Brief introduction of Deyang small diameter thick wall alloy steel pipe
? Alloy steel pipe can be divided into three types: ordinary, light and wide flange I-beams, which are indicated by the number of plus signs after the symbol "I". The number represents the CM number of the section height, for example, i16 represents the I-beam with the height of 16 cm. According to the thickness of the web, I-beams with the same number can be divided into three specifications: A, B and E. type A is the thinnest and the most economical. For example, the height of i32a is 32cm, and the thickness of I-beam is class A. The thinner the web thickness is, the lighter the weight is, and the moment of inertia of the section is relatively large. Common alloy steel pipe has i10c ~ i63c.
The light-weight i-flange and ql0b are more stable than the light-weight ones. Wide flange I-beam, also known as H-shaped steel, has a large increase in overall stability and section bending stiffness. HK stands for wide flange H-beam and Hz stands for narrow flange H-beam.
Profiled steel sheeting. Profiled steel sheet is formed by cold pressing or cold rolling of hot rolled steel sheet, which has large width and zigzag shape, thus increasing the moment of inertia and stiffness, and is widely used. It is mainly used for roof slab, wall panel, etc. it can also be made into color steel plate and heat preservation composite plate, with V-shaped, rib shaped and wave shaped shapes. The wave height is 10-200 mm, the plate thickness is 0.4-1.6 mm (roof panel and wall panel), and more than 2-3 mm (floor slab).

The apparent consumption of crude steel in China reached 450 million tons, a year-on-year increase of 44.04 million tons and a year-on-year increase of 10.9%. From the perspective of the supply and demand situation in the later stage, the environmental protection and production restriction measures in the heating season will have a certain impact on the supply. However, with the rapid release of the dominant production capacity, there will be no big gap in the market in the later stage, and the price is difficult to rise sharply, and it will be in a fluctuating trend. At the beginning of the week, the price of domestic welded pipe is rising sharply. According to the monitoring data of Lange steel cloud business platform, the average price of 4-inch (3.75mm) welded pipe in domestic key cities is 4446 yuan, which is 75 yuan higher than last Friday, including Tangshan, Tianjin, Xi'an, Wuhan, Shenyang, Shanghai, Jinan, Guangzhou, Chengdu and Beijing. At the end of last week, with the appearance of Benxi Iron and Steel Co., Ltd., black broke through the suppression instantly. Affected by this, the price of raw steel strip has been continuously raised since the weekend. In terms of price, with the sharp rise of upstream strip steel price, domestic welded pipe quotation keeps rising. At present, Tangshan mainstream factory quotation is about 4350 yuan, which is 100 yuan higher than last Friday, but the overall transaction of pipe plant is not so good.
