What are the benefits of hot dip steel pipe?
What are the benefits of hot dip steel pipe? 1. The superior anti-static performance of hot dip plastic steel pipe: by adding anti-static agent to the formulation, the internal and external surface resistance can be achieved and exceed the national industry standards 2. Flame-retardant properties...Read more -
Application of pipeline eddy current testing
Application of pipeline eddy current testing Depending on the shape of the test piece and the purpose of the test, different types of coils can be used. There are usually three types of through-type, probe-type and insertion-type coils. Pass-through coils are used to detect tubes, rods and wires....Read more -
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
