Pipelines, when laying which such pipe pipes are used, can be performed both by the outer laying method and the method of internal. Stainless pipes are very in demand in the installation of heating systems, DOS and water supply.
Any stainless pipe is a very strong and persistent product that can demonstrate its best qualities when performing construction and repair work, as well as in medical, transport, chemical and other industries. Its main advantage is a guarantee of high corrosion resistance of the pipeline transporting any aggressive environment — water, gas, acid, etc. D. At the same time, stainless steel pipes can be used for both external and internal laying, since they can equally well tolerate any ambient temperature.
Stainless steel pipes are welded and seamless, as well as relevant. They can differ in the thickness of the walls, in the shape of the section (square, rectangle, oval), however, the most popular remains a seamless thick -walled stainless pipe. There are several brands of steels to the manufacture of such pipes, the choice of which depends on the features of the operation of the future pipeline and the nature of the transported environment.
CTLLAGES for the warehouse are used to equip directly shops and warehouse rooms. Shelves for the warehouse are collected without any bolts and make up huge warehouse systems that have a height of up to 4-6 meters with a measured load on a shelf from about 200 to 800 kg.
For example, AISI 304 steel is endowed with the greatest corrosion resistance, is distinguished by excellent mechanical qualities, resistant to chemical influences. The temperature range of its operation begins with -200 ° C and ends at the level of +600 ° C. AISI 316 brand steel is more suitable for pipelines functioning at the chemical industry enterprises, and AISI 409 stainlessly for large treatment facilities. Finally, AISI 439 is food heat -resistant steel, the operation temperature of which can reach +900 ° C. Such products are indispensable in the food industry, as well as when constructing chimneys.
An important criterion when choosing a stainless pipe will be a method of welding. In order to perform a stainless transition, today welding with high-frequency currents, welding with a tungsten electrode in inert gas (is considered the highest quality and reliable), as well as plasma, laser and electron-radial welding. All this significantly affects the features of the installation of the pipeline, and on the features of its operation. In addition, you should take into account the possibility of choosing the type of surface of a stainless pipe: it can be polished, mirror-polished and matte. This becomes especially important when installing an external pipeline, in particular, from an aesthetic point of view.
