ASME B16.5 Carbon Stainless Steel Welding Neck Flange

Product Introduction

ASME B16.5 is a standard issued by the American Society of Mechanical Engineers (ASME), covering the specifications for butt welded flanges.

Size

ASME B16.5 neck welded flanges have a wide range of sizes, including nominal diameters ranging from 1/2 inch to 24 inch (15mm to 600mm). There are detailed regulations on the diameter, number and diameter of screw holes, as well as the layout of screw holes

Pressure level

The standard defines flanges with different pressure ratings, including 150, 300, 600, 900, 1500, and 2500 pound ratings. These levels represent the flange's ability to withstand pressure.

Material

ASME B16.5 specifies various materials for neck welded flanges, including carbon steel, alloy steel, stainless steel, etc. The selection of materials usually depends on the working environment, medium, and temperature and pressure conditions.

Sealing surface

Neck welded flanges usually have flat sealing surfaces for good contact with the sealing gasket connected to the flange. This ensures the sealing performance of the pipeline system.

International standards

ASME B16.5 is an American standard, but due to its widespread application, it has been accepted and adopted by many countries and regions.
for flanges.

Advantages and disadvantages

Advantages:

1.Good sealing performance.
2.High temperature and high pressure resistance.
3.Widely used in various industrial fields, especially in the chemical, petroleum, natural gas, and power industries.

Disadvantages:

1.The manufacturing cost is relatively high.
2.Installation and maintenance require professional skills.

Application scope

Neck welded flanges are widely used in various pipeline systems, especially in high temperature, high pressure, and high sealing performance requirements. Commonly found in industries such as chemical, petroleum, natural gas, and electricity.

Overall, ASME B16.5 neck welded flange is a high standard and high-performance flange connection component suitable for strict industrial environments. When selecting and using, careful consideration should be given to specific engineering requirements and environmental conditions.
