A ring joint flange is a type of flange that uses a metal ring to create a leak-proof seal between two pipes. The metal ring is placed in a groove on the face of the flange and is compressed when the bolts are tightened. This compression creates a tight seal that prevents the flow of fluids or gases between the pipes. Material: Carbon Steel, stainless steel, nickel alloy Size: 1" to 24" Pressure rating: 150# to 2500# Class: ANSI Class 150, 300, 600, 900, 1500, 2500 Standard: ANSI B16.5, API 6A, DIN EN 1092-1 Ring joint flanges are a reliable and effective way to create a leak-proof seal. They are used in a variety of applications where a high level of safety and reliability is required.

ASME B16.5 flanges are a set of American Society of Mechanical Engineers (ASME) standards that define the dimensions, materials, and tolerances for pipe flanges and flanged fittings. The standard covers flanges made from cast or forged materials, and blind flanges and certain reducing flanges made from cast, forged, or plate materials. It also includes requirements and recommendations regarding flange bolting, flange gaskets, and flange joints. The ASME B16.5 standard is used in conjunction with other ASME standards, such as the Boiler and Pressure Vessel Code and the B31 Piping Codes. It is also widely accepted in other countries, and is often referred to as the ANSI B16.5 standard. The ASME B16.5 standard defines six types of flanges: Weld neck flanges Slip-on flanges Socket weld flanges Threaded flanges Lap joint flanges Blind flanges Reducing flanges Each type of flange has different dimensions and requirements. For example, weld neck flanges have a neck that is welded to the pipe, while slip-on flanges are simply slipped over the pipe. The ASME B16.5 standard is an important reference standard for the design, construction, and installation of piping systems. It ensures that flanges and flanged fittings are safe and reliable, and that they can withstand the pressures and temperatures of the application. Here are some of the key features of ASME B16.5 flanges: We have available in a variety of materials, including carbon steel, stainless steel, and alloy steel. We have a variety of pressure-temperature ratings, from 150 psi to 2500 psi. We have available in a variety of flange types, to suit different applications.

ASME B16.47 is an American Society of Mechanical Engineers (ASME) standard that specifies the dimensions, materials, and tolerances for large diameter steel pipe flanges. The standard covers flanges with nominal pipe sizes (NPS) from 26 to 60 and pressure class ratings from 75 to 900. ASME B16.47 flanges are divided into two series: Series A and Series B. Series A flanges are based on the MSS SP-44 standard, while Series B flanges are based on the API 605 standard. The main difference between the two series is that Series A flanges have a larger bolt circle diameter than Series B flanges. ASME B16.47 flanges are typically used in high-pressure and high-temperature applications, such as in the oil and gas industry. They are also used in other industries, such as the chemical, power, and water treatment industries. Here are some of the key features of ASME B16.47 flanges: They are made of steel, cast iron, or stainless steel. They have a raised or flat face. They have a bolt circle diameter that ranges from 125 to 600 millimetres. They have a pressure class rating that ranges from 75 to 900. They have a thickness that ranges from 6.3 to 127 millimetres. ASME B16.47 flanges are an important part of many piping systems. They help to ensure the safe and reliable operation of these systems.

A line blank is a pressure-retaining plate that is used to block off a section of pipe. It is typically made of steel or cast iron and has a variety of features, including a raised face, flat face, or grooved face. The ASME B16.48 standard specifies the dimensions, tolerances, materials, and markings for line blanks. There are two main types of line blanks: Spectacle blind flanges: These have a solid end and an open end connected by a web or tie bar. Paddle blanks: These are similar to the solid end of a spectacle blind flange, but they have a plain radial handle. Line blanks are used in a variety of applications, including: To isolate a section of pipe for maintenance or repair To prevent the flow of fluid in a pipe To provide a test point for a piping system The ASME B16.48 standard is an important specification for the design and manufacture of line blanks. It ensures that line blanks are safe and reliable, and that they meet the requirements of the applicable codes and regulations.

An ASME B16.36 flange is an orifice flange, which is a type of flange used for measuring the flow rate of fluids in a pipeline.

A high hub flange is a type of blind flange that has a larger hub than a standard blind flange. The hub is the central portion of the flange that is used to connect it to a pipe or other fitting. The larger hub provides a more secure connection and also helps to distribute the load more evenly. High hub flanges are typically used in applications where there is a high pressure or temperature, or where a secure connection is critical. They are also used in applications where the flange needs to be able to withstand a lot of vibration or movement. The technical specifications of high hub flanges vary depending on the material, size, and class. However, some common specifications include: Material: Carbon steel, stainless steel, alloy steel, nickel alloy, titanium Size: 1/2" to 120" nominal bore Class: 150, 300, 600, 900, 1500, 2500 Hub height: 1" to 4" Bolt pattern: ANSI B16.5 or ASME B16.47 High hub flanges are typically manufactured to meet the following standards: ANSI B16.5: American National Standards Institute standard for flanges and flanged fittings ASME B16.47: American Society of Mechanical Engineers standard for blind flanges High hub flanges can be purchased from a variety of suppliers. When selecting high hub flanges, it is important to consider the following factors: Material: The material of the flange should be compatible with the material of the pipe or fitting that it will be connected to.
