Stainless steel pipe is an economical cross-section steel and an important product in the steel industry. It can be widely used in life decoration and industry. Many people in the market use it to make stair handrails, window guards, railings, furniture, etc. There are two common materials, 201 and 304.
Accounting for about 8% to 16% of the total amount of steel, it is widely used in the national economy. Because the steel pipe has a hollow section, it is most suitable for the transportation of liquids, gases and solids; at the same time, compared with the round steel of the same weight, the steel pipe has a large section coefficient and a high bending and torsional strength, so it has also become a variety of mechanical and architectural structures. important material. Structures and components made of stainless steel tubing have a greater section modulus than solid components of equal weight.
Therefore, stainless steel pipe itself is a metal-saving economical section steel. It is an important part of high-efficiency steel, especially in oil drilling, smelting and transportation industries, followed by geological drilling, chemical industry, construction industry, and machinery industry, aircraft and automobile manufacturing, as well as boilers, medical equipment, furniture and bicycle manufacturing, etc. also require a large number of various steel pipes. With the development of new technologies such as atomic energy, rockets, missiles and aerospace industries, stainless steel pipes play an increasingly important role in national defense industry, science and technology and economic construction.
The thin wall of stainless steel pipe and the new reliable, simple and convenient connection method make it have more irreplaceable advantages of other pipe materials. There will be more and more applications in engineering, and the use will become more and more popular. The prospect is promising. Because stainless steel already possesses many ideal properties required by building materials, it can be said to be unique among metals, and its development continues. Existing types are constantly being improved to make stainless steel perform better in traditional applications, and new stainless steels are being developed to meet the stringent requirements of advanced architectural applications. Due to increasing production efficiency and quality improvements, stainless steel has become one of the most cost-effective materials of choice for architects.
Stainless steel will remain one of the best building materials in the world. With the implementation of the reform and opening policy, the national economy has grown rapidly, and a large number of urban residences, public buildings and tourist facilities have been built, which puts forward new requirements for hot water supply and domestic water supply. Especially water problems, people more and more valued, pleas also driving forward. Galvanized steel pipe, a commonly used pipe material, will gradually withdraw from the historical stage under the influence of relevant national policies due to its easy corrosion. Plastic pipes, composite pipes and copper pipes have become common pipe materials for piping systems. But in many cases, stainless steel pipes are more advantageous, especially thin-walled stainless steel pipes with a wall thickness of only 0.6-1.2mm are used in high-quality drinking water systems, hot water systems, and water supply systems that put safety and sanitation first. Safe and reliable, hygienic and environmentally friendly, economical and applicable. It has been proved by engineering practice at home and abroad that it is one of the new, energy-saving and environment-friendly pipes with the best comprehensive performance in the water supply system. comparable effect.
In the building water supply pipe system, since the glorious history of galvanized steel pipes has ended for a hundred years, various new plastic pipes and composite pipes have been developed rapidly. The needs of the system and the country's requirements for drinking water and related water quality. Therefore, relevant experts predict that building water supply pipes will eventually return to the era of metal pipes. According to foreign application experience, thin-walled stainless steel pipes are considered to be one of the pipes with the best comprehensive performance in metal pipes.
