• Concerns Over Safety and Environmental Impact of Petroleum Pipeline Prompt Thorough Review by Government Officials

  2023 / 04 / 17

  In recent news, a petroleum pipeline has been the center of attention due to concerns over safety and environmental impact. The pipeline in question, which stretches over hundreds of miles, is used to transport petroleum products such as gasoline, diesel, and jet fuel. The pipeline is owned and operated by a major oil company and is an essential part of the nation's energy infrastructure. However, recent events have brought the safety of the pipeline into question. In one incident, a section of the pipeline ruptured, causing a significant spill of petroleum products into nearby waterways. This spill has had a severe impact on the environment and wildlife in the area. The company has responded to these concerns by stating that they are taking all necessary measures to ensure the safety of the pipeline. This includes regular inspections and maintenance, as well as investments in new technologies to detect potential issues before they can cause significant harm. Despit

  20G seamless tube continuous quenching is to better ensure the characteristics of the plate, pickling passivation is to ensure the surface quality. To a certain extent, it can ensure the use of 20G seamless steel pipe throughout the later stage. In the continuous quenching of 20G seamless pipe and its pickling process, the pickling passivation section is the key component of the generator set. The acid management method is the key way to ensure the normal and smooth operation of the pickling passivation section, which is particularly important for the process performance of hot rolled strip and the effective use of acid. The basic core concept of acid management is to maintain the stability of the ion concentration of metal materials in the acid solution, so as to ensure the best and stable practical effect of pickling passivation.In specific production, for the mixed acid pickling passivation section, the mixed acid tank generally located in the middle and downstream of the production line will specify a lower ion concentration of the metal material to ensure the actual effect of the final pickling passivation. It has the ability to resist air and air oxidation, and also has the ability to corrode in substances containing acids, alkalis and salts, that is, corrosion resistance. However, the size of its corrosion resistance work capacity varies with the organic chemical composition of its steel, interactions, application standards and the type of natural environmental substances.In order to achieve this overall goal, first of all, according to the steel grade of hot-rolled strip, the amount of pickling passivation section per unit area, clarify the zinc ash composition of the surface layer of hot-rolled strip and the concentration value of the required acid, the acid intelligent management system will automatically carry out relevant measurements, clarify the amount of new acid added and waste acid consumption, and carry out relevant practical operations according t

• Introduction of hot stamping forming process for seamless steel pipe

  2023 / 04 / 06

  The purpose of this process is to heat the seamless steel pipe to a suitable temperature, so that the wear-resistant pipe is completely martensite and has excellent plastic deformation. The mechanical equipment used for heating is a dedicated continuous heat treatment furnace. After heating above the work hardening temperature, the surface layer is easily oxidized in the air to form oxide scale, which causes adverse damage to subsequent production and processing. In order to better prevent or reduce the air oxidation of wear-resistant pipes in the heat treatment furnace, a rare gas protection system is generally set in the heat treatment furnace, or the surface oxidation treatment of the pipe refers to the removal of the heated seamless steel pipe from the heat treatment furnace and put into the thermoforming mold. In this process, it is necessary to ensure that the wear-resistant tube is migrated to the mold as soon as possible. On the one hand, it is to better avoid air oxidation of seamless steel pipe at high temperature, and on the other hand, it is to better ensure wear resistance. The pipe is still at a high temperature when it is formed, and it has excellent plastic deformation. Stamping die and heat treatment: After the wear-resistant pipe is put into the mold, the stamping die should be formed on the seamless steel pipe immediately to avoid excessive temperature drop affecting the forming characteristics of the wear-resistant pipe. After molding, the mold shell should be closed and maintained at a pressure for a period of time. On the one hand, it is to better control the appearance of the part. The body of the body, producing excellent specification accuracy and physical properties. Studies have shown that at this stage, the minimum cooling rate of ordinary hot stamping mold stainless steel sheet to complete the transformation of martensite to austenite is 27~30 °C/s, so it is necessary to ensure that the cooling rate of the mold shell to the pipe exceeds
