Standard for industrial pipeline anti-corrosion layer, heat insulation layer and waterproof layer
Standard for industrial pipeline anti-corrosion layer, heat insulation layer and waterproof layer All metal industrial pipelines require anti-corrosion treatment, and different types of pipelines require different types of anti-corrosion treatment. The most common anti-corrosion treatment method ...Read more -
Temperature problems in the production of straight seam steel pipes
In the process of producing straight seam steel pipes, the temperature must be strictly controlled, so as to ensure the reliability of welding. If the temperature is too low, it may cause that the welding position cannot reach the temperature required for welding. In the case where most of the me...Read more -
Lubrication problems in the production of straight seam steel pipes
Straight seam steel pipes need to use a product to match in the production process, that is, a glass lubricant, which was produced with graphite before using the glass lubricant, because at that time there was no such product in the market. Therefore, graphite can only be used as a lubricant, but...Read more -
Adjustment and Control of the Position of High Frequency Induction Loop of Straight Seam Steel Tube
Straight seam steel tube excitation frequency is inversely proportional to the square root of capacitance and inductance in the excitation circuit, or proportional to the square root of voltage and current. As long as the capacitance, inductance or voltage and current in the loop are changed, the...Read more -
Factors affecting the accuracy and resolution of oil casing wall thickness detection
The API standard stipulates that the inner and outer surfaces of the imported and imported petroleum casings must not be folded, separated, cracked or scratched, and these defects should be completely removed. Petroleum casing must be fully covered for automatic wall thickness detection. Currentl...Read more -
Preparation before installation of 3PE anti-corrosive steel pipe
Before embedding 3PE anti-corrosion steel pipe, you need to clean up the surrounding environment first, and conduct technical tests on the commanders and mechanical operators who participate in the clean-up work. At least one line of defense personnel should participate in the clean-up work. It i...Read more
