steel pipe

 The large-diameter thick-walled steel pipe has super strong bearing performance and can withstand a large impact force. It is widely used in the frame at present. When the vehicle is turning at a high speed or braking and stopping suddenly, the high-strength steel pipe can easily digest the strong impact. The impact force ensures the safety and maneuverability of the vehicle in emergency driving situations, and protects the vehicle body well. Why does the thick-walled large-diameter carbon seamless steel pipe have such a good bearing capacity? Practice has proved that there is an approximate corresponding relationship between the hardness value and the strength value between various hardness values of metal materials, which ensures that the thick-walled large-diameter seamless steel pipe has such a good bearing capacity. Steel pipe bearing capacity. Because the hardness value is determined by the initial plastic deformation resistance and the continued plastic deformation resistan...

 At the beginning of 2019, after half a year of order negotiation, our prison piling project with New Zealand officially started production. during the production Tianjin Xinyue Steel also has a team of professional engineers stationed in the factory for this batch of high-frequency resistance welding processing. Production and quality inspection are carried out throughout the construction process. Prior to production, due to design modifications by the end customer, the length was changed and the frequency of inspections was increased. Although it has brought great difficulty to our production, Xinyue Group has responded to the new requirements of customers, coordinated with the technical department in time, and fully meets customer requirements. In order to save costs, we provide customers with the best solution and customers. Repeated discussions to finalize the inspection plan. Due to the modification of the previous plan, resulting in delays in delivery, and fear of delaying c...

 For all the businessman in Xinyue Steel, everyday is fresh new, and also we will face various challenge everyday. In the workplace, how to finish all job perfectly in a limited time has become the common problem for all. To improve the work efficiency not only shorten the working time, raise the salary for one person but also increase the labor capability and economical efficiency for the enterprises. But How to improve it? Plan a clear work plan Without planning, it is messy every day, and I feel that I have done a lot of things, but there is no progress, so work plan planning is particularly important. A clear work plan was listed the night before or in the morning, and the time required for each task to be completed was set, creating a sense of urgency within the specified time. The work plan must be divided according to the urgency of the matter, such as the order of the inquiry, according to the working hours of each country. Recommend a plan to record the APP-wonder list, yo...

 In early January 2019, we received the inquiry for galvanized coil from a new customer in UAE, and Xinyue provided the best price to the customer in time. The client asked for delivery within half a month, but it happened to be the Chinese Spring Festival at that time. The customer could understand the practical difficulties in scheduling production, and finally agreed the delivery in mid of March,a and confirmed the trial order. Although it is only 110 tons for this order, but no matter bulk or small quantitiy for the order, we always taking service in priority, customer first. We actively checked various technical requirements with customers, completed production and inspection as scheduled in March, and finally delivered smoothly. The final destination port of this batch of galvanized coils is Libya. Last year, our company exported 3,000 tons of welded pipes to Libya. With these two orders, Xinyue has a deeper understanding of the African market, and will comprehensively promot...

Surface machining defects of seamless steel tubes and their prevention: 1.The surface processing of seamless steel tubes mainly includes: surface shot peening, overall surface grinding and mechanical processing. 2.Purpose: To further improve the surface quality and dimensional accuracy of seamless steel pipes. 3.The tools for overall grinding of the outer surface of the seamless steel tube mainly include: abrasive belt, grinding wheel and grinding machine. Some small defects on the surface of the steel pipe such as small cracks, hair lines, pits, scratches, etc. ①Use the abrasive belt or grinding wheel to grind the surface of the steel pipe as a whole, and the possible quality defects mainly include: black skin on the surface of the steel pipe, excessive wall thickness, plane (polygon), pits, burns and wear marks. ②The black skin on the surface of the steel pipe is because the grinding amount is too small or there are pits on the surface of the steel pipe. Increasing the grinding amoun...
