Socket welded stainless steel elbow is a type of stainless steel pipe fitting connected by socket welding. It is mainly used in pipeline systems to achieve angular turning and has the advantages of high connection strength, corrosion resistance and high pressure resistance.
The specifications of socket-type welded stainless steel elbows are mainly divided into two categories: standard specifications and custom specifications . The following is a detailed description:
Standard specification
Common specification
Diameter range : DN15-DN50 (nominal diameter).
Pressure rating : 3000LB, 6000LB, 9000LB or SCH80, SCH160, XXS.
Angle types : 45°, 90°, 180° (commonly used), 60° and other non-standard angles can be customized.
Material and standard
Stainless steel grades : 304, 304L, 316, 316L, etc.
Execution standard :
National standards: GB/T14383-93, GB/T14383-2008.
American standard: ASME B16.11.
Petrochemical standard: SH3410.
Chemical industry standard: HG/T21634.
Beyond standard range
Diameter : DN6-DN100 (customization required).
Pressure rating : special grades such as SCH80, SCH160, XXS, etc.
Angle : 60° and other non-standard angles.
Special requirements
Surface treatment : polishing, galvanizing, etc.
