ASTM A420 WPL6 is currently the most commonly used low-temperature steel material in the butt welding pipe market. It is an alloy steel that is resistant to low-temperature environments, which is composed of a suitable amount of one or more alloying elements added to ordinary carbon steel.ASTM A420 WPL6 material is used to manufacture seamless and straight-weld butt welding pipe fittings.

The ASTM A420/A420M standard includes four grades of materials: WPL6, WPL9, WPL3, and WPL8.The standard provides detailed requirements for the chemical composition, mechanical properties, impact properties, and impact test temperatures of these four materials.

ASTM A182 socket welding flange refers to a type of flange forged using materials such as alloys, stainless steel, or duplex stainless steel included in the ASTM A182 standard as raw materials.The connection method of socket flanges is to insert one end of the pipe into the flange ring ladder, and achieve pipe connection by welding on the pipe end and outside. There are two types: with neck and without neck.The necked pipe flange has good rigidity, small welding deformation, and good sealing performance, and can be used in applications with pressure ranging from 1.0 to 10.0 MPa.The type B flange for vessels is also a socket welding flange, used for applications with high sealing requirements.

Characteristics of ASTM A182 Welding Neck Flange Material ASTM A182 welding neck flanges are a type of flange pipe with a neck and a round steel pipe connection, which are connected to the pipe end by butt welding.It is a disk-shaped part that is most commonly used in pipeline engineering, and flang

ASTM A105 threaded flanges refer to flanges with inner holes machined into a threaded form and mated with threaded pipelines.Common ASTM A105 threaded flanges are produced according to ASEM B16.5 or EN1092-1 production standards.

ASTM A105 blind flanges are forged from carbon steel material. According to the appearance, ASTM A105 blind flanges can be generally divided into two types: blind flanges and spectacle blind flanges.
