2025-06-30 17:18:56
1. Material testing:
The materials should be based on
a) JB4730-1994 "Magnetic Particle Inspection of Steel Pressure Vessels"
c) GB/T228-2002 "Tensile Test Method for Metallic Materials at Room Temperature"
d) GB/T232-1999 "Metal Bending Test Method"
e) GB/T2650-2008 "Impact Test Method for Welded Joints"
f) GB/2651-2008 "Tensile Test Method for Welded Joints"
g) GB/T2652-2008 "Tensile testing method for welds and deposited metals"
h) GB2655-1991 "Test Method for Strain Aging Sensitivity of Welded Joints"
i) GB/T3323-2005 "Radiography of Metal Fusion Welding Joints"
Factory Test 2
a) In order to confirm compliance with this specification, the contractor shall be fully responsible for the assembly and factory testing of the equipment. The contractor shall provide a qualified report indicating all such test results.
b) The chloride content of the water used for hydrostatic testing of stainless steel components should not exceed 25ppm. The medium for the hydrostatic test of the built-in headless deaerator should be clean water, with a temperature not lower than 5 ℃ and a maximum temperature not exceeding 50 ℃. The results of the hydrostatic test should be provided as data to the contracting party.
c) The contractor shall be responsible for properly protecting the equipment to prevent damage during testing, and shall repair or replace everything directly or indirectly damaged by the testing.
d) The built-in headless deaerator should be assembled and tested in the factory as much as possible to reduce on-site preparation and testing workload. Not welding different metals on site.
3. On site testing
a) After the installation of the equipment is completed, the contracting party shall conduct tests to verify whether the specified performance is achieved
b) The temperature for on-site hydrostatic testing should not be lower than 5 ℃, and the maximum temperature should not exceed 50 ℃
c) The dissolved oxygen in the water from the built-in headless deaerator is determined by colorimetric or titration methods
d) During these tests, the contractor shall arrange qualified technical personnel to attend the verification and assist in conducting these tests
e) If the performance does not meet the requirements, the test shall be redone after adjustment and defect elimination. The contractor shall be responsible for all costs and labor for redoing the test
