Friends who know the construction industry, I believe that they are not unfamiliar with seamless pipes and welded pipes, but there is a difference between seamless pipes and welded pipes, and their difference is the price. So, how do we distribute seamless pipes and welded pipes?
In fact, how to divide the seamless pipe and the welded pipe, just look at this one place.
Welded pipes are not seamless pipes, and many people do not know their understanding and differences. In fact, the distinction between the two is pretty easy. The following will teach you how to distinguish.
1. The main difference between seamless pipe and welded pipe is the forming process. Welded pipes, usually by bending a flat plate and then welding, can find the weld on it. Thicker diameters are usually spiral welds. The seamless pipe generally accumulates the molten precipitation through the annular slit, and then is formed by processing such as drawing, so there is no welding. This is the difference between lightly distinguishing them with the naked eye.
2. In terms of performance, especially in pressure capacity, seamless pipes are greatly improved compared with ordinary steel pipes, and are often used in high-pressure equipment. The welding part of the welded pipe is the weak link, and the welding quality is also the main factor affecting the overall performance. People who live in the north have generally had the experience of freezing in the water or heating pipes in winter, and the place of the explosion is usually the weld.
3. When it comes to seamless pipes, they are indispensable in many aspects of our lives, such as the following four common aspects in daily life:
1) Application in reinforced concrete. The use of stainless steel bars in the reinforced concrete structure is to increase the strength and resist the corrosion of the embedded steel bars by the harsh marine environment and chlorides formed in the concrete. Corrosion-resistant stainless steel concrete meets the requirements of strength, corrosion resistance and earthquake resistance on the bridge decks and bridges of many marine buildings, and the maintenance-free life can reach 120 years.
2) Application in decoration engineering. In addition to walls and columns, automatic retractable doors, rolling shutter doors, stair fences, balcony handrails, rain gutters, flagpoles, street poles, arcade frames, in residential kitchen toilet counters, sinks, brackets, etc., seamless The application of tubes is increasing day by day.
3) Application in water supply engineering. With the rapid development of the economy and the improvement of people's living standards, a large number of urban residences, public buildings and tourist facilities have been constructed, which has put forward updated requirements for the supply of domestic water and hot water, and the issue of water quality has attracted much attention. Galvanized steel pipes commonly used in water supply projects are easy to corrode, and the phenomenon of "red water" and "green water" occurs, the water quality is difficult to improve, the leakage is large, and the life is short. Plastic pipes, composite pipes and other pipes are not as good as stainless steel seamless pipes in terms of safety, reliability, sanitation, environmental protection, and economical durability. Engineering practice at home and abroad has proved that stainless steel seamless pipes are energy-saving and environmentally friendly in the water supply system with good comprehensive performance and can ensure the quality of water supply.
