A high-frequency welded pipe machine uses high-frequency electromagnetic fields to weld metal pipes. Its working principle involves generating high-frequency currents through a high-frequency power supply, rapidly heating the metal pipe to its melting point via induction heating, and fusing the contact surfaces. Thanks to the skin effect and proximity effect of high-frequency currents, heat is highly concentrated in the welding zone, resulting in rapid heating and high welding efficiency.

1. Application Scope

Vertical accumulators are primarily used in small and medium-sized high-frequency welded pipe machines, while large-scale systems are better suited for spiral accumulators.

2. Reasons for Suitability

Small and Medium-Sized Machines: These machines typically use smaller and thinner steel strips, which can move smoothly within the vertical accumulator.

Large Machines: Due to the larger size and heavier weight of steel strips, spiral accumulators are more appropriate for these systems.

3. Functions and Performance

Vertical accumulators serve as a connection to the uncoiler, storing and feeding raw materials. They typically hold 1-2 tons of material, equivalent to approximately 200 meters of steel strip. In contrast, spiral accumulators can handle 8-10 tons of material, storing up to 300 meters of steel strip.
