Understanding Flange Pressure Ratings Flange pressure rating indicates the maximum pressure a flange can safely withstand at a specific temperature. Selecting the correct rating is critical for system safety and compliance. ASME Pressure Classes Class Max Pressure (bar) Max Pressure (psi) Typical Applications Class 150 19.6 285 Low pressure water, air, general service Class 300 […]

Обзор резьбовых фланцев Резьбовой фланец соединяется с трубами с помощью внутренней резьбы, исключая необходимость сварки. Это делает резьбовые фланцы идеальными для применения в тех случаях, когда сварка нецелесообразна или требуется быстрый монтаж и демонтаж. Характеристики конструкции Внутренняя резьба соответствует внешней резьбе трубы (NPT или BSP) Для монтажа не требуется сварка Конические резьбы создают [...].

Flange Standards Overview Flange design, manufacturing, and inspection must follow strict international and national standards. Understanding different standard systems is crucial for proper flange selection. ASME Standards (American) ASME B16.5: NPS 1/2 to 24 Pressure Classes: 150, 300, 600, 900, 1500, 2500 Face Types: RF, FF, RTJ, MFM EN Standards (European) EN 1092-1: Main European […]

Function and Purpose A Blind Flange is a solid flange without a center opening, used to close off the end of pipes, valves, or pressure vessels. It serves as a terminal closure component, playing a critical role during maintenance, inspection, or system expansion. Main Applications Pipe Closure: Seal pipe ends to prevent medium leakage System […]

What is a Weld Neck Flange A Weld Neck Flange features a long tapered hub that is butt-welded to the pipe. It is the most commonly used flange type for high pressure, high temperature, and low temperature applications. Key Advantages Superior stress distribution with tapered hub design High strength connection comparable to pipe itself Handles […]

Flange Basics A flange is one of the most critical connection components in industrial piping systems, used to connect pipes, valves, pumps, and other equipment. Main Functions Connection: Reliably join pipe sections Sealing: Work with gaskets Maintenance: Removable design Flexibility: Direction changes Common Types Weld Neck: High pressure and temperature Slip On: Easy installation, lower […]
