On November 7, the China Iron and Steel Association said that in October, affected by the country's steady growth policy measures, the market is expected to rise, and the release of steel production capacity remains at a high level, driving demand for iron ore and rising prices. The post-market will soon enter the low season of Q345C seamless steel pipe consumption, steel output will decrease, iron ore demand intensity will decline, and prices will not continue to rise, will be slightly fluctuating.

Recently, the price of 45# seamless steel pipe has skyrocketed and plummeted. After the violent rise, the market quickly returned to calm. According to industry analysts, the current stock market of 45# seamless steel pipe is still low, and the market is steadily rising. It is worth looking forward to the recent surge in the price of 45# seamless steel pipe. After the violent rise, the market quickly returned to calm. According to industry analysts, the current stock market of 45# seamless steel pipe is still low, and the market is steadily rising.

According to the German Business Daily reported in May 11th, June 1st is approaching.

　　Large-diameter seamless pipe prices fall back to the market with a wait-and-see attitude

In the exploration and development of petroleum companies, the processing quality of oil casing threads is directly related to the exploration and development benefits. This is mainly because the thread is the joint part, so it is the weakest link, so it is often the area with high accidents. In the process of oil casing thread processing, there are often quality defects of one kind or another. Based on this background, this paper analyzes the quality defects of oil casing thread processing in combination with its own working practice, and puts forward some points of view on strengthening the thread processing of oil casing.

Method of operation: After heating the steel to Ac3+30~50 degrees or Ac1+30~50 degrees or below Ac1 (you can refer to the relevant information), it will generally cool slowly with the furnace temperature.

Mainly used for general engineering structures and mechanical structures. Its representative material (brand): carbon steel 20, 45 steel; alloy steel Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo, 42CrMo and so on.

　　This week, the domestic seamless steel pipe market of No. 45 showed a steady upward trend.

After the stainless steel tube cold billet is heated, there is generally a temperature difference between the radial direction and the axial direction.

What is the type of line pipe tempering? According to the performance requirements of pipeline steel pipes, depending on the tempering temperature, tempering can be divided into the following types:

1. Introduction to seamless steel pipe The seamless steel pipe is a circular, square, rectangular steel with a hollow section and no seams around it. The seamless steel pipe is formed by perforating a steel ingot or a solid tube blank, and then hot rolled, cold rolled or cold drawn. The seamless steel pipe has a hollow section and is used as a pipe for conveying fluid. Compared with a solid steel such as round steel, the steel pipe has a lighter weight when it has the same bending and torsional strength, and is an economical section steel which is widely used for manufacturing structures. Parts and mechanical parts, such as steel scaffolding for oil drills.

An ISO 9001:2008 certified company, Victor Steel supplies a wide range of ASTM A312 TP 316L Stainless Steel Seamless Pipe to customers across world.Our focus is on providing customers with high end steels that are not rolled or stocked locally.

The invention provides a protective coating for oil pipes and wellheads and downhole equipment used in oil and gas drilling, oil recovery and transportation.

High-quality resources are tight and the price is high. Some mines have increased mine use, mine sales are better, traders are more active, and small and medium-sized mines are starting to improve slightly.

Q345 channel steel price market traditional sales season, and because of the "golden nine" market failure, the market will habitually think that the delay of the peak season, may eventually fall to October, so before the National Day, the market for " The Silver Ten” peak season still has high expectations, and after the steel price has been consolidated for more than a month, there are conditions for a rebound.

The steel market continued its rebound last week. In addition to the weak and weak market, other major varieties of construction steel continued to rise.

A105 is the American ASTM standard number, and A stands for ordinary carbon structural steel.

The application of galvanized flat steel has also expanded correspondingly with the development of industry and agriculture. Therefore, the enterprises engaged in the production of galvanized flat steel in China are also required to have higher requirements for the galvanized flat steel. It is also because of the high new reference price of galvanized flat steel, so the production and process requirements are also very high, so the application range and type of flat steel is also very rich. So what is the difference between galvanized flat steel and round steel?

Structural performance comparison of seamless steel tubes. Carbon structural steel pipe: This kind of structural steel pipe is generally smelted by converter or open hearth furnace. Its main raw material is molten iron and scrap steel. The content of sulfur and phosphorus in steel is higher than that of high quality carbon structural steel pipe. Generally, sulfur is ≤0.050% and phosphorus is ≤0.045%.

On June 20, 2018, the U.S. Department of Commerce announced the initial subsidy of large-diameter Welded Pipes imported from China, India, South Korea, and Turkey.
