Matte stainless pipes after rolling do not undergo additional processing — grinding, satin — and therefore the cost price of their manufacture is lower. As a result, the final surface of the products does not have a mirror shine, although for the rest of the indicators, in particular, for durability and operational efficiency, it is not inferior to similar products that have been glossed. Since the matte surface is more rough, it is better to keep powder paints, which is used if necessary to improve the decorative matt pipes.
Urgency of application
It is caused by increased performance indicators of matt stainless pipes, for the production of which, domestic stainless steels are used in accordance with GOST 1490−81, GOST 1491−81 and stainless steels of foreign manufacture of AISI 309L, 316L, 317L, 409, 410S, 420, 431 grades and so on. Advantages of matt stainless steels are: high resistance to all types of corrosion, mechanical strength (including — and high-temperature), increased wear resistance, resistance to adverse weather and climatic effects.
Domestic standards provide for the production of matt tubes from the following grades of stainless steels: 08ХН28МДТ, 12Х18Н10Т, 12Х18Н10Т, 12Х18Н12Т, 08Х19Н10Т, 10Х23Н18, 10Х17Н13М2Т, 04Х18Н10, 12Х17, 08Х13, 08Х22Н6Т, 15Х25Т, 2Х13. The chemical composition of the matt tubes is regulated by the national standard GOST 5632−2014, and the pipes of the imported production are ASTM A554, A312, A249, A269 and A270.
Physical and mechanical properties
Taking into account the mandatory heat treatment of stainless steel pipes, their mechanical characteristics are determined by the data given in the table:
|steel grade||The limit of time resistance, MPa,||Relative elongation at tension,%||Density, kg / m 3|
|not less than|
It is allowed to manufacture matt tubes with micro additives of rare earth metals. The sulfur content in the steel for matt pipes to be welded (as indicated in the order) should not exceed 0.02%.
Scope and range
Matte pipes made of stainless steel are used in cases that do not require special decorative qualities. For example, for the installation of underground water supply and sewerage networks, gas mains, central heating units. In the industry, matte pipes made of stainless steels are used as supporting stands of production equipment, as elements of trestles for the reception of liquid corrosive media, heat exchangers, etc.
The assortment is most often ordered matt tubes from stainless steels 20x10mm — 100x50mm, 10x10mm-100x100mm, 9.53−101.6mm and more (under special orders). Thickness 0.3 mm — 3.0 mm, length — 6 m or on request of customers.
Supplier — AvekGlob Company — offers to purchase matt tubes from stainless steels at a price formed on the basis of European and world standards of production. Buy these products can be wholesale and retail. For regular customers, there is a flexible system of discounts.
