Product Introduction

Weld neck flange (also known as flange neck) is a common pipe connection method, usually used in high pressure, high temperature or high vibration environment. In addition to our common basic knowledge of weld neck flanges, the following are some less common knowledge: The length of the weld neck flange is usually standard, but can be customized according to the requirements of specific applications. For example, for pipes that require the installation of thermal insulation, a longer flange neck can be provided to ensure that the insulation can completely cover the flange neck. The inside diameter of the flange neck is usually the same as the pipe inside diameter to ensure minimum resistance and best hydrodynamic performance. However, in some applications, a smaller internal diameter of the flange neck can be used to reduce the impact on fluid flow. Standard nominal diameter: DN15-DN200 Nominal pressure rating: PN10-PN25 When designing and selecting flanges, the size and location of the flange neck waist and stiffeners must be considered. These elements are very important to ensure the structural strength and rigidity of the flange. Weld neck flanges are usually used to connect two pipes or equipment of different materials or sizes. In this case, material compatibility between the flange neck and flange face must be ensured and necessary conversions made as required. When installing and disassembling neck butt welding flanges, the correct sequence and process must be followed to ensure safety and effectiveness. This includes steps such as applying lubricant correctly, tightening bolts evenly, and checking tightening torques one by one.
