ASTM A105 threaded flanges refer to flanges with inner holes machined into a threaded form and mated with threaded pipes. It is a non-welded flange.Compared to other types of flanges, its advantage is that it does not require welding, and the additional torque on the cylinder or pipe caused by flange deformation is minimal.At the same time, threaded flanges are characterized by ease of installation and maintenance and can be used on some pipelines that do not allow welding.However, under conditions of rapid temperature changes in the pipeline or temperatures above 260°C and below -45°C, it is recommended not to use threaded flanges to avoid leaks.
Dimensions of ASTM A105 Threaded Flanges
Common ASTM A105 threaded flanges are produced according to ASEM B16.5 or EN1092-1 production standards.ASEM B16.5 is the American standard production standard, and EN1092-1 is the European standard production standard.These two standards have slightly different requirements for flange dimensions.
Characteristics of ASTM A105 Material
ASTM A105 is an American material standard, where A105 represents the material specification of flanges, namely carbon steel materials.During the manufacturing process, the ASTM A105 standard has strict requirements for the chemical composition, mechanical properties, corrosion resistance, etc. of the material.Therefore, it is widely applicable in various industrial applications.
