Congratulations, Haokun flanges Co., Ltd. received the order for blind flange of CNOOC COOEC offshore oil project today
I wish Haokun flanges Co., Ltd. received the order for blind flange of CNOOC COOEC offshore oil project today,
10000psi WN-RTJ XXS A182 F51 API 6A Type 6BX
Flange 1-13/16"×2" WN-RTJ SCH80 10000PSI A105 API 6A Type 6BX
After half a year's quotation and technical discussion, the blind flange has finally made some achievements. The cooperation with CNOOC COOEC this time is attributed to Haokun flange's blind flange, which obtained API 6A certificate from American Petroleum Association in 2011. APL abbreviation of American Petroleum Institute one of the earliest and most successful standard setting chambers of Commerce in the world Enterprises with APL Monogram: indicate that the manufacturer guarantees that the confirmed products meet the API specifications at the time of manufacture
API acknowledges that the manufacturer has been trusted by API in complying with the established API standards. The API Monogram is the product mark of the American Petroleum Institute. Its purpose is to identify the production equipment and materials and provide manufacturers that can meet the API quality system and product standards. The blind flange produced by Shanxi Haokun flanges Group Co., Ltd. complies with API 6A standard.During the continuous certification of blind flange in recent years, Haokun flanges has been highly recognized by API Association and obtained the certification of APL 6a PSL3, which is the highest level of APL certification. It was with the approval of the American Petroleum Association that Haokun flanges won the order of CNOOC for blind flange:
10000psi WN-RTJ XXS A182 F51 API 6A Type 6BX
Flange 1-13/16"×2" WN-RTJ SCH80 10000PSI A105 API 6A Type 6BX
Next, Haokun flanges will go all out and try its best to complete the production of blind flange and deliver qualified blind flange products: 10000psi WN-RTJ XXS A182 F51 API 6A Type 6BX
Flange 1-13/16"×2" WN-RTJ SCH80 10000PSI A105 API 6A Type 6BX.
Heat treatment of Socket Welding Flanges
Heat treatment is one of the important processes in the production of Socket Welding Flanges. Compared with other processing processes, heat treatment generally does not change the shape and overall chemical composition of the workpiece, but makes the Socket Welding Flanges have its unique chemical properties by changing the internal metallographic structure of the Socket Welding Flanges or changing the chemical composition of the Socket Welding Flanges. As we all know, the heat treatment of Socket Welding Flanges is divided into quenching, tempering, annealing and other processes. Then the most important thing in the quenching of Socket Welding Flanges is to select the appropriate quenching oil. The most important thing in the tempering of Socket Welding Flanges is to grasp the medium, and the most important thing in annealing is to grasp the temperature. What is quenching oil in heat treatment of Socket Welding Flanges? How to choose? The quenching oil used in the heat treatment of Socket Welding Flanges is essentially a kind of lubricating oil. Although it is only a kind of lubricating oil, the quenching oil in the heat treatment of Socket Welding Flanges must be selected correctly. If it is not selected properly, it will cause many problems in the heat treatment of Socket Welding Flanges and affect the chemical properties of socket flange after heat treatment. The selection of quenching oil for Socket Welding Flanges needs to be considered. The raw materials of Socket Welding Flanges mainly consider the chemical properties of raw materials, installation distance, weight, pressure bearing condition, oil used, flow rate of medium, etc. these need to be considered according to the actual use of each Socket Welding Flanges, rather than the general choice, which has a great impact on the chemical properties, It may cause unqualified products of Socket Welding Flanges.
Selection of water-based quenching oil for heat treatment of Lapped Joint Flanges
The quenching process in the heat treatment of Lapped Joint Flanges is divided into induction quenching and immersion quenching. In both ways, water-based quenching oil will affect the cooling speed of Lapped Joint Flanges after heat treatment. Therefore, the selection of appropriate water-based quenching machine is particularly important for the heat treatment of Lapped Joint Flanges. It is necessary to study the physical properties of each water-based quenching oil and the influence of its concentration ratio on the cooling rate of Lapped Joint Flanges after heat treatment. In addition, the purity and concentration shall be maintained. During the heat treatment of the Lapped Joint Flanges, its concentration shall be tested regularly to ensure the heat dissipation capacity. Check the pH value to ensure the corrosion resistance of the Lapped Joint Flanges after heat treatment. Check the pollution (hydraulic oil, etc.) that may adversely affect the cooling of Lapped Joint Flanges after heat treatment and may affect its metallurgical properties. Check for microorganisms that may contaminate the water-based quenchant. These microorganisms will produce unpleasant odor in the quenching tank and working environment. Affect the safety and working environment of workers in the Lapped Joint Flanges heat treatment workshop. Depending on the situation, if necessary, the heat treatment of Lapped Joint Flanges shall use biological stable water-based quenchant. Moreover, as the supplier of Lapped Joint Flanges, the operation in heat treatment is extremely important. Shanxi Haokun flanges Group Co., Ltd. will actively implement the social responsibility as Lapped Joint Flanges and take the initiative to maintain in advance to ensure that the chemical properties of Lapped Joint Flanges purchased by customers meet the standards and requirements. To provide customers with efficient and high-quality Lapped Joint Flanges products.
