Hexagonal steel is a kind of section steel, also known as hexagonal bar, bar with regular hexagonal section. The nominal size is the opposite side length S. Hexagonal steel can be used to form various stress components according to the different needs of the structure, and it can also be used as a connection between components. It is widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouse shelves.
Special-shaped pipes are generally distinguished according to the broken section and overall shape. They can be generally divided into elliptical special-shaped pipes, triangular special-shaped pipes, hexagonal special-shaped pipes and so on. Diamond shaped pipe, stainless steel pattern pipe, stainless steel U-shaped pipe, D-shaped pipe, stainless steel elbow, S-shaped pipe elbow, octagonal shaped pipe, semi-circular shaped steel circle. Hexagonal shaped steel pipe with unequal edges, plum blossom shaped steel pipe with five petals, double convex shaped steel pipe, double concave shaped steel, melon seed shaped steel pipe, conical shaped steel pipe, corrugated shaped steel pipe, etc.
Classification of hexagon steel tubing:
Classification of material used for hexagon steel pipe: 20, 45, 16 manganese and other different materials have different uses.
INTRODUCTION OF HEXAGONAL STEEL TUBE
Hexagonal steel tube is a kind of hexagonal (hexagonal) steel pipe which is made of steel. It is also called special-shaped steel pipe. Among them, there are octagonal, rhombic and elliptical tubes.
Hexagonal steel tube is the general name of steel pipe with other cross-section shapes besides circular pipe. It has welded special-shaped pipe and seamless special-shaped pipe. Because of the material relationship, stainless steel special-shaped pipe is generally more than 304 material, 200, 201 material hardness strong wind, it is more difficult to shape.
Hexagonal steel tube is widely used in various structural parts, tools and mechanical parts. Compared with circular pipe, stainless steel special-shaped pipe generally has larger inertia moment and section modulus, has greater flexural and torsional resistance, can greatly reduce the weight of the structure and save steel.
Hexagonal steel tubes are generally distinguished according to the broken section and the overall shape. They can be generally divided into elliptical, triangular, hexagonal and special-shaped pipes. Diamond shaped pipe, stainless steel pattern pipe, stainless steel U-shaped pipe, D-shaped pipe, stainless steel elbow, S-shaped pipe elbow, octagonal shaped pipe, semi-circular shaped steel circle. Hexagonal shaped steel pipe with unequal edges, plum blossom shaped steel pipe with five petals, double convex shaped steel pipe, double concave shaped steel, melon seed shaped steel pipe, conical shaped steel pipe, corrugated shaped steel pipe, etc.
Affected by China's economic slowdown, there is low demand for hexagon steel tube commodities. Clarkson Plc, the world's largest shipping consultancy, had forecast China's steel imports would rise 6% in 2016, down from 8.7% in 2015. The BDI decline partly reflects the risk of deflation in China, while industries such as shipping and steel will be hit hard. Learned from the Hangzhou market today, although the upstream raw materials in recent days rose a lot, factory price has also been raised, but the market volume is insufficient, the downstream has been insensitive to the price, and the majority of wait-and-see, traders are not optimistic about the market trend, there is no plan to adjust prices.
Market interpretation: perhaps the current BDI slump is just a prelude to the commodities, including the entire economic recession will bring iron ore into the abyss once again, Don't think that $40 or more is bad enough right now, with the giants doggedly ramping up production, Fu MaoGe drunkenly said don't worry that the hard days for hexagon steel tube market is still ahead .
