Expansion test

What are the expansion testing institutions? BAIJIAN material testing agency can provide expansion testing services. BAIJIAN is a collectively owned testing institution. If you need to test metal products, you may wish to consult an engineer to understand the testing issues. BAIJIAN has multiple laboratory branches across the country, supporting nationwide door-to-door sampling/sample delivery services.

Testing fee: After the initial inspection of the sample, a quotation will be made based on the customer's testing needs and the complexity of the experiment.

Testing cycle: 7-15 working days

Expansion test range

Steel pipes, aluminum pipes, welded pipes, seamless steel pipes, heat exchange pipes, stainless steel, hollow aluminum extrusion profile welding, connecting pipes for air conditioners, high-pressure boiler pipes, piston rings, metal pipes, new energy vehicle cable metal sheaths, Fin tubes, copper and copper alloys, etc.

Expansion test items

astm expansion test, flattening expansion test, expansion test, expansion test failure analysis, expansion tooling test, expansion test cracking analysis, etc. .

BAIJIAN test report What are its functions?

1. For sales use, use third-party testing report data to prove the authenticity of your products, so that customers can trust the quality of your products more.

2. R&D use. If you encounter difficult problems during the R&D process, you can improve product quality through test report data.

3. Comparative testing to improve product quality and reduce production costs.

4. Use of scientific research paper data.

What are the advantages of BAIJIAN testing?

1. BAIJIAN is a collectively owned testing institution, Material Testing Laboratory

2. BAIJIAN has many laboratory branches across the country, supporting door-to-door sampling/sending samples for testing.

3. BAIJIAN has a short testing cycle, low testing costs, and complete experimental plans.

4. The materials laboratory has complete instruments and a strong scientific research team to ensure that your test report is scientific, fair and accurate.

5. For initial inspection of small samples, no testing fee will be charged for the initial inspection.

6. The test report supports the QR code system to check the authenticity.

BAIJIAN testing process

1. Send samples. (Communicate with engineers, submit your own testing requirements and send samples to our research institute)

2. Initial inspection samples. (After receiving the sample, conduct a preliminary inspection of the sample and formulate a detailed experimental plan)

3. Quotation. (After the initial inspection, a quotation will be made based on the customer's testing needs and the complexity of the experiment)

4. Both parties confirm, sign a confidentiality agreement, and start the experiment.

5. It takes 7-15 working days to complete the experiment.

6. Mail the test report and provide post-service.

The above is the relevant introduction to the expansion test. If you have other testing needs, you can consult the laboratory engineer.
