A Socket Weld(SW)Tee is a T-shaped,forged pipe fitting designed to create a 90°branch or combine three pipeline ends in high-pressure/high-temperature industrial piping systems.Its defining feature is the recessed socket at each port—pipes are inserted into these sockets and sealed with a fillet weld around the rim,ensuring exceptional leak integrity without full butt-weld preparation.It is available in Equal Tee(all three ends same diameter)and Reducing Tee(branch ends smaller than the run)configurations.
Construction&Manufacturing
Made via hot forging from round bar/steel ingots,followed by precision machining,heat treatment,and non-destructive testing(NDT).
Sizes:1/8″to 4″(DN6 to DN100),standard for smaller-bore high-pressure lines.
Pressure Ratings:3000 LB,6000 LB,9000 LB(matching SCH80/XS,SCH160,XXS pipe schedules).
Materials:Carbon Steel(ASTM A105),Stainless Steel(ASTM A182 F304/F316),Alloy Steel,Super Duplex,Nickel Alloys(for corrosive media).
Key Standards:ASME B16.11,MSS SP-79/SP-83,EN 10241,BS 3799,JIS B2316.
Advantages
Strong&Leak-Tight:Fillet welds provide robust structural integrity and resistance to vibration/thermal cycling,ideal for high-pressure(up to 9000 psi)and hazardous fluid services.
Ease of Installation:No beveling of pipe ends is required;insertion into sockets ensures perfect alignment before welding,reducing on-site labor time.
Cost-Effective for Small Bores:More economical than butt-weld tees for lines≤4 inches,with comparable performance in demanding applications.
Compact Design:Saves space in dense pipe racks,common in refineries and power plants.
Applications
SW Tees are widely used in industries where safety and reliability are critical:
Oil&Gas,Petrochemical Refineries,Chemical Processing Plants
Power Generation(nuclear,thermal,combined-cycle)
Pharmaceutical&Food Processing(sanitary high-pressure lines)
Aerospace,Marine,and Offshore Platform Piping Systems
