The new pressure test device combines three test methods in one electronic device. General test rules” individual selectable acc. requirements from the customer - The requirement from Deutsche Telekom acc. “ZTV-TKNETZ 40” - The low-pressure test acc. EN 1610:2015 as well as worksheet DWA-A-139:2009

The high-pressure test is presently the most frequent test method in the range of pressure tests for protective ducts. This test method will be performed at thick-walled protective ducts and subducts (micro ducts). With regards to the protective ducts, ducts with OD 50/40/32 mm are most frequently used application. For subducts a wider range of ducts can be tested from 7x1,5 until 20x2,5 mm. The high-pressure test distinguish between two different targets:

The DPG 17U Universal pressure test device for test of cable ducts with regards to protective ducts and subducts working in the range of 0…7 bar. The operation is made by a 7” colour-graphic-touch display. The new device support the user through a simple and menu-driven operation. With the help of a matrix (table) three different test methods can be selected. Those are “General test rules” individual selectable acc. requirements from the customer, the requirement from Deutsche Telekom acc. “ZTV-TKNETZ 40” and the low-pressure test acc. “EN 1610:2015”. This results in a maximum support for the user.

The result of the pressure test is summarized in a clear test protocol with three core areas. The test protocol will be stored on the device and can be loaded by a USB-interface to a customary PC.

Discover the new functions with the Union Connect app! You can now transfer your created PDF reports directly to your mobile phone or tablet via Bluetooth. In addition, the app enables remote control of the DPG 17U via Remote Control and the inclusion of GPS data in the log. These additional features are now available free of charge for 2 years when you purchase a new device or take advantage of services such as calibration or repair at Vetter. After the 2 years have expired, you can continue to use the functions by renewing them for a fee. Please note that the app is currently only available and released on Android devices. Stay connected and informed with the Union Connect app!

The calibration sets MKV 0810 and MKV 1116 in conjunction with the accessory micro- transmitter SKS 06 (code-no. 231941) and SKS 07 (code-no. 231954) are destined for the calibration of subducts with an internal diameter 8,0 to 16,0 mm. The calibration can be done for single subducts as well as for multi subducts. By the calibration defects or blockages on the subducts can be detected in advance thus a good blowing-in performance can be achieved. The MKV 0810 set contains two calibres with different diameters for the calibration of subducts with internal diameter 8,0 or 9,8-10,0 mm. The MKV 1116 set contains three different calibres for testing subducts of ID 11,4-16,0 mm. The calibres are easily screwed onto the micro-transmitter and blown through the subducts by air-pressure. The set also contains all essential connectors, reducing nipples as well as a catcher for the micro-transmitter. The catcher has to be used in order to avoid damages to the micro-transmitter. The air-pressure for the calibration has to be limited to max. 4 bars for MKV 0810 and to max. 2 bars for MKV 1116. By applying a higher pressure the micro-transmitter might be damaged by hitting duct blockages or by hard crashing into the catcher at the very end. The set contains the following parts:

The calibration set MKK 0606 in conjunction with the micro transmitter SKS 04 is foreseen to calibrate subducts with inner diameter D 6.0 mm only. The calibration can be performed for single subducts as well as for multi subducts in buried and protective pipe installed versions. This new calibration set supports the blowing-in of mini- and micro cables on a completely new level since the quality of a sub duct installation can be checked in general.

The set comprises of 3 calibres with protection sponge having a diameter of 4.8 mm, a collecting device for the pipe end, a spare battery cover and 2 spare batteries. The calibre will be simply unscrewed on the micro transmitter and with the sponge ahead blown-into the pipes using compressed air. The micro transmitter is a precision engineered measuring device, which has to be handled in the civil engineering with special care. Never operate the transmitter without protection sponge, bumper and collecting device fixed at the end of the pipe. Attentions should be paid to max. possible bending radius and air injection pressure - too high air pressure can cause damages on the calibration set.

During backward blowing the enclosed collecting device has to be used or at least a sufficient padding of another collecting device shall be implemented.

The catching device guarantees that the micro-transmitter is safely caught at the end of the tube and does not hit the ground unprotected.

The micro transmitter enters the catching device and is caught in the circular guide until it comes to a stop. This prevents the micro transmitter from being damaged or destroyed.

Shut-off bladders to lock off the pipeline to be tested. Shut-off bladders are used on the opposite side of the test location. The short dimensions of the Mini version allow space-saving installation of pipe bends also.

Test bladders Mini for testing and shutting off pipes for low pressure testing.

Air coupling (brass) standard for bladder extension. Air coupling (chromed) special CE-standard 10.4 mm, for inflating the duct.

Foot pump with double stroke and safety valve 2.5 bar to inflate SBM shut-off bladders and PBM test bladders. The use of a second foot pump for the second pipe end saves considerable installation time.
