  Since the British H. Brearly invented stainless steel sheet at the beginning of the last century, stainless steel sheet has combined the image of modern materials with its excellence in architectural applications. In addition to the excellent properties of steel, stainless steel sheet will not produce rust. Because stainless steel sheet has good corrosion resistance, it can permanently maintain the integrity of the engineering design of structural components. stainless steel sheet also combines mechanical strength and high extensibility. Easy to process and manufacture parts, plus its advantages such as long service life, recyclability and reuse, can meet the needs of architects and structural designers.

  1,How long does the most popular stainless steel sheet sheet last?

  304 stainless steel sheet is a kind of commodity. It is a commodity and has a certain life span. Now experts will answer you how long the service life of 304 stainless steel sheet plate is. For 304 stainless steel sheet plate, the ni element in its composition is very important, which directly determines the corrosion resistance and value of 304 stainless steel sheet plate.

  The most important elements in 304 stainless steel sheet plate are Ni and Cr, but they are not limited to these two elements. Specific requirements are stipulated by product standards. The common judgment in the industry is that as long as the Ni content is greater than 8% and the Cr content is greater than 18%, it can be considered as 304 stainless steel sheet. This is why the industry will call this type of stainless steel sheet 18/8 stainless steel sheet. In fact, the relevant product standards have very clear regulations on 304, and these product standards have some differences for different shapes of stainless steel sheet.

  According to my country's (National Gas Cooker Safety Management Regulations), it is clearly stipulated that artificial gas cookers will be scrapped after 6 years of use. Oil and natural gas stoves are scrapped after 8 years of use. The components have been severely aged and deformed when used beyond the limit, and there is no flameout protection device. It is easy to cause flashback, flameout, gas leakage, and cause various serious accidents. The above is our country's standard, and according to the international standard for the service life of common household appliances: the gas stove is 16 years (maybe foreign gas stoves and Chinese gas stoves have different manufacturing quality.

  2,What kind of conditions affect the service life of the stainless steel sheet sheet.

  The service life of stainless steel sheet bellows is very long, about 5-7 years in extreme environments, and up to 15 years in good environments. The main factors for the service life of stainless steel sheet bellows are the correct installation of the stainless steel sheet bellows, the control of the working environment, and the manufacturing process. 1. Correct selection and installation of stainless steel sheet bellows: Whether it is installed properly or not is directly related to the service life of the bellows. There are many products on the market. Make sure to use the same type of bellows and not mix them at will. 2. Use environment: Try to avoid long-term exposure and long-term direct exposure, which may cause deformation of the bellows and affect its life.

  As the name suggests, the advantage of the "thin-wall stainless steel sheet piping system" is that due to the excellent durability and corrosion resistance of stainless steel sheet, the service life of the water supply piping system in high-rise buildings will be longer and there will be less maintenance.

  Professor Kyosuke Sakaue of Meiji University is the leader of the Japan stainless steel sheet Association team. Both the International Nickel Institute and the Japan Valve Manufacturers Association are participants in the government-funded project, which mainly involves water supply and drainage pipes and fire-fighting facilities in collective housing.

  According to the report titled "The 200-year Lifespan of the Housing Concept", the average lifespan of Japanese apartment buildings is only 30 years, while the average lifespan of residential buildings in the United States is 55 years and that of the United Kingdom is 77 years. The short life span is an economic burden for residents and is not conducive to maintenance work. The report urged the housing industry to set an average life expectancy of 200 years for all dwellings as its goal. The future high-rise residential buildings should have the characteristics of energy saving, integration with the surrounding environment, earthquake resistance and easy maintenance.

  Most Japanese houses have multiple units, consisting of public and private spaces. The report recommends that the plumbing system in public areas should be regarded as part of the overall “framework” of the residential structure. This concept requires the installation of durable stainless steel sheet valves to reduce the need for repairs and extend the life of the entire piping system.

  Another benefit of long-lived houses is reduced carbon dioxide emissions. The disassembly or modification of the structure requires the production and transportation of pipes, valves and other materials, resulting in increased carbon dioxide emissions. Switch to a durable piping system and avoid constant replacement, which will inevitably reduce emissions and total energy consumption.

  These and other benefits show that Japan’s 200-year-life housing concept is consistent with the Japan stainless steel sheet Association’s goal of expanding the demand for stainless steel sheet products while promoting environmental sustainability.

  The working pressure of high-rise water supply system is generally greater than 0.6Mpa; higher pressure requirements for pipes. The working pressure of the plastic pipe used in the water supply system is less than this value, which is not competent; the expansion coefficient of the two materials of the composite pipe is very different, such as weak bonding or large temperature changes, it is easy to produce delamination; the maximum pressure of the thin-walled copper pipe can reach 5.9 Mpa; The thin-walled stainless steel sheet pipe can withstand high water supply pressure due to its excellent mechanical properties, up to 10Mpa, and is especially suitable for high-rise water supply.

  In fact, many world-renowned high-rise buildings use stainless steel sheet main water supply pipelines. For example, the communications tower in Kuala Lumpur, Malaysia, is the fourth tallest communications tower in the world. It uses 304 stainless steel sheet pipes and high-pressure Victaulic connectors to supply water to a 421-meter building; the Taipei Financial Center, which was built in 2004, is 508 meters high and will be the tallest building in the world. , Its water supply pipeline includes the main pipeline is a stainless steel sheet pipeline with a diameter of 318 meters and a Victaulic joint.
