Which pipes are suitable for water pipes

Special requirements are placed on the laying of drinking water pipes. Pipes through which drinking water flows must not oxidize and thus affect its composition. Today the most convenient and common material for pipes is stainless steel, which has corrosion-resistant properties. Chromium-containing stainless steel and galvanized stainless steel are ideal for drinking water pipes. These pipes do not oxidize, do not rust, and do not change the composition of the water. Alloy of iron with carbon - carbon steel is usually galvanized. Also use steel alloyed with various additives. On the surface of chrome-containing stainless steel is an oxide film that forms when it interacts with the air. It and protects the metal from further oxidation.

Advantages of stainless steel pipes

Stainless steel pipes meet the most stringent hygiene requirements. Stainless steel is chemically passive at Ph from 4 to 10, with allowable Ph from 6.5 to 9.5. Such pipes are very reliable and notable for their durability, withstanding considerable pressure and temperature variations.

Disadvantages

After 8-10 years of operation, the pipes, as they are called, begin to tighten from the inside and pass less water flow. This usually happens with cold water pipes, because hot water contains special additives that do not allow the pipes to "shrink". Chlorine has an adverse effect on stainless steel, which kills pathogens and pathogens in the water, disinfects the water. Of course, chlorine ions have an adverse effect on stainless steel pipes, but it is impossible to refuse it yet.

Production

Stainless steel pipes are made in two ways.-welded and seamless. Each method has its own advantages. Seamless pipes are more durable, but also more labor-intensive to produce. When pipes are welded, the stainless steel sheet is rolled up in such a way that the seam runs the entire length of the pipe. Welding can take place in a spiral - along the coiled steel strip. In this case, the strength of the seam is only 10% lower than the strength of the whole sheet.
