Can galvanized pipe inspection be done? What are the testing items and standards for galvanized pipes? How much does galvanized pipe coating thickness testing cost? How long does it take for a galvanized pipe inspection report to be issued? Foshan Huajin's third-party material testing laboratory can provide all kinds of galvanized pipe testing services, including quality testing, composition testing, coating thickness, salt spray testing, tensile testing, metallographic analysis, RoHS testing, etc. As a third-party testing center, the institution has CMA, CNAS certification and testing qualifications, complete testing equipment, scientific and reliable data, and can issue a nationally recognized galvanized pipe test report within 5-10 working days.
As a common metal pipe, galvanized pipe is widely used in construction, water supply and drainage, petrochemical and other industries. In order to ensure that the quality and performance of galvanized pipes meet the requirements, many enterprises will choose to send them to professional testing institutions for testing before purchasing and using. How much does it cost to do galvanized pipe testing at a testing institution?
1. The significance of the galvanized pipe test report
1.Ensure the qualification of the quality of galvanized pipes.
2.Ensure the safety and durability of galvanized pipes in use.
3.Provide technical basis and practical experience to support the quality control and improvement of galvanized pipes.
2. Common galvanized pipe testing methods:
The detection method of galvanized pipe is as follows:
1. Uniformity of galvanized layer. The steel pipe specimen is immersed in copper sulfate solution for 5 consecutive times and does not turn red (copper plating).
2. Cold bending test. Galvanized steel pipes with a nominal diameter of not more than 50mm should be subjected to cold bending test. The bending angle is 90° and the bending radius is 8 times the outer diameter.
3. Hydrostatic test. The hydrostatic test should be carried out in the black pipe, and eddy current testing can also be used instead of the hydrostatic test.
In addition, there are also appearance quality, section morphology, chemical composition analysis, metallographic inspection, hardness test and other testing methods.
3. The testing items of galvanized pipes generally include the following aspects:
Appearance inspection: mainly check the surface with ** thorns, zinc layer adhesion, surface flatness and poor deformation.
Size inspection: mainly check whether the wall thickness, outer diameter, length and other dimensions of the steel pipe meet the standard specifications.
Chemical composition analysis: It is mainly used to check whether the chemical composition of steel pipes meets the requirements of standard specifications.
Mechanical property test: mainly includes tensile test and bending test, etc., which are used to check whether the mechanical properties of the steel pipe meet the requirements of the standard specification.
Other items: coating thickness, coating weight, coating adhesion, hardness, metallographic testing, non-destructive testing, failure analysis, salt spray test, environmental protection RoHS testing, coating composition testing, etc.
It should be made clear that the ** of galvanized pipe testing is determined according to different testing items and standards. Common galvanized pipe testing items include appearance quality testing, thickness measurement, coating adhesion testing, chemical composition testing, mechanical property testing, etc. The equipment, technology, and cost required for different testing programs vary, so will they.
Different testing institutions will also have different charging standards. Large-scale testing institutions are usually relatively high, because their equipment and technology are relatively advanced, and the quality of personnel is high. Some small testing institutions may be relatively low, but there may be certain limitations in terms of equipment and technology.
The location of the testing facility also needs to be considered. Generally speaking, testing institutions** located in first-tier cities or developed areas are generally higher because of higher labor costs and operating costs. However, the number of testing institutions** located in second-tier cities or economically underdeveloped areas is relatively low.
According to market research and related information, the current galvanized pipe testing is roughly between 1,000 yuan and 3,000 yuan. The specific ** also depends on the specific test items and testing requirements. If you need to detect multiple items at the same time, ** will increase accordingly. There are also some testing institutions that will price according to factors such as the specification, length and quantity of pipes. Generally speaking, large quantities of testing can enjoy certain discounts.
Galvanized pipe inspection and inspection process:
1. Fill in the application form: contact Huajin testing staff to confirm the testing standards and projects, and sign the power of attorney.
2. Arrange to send samples: send the samples by express or directly to our laboratory.
3. Product testing: After payment, the laboratory arranges testing and issues a draft report.
4. Confirm the draft report and issue a formal report.
5. Report bill delivery service, as well as report interpretation and after-sales service.
The above is the relevant introduction of Huajin Testing on galvanized pipe testing services, more about galvanized pipe testing costs, standards, projects, cycles and other issues can be consulted by consulting ** engineer or call us. (Test The testing cycle, method and steps are subject to the engineer, if the sample is special, you can communicate with the engineer about the particularity of the sample, and the institution can design a reasonable testing and analysis plan for you to save your time).
