Socket Weld Elbow
Socket weld elbow is mainly produced and forged by the round steel or ingot molded,and then processed to a high-pressure connection fittings which can bear highest pressure up to 9000LB.Haihao Group could produce 45 degree socket weld elbow and 90 degree socket weld elbow from the size DN6 (1/8″) to DN100 (4″).Usually the order specification is DN15 (1/2″) ~ DN100 (4″).If beyond the specifications,and we can process as customer’s drawings.
The standard of socket weld elbow contain ANSI/ASME B16.11,JIS B2316,EN 10241,etc.
The material of socket weld elbow are carbon steel,stainless steel and alloy steel,as follows:
Carbon Steel: ASTM A105,A350 LF2,etc.
Stainless Steel: ASTM A182 F304,F304L,F316,F316L,F321,F347,F310,F44,F51,etc.
Alloy Steel: ASTM A182 F1,F5,F9,F11,F22,F91,ASTM A694 F42,F46,F52,F56,F60,F65,F70,etc.
The pressure rating is 3000LB,6000LB, 9000LB.
And matching the pipe thickness grades are SCH80,SCH160,XXS accordingly.
Here are the approximate weight of 90 degree elbows and 45 degree elbows:
