Features of 5″ Pipe Flange

Material Composition

YANHAO’s 5″ pipe flanges are available in a variety of materials to suit different application needs. Carbon steel flanges provide strength and durability, making them suitable for most general-purpose applications. Stainless steel flanges offer excellent corrosion resistance, making them ideal for industries with high humidity, chemical exposure, or where sanitation is critical. Alloy steel flanges are preferred in high-temperature and high-pressure situations due to their superior strength and resistance to deformation.

Dimensions and Specifications

YANHAO’s 5″ pipe flanges are manufactured to precise dimensions and specifications. They comply with industry standards such as ASME/ANSI B16.5 and DIN, ensuring compatibility and ease of installation. The dimensions include the outer diameter, inner diameter, bolt hole diameter, and flange thickness, all designed to fit seamlessly with 5″ pipes.

Corrosion Resistance

YANHAO understands that corrosion can significantly impact the performance and lifespan of a pipe flange. That’s why our 5″ flanges undergo surface treatments such as zinc coating, epoxy coating, or galvanization to enhance corrosion resistance. In addition, we offer flanges made from materials with inherent corrosion resistance capabilities, such as stainless steel or alloy steel, to further protect against corrosive environments.

Pressure Rating

YANHAO’s 5″ pipe flanges are engineered to withstand different pressure ratings, ensuring the safety and integrity of the piping system. The pressure rating indicates the maximum pressure that the flange can handle without failure. Our flanges are designed and tested to meet the requirements of various pressure classes, such as Class 150, Class 300, Class 600, and more, ensuring reliable performance in demanding applications.

Temperature Range

YANHAO’s 5″ pipe flanges are designed to operate effectively within a wide temperature range. The selected materials are capable of withstanding both high and low temperatures without compromising performance. This ensures that the flanges maintain their structural integrity, prevent leakage, and avoid any detrimental effects caused by temperature fluctuations.

Fastening Mechanisms

YANHAO’s 5″ pipe flanges feature reliable and secure fastening mechanisms. The flanges are equipped with bolt holes or through-holes that align with the holes on the pipes, allowing for easy installation and ensuring a secure connection. The fasteners, including bolts and nuts, are made from high-strength materials and undergo strict quality control to ensure proper and secure fastening.

Compliant Standards

YANHAO’s 5″ pipe flanges meet industry standards such as ASME/ANSI, DIN, EN, and JIS. These flanges undergo stringent testing and inspection processes to ensure compliance with quality control standards. By adhering to these standards, YANHAO ensures that its flanges meet the necessary requirements for reliability, safety, and compatibility in various applications and industries. YANHAO’s 5″ pipe flanges are designed with a meticulous focus on material composition, precise dimensions, corrosion resistance, pressure ratings, temperature range, secure fastening mechanisms, and compliance with international standards. These features make YANHAO flanges a reliable and long-lasting choice for customers seeking high-performance solutions for their piping systems.

Types of 5″ Pipe Flanges

There are several types of 5″ pipe flanges available in the market. Here are some common types:

Slip-On Flange (SO)

  • This type of flange has a slightly larger diameter than the pipe it is being used with.
  • It is slipped over the pipe and then welded in place.
  • These flanges are simple to align and install, making them popular for low-pressure applications.

Weld Neck Flange (WN)

  • This flange has a tapered neck and is designed to be welded to the pipe.
  • It provides high strength and rigidity to the joint.
  • Weld neck flanges are preferred for high-pressure and high-temperature applications.

Blind Flange (BL)

  • A blind flange is used to close off the end of a pipe.
  • It has no opening, hence the name “blind.”
  • Blind flanges are commonly used when the end of a pipe needs to be closed temporarily or permanently.

Threaded Flange (TH)

  • This type of flange has internal threads that allow it to be screwed onto a pipe with external threads.
  • Threaded flanges are widely used in low-pressure applications and where welding is not preferred.

Socket Weld Flange (SW)

  • Similar to slip-on flanges, socket weld flanges have a smaller diameter than the pipe.
  • The pipe is inserted into the socket of the flange, and then fillet welded on the outside.
  • These flanges provide good strength and are suitable for small pipe sizes and high-pressure applications.

Lap Joint Flange (LJ)

  • A lap joint flange consists of two parts: a stub end and a loose backing flange.
  • The stub end is either welded or lap jointed to the pipe while the backing flange is not.
  • It allows for easy alignment of bolt holes and is often used in systems requiring frequent dismantling.

Orifice Flange (OF)

  • Orifice flanges are specifically designed for flow measurement or restriction applications.
  • They have provision for installing orifice plates, which help control the flow rate within the pipe.

These are just some of the commonly used types of 5″ pipe flanges. Each type has specific advantages and applications based on factors such as pressure, temperature, and installation requirements. It is important to select the appropriate flange type based on the specific needs of your piping system.
