Pressure Testing Machine Model DPC
for hydrostatic testing of fire extinguisher cylinders and high pressure cylinders
with test pressures up to 500 bar (7112 PSI) model DPC


Expansion measurement test equipment

 

in which the pressure container are put in during the water pressure test to measure the permanent expansion in accordance with
the US - DOT regulations,
the Compressed Gas Association pamphlet C-1,
the NFPA 10 Standard for portable fire extinguisher,
the British Standard 5430 Part 3

This device consists of a container with cover into which the cylinder to be tested is placed in order to measure the expansion remaining after the pressure test.

For this purpose, the cylinder to be tested is suspended on the cover of this container with an adapter in such a way that the cylinder can freely expand in all directions.

Dimension:   approx.  diam. 300 mm X 1000 mm

The cylinder to be tested is closed with an adapter and is connected on the down side of the cover with the quick-acting coupling. The hose line and the venting line are connected on the upper side of the cover with the quick-acting coupling. There are two other connections on this cover; one for the feed of water and the other for the venting and the transfer of the water to the measuring tube ( calibrated burettes).

The measuring tube is provided with ccm scale with a accuracy of 0.1 ccm to read the water levels
in order to measure the expansion and to calculate the ratio of the total and permanent expansion.
