What is the future of stainless steel pipes? How big is the market?

With the rapid development of national economy and the construction of a large number of townhouses, public buildings and tourist facilities, people have put forward new requirements for hot water supply and domestic water supply, and pay more and more attention to water quality, so the requirements for pipelines are also increasingly high. From galvanized steel pipe - plastic pipe (PP-R) - composite pipe - then copper pipe, to stainless steel pipe, which is currently being heavily promoted, are constantly being updated and upgraded. Therefore, the stainless steel tubes produced by Zhejiang Bewell Steel Co., Ltd. sell well in the home improvement market.

Japan
Since 1982, when the Japan Water Works Association established the standards "JWWA G 115 - Stainless steel pipes for water supply" and "JWWA G 116 - Stainless steel pipe joints for water supply", the prevalence of stainless steel water supply pipes has reached almost 100%. Stainless steel piping systems are effectively resistant to earthquakes and greatly reduce leakage rates.
United States
The US government's National Standard/National Sanitation Fund International Standard ANSI/NSF 61-1997a, developed under the 1996 Clean Water Act, clearly states that "Only stainless steel and ductile iron pipe are permitted for metal piping used for drinking water."
Germany
Since 1980, Germany has been using a large number of stainless steel materials in its water systems. Mapress Germany is the largest manufacturer of pipe fittings in Europe and according to previous sales figures, stainless steel fittings account for 51% of its pipe fittings sales.
Sweden
Karls Koga in Sweden is after 10 years of trials, ductile iron and PVC buried water mains have been replaced with 316 stainless steel pipes.

United Kingdom
Scottish hospitals used copper water pipes in the past, but the soft water quality led to corrosion and failure of the copper pipes, which were later all replaced with stainless steel pipes and fittings. A review of usage years later showed no signs of corrosion.

In 1978, China's steel pipe production was only 1,687,000 tons, reaching 98.27 million tons in 2015. Since the reform and opening up, the cumulative production of steel pipes in China has exceeded 1 billion tonnes, including more than 650 million tonnes of welded pipes.In 2018, the output of plastic products in China was 60,421,500 tonnes, including about 17.6 million tonnes of plastic pipes.
According to the report, from February 2020 to January 2021, the number of water supply and drainage projects in the country is as many as 2.8w, with the total project amounting to 1.8 trillion.
In accordance with the carbon steel and plastic pipe total annual production of nearly 100 million tons of 10% rough projection, China has about 10 million tons of stainless steel water pipe market each year. If the average according to the minimum 50,000 yuan / ton (the current comprehensive average price of water pipes and fittings is roughly 100,000 yuan / ton), plus the distribution links, installation and construction costs, it is possible to achieve at least a trillion yuan per year in total output value.
China's steel and plastic pipe market stock of at least 1/10 need to be replaced by stainless steel water pipes, stainless steel water pipe market potential stock demand of more than 100 million tons, the direct output value and derivative value is even greater.
From the 2020 government work report to see the development trend of stainless steel water pipes in 2021, the country's water supply, old reform and other aspects of policy and stainless steel pipe industry is closely related. Various enterprises have joined the stainless steel water pipe industry, according to industry associations statistics as of October 2020, the number of stainless steel water pipes and fittings enterprises in China rose to 231. The original plastic pipes, cast iron pipes to manufacturers have ventured into the production of stainless steel pipes, a share of the billion dollar market.
Zhejiang Bewell® Steel Industry Co.,Ltd. specializes in the production of stainless steel pipe, the company has 600x600 large cross-section square pipe, cold-formed steel unit roll bending, roll extrusion forming production lines, bending, straightening, cutting and polishing equipment, annual production capacity of 50,000-80,000 tons.Since its inception, the company has been adhering to the business philosophy of "integrity and cooperation, common development", after persistent development, become the leader in the steel industry.
