Hexagonal steel pipe is also called special-shaped steel pipe, including octagonal pipe, rhombic pipe, elliptical pipe and other shapes. Hexagonal steel pipe is an economic section steel pipe, including non-circular cross-section outline, equal wall thickness, variable wall thickness, along the length direction, variable diameter and wall thickness, cross-section symmetry and asymmetry. Such as square, rectangle, cone, trapezoid, spiral, etc. Special-shaped steel pipe can better adapt to the particularity of service conditions, save metal and improve labor productivity of parts manufacturing. Hexagonal steel pipes are widely used in aviation, automobile, shipbuilding, mining machinery, agricultural machinery, construction, textile and boiler manufacturing. Cold drawing, welding, extrusion and hot rolling are the main methods to produce special-shaped pipes, among which cold drawing is widely used.

304 304L Pipe is the most common Stainless Steel Pipe,Grade 304 / 304L stainless steel has a minimum of 18% chromium and 8% nickel. The only difference between them is the carbon content. Type 304 has a maximum carbon of 0.07% .Type 304L has maximum carbon of 0.030 %. 

As a factory,we can provide 304 304L Hexagon 304 304L Hexagon Ss Pipe and other Polygon Stainless Steel Pipe. If you are finding a kind of Stainless Steel Pipe For Construction, 304 304L is an ideal option to you.
