Product Introduction

Flange products, as critical components for connecting pipes and equipment, play a pivotal role in the industrial sector. Widely used across multiple industries—including petroleum, chemical processing, power generation, shipbuilding, and metallurgy—they not only facilitate the transportation and distribution of media but also ensure the safe and stable operation of entire systems. With continuous advancements in industrial technology, flange products have become increasingly diverse in both type and specification—ranging from basic flat-face flanges to high-pressure self-tightening flanges, each designed to fulfill specific functions and tasks. This article will delve into the fundamental structure, classification, selection principles, and the vital importance of flange products in industrial applications. High-neck flange is a widely used pipe connection component designed for high-pressure and high-temperature applications. Its long tapered neck provides excellent stress distribution, strong welding performance, and reliable sealing, making it suitable for oil, gas, chemical, and power industries.
