The benefits of thick-walled stainless pipe

Stainless steel structural steel grades 10Х23Н18 and 20H23N18 (AISI 310S) are a class of heat-resistant alloys and have high corrosion resistance. Operating temperature range — from 800 до1100°C. This steel is biologically inert, non-magnetic. Welding is carried out in any species. Content consisting of titanium, chromium, Nickel, gives the pipes a particular strength without loss of ductility and allows the use in contact with solutions of acids, alkalies, their salts at temperatures up to +350°C.

The cost of stainless steel alloys rather big, and produce one pipe is not technologically simple. But such qualities as durability, low maintenance costs, repairs, and also the possibility of disposing of their scrap for later melting and further use, makes thick-walled stainless steel pipes highly profitable.


The ratio of outside diameter to wall thickness of round pipe are divided into thick-walled and thin-walled. Heavy wall is manufactured according to GOST 380−94. Size limits are set to the industry standard. An important technological stage in the manufacture of pipes — tempering gives the material high resistance to chemical. reagents and high operating pressure, durability and mechanical strength (fracture and twisting). Such a tube is seamless (made by rolling, forging, drawing or extrusion), as well as electric. On even the highest quality suture cannot exclude the leak. Therefore, to transport the toxic liquids used is seamless pipe.


Thick-walled seamless steel pipe at a temperature of 850 °C is able to maintain the anti-corrosion quality. They are used in mechanical engineering, petrochemistry, for manufacture of furnace high temperature equipment, for the transportation of fuel, hot gases and toxic liquids — wherever you need heat resistance, corrosion resistance. For each of the aggressive environments select the specific type of stainless pipe. For example, biological inertness are important in the food industry. Thick-walled seamless tubes are also used in construction, power, utilities, gas, oil, and shipbuilding. Particularly thick-walled tube, usually used for carrying out drilling operations.
