With threaded ends and flanged valves size range from DN 15 (1/2") - DN 400 (16"),
Test pressure up to 5000psi (gas) or 9000psi (water), test media Water, Nitrogen.
According to the international test standard API, ISO, and DIN.
For the original of main components of the test bench, pumps and booster are
The products of the United States of America. High pressure valves are
The products of the Switzerland.
1. Gas and Water Test Bench Specifications
50: 1 ratio air-driven booster used the minimum precharge pressure 400psi,
The max output pressure up to 4300psi.
One high pressure gas regulator used.
100: 1 ratio air-driven pump used the max output pressure up to 9000psi.
High pressure nitrogen bottles can be used as the precharge gas to
Get high pressure test media.
100 psi air compressor can be used to supply driving air.
Gauges: "three pieces φ150 dial panel-mounted gauges, 0.4% accuracy full scale, 10000psi, 5000psi and 1000psi.
An auxiliary gauge port is provided with quick disconnects for other gauge range.
All high pressure valves, tubing and fittings are stainless steels.
All gauges, valves and regulators are panel mounted.
2. Clamping Equipment
Clamping equipment is used for testing with water and nitrogen including
Two clamping units (DN15-200, DN200-400).
The heavy duty constructed automatic clamping system with
A double acting hydraulic cylinder
Which is operated from the control panel.
