Relevance

Steel seamless pipes are manufactured by rolling, pressing or drawing. Nowadays, they are popular. The most-requested type is a pipe of grade X12CrNiTi18−10. What is the secret of being so popular? The thing is that no matter how skilfully and sophisticated a welding seam was executed, it is impossible to avoid its leaking. And if in such pipelines circulates a toxic liquid, a probable efflux must be prevented.

Advantages

There are a lot of advantages of seamless tubes: reliability, long operational life, multipurposeness, aesthetic quality, high anticorrossive and protective properties. Seamless pipe are an absolute guarantee of undesired leaking in common communications (heating, water supply), and aggressive liquids at factories. Application of stainless thin-walled and thick-walled pipe allows varying between specific quantity of metal and weight of structure. Thin-walled stainless tube gives lightness to structure. It is much-requested in furniture trade.

Demerits

The only demerit of such tubes is its high self-cost. But taking into account their reliability and long operational life, such price is more than warranted.

Application of different pipe types

Stainless pipe X3NiCrCuMoTi27−23

Seamless stainless pipe X3NiCrCuMoTi27−23 is indispensable in manufacture of industrial equipment and welding constructions that operate in boiling sulfuric acid of any concentration (except for 55%), in acetic or phosphorus acids. Pipe is indented to operate for a long time in petroleum chemistry and paper-and-pulp industry.

Stainless pipe X12CrNi25−20

Heat-resistant pipe of this grade is manufactured out of high-alloyed steel of austenitic type. It is used in manufacture of fixtures, combustion well parts, bridges and other elements for attachment of fittings and boilers that work at a temperature of not more than 1100 °C.

Stainless pipe X10CrNiMoTi18−12

Stainless pipe of this grade is resistant to effect of acids and is manufactured out of austenitic steel. It is alloyed with chrome, molybdenum, titanium, nickel. A demand for this grade constitutes about 70% of extent of all manufactured stainless steels. Each of the alloying components in steel composition increases some defined characteristics: nickel — corrosion resistance and plasticity; molybdenum and chrome — corrosion resistance and heat resistance; titanium — strength and wearing quality at a high temperature. Such pipes are easily welded without previous heating and finishing thermal processing of seam. They are widely applied in medicine, chemical, and food industry due to resistance to destructive aggressive environments. The pipe can keep all properties for a long time up to a temperature of 600 °C. In comparison to other pipes, it has longer operational life and does not require additional expenses for renewal and repair. Welding constructions are made of seamless stainless pipe of such type.

Stainless pipe X12CrNiTi18−10

Pipes of grade X12CrNiTi18−10 are the most popular in their market segment. This is proved by advertising catalogues of a large number of world companies that focus on distribution of metal-roll. The letters in name mean a content of chrome, nickel, titanium in composition. Such pipe can have welded seam or to be seamless. You have to choose pipe relating to application sphere of products. X12CrNiTi18−10 grade relates to steels of austenitic group. It is optimized for a long operational use in gaseous and liquid aggressive environments: in metallurgy, petroleum chemistry, chemical industry, shipbuilding. The following goods are manufactured out of seamless stainless pipes: muffles, heat exchangers, parts for metallurgic furnaces, spark points for fuse lighters.

X12CrNi25−21

All industries of transportation, food, chemical manufacture require a perfect corrosion resistance of pipelines. So that, they need pipes made of X12CrNi25−21 grade. Such tube is often used for laying of hot and cold water-supply systems as long as it does not influence on a quality of water. They are also broadly utilized for different construction, pipelines, and boilers. The main appropriation of stainless pipe X12CrNi25−21 is jointing of pipeline parts and regulating of flows of various environments. The tube is optimized for a long operational use in composition of building constructions, petroleum chemistry, metallurgic industry — in all spheres where are needed a corrosion and heat resistance (including aggressive environments). The following goods can be made out of stainless seamless pipe X12CrNi25−21: forgings, bandages that work up to a temperature of 660−700°С, details of combustion wells and other furnace equipment optimized for heat stresses at a temperature higher than 1000 °C.
