To paraphrase the famous lines of V. V. Mayakovsky, we can say: "I know, the city will be, I know, the garden will bloom, when there are such pipes in the Soviet country!

Advantages of thick-walled stainless steel pipe

Corrosion-resistant structural stainless steel 20X23H18 and 10X23H18 (analogue of AISI 310S) are heat-resistant. They withstand heat up to 1500 °C. Recommended operating range is 800 - 1100 °C. The steel is non-magnetic and biologically inert. It can be welded by all known welding methods. The presence in the composition: titanium, nickel and chromium makes the pipe particularly strong without loss of plasticity and allows to use it in contact with alkaline solutions, acids and salts at t ° to +350 ° C.

Disadvantages

Stainless alloys are notoriously expensive, and to make a pipe from them technologically difficult. However, such advantages as durability, minimum repair and maintenance costs, the possibility of recycling scrap for remelting and subsequent use, makes stainless steel pipes highly profitable.

Manufacturing

According to the ratio of pipe outer diameter to wall thickness, all round steel pipes are divided into thin- and thick-walled. Thick-walled stainless tubes are produced in accordance with State Standard 380-94. Except for stainless steel alloys.

Name Relation of outside diameter of a tube to thickness
Thick-walled stainless tube 6 - 12,5
Stainless steel pipe especially thick-walled less than 6

A ratio of 6 means that the pipe diameter is 6 times the wall thickness. A ratio of 12.5 means that the pipe diameter is 12.5 times the wall thickness. The size range is specified by the relevant industry standard. An important technological stage in production is hardening, which gives the pipe resistance to chemical reagents and high internal pressure, mechanical strength (for twisting and breaking) and durability. Thick-walled stainless steel pipe may be solid drawn (made by rolling, forging, drawing or pressing) and electro-welded. Welded seam, no matter how skillfully executed, does not rule out leaks. Therefore, for the device of various communications, which transport toxic liquids, more often used stainless steel pipe seamless.

Use

Seamless thick-walled steel pipes retain anticorrosive qualities at t° up to +850 ° C. They are used in petrochemistry, mechanical engineering, for high-temperature furnace equipment, in the transfer of aggressive liquids and red-hot gases - everywhere where corrosion resistance and heat resistance are important: For each aggressive environment is selected a specific type of stainless steel pipe. Such pipes are biologically inert, so they are used by the food industry. Seamless thick-walled pipes are also used in heating, construction, housing and utilities sector, oil and gas production. Particularly thick-walled pipes are mostly used for drilling work.
