SOCKOLET

Sockolet is a specific type of branch connection fitting used to provide an outlet from a larger pipe to a smaller one through socket welding. It allows for a smooth and efficient transition between the main pipe and the branch, maintaining structural integrity and fluid flow.

Sockolet is a kind of pipe fittings. This pipe fittings is used for 90 degree self-reinforcing branch accessory, and is suitable for small instrument connection or small branch pipe. It has the same basic design as “weldolet” or “threadolet”, but its branch connection is socket weld type.
 


The sockolet pipe fittings has full size or reduced size. Full size means to take a branch of same size as the pipe, for example, 3 inch to 3 inch. Reducing size is when the branch size is less than the running pipe size, for example, 3 inche to 1inch.


The sockolet pipe fittings is classified as socket weld fitting, and are available in class 3000,6000 and 9000 pressure temperature rating.

Differences between Weldolet pipe fittings, Sockolet pipe fittings, Threadolet pipe fittings

The mainly differences are the connection surface, weldolet ends in plain or beveled to weld on the the branch pipe, sockolet ends in socket type that to insert branch pipe. Threadolet is insert branch pipe and with screw connection. So they have different advantages:

Weldolet: Compatible with higher pressure and simple connection, cost lower. Thickness in SCH STD, SCH XS, SCH 160 to SCH XXS.
Sockolet: Compatible with higher pressure but cost is higher. Pressure ratings in 3000#, 6000#.
Threadolet: Easy to replace and maintain, cost is higher. Pressure ratings in 3000#, 6000#.
