GB 150 steel pressure vessels
JB/T 4730.5 Non-destructive testing of pressure equipments - Part 5. penetrant testing
The first three test preparation
3.1 Check lining layer and the inner member of welded joints
3.1.1 backing layer and the inner member of all macroscopic examination should be carried out after welding, the welded joint surface shall comply with the requirements of GB 150.
3.1.2 backing layer all welded joints shall be subject to 100% penetration testing qualified, according to the provisions of penetrant testing JB/T 4730.5 of.
Cleanup 3.2 Test site
All the oil surface and welded joints on both sides of the backing layer, an alkaline substance and colored reagent residue should be cleaned, the cleaning agent from chlorine
Sub content should not exceed 25mg/L.
4 test device
4.1 test device
Ammonia leak test should have the following means. a bottle of ammonia, nitrogen bottles, ammonia pressure gauge, vacuum gauge, valves, globe valves, pumps, tanks,
U-tubing, high pressure hose and phenolphthalein test paper and the like.
4.2 Test and test equipment considerations
4.2.1 All connections, valves should not leak tight, safe and reliable.
4.2.2 bottles of ammonia, nitrogen bottle should immediately be set, not lying down.
4.2.3 installed on the device, and at least two of the same range after checking qualified ammonia pressure gauge or vacuum gauge, dial diameter not less than 100mm,
Ammonia pressure gauge range is 1.5 times to 3.0 times the test pressure.
5 Test methods
5.1 vacuum method (A method)
5.1.1 This method is charged 100% of the ammonia, ammonia leak test for the high-pressure pipe heat exchanger tank lining layer of welded joints.
5.1.2 Test procedure.
a) Figure Prepare and connect the necessary equipment and accessories, instruments and tools 1. Each liner connection points (A1, A2, A3
