Stainless steel pipe 12x18n10t, steel 08x18n10t according to GOST 9941-81: prices and characteristics

Stainless steel pipes and their characteristics

Compared to conventional seamless ferrous metal pipes, stainless steel pipes do not have a welded seam, and therefore have a higher safety margin. It is no secret that no matter how well the seam is made, it cannot boast of 100% tightness; on the contrary, it is the most vulnerable point in the body of the pipe. Often it is the seam connection that causes accidents. The most popular today are stainless steel pipes, which are highly resistant to various influences.

Since GOST 9941 pipes carry liquids harmful to human health, accidents in this case are critical. In this case, pipes made of steel 08x18n10t are best suited. Since they have high reliability and corrosion resistance. This type of pipe can withstand very high loads, in particular gas or liquid pressure from the inside and soil or water pressure from the outside. For the production of stainless pipes, high quality carbon and alloy steels are used. The 12x18n10t marking on the product indicates that the steel contains nickel, manganese and chromium. It is thanks to the alloy of chromium and iron that it was possible to achieve those damaging properties that stainless steel pipes currently possess. Also, the distinctive properties of this type of pipe are: reliability, versatility, aesthetics, resistance to corrosion, and, importantly, durability. Since laying main pipelines is a very difficult task, the installed pipeline systems must be durable.

A pipe made of steel 12x18n10t can rightfully be called the most durable, reliable, durable and, moreover, very aesthetic. Excellent anti-corrosion properties make it very relevant when installing water supply systems, because, as you know, it is the pipe seam that is primarily susceptible to corrosion.

In fact, the only significant drawback of such pipes is their high cost. However, taking into account all the above advantages, this disadvantage is fully justified.

Application of stainless pipes

Currently, about 70% of the total number of products made from stainless steel are seamless pipes. Any type of welding can be used for them, since in this case there is no need for more thorough heating of the seam itself.

Such pipes are widely used in production, energy, transport, chemical, food industries, and even in medicine there is a place for the use of this product. Seamless stainless steel pipes occupy a special place in construction. They are used in the installation of plumbing systems, both inside and outside the building, as well as heating systems and hot water supply.

Over time, such pipes do not lose their original qualities even after prolonged use in “harsh” conditions and are absolutely resistant to high temperatures (up to 600 degrees). It is also important to note that stainless steel does not affect water quality.

You can buy a stainless pipe from the TRUBPROM company in the Pipe Shop section.

Seamless stainless steel pipe 12x18n10t (AISI 321

Round stainless steel seamless pipe (solid drawn) 12x18n10t (AISI 321) is a titanium-alloyed austenitic-chromium-nickel steel pipe, made from a solid stainless steel billet 12x18n10t, by piercing the middle on a press-stitching mill.

The imported analogue of the 12x18n10t pipe is the AISI 321 pipe. In terms of assortment, the 12x18n10t stainless steel pipes comply with GOST 9941-81 (seamless cold-deformed seamless drawn) and GOST 9940-81 (hot-deformed pipes made of corrosion-resistant steel for general purpose). The diameters of the former vary from 5 to 273 mm, and the wall thickness - from 0.2 to 22 mm. Seamless stainless steel pipe - GOST 9940-81 has a diameter from 57 to 325 mm and a wall thickness of 3.5-32 mm. The chemical composition of pipe steel 12x18n10t corresponds to GOST 5632-72.

On the market you can find stainless steel seamless pipe 08x18n10t (maximum 0.8% carbon), which differs from pipe 12x18n10t (maximum 0.12%) mainly in carbon content, so their properties are quite similar.

IMPORTANT: Lira-Metal LLC is a warehouse company. We sell all rolled metal products from a warehouse in Moscow! This is what rolled metal looks like in our warehouse:

I am pleased to offer you stainless steel seamless pipes 12x18n10t of the following types:

Extra-thin-walled: 1) Extra-thin-walled stainless steel pipe (GOST 10498-82) with a wall thickness from 0.2 mm (for the smallest in diameter) to 1 mm (for the largest in diameter). The surface of such pipes is etched; upon customer request, the internal and external surfaces can be additionally processed (grinding, polishing the pipe).

Thin-walled: 2) Thin-walled seamless stainless steel pipe (GOST 9941-81). When dividing its diameter by the wall, the resulting value must be at least 40.

Thick-walled: 3) Thick-walled seamless stainless steel pipe (GOST 9941-81 and GOST 9940-81). When dividing its diameter by the wall, the resulting value should be from 6 to 12.5.

Extra-thick-walled: 4) Extra-thick-walled stainless steel pipe (GOST 9941-81 and GOST 9940-81). When dividing its diameter by the wall, the resulting value will be less than 6.

Pipe 12x18n10t has high corrosion resistance, due to which it is used in many industries. For example, in the production of nitric acid, nitrogen salts, thermal phosphoric acid, most organic products, in the food industry, in the chemical-pharmaceutical industry (production of phthalazole, pyramidone and other medicines) and in the production of medical instruments.

The client can always buy stainless steel seamless pipe 12x18n10t (AISI 321) at reasonable prices, wholesale and retail. The price of stainless steel pipes 12x18n10t (AISI 321) depends on the manufacturer and technological characteristics.
