304 seamless pipe wall thickness standards and allowable deviation dimensions

If I want to install 304 stainless steel water pipes in my home, what wall thickness should I buy?
When purchasing stainless steel water pipes, many customers think that the thickness of the water pipe determines the quality of the pipe. The thicker the wall thickness of the stainless steel pipe, the higher the quality of the water pipe. Is this view appropriate? In fact, this type of Understanding is a misconception, and the quality of stainless steel water pipes cannot be judged by sense alone. Increasing the understanding of stainless steel pipes is the best way to identify the quality of pipes. At present, stainless steel water supply pipes are all thin-walled. Stainless steel water pipes have high tensile strength, are corrosion-resistant, and have no harmful substances to precipitate for long-term use. The inner walls are smooth and clean, and they are not prone to scale. They are sanitary-grade water pipes.
304 seamless pipe wall thickness standards and allowable deviations (Figure 1) Many people who buy stainless steel pipes think that the thicker the wall thickness, the better. In fact, it is unnecessary. If the wall thickness is too thick, then the inner diameter of the pipe will It will be narrower and the water output will be smaller. If you want the inner diameter of the pipe to be larger, you need to purchase stainless steel water pipes with larger specifications. In this way, the cost of the pipe will increase. At this stage, there are two series of thin-walled stainless steel water pipes produced by domestic manufacturers, which are divided into GB 1 series and GB 2 series. Under the same nominal diameter (DN), the outer diameter and wall thickness of these two thin-walled stainless steel water pipes may vary. will vary. Traditional connection methods such as welding and flanges can only use thick stainless steel pipes due to the characteristics of their installation processes. In order to ensure the connection strength and welding reliability of the pipeline, the wall thickness of the stainless steel pipe is generally required to be above 2.0 mm. At present, the most commonly used in the home decoration market is double-pressure stainless steel water pipes. The pressure resistance is generally between 1.6MPa and 2.5MPa. The diameter of the pipes used in self-built houses or large villas may be larger, so most home decoration uses DN15~DN50. Within, the normal thickness is 0.8mm~1.2mm. In the case of ordinary household and commercial housing renovation, a wall thickness of 0.8mm is basically sufficient.

As well as the service life and corrosion resistance of pipelines in concealed projects. The above is the relevant knowledge about thin-walled stainless steel water pipes. If you are normally considering choosing pipes for decoration and are not sure what wall thickness you should choose for 304 stainless steel water pipes for home decoration, you can also consult the customer service of the stainless steel water pipe manufacturer! All in all, when purchasing stainless steel water pipes, you should choose well-known brands and manufacturers with good user reviews to ensure product quality and safety.
Dimensions and allowable deviations of national standard seamless steel pipes
Dimensions and allowable deviations: Deviation level D1: allowable deviation of standardized outer diameter ±1.5%, minimum ±0.75 mm Deviation level D2: allowable deviation of standardized outer diameter ±1.0%. Minimum ±0.50 mm Deviation level D3: Standardized outer diameter allowable deviation ±0.75%. Minimum ±0.30 mm Deviation level D4: Allowable deviation of standardized outer diameter ±0.50%. Minimum ±0.10 mm 2. National standard seamless steel pipes are made from steel ingots or solid tube blanks that are perforated into capillary tubes, and then hot-rolled, cold-rolled or cold-drawn. 3. National standard seamless steel pipes are made from steel ingots or solid tube blanks that are perforated into capillary tubes, and then hot-rolled, cold-rolled or cold-drawn. National standard steel pipes play an important role in my country's steel pipe industry. According to incomplete statistics, there are more than 240 national standard steel pipe manufacturers in my country, more than 250 seamless steel pipe units, and an annual production capacity of about 4.5 million tons. 4. Classification: Seamless steel pipes are divided into two categories: hot-rolled and cold-rolled (dial) seamless steel pipes. (1) Hot-rolled seamless steel pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes. (2) Cold-rolled (rolled) seamless steel pipes are divided into general steel pipes
