 In August 2018, Tianjin Xinyue Steel Group just finished PANAMA port construction project, on Oct, clients start to use it and expressed their gratitude for the high quality and on-time delivery. In the same month, the client from their contracting company sent an new enquiry, the project is about the new construction project for South America 4KM port. The client told us, we were not in the supplier list in the very beginning, but after the PANAMA project with good feedback from client, they decided to include us into their supplier list for their future projects, thanks for the trust! As to this project, Xinyue Steel successfully dealt with many technical problems from the client like coating application, welding technics, and also with our great enthusiasm and professional altitude so that the client will know that we take their project seriously and also our professional technics. After two month negotiation and mill inspection, Xinyue Steel Group has finaly awarded this proje...

 During the processing of cold-drawn precision steel pipes, there are cold hardening and hydrogen embrittlement, which are the key reasons for the cracking of cold-drawn seamless steel pipes. Harm of cold work hardening Seamless steel pipes cause a lot of plastic deformation during cold drawing, resulting in significant changes in lattice constants, which in turn increase the kinetic energy of lattice constants, and metal materials can be improved, resulting in uneven internal stress of metal materials, resulting in residual thermal stress. This will increase the hardness of the metal and reduce the ductility. The higher the hardness of the metal, the greater the residual thermal stress during cold drawing, and the more pronounced the cold work hardening. When the internal stress reaches a certain standard value, the metal material will be torn along a certain column of crystal pages, resulting in the crack of the seamless steel pipe. Hazards of hydrogen embrittlement state In the ...

 At the end of January 2019, Tianjin Xinyue Steel Group received a letter of credit from a North America customer. Successfully won the order of the North America bridging project ERW, no doubt this order is a new beginning of the new year, a new journey. The inquiry for this project can be traced back to July 2018. The customer communicated with our production department during the design processing, hoping to optimize the best cost and ensure the technical requirements. However, Tianjin Xinyue's production department and project department submitted steel pipe specifications and lengths for customers' reference due to the rich experience of piling projects operated before, and gave the optimized transportation plan for the final length determined. After several months of discussion and communication, I finally confirmed the details. However, considering the large number, the customer is still slightly worried about the quality of the factory. Tianjin Xinyue clearly stated tha...

 Jan of the year of 2019, is the last month before Chinese Festival Spring holiday, XINYUE people spent a crazy busy and enrich this month. As the CNY is coming soon, many customer require to ship out goods before holday. Adhering to the principle of customer first, Xinyue's quality inspection department and shipping department has made a perfect victory in order to ensure that the goods with good quality can be shipped on schedule, overtime, and every second. All goods exported by Xinyue must pass the strict inspection by the quality inspection department. All products must pass all tests before shipping. For each order, our quality inspection part is meticulous. Every test data will be carefully recorded, and products that fail to meet the standard will not be allowed to be shipped and will be re-produced until they are qualified. For large-diameter pipe shipments, our shipping department is very experienced. Whether it is a long length pipe or a large-diameter or coated pipe, it...

 Accompanied by our sales department and technical department, on January, 2019, we ushered in the inspection of seamless boiler tubes for Malaysian customers by third party Lloyd’s inspectors. The seamless boiler tubes produced this time are used in the American boiler project and require a wide range of performance requirements. During the inspection, we led the quality inspectors to visit the production line and the factory. The quality inspector has a better understanding of the production process and products, and submitted a complete set of production process documents. We started the final inspection of this project. The standard materials and dimensions of this inspection project are: BS3059 PT2 CAT2 Grade 360 50.8*3.2*5M, 6M, 8M. The quality inspectors are very professional in the inspection of the steel pipe size, and on-site sampling, witnessed the physical and chemical experiments, and witnessed the 10% online eddy current experiment. Finally, a 10% order quantity inspe...

 In order to ensure that “tube pulling” and “tube stacking” do not occur in the forming section, welding section and sizing section, according to the rolling principle of high-frequency straight seam welded pipe (ERW), it is necessary to ensure that the welded tube blank maintains proper tension in each section. In addition to the pass speed and rolling force, the factors that affect the tension are the sizing allowance, the outer diameter of the welded pipe, the wall thickness, the deformation method, the raw material of the tube blank, the coolant, the pass shape and the surface roughness, etc. If it is large, the hole pattern is easy to wear, the strip joint is broken, and the tension is too small, and the welded pipe cannot run stably in the sizing roller, resulting in “tube stacking”. Coordination of tension between sizing section and welding section: During the welding process, the perimeter of the welded pipe blank in the welding section is shortened after being squeezed by ...

 The busy Spring Festival holidays quietly went, and we also officially started construction on February 12. New Year's New Meteorology, from the beginning of 2019, according to statistics, Xinyue export orders have exceeded 20,000 tons. Prosperity, every Xinyue person is actively working hard. In the last few days before the holidays, we also finalized our cooperation with Southeast Asia Petro once again. After one month's negotiation, the project ordered 600 tons of spiral steel pipe. From the supplier qualification audit to product technical documents audit, Xinyue has always been the first choice for customers. Compared with the straight submerged arc steel pipe, the pipe specifications are more in line with the production process of spiral steel pipe. After submitting a series of successful project documents for the second largest oil company supplying for Venezuela, Australia, Pakistan and Greece, Xinyue finally gained the trust of the end customers and won the project fr...

 Tianjin xinyue steel group, a steel enterprise with temperature. Over the past decade, we have been dedicated to providing one-stop steel pipe service, providing professional steel pipe service solutions for domestic and foreign markets, and providing high-quality steel products for many large international oil field projects and urban infrastructure projects. At the same time, in order to better provide customers with a complete service and product system, we should also according to customer requirements, based on different project requirements and standard requirements, to provide imported products and services. In year 2018, in order to provide Vietnam's state-owned mining project with a full set of high-quality materials, we imported steel from the Middle East under the EN10034 standard, and finally delivered the supporting materials to the project site perfectly. Based on our import experience, we would like to share the following information with you: When you need to impor...
