Advantages and disadvantages of cold rolled steel pipe process Cold rolled steel pipe refers to the steel plate or steel strip processed into various types of steel at room temperature through cold drawing, cold bending, cold drawing and other cold processing. Advantages of cold rolled steel pipe: The molding speed is fast, the output is high, and the coating is not damaged, and it can be made into a variety of cross section forms to meet the needs of the use conditions; Cold rolling can produce great plastic deformation of steel, thus increasing the yield point of steel. Cold rolled steel pipe defects: 1. Although there is no hot plastic compression in the molding process, there is still residual stress in the section, which will inevitably affect the overall and local buckling characteristics of the steel; 2. The cold rolled steel style is generally an open section, which makes the free torsional stiffness of the section low. It is easy to appear torsion when bending, and easy to appear bending and torsional buckling when pressurized, and the torsional resistance is poor;

A brief analysis of seamless carbon steel pipe and welded pipe in China at the end of the year Looking back at China's domestic carbon steel welded pipe and welded pipe market from January to November 2023, the price as a whole shows a trend of rising and then falling, and then recovering and strengthening, especially after June, the price of welded pipe has been in a narrow range of fluctuations. Although the price of welded pipe in the market has risen in recent years, the increase is limited, and traders' profits are meager. The market entered the winter, the pipe factory inventory fell to the lowest level in history, and the price of welded pipes was supported, but by the seasonal impact, downstream demand contracted, and the market trend of "price without market" gradually emerged. 1. Market price Looking back at the welded pipe market in 2023, the price as a whole shows a trend of rising and then falling, and then shaking and strengthening. In the early first quarter, affected by the optimization of the epidemic policy and environmental protection policies, the market expectation is strong, the market supply and demand fundamentals are relatively balanced, the average price of welded pipes in the country shows a trend of rising and shaking, and the welded pipe price appears the highest point in mid-March. However,

Turkey rebar quotation climbed Vietnam steel market confidence boost China exports: In terms of rebar, Zhangjiagang B500B rebar export prices rose slightly by $5 / ton compared with last week. This week, despite the poor level of rebar futures, it is unlikely to have a direct significant impact on seaborne spot prices, and market sentiment has not been affected by the level. Wire, export prices rose slightly this week. Our company learned through Mysteel that due to the low cost of rerolling, the rerolling mill did not actively buy billets to produce wire rods, and the wire mill did not actively increase production even though it suffered losses for several months. On the whole, China's domestic market demand has been strong recently, while the supply is relatively limited, and the appreciation of the yuan has made the market situation worse, and the overall performance of the export market is not as good as the domestic market. Asia: This week, Asian merchants rebar prices remained stable, the market activity is relatively calm. Shandong Fengbao Metal Products Co., Ltd. learned through Mysteel that there was a deal in Singap

As steel prices in Asia continued the upward momentum of the previous 2 weeks, global steel prices showed a comprehensive upward trend this week. Including Japan, Europe, North America, China, Turkey and other major steel-producing countries of the leading steel mills have basically announced a new round of increase, due to the basic synchronous rise in raw material prices and become the main factor to boost the price of finished steel, while demand in most areas has not improved significantly, so the profitability of steel mills is still relatively severe. For example, in the European market, the increase in production costs, including iron ore, scrap steel, energy, freight rates, is compounded in the off-season consumption, and many steel mills have reduced production. That has prompted mills to raise output prices, even though orders have not improved. In Asia, due to the continued strength of the RMB, as a major exporter of galvanized round pipe, seamless carbon steel pipe, alloy steel tube, pressure vessel steel plate and other steel products, China's steel offshore US dollar prices have been boosted, which has supported the steel prices in Asia to a certain extent. However, including China, Turkey, Japan, Vietnam and other steel

Chinese export Medium and thick plate exports: this week with the appreciation of the renminbi and the overall upward price level of the plate, the price of the medium board has also risen, but the increase is significantly smaller than the hot-rolled coil, and the increase of different port resources is 5-10 US dollars/ton. Our company learned from individual steel mill news that the recent increase of carbon steel plate is low compared to hot coil, and partly due to a slight reduction in the supply side, superimposed raw material prices are similar, and the factory efficiency is still not good. At present, the main delivery date of mid-board exports entered February, and the transaction this week was slightly improved from last week. Southeast Asia With the strengthening of the RMB against the US dollar and the rise of China's domestic market this week, the export prices of the Asian sector have continued to rise, the market mostly shows a wait-and-see attitude, generally speaking, the price in November is better than in October, the increase is obvious, export prices in the premise of poor demand, still need to maintain a competitive advantage in prices, so the space is not obvious. It is reported that Vietnam's local steel mill Formosa Ha Tinh has sold out of the November hot roll quota, and local buyers are considering importing from foreign countries. Cold drawn steel pipe.In terms of seamless carbon

On November 17, the domestic steel market rose mainly. From the perspective of transaction, the period snail high rebound, most cities spot prices are high and low, and merchants feedback downstream procurement enthusiasm is poor. On the same day, nine domestic steel mills raised the factory price of construction steel 10-50 yuan/ton.Especially in alloy steel tube, cold drawn seamless round pipe, carbon steel boiler tube, high manganese steel plate, pressure vessel steel plate and many other carbon steel products. From the industry data point of view, rebar production increased slightly this week, the inventory decline narrowed, the table fell, and the data was neutral and weak. In terms of hot rolled coil, the recent macro policy boost news is more, in the case of raw material prices continue to rise strongly, the material price passively rises, the demand is less than expected, the short-term relative high led to the downstream to take goods cautiously, and the demand has not seen a significant rebound for the time being. The demand performance of the thick plate is not as e

What is the seamless carbon steel pipe? Carbon steel seamless pipe is a kind of long strip steel. The steel pipe has a hollow cross-section and is used in a large amount as a pipe for conveying fluids, such as pipes for transporting petroleum, natural gas, coal gas, water, and certain solid materials. Compared with solid steel such as round steel, steel pipes have the same light-bearing and torsional strength and lighter weight. They are economical cross-section steels and widely used in the manufacture of structural and mechanical parts such as oil drill pipes, automobile transmission shafts, Bicycle racks and steel scaffolds used in construction. The use of steel pipes to make ring-shaped parts can increase the material utilization rate, simplify the manufacturing process, save materials and processing man-hours, such as rolling bearing rings, jack sleeves, etc. Currently, steel pipes are widely used for manufacturing. The steel pipe is also an indispensable material for various conventional weapons. The barrels, barrels, etc. must be made of steel pipes. Steel tubes can be divided into round tubes and shaped tubes according to the shape of the cross-sectional area. Since the circle area is the largest under the condition of the same circumference, more fluid can be transported by the circular tube.
