ASTM A105 Socket Weld Outlet

What is the Socket Weld Outlet

ASTM A105 socket weld outlet is used for 90 degree self-reinforcing branch fittings, and is suitable for small instrument connection or small branch pipe. It has the same basic design as butt weld outlet or threaded outlet , but its branch connection is socket weld type.

Socket outlet 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.

One end of the socketolet is flat, inserted into the branch pipe, and then fillet welded together. ASTM A105 socket weld outlet is classified as socket weld fitting, and are available in class 3000 and 6000 pressure rating.

Specification of ASTM A105 Socket Weld Outlet

Product Features for Socket Weld Outlet

Compatible with higher pressure but cost is higher.

Pressure ratings in 3000LB, 6000LB.

ASTM A105 sock weld outlet has bevelled ends to simplify the welding process.

ASTM A105 socket weld outlet has higher tensile strength, firmness, corrosion resistance, higher durability, excellent weld ability and longer service life.

Differences between Weldolet, Sockolet, Threadolet.

Socket Weld Outlet

Butt Weld Outlet

Threaded Outlet

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#.

Material for ASTM A105

ASTM A105 and ASME SA105 covers seamless forged carbon steel piping components for use in pressure systems at ambient and high-temperature service.

Flanges, fittings, valves and various other parts ordered to customer dimension or to industry standards such as MSS, ASME and API specification are included in the scope.Forgings to this specification are limited to 10,000 lbs.

A 105 is an ASTM steel forging specification mainly used for carbon steel forged piping components. This type of carbon steel forging alloy involved is a low carbon, manganese and silicon containing steel similar to AISI 1330, but with lower manganese content

What is the Difference Between A105 and A105N Fittings

The main difference between them is their heat treatment. A105N undergoes normalization heat treatment, which increases its strength, toughness, and performance at low temperatures. A105 has no heat treatment requirement, and has a higher carbon content, which gives it its hardness
