Product Introduction

The SANS 1123 standard is a steel flange standard developed by the South African National Standard, which is applicable to pipe connections for some liquids, gases, steam, and other fluids. This standard specifies the dimensions, materials, manufacturing process, pressure rating, surface treatment, and inspection requirements of neck welded flanges.

The following is some basic information about the SANS 1123 standard neck butt weld flange:

Size range: DN10~DN6000
Pressure rating: 600kPa, 1000kPa, 1600kPa, 2500kPa, 4000kPa
Material: carbon steel, stainless steel, alloy steel, etc
Connection method: butt welding connection
Surface treatment: cleaning, painting, or plastic spraying
Scope of application: Commonly used for pipeline connection in petroleum, chemical, natural gas, water treatment, heating and gas supply industries.

It should be noted that the pressure rating specified in SANS 1123 refers to the nominal pressure of the flange, not the maximum working pressure of the pipe. Therefore, when using, it is necessary to select the corresponding pressure grade and material grade of the neck butt welding flange according to the actual working pressure to ensure the safety and reliability of the connection.

In the standard of SANS1123, welding neck flange, slip on flange, blind flange, threaded flange, and lap joint flange are all applicable to this standard, but they vary in specific application environments. Therefore, when selecting flanges under this standard, please pay attention to careful selection.
