According to the latest market report, the domestic galvanized seamless steel pipe spot steel market is still rising, and the average weekly increase in the most recent week is about 1.35%. The galvanized seamless steel pipe has continued to strengthen since July; the ex-factory price of steel mills has risen and the prices of raw materials have risen steadily; the “environmental storms” in some regions of China have shown signs of substantial advancement, all of which directly contribute to the domestic spot steel market. The role. Only after the steel price rose, the transactions in some markets slipped, and cautious merchants began to cash in, and some of the quotations gradually stabilized.

The Ministry of Commerce website reported on June 15 that the Ministry of Commerce has just issued a "Notice on the review of the investigation and review of the anti-dumping measures against the import of high-temperature pressure-bearing alloy steel seamless steel pipes for the United States and the European Union."

With the recent decline in the price of seamless steel pipes, the disk has already seen the support of cost and high discount. The current rhythm is that the spot decline has increased, but the futures decline has slowed down. The key to how the premium is finally repaired is when the spot will stop falling and the time of inventory accumulation.

Q345B low-alloy seamless steel pipe news report said: the downward pressure on the economy and the optimization of macro-control policies triggered the market's conjecture on the regulation of the property market. This kind of speculation is not in line with the continuous tightening of the current situation of the property market regulation, and is not conducive to the medium- and long-term pursuit of economic transformation and upgrading. At the same time of macro-tuning optimization, insisting on the regulation of the property market is not relaxing, aiming to guide the flow of financial living water to the physical field where more funds are needed for irrigation, to prevent the real estate bubble from being blown up again, and to create a thicker “safety pad” for economic structural transformation.

At the 2nd China Iron and Steel Financial Derivatives International Conference held in Shanghai on June 16th, Wang Mingwei, the director of the medium-term association, said that the futures market provides a market-oriented means for steel enterprise risk management, which can effectively help steel enterprises manage sales price risk and control. Purchasing costs, optimizing inventory management, rationally arranging and adjusting production plans can also help companies reduce costs and increase efficiency, improve profitability and competitiveness, optimize industrial structure and trade forms, and promote transformation and upgrading of the entire industry.

Today, the overall market of Shanghai No. 10 steel pipe market is still good, but the price increase is generally strong. At present, there is still a wait-and-see attitude for the market as a whole, and the current terminal market demand has not yet been released.

Iron ore as raw material end in the third quarter is affected by environmental restrictions on production, demand is limited, but due to sea freight greatly increased and the depreciation of the RMB, its spot price in 500-600 yuan / ton oscillating operation. As of October 11, 61.5% of Australia's PB wet-based duty-bearing vehicle plates in Qingdao Port were priced at 530 yuan / ton and the iron ore index (62%) was $70.05 per ton. Steel mills have high profits.

Always in pipeline systems we met the material with NACE MR0175/ISO 15156 pipe or fittings, so do you really know what is the major differences between NACE carbon pipe and normal carbon steel pipe? And how is the cost for nace material?

Washington: The US International Trade Commission on Thursday said it had determined that American producers were being harmed by imports of certain large-diameter welded steel pipe from China and India, a finding that locks in duties on those products for five years.

My steel: Last week, the domestic steel market price fluctuated. Although last week's spot resources were supported by the improvement of the futures and billet prices, the market price still needs demand support. Therefore, for some varieties with smooth shipments, the price has a certain difficulty and easy to fall. However, for the region, some of the market has a backlog of resources after the holiday, most of the operations are mainly maintained by fast shipments, and the price increase is restrained, so the merchants are more cautious. In the fourth quarter, it is difficult to relax the environmental protection policy. Although some regional stocks are under pressure, most of the pessimistic situation of the previous business has improved in the previous week. Therefore, it is expected that the domestic steel market price will be this week (2018.10.15-2018.10.19). Or run in a narrow range.

On October 30th, the 7th Baosteel Academic Annual Conference with the theme of “Green Steel, Smart Manufacturing” was opened at the China Baowu Central Research Institute.

At present, domestic steel pipe manufacturers face the great challenge of overcapacity in seamless steel pipe, have adjusted the variety structure, eliminated backward production capacity and developed high-quality products. The experimental results show that the controlled cooling process in the hot rolling process of seamless steel tube can control the microstructure phase change process, refine the grain, and improve the mechanical properties of the steel tube.

ASMT A333 1 seamless and welded pipes should be treated to control their microstructure. Tensile test, impact test, hydrostatic test and non-destructive electrical test shall be carried out according to the prescribed requirements. ASTM A333 1 is part of the standard covering wall seamless and welded carbon and alloy steel tubes, designed for low temperature use. ASTM A333 1 grade alloy pipe should be manufactured by seamless or welding process without filler metal in welding operation. Seamless and welded steel tubes for low temperature service:

Capillary rolling is the main deformation process of seamless steel tube production. Its function is to make the wall thickness of the capillary close to or reach the thickness of the finished tube wall, and eliminate the non-uniform thickness of the longitudinal wall generated by the capillary in the process of perforation. The surface quality of the internal and external parts of the waste pipe is controlled, and the outer diameter and roundness of the waste pipe are controlled. The hollow capillary is rolled into a waste pipe near the final size.

1mechanical polishing The 1. advantage is that the parts are smooth and the brightness is high after processing. The disadvantage is that the labor intensity is too big, cause serious pollution, can not process complex parts, the luster can not be consistent, the heat preservation time is not long, the mechanical polishing is suitable for the processing simple parts, and the small and medium parts.

According to foreign media reports, US steel prices seem to be affected by 232 tariffs, tinplate prices are rising sharply, and tinplate manufacturers will reflect price increases in negotiations with customers in 2019. It is reported that since the price of hot rolled strip of raw materials for tinplate production has increased, the price of tinplate in the United States has increased by more than $350/ton since last year. US tinplate manufacturers will begin negotiations with customers on prices starting in 2019 this fall. They will require a 50% price increase when the tinplate price is at a high market level and a 30% price increase when it is at a low market level, which is in line with the price increase of hot rolled products.

Type 304 stainless steel is one of the most common and most commonly used stainless steel grades. It is a chromium nickel austenitic alloy, which contains at least 18% chromium and 8% nickel, which contains up to 0.08% carbon. It can not be hardened by heat treatment, but cold working can produce higher tensile strength. Chromium and nickel alloys provide corrosion resistance and oxidation resistance far better than steel or iron for Type 304. It has a lower carbon content than 302, which minimizes chromium carbide precipitation due to welding and intergranular corrosion. It has excellent molding and welding characteristics. The ultimate tensile strength of the 304 type is 51500 psi, the yield strength is 20500 psi, and the elongation is 40%, 2 ". Type 304 stainless steel has many different sizes and shapes, including rods, corners, circles, plates, slots and beams. This kind of steel is used in many industries for many different purposes. Some examples are food processing equipment, kitchen equipment and appliances, panels, decorations, chemical containers, fasteners, springs and so on.
