steel tube

 The old customer in Africa has cooperated with our company for more than 5 years. Our customers mainly purchase small diameter square and rectangular tube and round tube,but the mainly product is square and rectangular tube.During the 5 years of cooperation, our customers have placed great trust in us and are satisfied with our quality and service.During the years of cooperation, customers have very strict requirements on container loading, which can save high container freight and save costs for customers. The tenet of xinyue is to serve every customer well. Under normal circumstances, containers can only hold 25 tons, but the customer requires 28 tons for each container. In order to meet the customer's requirements and save the customer's cost, xinyue logistics department tries to consider how to save the volume before packing. XinYue has professional packing workers , in the process of packing, cannot leave each givers hard labor, workers will place tubular steel pipe befor...

 Any project wants to be successful, need to provide the best service and the best quality for customers on a professional basis, not only to discuss with customers about various technical issues, but also to provide customers with samples for testing.In December 2019, our client in Kazakhstan tested the qualified sample pipeline, and the client was satisfied with our quality and began to push forward the project of seamless pipeline for fluid transportation. In January of this year, customers and us reported that we have successfully received this order and hope that we can deliver as soon as possible. At the time of the Chinese New Year holiday, customers expressed their understanding and waited patiently for us to resume work. In early February, affected by the new coronavirus epidemic, most factories were delayed in returning to work. After explaining the situation to the customer, in order not to delay the progress of the customer's project, our factory actively did epidemic p...

 Austenitic weld inspection within the oil and gas industry is one of the most important assets for professionals in this field. But the inspection process can be daunting without the right equipment. Austenitic alloys and stainless steel resist corrosion more than other materials but are not impervious to corrosive degradation. Therefore, NDT inspectors must implement the same rigorous NDT standards on austenitic alloys and stainless steel as any other item. The best way to test stainless steel and austenitic alloys is via PAUT using 2D matrix array probes. Stainless steel materials carry anisotropic coarse-grain content, with each grain causing reflections and high noise levels. The high noise levels result in greater feedback issues during conventional testing processes versus PAUT. Also, NDT specialists must deal with unintended variations within the structure of the pipeline, making testing difficult. When inspecting an austenitic weld, for example, NDT operators can use the 2...

 In order to optimize the production of blast furnace system and strengthen the technological transformation of energy-saving and environmental protection processes, since October 2019, the Maanshan Iron and Steel Plant has made a careful plan to penetrate the standards of the "energy-saving and environmental protection, green development" strategy into all aspects of enterprise development, and promote No. A blast furnace Major revisions to the construction of key energy-saving and environmental protection projects such as No. 3 sintering machine flue gas denitration and ultra-low emissions, to promote the high-quality development of blast furnace system production. In implementing the strategy of “Energy Conservation, Environmental Protection and Green Development”, the main plant adopted “two-handed, two-handed” measures: on the one hand, optimizing the production of the blast furnace system and strengthening the energy-saving and environmental-protection process and techn...

 In November 2019, Tianjin Xinyue established a preliminary contact with a steel pipe processing plant in Vietnam. In the first communication email, the customer stated that he was unwilling to spend too much time in negotiations, and we had only one chance. If the service cannot make him satisfied ,he will not reply any of our information in the future. Although the customer did not have a real purchase order at the time, he still sent us several specifications that often need to be purchased. Let us provide a solution reference. After receiving the customer's first inquiry, we made a comprehensive analysis. The customer's long-term purchase specifications are ERW welded pipes with sizes ranging from 2inch-10inch. Although the destination port is in Vietnam, the customer's standard requirement is the Australian standard BS1163 C350. We also infer that customers will have stricter quality control. It is gratifying and proud that Tianjin Xinyue has been supplying in the Aust...

 In December last year, we received an inquiry from a long-term Southeast Asian customer for 320 tons of large straight seams. The delivery date was originally agreed to be delivered in mid-February. Due to the epidemic, the steel mill delayed resumption, and the raw materials could not arrive at the steel plant for production as scheduled, resulting in a serious delivery period. The extension was postponed, and the customer itself was very anxious to wait for the steel pipe to start the project. In this way, the original plan of the construction party was disrupted. As a supplier, when it encountered such force majeure factors, it could only explain to the customer patiently and apply from the CCPIT. When the force majeure factor proves, The customer is also aware of the new coronary epidemic situation in China from all aspects. Although the plan was disrupted, they finally expressed understanding. At the same time, we kept very close contact with the customer and kept updating pr...

  Ⅰ.  High heat transfer coefficient of stainless steel pipe Stainless steel pipes have a high heat transfer coefficient. The heat transfer performance of stainless steel pipe is realized by its unique ultra-thin-walled steel pipe, which is a thin-walled pipe with continuous tangent between large and small arcs and corrugated inner and outer shapes. The height difference between the wave crest and the wave trough causes the fluid to be strongly disturbed. This disturbance comes from the three-dimensional movement of the fluid inside and outside the tube, so the degree of disturbance is more intense and thorough. Even if the fluid velocity is very low, it may become turbulent, and the temperature gradient of the thin-walled tube wall is very small. Ⅱ. High temperature resistence of stainless steel pipe Stainless steel pipes are very resistant to high temperatures. Although the stainless steel pipe has a thin wall (0.5-0.8mm), the pressure-bearing capacity of the steel pipe is g...
