The ASTM standard helps to classify, evaluate and specify the material, chemical, mechanical and metallurgical properties of different types of steel, which are mainly used for the production of mechanical components, industrial components and building components, and other accessories related to them. Steel can be carbon, structure, stainless steel, ferrite, austenite and alloy type

ASTM A500 tube is a standard specification for cold-formed welded and seamless carbon steel structural tubing in round, square and rectangular shapes. ASTM A500 is the most common specification in North America for Hollow Structural Sections (HSS). APPLICATIONS ASTM A500 applications include structural supports, building columns, highway signs, oil field services and communication towers.

CHARACTERISTICS A500 steel pipe can be subjected to most of the usual fabricating operations. Ductility is good. It bends well, flattens, cuts, punches, flares and flanges easily, and can be welded by the commonly-used techniques and practices. APPLICATIONS Common uses for ASTM A500 pipe include hand rails, posts, storage racks, displays, furniture, etc.

When steel pipe is completed and operational, it is the result of cooperation between a number of parties in the supply chain. These parties perform steps which are sequential and overlapping involved in the design, manufacturing, blasting, coating, handling, storage, transport and construction of steel pipe.

As the name suggests, seamless pipes are pipes without joints or welded joints, rather than welds or welded pipes. In joints or welded pipes, joints or welded joints are the weaker parts of pipelines, which limit the strength of pipes to achieve the strength of welded joints. Seamless pipe has no such joint, so it has uniform structure and strength on the whole pipe. Therefore, seamless tube can withstand higher pressure, higher temperature, higher mechanical stress and corrosive atmosphere, and is widely used in oil and natural gas, oil refinery, petrochemical, chemical, chemical fertilizer, electric power, automobile, bearing, mechanical and structural applications.

Hot-rolled seamless steel pipe production base deformation process can be summarized as three stages: perforation, extension and finishing.

There are cracks in the welding process or design of the stainless steel pipe joint at the other joint. In effective corrosion sites, the crack must be wide enough to allow corrosive electrolyte to enter the stagnant zone. The width of the corrosion crack is several meters wide, but it is not absolute. The critical crack size leads to corrosion.

Check and check the complete data of the stainless steel pipe. We know that stainless steel seamless pipes have high quality requirements for seamless pipes under high temperature and high pressure.

On May 22, 2018, Washington, Worthington Industries and Manchester Tank & Equipment Co. filed an application with the US Department of Commerce and the International Trade Commission requesting imports from China. Steel Propane Cylinders launched anti-dumping countervailing investigations and initiated anti-dumping investigations on products imported from Taiwan and Thailand. The products involved were mainly attributed to the US Customs Tariff Nos. 7311.00.0060 and 7311.00.0090. According to U.S. statistics, in 2017 I exported about $89.8 million to the United States. The U.S. Department of Commerce will decide whether or not to file a case on or about June 11, 2018

In May 22, 2018, Washington time, Worthington Industries and Manchester Worthington Co. (Manchester TG Co.) applied to the U. S. commerce department and the International Trade Commission to launch an anti - Steel Propane Cylinders imported from China (Steel Propane Cylinders). Dumping and countervailing investigations launched anti-dumping investigations on products imported from China's Taiwan and Thailand. The products involved are mainly attributable to us customs tariff No. 7311.00.0060 and 7311.00.0090. According to the US statistics, in 2017, I exported about $89 million 800 thousand to the US. The US Department of Commerce will decide whether to file a case in June 11, 2018 or so.

1, online nondestructive testing The detection arm of the testing station rotates and is placed on the longitudinal welded pipe production line. Observe the position of the weld through a camera. The position of the probe is adjusted by the lever so that the weld overlaps with the laser and saves the parameters. Input the coil number through DATASERVR and DACQ computer. The waveform of the observation defect detection interface is displayed. When the waveform exceeds the alarm line, the thickness measurement information is compared to determine whether it is a defective or interfering wave signal, and the naked eye is checked to see if the waveform is beyond the alarm line. If the alarm line exceeds the alarm line, the alarm will be issued. Close and adjust the welding parameters in time.

Requirements for the use of galvanized insulated steel pipes for buildings: 1, galvanized insulated steel pipes are used for long-distance transportation of natural gas and high pressure pipes.

Seamless casing is an important equipment for oil drilling. It is also the other equipment of drilling and drilling, core pipe, casing, drilling, small diameter drilling casing and so on. The support of the borehole ensures that the drilling process stops and the well is fully operated after completion. Therefore, processing oil drilling to eliminate the problem of wear-resistant drill rod, it is difficult to dismantle the drill rod joint performance when the external wear belt is difficult to disassemble, the operation is complicated and safe, the degree of automation is high, the joint efficiency is high, and the cutting is clean. For a wide range of pipe diameter, the music tone is small, and the use of oil sleeve will not clean the environment, equipment debugging is also very convenient.

With the double-digit decline in exports to the traditional largest overseas market, Southeast Asia, Chinese steel companies are looking for new export destinations in Africa and South America. According to experts, it is clear that the export opportunities for Chinese steel companies are becoming increasingly limited. Since last year, China’s steel exports to Vietnam, South Korea and other traditional markets have dropped at a double-digit rate, which reflects fierce competition from strong competitors such as Russia. In addition, anti-dumping tariffs imposed on Chinese steel products by Southeast Asian countries such as Thailand, Vietnam, Indonesia, and Malaysia have also affected China's steel exports. Last year, exports to South America and Africa accounted for 8% of China’s steel exports. Since the beginning of this year, China’s steel exports to some countries in these regions have seen significant growth. According to the report, according to the WTO data, compared with Asian countries, fewer countries in Africa and South America implement anti-dumping duties and related trade protection measures on Chinese steel products. As Chinese steel companies gradually deepen into these markets, they may have an impact on domestic steel companies such as Brazil.

The U.S. Department of Commerce announced on the 20th that it has approved the first applications for steel products that are exempted from the U.S. "232" tariff.
