Leak Testing Equipment Clam-Shell Hydrogen And Nitrogen Leak Detection System
Overview:
This protocol describes a clam-shell hydrogen and nitrogen leak detection system for piping leak detection. This test system consists of:
(1) One hose
(2) One test bench with two test stations
(3) Fixtures for two kinds of workpiece. Leak Testing Equipment
Technical Parameter:
| Test Workpiece | Refrigeration pipeline, refrigeration components |
| Detection Method | Clam-shell method. The test system has 2 test modes for option: 1. The entire workpiece is detected together, no need to find the leak point. 2. Each weld of the workpiece is detected in turn, and the leak point is known. |
| Detectable leak rate of leak detector | 1x10-7 Pa. m³/s |
| Alarm leak rate | 1x10-6 Pa. m³/s |
| Gas for gross detection | Nitrogen Leak Testing Equipment |
| Gas pressure for gross leak detection | 450 psi (downward adjustable) |
| Gas for fine leak detection | Hydrogen & Nitrogen |
| Gas pressure for fine leak detection | 250 psi (downward adjustable) |
| Test bench | 1 test bench with 2 test stations, each test station can test 1 workpiece |
| Quantity of fixtures | One set for each workpiece, total 2 sets |
| Workpiece loading & unloading | Manually |
| Test cycle | 300 sets / 10 hours |
