Nowadays, more and more people begin to use stainless steel water pipes as water supply pipes, especially in construction projects, hospitals, schools, villas and other places that need water supply. Compared with water pipes of other materials, stainless steel water pipes have more excellent performance, such as environmental protection, health, safety, long service life, high pressure resistance, and corrosion resistance.
Water is related to human life safety and health. It is important to use plumbing that ensures safe water quality. So, when we choose water pipes, we must choose stainless steel water pipes. We must keep our eyes open and carefully detect and screen from every aspect. So, how to choose a satisfactory stainless steel water pipe? Next, we briefly analyze the method.
1. See if the material is qualified
The quality of stainless steel water pipes depends on the quality of the raw materials. 316 stainless steel has similar functions to 304 stainless steel. 304 stainless steel water pipe has excellent corrosion resistance in dry and clean environments. 316 stainless steel water pipe has better corrosion resistance than 304 stainless steel water pipe in marine and industrial applications. 316L stainless steel has a lower carbon content than 316 stainless steel. Therefore, 316L stainless steel water pipe has better corrosion resistance. If you build a water supply piping system by the sea, you can choose 316 or 316L stainless steel water pipes. However, 316L stainless steel is more expensive than 316 stainless steel and 304 stainless steel. For buildings in non-waterfront areas, lower-priced 304 stainless steel water pipes can be selected.
2. See if the thickness meets the standard
The wall thickness of the stainless steel water pipe is the key to determining its connection strength. When the wall thickness is reduced below the safety factor, the reliability will inevitably decrease by several notches. In fact, the wall thickness is only a surface requirement. The quality of stainless steel water pipes is not only reflected in the connection strength, but also in the seismic performance in various environments, the impact performance under various external forces, and the service life and erosion allowance of products in concealed engineering. At present, the national standard thickness of domestic stainless steel water pipes is 0.8-2mm, which is lower than the nominal diameter (DN). From the point of view of safety factor and economy, DN15-DN recommends G100 stainless steel water pipe B/T19228.2 specification and GB/T19228.2-2011. We think this is the best option for stainless steel water pipes.
3. See if the manufacturing process is professional
The quality of stainless steel water pipes also depends on the manufacturer's manufacturing process, as well as the details of the production process. For example, the smoothness of the inner wall, the smoothness of the weld, the color of the weld and its surroundings, the wall thickness of the water pipe, and the presence or absence of burrs are all manifestations of the level of manufacturing technology.
4. See if the manufacturer has qualified qualifications
Regardless of the industry, when selecting products, we must give priority to qualified manufacturers in order to purchase qualified products.
Manufacturers of stainless steel water pipes and fittings must have product quality certificates and quality inspection reports for related materials. The raw material, specification, production batch and manufacturer's name of stainless steel water pipes and fittings should be clearly marked on the packaging. The brand reputation of the manufacturer is very important.
5. See if the price is reasonable
Many consumers pay more attention to product quality, manufacturer and selling business preference when choosing a product. We all need to compare product quality, manufacturers and product prices. After comprehensive consideration, we can buy better products through reasonable choices.
