Product Introduction

GOST-12820 and GOST-33259 are standards for steel plate flat welding flanges formulated by the Russian Standardization Organization. Both standards are applicable to pipe and valve connections. Plate type flat welding flange is a commonly used flange connection method, which is widely used in various industrial fields due to its convenient installation, high strength, and good sealing performance. The following are some basic contents of the GOST-12820/GOST-33259 standard: Size range: DN10~DN2000 Pressure rating: PN6, PN10, PN16, PN25, PN40 Material: carbon steel, stainless steel, alloy steel, etc Connection method: flat welding connection Surface treatment: cleaning, painting, or plastic spraying Scope of application: Commonly used for pipeline connection and valve connection in petroleum, chemical, natural gas, water treatment, heating and gas supply industries. GOST-12820 specifies the dimensions, materials, manufacturing processes, pressure levels, surface treatment, and inspection requirements of flanges; GOST-33259 standard specifies the dimensions and tolerances of face seals and flange connections for flat welding flanges, as well as the shape and surface quality of sealing surfaces. It is important to note that suitable flanges and gaskets are selected to ensure the safety and tightness of the connection. In addition, during installation, it is also necessary to pay attention to the symmetry of the flange and the correct tightening force to avoid problems such as leakage in the flange connection.
