The purpose of high-frequency welded pipes is welded pipes. Straight seam high-frequency welded steel pipes have the characteristics of relatively simple process and rapid continuous production. They are widely used in civil construction, petrochemical, light industry and other departments. They are mostly used to transport low-pressure fluids or make various projects. Components and light industrial products.
High-frequency welding is based on the principle of electromagnetic induction and the skin effect, proximity effect and eddy current thermal effect of AC charges in the conductor, which causes the steel at the edge of the weld to be locally heated to a molten state. After being extruded by the roller, the butt weld is inter-crystalline. High-frequency welding is a kind of induction welding (or pressure contact welding). It does not require weld filler, has no welding spatter, has a narrow welding heat-affected zone, beautiful welding shape, and good welding mechanical properties. and other advantages, so it is widely used in the production of steel pipes.
What is the difference in appearance between high-frequency welded pipe and welded pipe?
High-frequency welded pipes are a type of welded steel pipes, so there are certain differences between high-frequency welded pipes and collectively referred to as welded steel pipes, but they are the same in terms of broad categories.
High-frequency welded pipes are divided into the following four types:
1. Welded steel pipes for low-pressure fluid transportation are also called general welded pipes, commonly known as black pipes.
2. Galvanized welded steel pipes for low-pressure fluid transportation are also called galvanized electric welded steel pipes, commonly known as white pipes.
3. Ordinary carbon steel wire sleeves are steel pipes used to protect wires in electrical installation projects such as industrial and civil buildings and installation of machinery and equipment.
4. Straight seam electric welded steel pipe is a steel pipe in which the weld seam is parallel to the longitudinal direction of the steel pipe.
Steel pipes are generally divided into two categories, one is called welded steel pipes, and the other is seamless steel pipes. Welded steel pipes, also called welded pipes, are steel pipes made of steel plates or strips that are welded after being curled and formed. Welded pipes are divided into: straight Seam welded pipe and spiral welded pipe
Different materials are divided into: galvanized welded steel pipes, stainless steel welded steel pipes, of course! The surface quality and dimensional tolerances of welded pipes produced by different materials and different processes are different.
