Flange Types: A Comprehensive Portfolio for Every Application 

BEIJING SINOWORLD offers an extensive array of flange types, each designed to serve specific functions and meet the unique demands of different industrial applications.

Weld Neck Flanges

Weld neck flanges are one of the most popular types in the company's portfolio. These flanges feature a long tapered hub that is butt - welded to the pipe. This design provides excellent stress distribution, making them ideal for high - pressure, high - temperature, and high - vibration applications, such as in the oil and gas, petrochemical, and power generation industries. The seamless connection between the flange and the pipe ensures maximum strength and leak - proof performance.

Slip - On Flanges

Slip - on flanges are designed to slide over the end of the pipe and are then fillet - welded on both the inside and outside. They are relatively easy to install, which makes them a cost - effective option for low - pressure applications and situations where quick installation is required. Commonly used in water supply systems, general plumbing, and some light - industrial applications, these flanges provide a reliable connection while being more budget - friendly.

Blind Flanges

Blind flanges have no hole in the center and are used to close the end of a pipe. They are crucial for testing pipelines, isolating sections of a system for maintenance, or for future expansion. Made from high - quality steel materials, BEIJING SINOWORLD's blind flanges can withstand high pressures and are suitable for use in demanding industrial environments.

Threaded Flanges

Threaded flanges feature internal threads that match the external threads of the pipe. This type of flange is easy to install without the need for welding, making it suitable for applications where welding is not feasible or preferred, such as in some small - scale plumbing projects or in areas where fire hazards are a concern. However, they are generally limited to lower - pressure applications due to the potential for leakage at the threaded joints under high pressure.

Flange: Ensuring Secure and Reliable Pipe Connections 

A flange is a crucial component in piping systems, providing a means of connecting pipes, valves, pumps, and other equipment, while also allowing for easy disassembly and maintenance. BEIJING SINOWORLD's flanges are engineered with precision to ensure secure and reliable connections in a wide range of applications.

The company's flanges are manufactured using advanced techniques and high - grade raw materials. Each flange undergoes rigorous quality control processes, including dimensional inspections, material testing, and pressure testing. This ensures that the flanges meet or exceed international standards, such as ASME, ANSI, and DIN.

For example, in a large - scale petrochemical project, the integrity of the piping system is of utmost importance. BEIJING SINOWORLD's weld neck flanges, with their superior strength and leak - proof design, play a vital role in maintaining the safety and efficiency of the system. The company's commitment to quality ensures that the flanges can withstand the harsh operating conditions, including high pressures, extreme temperatures, and corrosive environments commonly found in such industries.

Moreover, BEIJING SINOWORLD's flanges are designed to be compatible with a variety of pipe materials, including carbon steel, stainless steel, and galvanized pipes. This versatility makes them suitable for use in different projects, whether it's a new construction or a system upgrade.

FAQs About Flanges 

How do I choose the right flange type for my project? 

The choice of flange type depends on several factors. Consider the application's pressure and temperature requirements. For high - pressure and high - temperature situations, weld neck flanges are a good choice. If installation ease and cost - effectiveness are priorities for low - pressure applications, slip - on flanges may be suitable. Blind flanges are used for closing pipe ends, and threaded flanges are ideal when welding is not an option. You can also consult BEIJING SINOWORLD's experts for personalized advice based on your specific project needs.

What is the impact of material on flange price? 

The material of the flange significantly affects its price. Stainless steel flanges are generally more expensive than carbon steel flanges due to the higher cost of raw materials and manufacturing processes. Alloy steel flanges, which offer enhanced properties such as corrosion resistance and high - temperature strength, are also priced higher. However, the choice of material should be based on the application requirements to ensure the flange's performance and durability.

Does BEIJING SINOWORLD provide installation guidance for its flanges? 

Yes, the company provides comprehensive installation guidance for its flanges. This includes detailed installation manuals and on - site technical support if required.
