Socket Welded Flange

As the professional manufacturer, SN Valve would like to provide you high quality socket welded flange. Socket weld flange is a flange in which the end of the pipe is inserted into the step of the flange ring and welded at the end and outside of the pipe. It usually consists of flange body, bolt holes, sealing surface and other parts, and its structural form has two kinds of necked and non-necked. Necked socket weld flanges have good rigidity, small welding deformation and better sealing, so they are more common in practical applications.

The Advantages of Duplex Steel Flanges: Why They Outperform Standard Stainless Steel Flanges
Wenzhou Shuangneng Valve Co., Ltd. specializes in manufacturing corrosion-resistant stainless steel, duplex steel, and specialty alloy flanges, pipe fittings, and custom components for 20+ years. Compliant with ASME, DIN, JIS, and GB standards, we offer OEM solutions with MOQ 1 unit. Ideal for harsh environments in oil/gas, chemical, and marine industries.
What is a Tube Sheet and Why is It Essential in Heat Exchangers and Other Industrial Applications?
A Tube Sheet is a critical component used in heat exchangers, pressure vessels, and other industrial systems. It is a flat plate that features a series of holes or perforations designed to accommodate tubes or pipes. The tubes are inserted into these holes, and the Tube Sheet serves as a structural support, ensuring that the tubes remain securely in place while allowing for fluid or heat transfer between the different sections of the system. Tube Sheets are typically made from materials such as stainless steel or other corrosion-resistant alloys due to their durability and resistance to harsh operating conditions.
Socket welding cross has attracted widespread attention and application
Recently, a new design has been developed for a commonly used pipe fitting in the field of pipeline connection, Socket Welding Cross.
Importance of tube sheet anti-corrosion and how to prevent corrosion?
Tube sheets are mainly used in chemical containers, such as shell-and-tube heat exchangers and seawater desalination, to support and fix the tubes. The metal material makes it not only very rigid, but also has great thermal conductivity. In its use, tube sheet anti-corrosion is a very important task. Why is this?
Stainless steel pipe fittings production process 1: Hot rolling and cold drawing processes
The production process of stainless steel pipe fittings is complex and precise, and ensuring that each process meets high-quality standards is key. The following is the hot rolling and cold drawing production process of stainless steel pipe fittings.
Preventing Chloride Stress Corrosion: Why 316L Stainless Steel Flanges Outperform Carbon Steel in Coastal Plants
In 2023, Wenzhou Shuangneng Valve Co., Ltd. helped an Indonesian power plant replace carbon steel flanges with 316L stainless steel, reducing chloride-induced failures by 40% within 12 months. Coastal salt spray and humidity accelerated corrosion in carbon steel, while 316L’s molybdenum-rich alloy prevented stress cracking.
