For a flange where the pipe end is inserted into the socket and secured by an external fillet weld, the inner bore forms a relatively smooth flow path. It is primarily used for small-diameter, high-pressure pipelines; a specified clearance must be maintained between the pipe end and the bottom of the socket during installation.

Standards: GB/T 9124.1-2019 (PN series) or GB/T 9124.2-2019 (Class series); export projects may comply with ASME B16.5-2025.
Structure: Socket Weld (SW) flange; orders must match the pipe’s outside diameter and wall thickness, and verify the socket bore depth.
Size Range: The ASME B16.5 standard generally covers NPS 1/2–24; Class 2500 flanges apply up to NPS 12. Specific flange types do not necessarily cover all size-pressure combinations; refer to the corresponding dimensional tables.
Pression Évaluations : Classe 150, 300, 400, 600, 900, 1 500, 2 500, ou sélectionnées selon la série PN correspondante ; les valeurs nominales pression-température admissibles varient en fonction du groupe de matériaux et de la température de fonctionnement.
Materials/Facing: Common materials include ASTM A105, A182 F304/F316, etc.; facing types (RF, FF, RTJ, etc.) must be confirmed as a complete set alongside gaskets, bolts, and mating flanges.
Ordering/Acceptance: Confirm flange type, DN/NPS, PN/Class, material group, facing type, pipe wall thickness/bore, and bolting/gasket systems; verify against the corresponding standard dimensional tables item by item—availability of all combinations cannot be assumed based solely on the standard’s overall scope.
