Profile pipes http://metallobaza.biz/price/metalloprokat-i-truby/truby-profilnye - products of the modern metal rolling industry. Such pipes are used in the construction and architectural design industry: they make frames, supports, spans and floors of various structures from them, they are used to repair and install various structures - from advertising billboards to interfloor floors in buildings.
Features of shaped pipes
Profile pipes differ from simple round pipes in shape: they can be rectangular, square and even oval.
The practical difference is that such pipes are almost not deformed by deflection, due to the available stiffeners. It is convenient to lay them on flat surfaces and can withstand significant loads, which is important in construction. The installation of such pipes is facilitated by the use of special welding wire. The mass of the shaped pipes is small, they do not make the structure under construction heavier.
How are shaped pipes made?
A blank for the manufacture of a standard shaped pipe is a familiar round longitudinal seam pipe, which is bent and welded from the initial element, the "strip". After that, the round pipe of the calculated cross-section is sent for molding - it is deformed using cold or hot technology, using rolls - so as to obtain the intended cross-sectional shape. The next stage of work on the pipe is to control the strength of the weld, and then heat treatment.
The most common metal from which this type of pipe is made is steel, but there are other options.
