Stainless steel decorative pipe, also known as stainless steel welded steel pipe, abbreviated as welded pipe, is a steel pipe made by welding steel or steel strip after being curled and formed by a machine and a mold. The production process of welded steel pipes is simple, the production efficiency is high, there are many varieties and specifications, and the equipment resources are limited, but the strength is generally lower than that of seamless steel pipes.

Welded steel pipe, abbreviated as welded pipe, is a stainless steel pipe made by welding steel plates or steel strips after being curled and formed by a machine and a mold.

2. Characteristics of welded steel pipes:

From the above process flow, it is not difficult to see that: firstly, the product is produced continuously online, and the thicker the wall thickness, the greater the investment in the unit and welding equipment, making it less economical and practical. The thinner the wall thickness, the lower its input-output ratio will be; Secondly, the process of the product determines its advantages and disadvantages. Generally, welded steel pipes have high precision, uniform wall thickness, high internal and external surface brightness of stainless steel fittings (determined by the surface grade of the steel plate), and can be customized to any length. Therefore, it demonstrates its economy and aesthetics in high-precision, medium low pressure fluid applications.

There are chloride ions present in the usage environment. Chloride ions are widely present, such as salt, sweat stains, seawater, sea breeze, soil, and so on. Stainless steel corrodes rapidly in the presence of chloride ions, even surpassing ordinary low-carbon steel. So there are requirements for the use environment of stainless steel, and it needs to be regularly wiped to remove dust and maintain cleanliness and dryness.
