This is the aluminum-plated zinc tube our company recently sent to the UAE, which needs to be inspected before delivery, so as to ensure the quality of the goods and the customer will rest assured
Aluminized zinc pipe is a kind of steel pipe with anti-corrosion properties, in order to ensure its quality, a series of inspections need to be carried out before delivery. The following are the general steps for shipment inspection of aluminized zinc tubes:
Appearance inspection: Check whether the surface of the aluminum-plated zinc tube is smooth, without cracks, dents, scratches and other defects, whether there is coating peeling, oxidation and other phenomena.
Size measurement: Measure the length, diameter, wall thickness and other dimensions of the aluminized zinc tube, and compare it with the technical requirements to ensure that the size meets the standard.
Chemical composition analysis: Collect material samples of aluminum-plated zinc tubes, and test whether the composition and thickness of the coating meet the requirements through chemical analysis.
Thickness measurement: The thickness of the coating is measured using a tool such as a metallographic microscope to ensure that it meets the standard requirements.
Corrosion performance test: through salt spray test, humidity test and other methods to evaluate the corrosion resistance of aluminum-plated zinc tube.
Structural performance test: tensile, bending and other tests are used to test the mechanical properties of aluminum-plated zinc tubes to evaluate their strength and reliability.
Surface coating inspection: Check the adhesion and hardness of the surface coating of the aluminized zinc tube to ensure that the coating quality is good.
