Shandong seamless steel tube factory for: What is the difference between seamless steel tubes and ordinary steel tubes? Seamless steel tubes and ordinary steel tubes have a distinct difference in terms of manufacturing process, whether in welding, or in process forming, chemical composition, tensile strength Degrees and other production processes, the difference between the two have different differences.

Ordinary steel pipes are generally welded by bending the plate material, and a welding seam can be found on the surface; a thicker one is generally a spiral welding seam.
Seamless steel pipes are generally formed by the molten steel in a molten state being accumulated in a ring slit and then processed by drawing and other treatment processes, so that there is no weld seam. In terms of performance, especially the pressure bearing capacity is greatly improved compared with ordinary steel pipes, so it is often used for high pressure equipment. Such as hydraulic equipment, such as pipeline connections. The weld part of the ordinary steel pipe is its weak link, and the weld quality is also the main factor affecting its overall performance. People who have lived in the South have generally experienced the thawing of water pipes or heating pipes in the winter. The places where explosions occur are generally welded seams. Welded pipes are not seamless steel pipes.

Electric mosquito swatter is a kind of small household appliance products, mainly used to kill mosquitoes, flies, moths and other insects. It through the electronic high voltage technology, the use of 1850V high voltage to effectively destroy these pests, has the advantages of practical, convenient, no chemical pollution, safety and health, so it is widely welcomed, become the summer best-selling small household appliances products. The electric mosquito bat is usually composed of three layers of metal mesh, the outer metal mesh and the middle layer are not directly connected, and maintain a certain distance. When the switch is pressed, the direct current in the battery passes through the oscillation circuit and the boost circuit, eventually reaching a high voltage above 2000 volts. This design allows the mosquito to be waved through the electrostatic field and electrical grid discharge to destroy the insect, without causing harm to the human body.
The main advantages of electric mosquito swatting include:
Efficient pest control: can kill a variety of insects in a short time, including mosquitoes, flies and moths.
Safety and health: the use of high voltage electricity instead of chemical agents, to avoid chemical pollution, more environmental protection and safety.
Portable and convenient: compact size, easy to carry and use, suitable for home and outdoor use.
No chemical pollution: will not produce harmful chemicals, more friendly to the environment and human body.
The following points should be noted when using an electric mosquito swatter:
Avoid using in humid environment, so as not to affect its high pressure effect.
Keep the electric mosquito bat dry to avoid short circuit or damage caused by moisture.
Avoid using in flammable and explosive environments to prevent accidents.
Children should use under adult supervision to prevent accidental handling or risk of electric shock.
In short, with its high efficiency, safety and environmental protection characteristics, the electric mosquito has become an ideal choice for summer pest control.
