Thick-walled stainless pipe
To paraphrase a famous line B. Mayakovsky, we can say: «I know the city will, I know, blossom garden, when such pipes in the Soviet country is!»
Advantages of stainless thick-walled pipe
Resistant to corrosion of structural stainless steels and 20H23N18 10H23N18 (analogue AISI 310S) different heat resistance. They can withstand heating up to 1500 ° C. The recommended operating range of 800 — 1100 ° C. Steel nonmagnetic and biologically inert. Welded by all known methods. The presence of: titanium, nickel, and chromium making highly durable tube without loss of plasticity and enables its use in contact with solutions of alkalis, acids and their salts with t ° to + 350 ° C.
Stainless steel alloys are known, are not cheap, and to produce tubes of these technologically difficult. However, such advantages as durability, minimal costs for repairs and maintenance, the possibility of recycling of scrap for remelting and subsequent use, makes pipe stainless steel highly profitable.
From the ratio of pipe outside diameter to wall thickness all round steel tube is divided into thin and thick. Thick-walled stainless steel tubes are produced in accordance with GOST 380−94. Besides stainless alloys
|Name||Relation to the external diameter of the tube thickness|
|Thick-walled stainless pipe||6 — 12.5|
|Especially thick-walled stainless pipe||less than 6|
The ratio of 6 means that the diameter of the tube 6 times the wall thickness. The ratio of 12.5 means that the pipe Ø 12.5 times the wall thickness. Size range is defined by the relevant industry standard. An important process step is the production of hardening, which imparts resistance tube to chemicals and high internal pressure, mechanical strength (torsional and kink) durability. Thick-walled stainless pipe can be either extruded (made: rolling, forging, drawing or molding) and electric welding. The weld, however was not carried out skillfully, does not preclude leakage. Therefore, for a variety of communications devices, that transport toxic liquid, often used stainless seamless pipe.
Pipes, thick-walled seamless steel corrosion maintain quality at t ° up to + 850 ° C. They are used in the petrochemical, machinery, equipment for high-temperature furnace, the transfer of corrosive liquids and hot gases — wherever critical corrosion resistance and heat resistance: For each corrosive environment chosen a specific type of stainless steel tubes. Such pipes are biologically inert, so use the food industry. Seamless thick-walled tubes are also used heat power engineering, construction, housing and communal services in oil and gas. Pipes especially thick-walled, most commonly used for drilling.
