1.1 Definition and Purpose
At YANHAO, we understand that 14″ pipe flanges are essential components in various industrial applications. These flanges serve as connectors, allowing for the secure and leak-free connection of pipes, valves, and equipment. They play a pivotal role in ensuring the smooth and efficient operation of fluid systems.

1.2 Common Materials and Standards
When it comes to 14″ pipe flanges, YANHAO prioritizes the use of high-quality materials. We offer flanges made from various materials, including carbon steel, stainless steel, and alloy steel. Each material is carefully selected to align with the specific demands of your application. Our flanges adhere to industry standards such as ANSI/ASME B16.5, ensuring compatibility and reliability.

1.3 Industry Applications
YANHAO’s 14″ pipe flanges find widespread use across various industries. In the oil and gas sector, they withstand the rigorous demands of high-pressure pipelines. In chemical processing, our flanges resist corrosive chemicals, maintaining system integrity. Power generation relies on them for efficient energy production, while water and wastewater treatment facilities trust our flanges for reliable water management. These flanges also have applications in construction, marine, food and beverage, and more.

2. Types of 14″ Pipe Flanges

2.1 Weld Neck Flange
YANHAO’s weld neck flanges feature a tapered hub that ensures a robust structural connection. They are meticulously welded to the pipe, guaranteeing a reliable and durable joint. These flanges are a preferred choice for high-pressure and high-temperature applications, where safety and performance are paramount.

2.2 Slip-On Flange
Our slip-on flanges are designed with a flat face and a slightly larger bore, allowing them to slip effortlessly over the pipe and then be welded securely in place. These flanges are ideal for low-pressure applications, offering ease of assembly and disassembly, making maintenance hassle-free.

2.3 Blind Flange
YANHAO’s blind flanges serve as solid disks with no bore, effectively sealing off the end of pipes, vessels, or valves. These flanges are crucial for pressure testing systems and instances where the isolation of a pipeline section is necessary for maintenance or safety.

2.4 Lap Joint Flange
Our lap joint flanges consist of two components: a stub end and a backing flange. The stub end is welded to the pipe, while the backing flange can rotate freely. This design is perfect for systems that require frequent dismantling and realignment, ensuring efficiency and adaptability.

2.5 Socket Weld Flange
YANHAO’s socket weld flanges incorporate a recessed area where the pipe is inserted and then fillet-welded around the perimeter. These flanges offer a smooth bore and exceptional structural integrity, making them suitable for small-bore, high-pressure pipelines.

2.6 Threaded Flange
Threaded flanges feature threads on their inner bore, allowing them to be conveniently screwed onto the pipe. YANHAO recommends these flanges for plumbing systems, small-diameter pipelines, and applications where ease of disassembly is critical.

Each type of 14″ pipe flange from YANHAO is meticulously crafted to meet the unique demands of various applications, delivering on our promise of reliability and performance.

3. Key Considerations for 14″ Pipe Flange Selection

3.1 Material Selection
At YANHAO, we recognize that material selection is a critical factor in ensuring the longevity and performance of 14″ pipe flanges. We offer a range of materials, each carefully chosen to suit specific applications. Carbon steel provides strength and durability, while stainless steel offers corrosion resistance. Alloy steel is an excellent choice for applications with high-temperature and pressure requirements. We also have expertise in handling exotic materials like titanium and Hastelloy for specialized needs.

3.2 Pressure and Temperature Ratings
Choosing the right pressure and temperature ratings for your 14″ pipe flanges is essential to prevent leaks and system failures. YANHAO provides detailed guidance on determining the required ratings based on your system’s working conditions. Our expert recommendations ensure that the selected flanges can withstand the specified pressure and temperature ranges, ensuring safety and reliability.

3.3 Flange Face Finish
Flange face finish plays a pivotal role in achieving a secure seal and preventing leaks. YANHAO offers various flange face finishes, including raised face, flat face, and ring-type joint facing. We guide you in selecting the most suitable finish for your application to ensure a perfect fit and leak-free connection.

3.4 Bolt Hole Patterns
The bolt hole pattern of your 14″ pipe flanges is crucial for proper alignment and assembly. YANHAO adheres to standard bolt hole patterns such as ANSI/ASME B16.5, API, and DIN, ensuring compatibility with industry norms. However, we also understand that unique projects may require custom bolt hole patterns, and we have the capability to accommodate such specific needs while maintaining structural integrity.

3.5 Gasket Selection
Gaskets are an integral part of ensuring a leak-free connection with 14″ pipe flanges. YANHAO provides guidance on selecting the right gasket material, taking into account factors such as fluid compatibility, temperature, and pressure. We offer a variety of gasket types, including full-face gaskets and ring gaskets, to suit different applications and sealing requirements.

At YANHAO, we are dedicated to helping you make informed decisions during the selection process, ensuring that your 14″ pipe flanges meet the highest standards of performance, safety, and reliability.
