detector during the control and manual entry of the data obtained during the review are work steps that - time-consuming and expensive - still have to be carried out with the previous working method.

If you want to take full advantage of your GIS, Schütz Messetechnik now offers you a modern, inexpensive and at the same time safe alternative for gas pipe network inspection. Equipped with an electronic field information system, the gas detectors from Schütz are able to have the entire plan digitally available on site. The network operator only needs to provide the relevant plan sections on a USB stick.

The gas detector can read the data into a field-compatible computer and use it directly when inspecting the line. With the help of a GPS receiver (= Global Positioning System) the gas detector can determine his position and automatically follow the plan. An electronic damage sketch in accordance with DVGW can be created and completed for documentation of any damage that appears during the inspection.

Advantages of an electronically supported gas pipe network inspection

• You take full advantage of the possibilities of your GIS
• You reduce your effort considerably
• You increase efficiency and security through digital documentation
• You create better predictability and advantages for your work preparation
• You significantly increase the quality of the documentation

Checklist for Data Exchange

• Send sample data for review before the start of the job
• Determine the visibility as required for the pipeline network inspection
• Make sure the dimensions are easy to read (height approx.1.3m)
• Highlight the gas pipe clearly, if possible red
• For graphic data, reduce the number of colors to 16
• For dxf data, use an older format (e.g. dxf 14)
• For dwg data, use an older format (e.g. dwg 14)
• The dxf or dwg file size should not exceed 50 to 80MB
• Send data to us at least 2 weeks before the start of work

DXF DWG Data Exchange

With vector data formats (dxf, dwg ..) problems and processing time and again arise due to many special adaptations and interfaces used. As an example, the use of blocks in dwg (ACAD) format, these blocks have to be resolved during export, otherwise the visualization is no longer saved.
The Following Issues are Often a Cause for Manual Post-Processing

• Special characters coding, for example umlauts are no longer displayed
• Blocks are not resolved
• The thickness of the line is too narrow and cannot be seen on the portable device
• The color of the cable is not suitable and cannot be recognized on the portable device
• The files are too large and can no longer be loaded
• Dimensions too small are no longer legible

Only in exceptional cases can dxf dwg or other vector data be used without post-processing. Alternatively, the data can already be tiled, but processing is then no longer possible, so the necessary specifications for using the plan on a tablet PC for the above-ground inspection of the gas pipe network must be met.
