BAIJIAN - Third party testing organization
What are the general testing methods for seamless copper alloy pipes? What are the testing standards? What is the cost? The laboratory of the Hundred Inspection and Testing Research Institute can develop test plans based on relevant standards. Conduct testing and analysis on tensile strength、 elongation after fracture、 expansion test、 flattening test、 residual stress test、 and other items. And issue a rigorous and impartial inspection report for copper alloy seamless pipes. Test items include chemical composition、 dimensional deviation、 tensile strength、 elongation after fracture、 flaring test、 flattening test、 residual stress test、 eddy current inspection、 water pressure test、 pneumatic test、 grain size test、 and surface quality test. Scope of application: Copper alloy seamless pipes、 etc. Relevant Testing Standards GB/T 8890-2015 Copper Alloy Seamless Pipe for Heat Exchangers GB/T 31977-2015 Copper Alloy Seamless Pipe for Nuclear Power Condensers JB 4742-2000 Nickel Copper Alloy Seamless Pipe for Pressure Vessels GB/T 23609-2009 Copper Alloy Seamless Pipe for Seawater Desalination Equipment GB/T 27672-2011 Copper and Copper Alloy Seamless Pipe for Welding and Cutting CNS 5127-1991 Copper and Copper Alloy Seamless Pipe GB/T 5248-2008 Eddy Current Testing Method for Copper and Copper Alloy Seamless Pipe GB/T 19447-2004 for Heat Exchangers Copper and Copper Alloy Seamless Finned Tubes GB/T 26024-2010 Copper and Copper Alloy Seamless Tubes for Valves in Air Conditioning and Refrigeration Systems GB/T 16866-2006 Copper and Copper Alloy Seamless Tubes - External Dimensions and Permissible Deviations - Purpose of Handling Inspection Reports: 1. Evaluate the Quality of Products; 2. Determine the product quality level、 i.e. the severity of defects; 3. Inspect the process flow and supervise the process quality; 4. Collect、 statistics、 and analyze quality data to lay the foundation for quality improvement and management activities; 5. Introduce arbitration inspection to determine the responsibility for quality accidents. Precautions for testing reports: 1. If there is no "research and testing special seal" or official seal in the report、 the report is invalid without anti-counterfeiting QR code; 2. The copied report is invalid without the "Research and Testing Special Seal" or the official seal; 3. The report is invalid without the signature of the main inspector、 reviewer、 and approver; 4. The altered report is invalid; 5. If there are any objections to the testing report、 they should be raised within 15 days after receiving the report、 and will not be accepted after the deadline; The above article is a partial list.
