October 2007Vibration test (1)Test Nr.: 002/2006Date: 16.02.2006Test items PRIMOFIT: 2 pcs. female adaptors 1”2 pcs. couplings 1” 2 pcs. elbows 1”5 pcs. steel pipes 1” EN 10255Conditions:el

2、ectric motor 1.200 rmptest duration 15 minuteswater pressure 70 barOctober 2007Vibration test (2)Results:After 15 minutes continuous vibration testing:no leakage at pipesno leakage at PRIMOFIT compression fittings test passed!October 2007Pressure and tensile test steel pipe (1)Test Nr.: 004/2005Date

3、: 24.10.2005Test items PRIMOFIT: 2 pcs. female adaptors 1”1 pcs. steel pipe 1” EN 10255Pressure test:slow pressure increase in 5bar steps up to 220barResult:first leakage at 200bar! test passed!October 2007Pressure and tensile test steel pipe (2)Tensile test:tested items are the same which were used

4、 in pressure testpull speed 0,416mm/sResult:the pipe was pulled out of the fitting in the length of 6mmat a tensile force of73,74kN ( 7 tons!) test passed!October 2007Pressure and tensile test PE-X pipe (1)Test Nr.: 020/2007Date: 13.03.2007Test items PRIMOFIT: 2 pcs. female adaptors 1 ” / 40mm1 pcs.

5、 PE-X pipe 40mmTensile test:pull speed 0,416mm/sResult:test was stopped at a tensile force of 8,97kN (900kg) because only the pipe moved and the fittings stayed in position test passed!October 2007Pressure and tensile test PE-X pipe (2)Pressure test:tested items are the same which were used in tensi

6、le testslow pressure increase up to 10, 25, 45 and 55 barResult:up to a pressure of 55bar the connections remained leak-tight but the PE-X pipe burstdismantling of the assembly shows the grooves in the PE-X pipe done by the locking ring test passed!October 2007Pressure and tensile test copper pipe,

7、locking ring for steel pipes (1)Pressure testTest Nr.: 023/2007Date: 16.07.2007Test items PRIMOFIT: 2 pcs. female adaptors” / 20mm with locking ring for steel2 pcs. inside stiffeners 19,6mm; trimmed at shoulder to 21mm1 pcs. copper pipe 22mm (wall thickness 1mm)Result:during test no axial movementsa

8、t a pressure of 234,6 bar! the copper pipe burst, no leakage around the Primofits test passed!October 2007Pressure and tensile test copper pipe, locking ring for steel pipes (2)Tensile testTest Nr. 024/2007, Date 17.07.2007Test items PRIMOFIT: 2 pcs. fem. adaptors ” / 20mm with locking ring for stee

9、l2 pcs. inside stiffeners 19,6mm; trimmed at shoulder to 21mm1 pcs. copper pipe 22mm (wall thickness 1mm)Result:at a tensile force of 6,9kN (700kg) the pipe started to move, test was stopped at 11,3kN (1.100kg)the huge tensile force caused damages onto the copper pipe Test passed!October 2007Assembl

10、y test copper pipe without inside stiffenerAssembly testTest Nr.: 029/2007Date: 23.07.2007Test items PRIMOFIT: 2 pcs. female adaptors” / 20mm, locking ring steel1 pcs. copper pipe 22mm (wall thickness 1mm)Result:assembling without an inside stiffener causes a damage onto the copper pipe Test failed!

11、With stiffener:October 2007Summary PRIMOFIT for use with copper pipesTests done with copper pipes received from VG NL15mm and 18mm copper pipesnot possible with existing parts (diameter too small)development would be necessary (quantities?)22mm copper pipes - test passed with following conditions:bo

12、dy and nut:for tests standard parts were usedfor daily use it could be difficult to insert the pipe due to narrow tolerances (inner diameter body and nut = 21,9+0,5mm, outer diameter pipe = 22mm) a modification of the body and nut will be necessarylocking ring for steel pipes, washer for steel pipes, seal:standard parts can be usedinside stiffenerstandard stiffener for PE 2
