Seamless steel pipe is one of the important products of OCTG products. It is widely used in manufacturing structural parts and mechanical parts, such as petroleum drill pipe, automobile transmission shaft, bicycle frame and steel scaffolding. Compared with other steel tubes, seamless steel tubes have stronger bending and torsion capacity under the same cross-sectional area. It is widely used in the national economy and has the right to "industrial vessels". Therefore, the quality requirements of seamless steel tubes are very demanding.

The European Union official gazette said that the EU will launch protective measures on Thursday (19th) to prevent a surge in steel imports into the EU after tariffs on imported steel and aluminum in the United States. The European Commission has proposed a combination of quotas and tariffs to address EU concerns, and the EU is concerned that steel products that are no longer exported to the United States may turn into the European market. The Lianhe Zaobao quoted Reuters as saying that the quota for 23 steel products was based on the import situation in the past three years, and the imported steel products exceeding the quota will be subject to a 25% tariff. According to reports, the countries that export steel to the EU are mainly China, India, Russia, South Korea, Turkey and Ukraine.

Many people think that stainless steel is not rust steel, of course. The stainless steel pipe elbow anti rust mechanism is to form compact alloy oxide film, isolate oxygen contact and prevent oxidation. So stainless steel is not "stainless steel". Stainless steel has the ability to resist atmospheric oxidation, that is, stainless steel, and has corrosion resistance in acid, alkali and salt media, that is, corrosion resistance. After the Prime steel pipe, the main factors affecting the corrosion of stainless steel are understood.

Tubes and bends in pneumatic conveying lines are suffering more or less abrasion. DMH United Steel's ceramic lined pipes resists abrasion and avoids product attrition.It reduces considerabley degradation of conveyed material and avoids formation of angel hair through its patented deflection chamber.The compact design reduces cost of pipe support and installation.

Low carbon steel tubes are made of ceramics with high wear resistance and resistance to fluid erosion. In the wind pipe, the wear rate of the pipe is the fastest, and the wear resistance of the ceramic lined steel pipe elbow is more than five times higher than that of the steel elbow. In practical application, the ceramic lined steel pipe has been observed and measured 1-2 years after opening the hole. The composite layer has no obvious wear or loss, the size of the unit and the length of the pipe are the same. The weight of the ceramic lined steel pipe is about 1/2 with the weight of the wear-resistant steel pipe or the double metal composite pipe. The construction cost is reduced by 30-40% per meter, and only the cast stone weight steel pipe is used. And rare wear resistant 2/5 around 20% per meter below the cost of the project. The cost of ceramic lined steel pipes is only a small part of stainless steel tubes and nickel titanium pipes when they are corroded or used in high temperature.

According to data from the Korean steel plate distribution industry, the Korean toll tax has been raised from the previous 10,000 won/ton to 12,000 won to 15,000 won/ton since the beginning of this year. The relevant industry also requested that the fee be raised to 18,000 won / ton. It is understood that there are still some unsold materials in the relevant Korean market, and the tolls of some unsold materials are charged according to the previous standard of 10,000 won/ton.

In the first half of July, the international steel market was first suppressed and then raised. In the middle of the month, the global steel benchmark price index of 123.7 points rose by 0.3% on a week-on-week basis.

The ceramic tube is the corundum and the inner corundum. The hardness of corundum layer Vivtorinox is 1100-1500 (Rockwell hardness 90-98), equivalent to tungsten cobalt hard gold. The high wear resistance is 20 times higher than that of the carbon steel pipe. It is superior to the ordinary corundum grinding wheel. It is still a variety of corundum grinding wheel grinding hardened steel main wheel. The ceramic Guan Gangyu corundum wear layer can be picked up. The wear-resistant ceramic tube corundum layer can be formed mainly by a few millimeters thick, the Moir hardness is 9, second only to the diamond and the silicon carbide, all oxides, this is the highest hardness. Only about 20% of alumina, most of which are SiO2, SiO2 Moir hardness is 7. rare high chromium wear resistant alloy tube or Vivtorinox hardness is about 400 (Rockwell hardness is about 50), and the hardness of corundum is third. Therefore, the wear resistance of wear-resistant alloy steel pipe and casting pipe is a qualitative leap from the composition and structure, and the thickness of ceramic tube compared with them.

Ceramic lined steel composite pipes have excellent wear resistance. The service life of materials used in hard abrasives is 20 times longer than that of ordinary steel pipes. The combination of high rigidity and high elastic steel makes the pipes unrivalled and can be used as wear-resistant, heat-resistant and corrosion resistant materials in the fields of power generation, metallurgy, mining and chemical industry.

The steel should meet the requirements of chemical composition, tensile properties and hardness. Water pressure test should be carried out in every pipe. In addition, each pipe should be inspected according to the required practice by NDT. Mechanical test requirements for different pipelines, such as lateral or longitudinal tensile tests, flattening tests and hardness or bending tests, are presented. The ends of each box will indicate order number, heat number, size, weight and binding or as required.
