Product specification and description
2024 aluminum pipe corrosion resistance is not high, often using anodizing treatment and painting method or surface coated with aluminum layer to improve its corrosion resistance.
Our inspection of steel pipes generally includes: inspection of geometric size and surface quality: inspection of chemical composition, mechanical properties, technological properties, inspection of high-low tissue: non-destructive testing: inspection of some special properties and length measurement and weighing.
(1) Check the geometric size of the steel pipe
The outer diameter, wall thickness, bending degree and length of the steel pipe are checked on the inspection table with external calipers, micrometers, bending degree and length winding.
Sometimes, the outer diameter, wall thickness and length are also continuously tested by automatic size detection devices (such as automatic diameter measurement, thickness measurement, length measurement devices). For OCTG steel pipe also need to check the thread parameters.
(2) Check the inner and outer surfaces of the steel pipe
We generally use visual inspection for internal and external surface inspection, and in addition to visual inspection, the internal surface is also inspected by reflection prism. Some special purpose steel pipes also require non-destructive testing, including eddy current, magnetic leakage, ultrasonic, magnetic particle testing, etc., to check the quality of the inner and outer surface of the steel pipe.
(3) Mechanical properties and process performance inspection
In order to verify that the mechanical properties of the steel pipe meet the requirements of the standard, we need to conduct mechanical properties inspection on the steel pipe sampling.
The test of mechanical properties mainly includes tensile strength, yield strength, elongation, impact work, etc. The process performance test mainly includes flattening test, flaring test, water pressure test, flange test, cold bending test, perforating test and so on. These inspection items are selected according to the different standards and the difference in the use of the steel pipe.
(4) Non-destructive inspection
Our non-destructive testing methods include: magnetic leakage testing, ultrasonic testing, eddy current and fluorescent magnetic particle testing, ultrasonic spectrum analysis testing, ultrasonic imaging testing and ultrasonic high temperature testing
Material introduction
Aluminum is a light, malleable, silvery-white metal with many excellent properties. It has a low density of only about 2.7 g/cm³ and is therefore a lightweight material. Aluminum has good thermal and electrical conductivity and can be used to manufacture a variety of high-precision parts and components. In addition, aluminum also has good corrosion resistance and can remain stable in a variety of environments.
Aluminum has a melting point of 660 ° C and a boiling point of 2327 ° C, so it can be widely used in various industrial fields. Aluminum is an important structural material that can be used to manufacture a variety of aircraft, cars, ships and other vehicles. In addition, aluminum can also be used to manufacture various building structures, plumbing systems, etc.
The chemical properties of aluminum are relatively stable, but oxidation reactions may occur under certain circumstances. In daily life, aluminum products are very common, such as aluminum cans, aluminum bottle caps and so on. These products have been specially treated during the production process to ensure that they have good stability and durability during use.
Although aluminum has many advantages, excessive intake of aluminum may also have negative effects on human health. Therefore, when using aluminum products, attention should be paid to controlling the amount of use to avoid long-term exposure to or use of high-concentration aluminum products. At the same time, effective measures should also be taken in the production process to reduce the impact of aluminum on the environment.
In short, aluminum is an important metal material and has a wide range of application prospects. In the process of use, attention should be paid to controlling the amount and mode of use to avoid adverse effects on human health and the environment.
