316L stainless steel pipe welding process

February 5, 2024 No Comments

316L stainless steel pipe welding process 316L stainless steel has good resistance to chloride erosion, so it is usually used in the marine environment. Stainless steel pipe with the development of social and economic development, its application has been more and more widely popularized. For the Qinhuangdao Port Authority Oil Terminal Pipeline Laying Project using 316L stainless steel pipeline with a total length of 1630m, about 280 welded joints are equal wall thickness pipe welding, according to the welding properties of the steel to select the performance of the welding material to match the performance of the steel. In accordance with the relevant technical requirements of the welding process test and evaluation, the welding process has been successfully applied to the construction site. 1.

Beginning in the 20th century, some chemical elements that could not be used in the past began to play an important role in industry, and these chemical elements are collectively known as rare elements or rare metals. Most rare metals were discovered in the late 18th and early 19th centuries, so their industrial application was later than other commonly used metals, but many of the rare metals have long since become commonly used in modern industrial technology. Tungsten (W), molybdenum (Mo) and its alloy materials in the VI. subgroup of Mendeleev periodic system are rare metal materials with high melting point, tungsten and molybdenum are widely used in electronics, medical, glass, iron and steel metallurgy and other industries because of their unique high melting point,

how to refill gas in refrigerator KIC? To refill gas in a refrigerator, it is important to note that handling refrigerant gases can be dangerous and should be done by a qualified professional. However, I can provide you with a general overview of the process. Here are the steps involved in refilling gas in a refrigerator: Safety Precautions: Ensure that you are wearing protective gloves, goggles, and working in a well-ventilated area. Locate the Access Valve: In most refrigerators, the access valve is located at the back near the compressor. It may be covered by a plastic or metal cap. Prepare the Refrigerant: Identify the appropriate refrigerant type required for your refrigerator. The commonly used refrigerants are R-134a and R-22. Ensure that you have the

In recent years, driven by the “dual carbon” strategic goal, lightweight materials have been further developed and applied. Since the local mass production of the second-generation aluminum-silicon coated hot-formed steel Uisbor 2000 and Ductibor 1000 in 2019, the application proportion of many new models has increased year by year in just a few years. How do these two materials stand out among many lightweight materials and become the new “group pet”?Feb. 22, Hefei, China. VAMA Customer Technical Support Minister Yang Zheng shared the latest hot forming technology and lightweight application results in the industry with many automotive manufacturing experts at the AEE2023 Automotive Technology Annual Meeting, with the theme of “Introduction of the second generation of aluminum silicon coated hot forming steel products and applications”.

How to Choose A series or B series for large-diameter flanges？

January 3, 2024 No Comments

Choose A or B series for large-diameter flanges 1. A series or B series When selecting American standard flanges, if the large diameter is greater than DN600, it is necessary to consider using a large diameter flange. The selection of national standards generally follows the standard HG/T 20623-2009 . ASME is selected according to ASME B16.47-2020. It is common for designers to choose a large-diameter flange model without specifying whether the flange should be labeled as A series or B series, resulting in the purchase of the wrong flange and causing huge economic losses. Forgings are expensive, while large forgings are even more expensive. So why do large-diameter flanges need to be divided into A series or B series, and why not unify them? From the

What is Structural Steel Fabrication?

December 3, 2023 No Comments

Structural steel fabrication is the process of bending, cutting and modeling steel to create a structure. For structural steel fabrication, steel parts are often put together to create different structures of predefined sizes and shapes. It is a complex process that requires specialized knowledge, skills, and resources to complete successfully. You can refer to Jiade Group address for quality and fast solutions throughout this process. Advantages of Structural Steel Fabrication Steel is extremely durable, resistant to corrosion and must be stretched. The strength of steel is higher than its density, which makes it an excellent choice for construction and manufacturing. Structural steel usually comes to the pre-production stage and is manufactured on site. Prefabrications, the amount of work that needs to be done on the site,
