 In June 2019, we received an inquiry about the seamless stock order from India customer. This inquiry is similar of the order of last year. Due to the successful experience of last year, Xinyue provided the quotation and inspection plan according to the market situation. Communicate new technical requirements with customers, and strive to meet customers' quality requirements in the production process.With the support of our technical department and production department, the technical documents and production process control documents provided by us have relieved customers of their worries. Regarding the customer's concerns about the delivery time, Xinyue discussed with the production department and communicated with the customer about the delivery time after comprehensive consideration to guarantee the timely delivery.The customer expressed the high trust to Xinyue Steel and placed the order to Xinyue Steel Group. This order requires the third party inspection to issue an IBR...

 Seamless steel pipes are often used as raw materials for ring-shaped metal material parts, which not only saves a lot of complicated technological processes, but also greatly reduces the wear and tear of stainless steel plates in the production process and saves product costs. The basic principle of this kind of production and processing is not difficult to understand. It is a bit similar to cutting kale, and you can quickly get ring-shaped parts by cutting it with a knife, reducing the wear and tear to a minimum. The above are all seamless steel pipes with annular cross-sections. Such annular seamless steel pipes are not perfect. Their bending strength is relatively poor and cannot bear a lot of force. Therefore, they are used in agricultural machinery. In the frame, furniture and other applications, the seamless steel pipe will be forged into a square or rectangular frame to improve the tensile strength of the seamless steel pipe. Seamless steel pipes generally refer to seamless...

 In 2019, Tianjin Xinyue Steel Group cooperated with many large contractors and EPC in Malaysia. The scope of cooperation not only includes infrastructure construction, liquid pipeline projects, but also contains some other multinational projects contracted locally. At the end of June, we were honored to cooperate with a large offshore project company in Malaysia. The product is used on water piling construction and has strict requirements on the surface of steel pipe products. According to customer requirements, the first layer is zinc epoxy primer, the second layer is a high-density epoxy, and the third layer is a polyurethane finish (white). In combination with the guidance of our technical department, we use coating with a thickness of 300 microns to meet the various performance requirements of the product. After the steel pipe has been finished completely. Our production department and quality inspection department are fully committed to control the anti-corrosion paint. We gu...

 This is an old customer from Algeria. The requirement is API 5L non-toxic epoxy resin coating inside steel pipe and 3PE coating outside, which is used for drinking water pipeline engineering. The order was decided in late July. In order to meet the delivery plan of the customer, we arranged urgent production and completed the production and testing within the specified time. The third-party inspection was completed in mid-to-late August, and the third-party recognized the quality of our drinking water pipeline and anti-corrosive quality and confirmed on the spot that the goods could be delivered.This result comes from our pursuit of product quality and our experience in quality control of water pipes. In addition, in terms of packaging service, we add extra cloth for customers to release friction, and then use steel belt to bundle, so as to prevent the damage of steel belt to the surface of anti-corrosive coating. Both ends of the pipe are equipped with plastic pipe cap and two sl...

There are many kinds of quality inspection methods for large-diameter seamless pipes, and physical methods are also the most common inspection methods. Physical inspection is a method of using some physical changes to carry out measurement or inspection. The inspection of the internal defects of raw materials or large-diameter seamless steel pipes is generally carried out by non-destructive testing. At that time, non-destructive testing included magnetic testing, ultrasonic testing, non-destructive testing, penetration testing, etc. Magnetic inspection Magnetic flaw detection can only detect the defects of the surface and near-surface layers of magnetic large-diameter seamless steel pipes, and only qualitative analysis can be made for the defects, and the characteristics and depth of the defects are only possible based on work experience. Magnetic inspection is to detect defects by using the magnetic flux leakage generated by large-diameter seamless steel pipes that are magnetized by e...
