Thick-walled stainless steel pipe

Stainless structural steel grades 10Х23Н18 and 20Х23Н18 (AISI 310S) belong to the class of heat-resistant alloys and are highly corrosion resistant. The working temperature range is from 800 to 1100 °C. This steel is biologically inert and non-magnetic. Welding is carried out by any types. The content in the composition of titanium, chromium, nickel, gives the tubes a special strength without loss of plasticity and allows the use in contact with solutions of acids, alkalis, their salts at temperatures up to +350 ° C.

The cost of stainless alloys is not insignificant and it is not technologically simple to produce pipes from them. But such qualities as durability, minimum maintenance and repair costs, as well as the possibility of recycling their scrap for subsequent remelting and further use make stainless thick-walled tubes highly profitable.

Manufacturing

Round tubes are divided into thick-walled and thin-walled according to the ratio of outer diameter to wall thickness. Thick-walled stainless steel pipe is manufactured in accordance with GOST 380-94. Marginal sizes are determined by industry standard. The important technological stage in tubes manufacturing, i.e. hardening, gives the material high resistance to chemical reagents and high operating pressure, durability and mechanical strength (at fracture and twisting). Such pipe is solid drawn (made by rolling, forging, drawing or extrusion), as well as electrically welded. Even the highest quality weld can not prevent leakage. That is why seamless pipes are used for transporting toxic liquids.

Application

Thick-walled stainless steel pipe at temperatures up to 850 °C is able to maintain resistance to corrosion. It is used in mechanical engineering, petrochemistry, for the production of furnace high-temperature equipment, transportation of fuel, hot gases and toxic liquids - everywhere where heat resistance and corrosion resistance is required. In each case, a specific type of stainless steel alloy is selected. For example, biological inertness is important in the food industry. Thick-walled seamless pipes are also used in construction, shipbuilding, heat and power engineering, gas and oil production. Particularly thick-walled pipes are indispensable for drilling work.
