How is forged pipe made?

In a Forging pipe manufacturing process, a heated billet is placed in forging die that has a diameter slightly larger than the finished pipe. A hydraulic press of forging hammer with matching inside diameter is used to create cylindrical forging. Forged pipes are normally used for the steam header.

What are forged fittings?

Forged fittings are made of A105 (carbon steel), stainless steel or nickel alloy. These fittings are thicker, heavier and are intended for heavy industrial use. Forged Iron Pipe Fittings are available in 2000#, 3000#, 6000# and 9000# pressure class. These fittings are more common in 3000# and 6000# (90\% of the time).

How are wrought pipe fittings made?

That is to say wrought pipe fittings are fittings that forged by impact force. By forging the pipe parts, compacting and welding the original segregation, looseness, porosity and slag inclusion in the ingot, the structure becomes more compact and the plasticity and mechanical properties of the metal are improved.

How are socket weld fittings made?

These fittings are manufactured by forging and machining solid steel and are available in a multitude of shapes like elbows, tees, reducers, unions, couplings. The ASME B16. 11 specification covers socket and threaded fittings for oil and gas application. For larger pipe sizes, ASME B16.

Are forged fittings seamless?

The regular fittings are either hammered or cast. Wrought fittings are made utilizing only seamless pipes. The machine creates broad diameter welded fittings. Forged pipe fittings (Socket Weld and Threaded) are created in compliance with the standards of ASME (American Society of Mechanical Engineers) B16.

How are fittings manufactured?

Fittings are manufactured from Seamless Pipe and from Welded Pipe with filler material (ERW & EFW pipes cannot be used to manufactured fittings). To manufactured wrought fitting various methods are used, these are the different types of Hot and cold forming processes.

What is the difference between Sockolet and Weldolet?

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.

What is the difference between socket weld and fillet weld?

In pipe systems fillet welded joints are generally used for joining pipe to socket joints in sizes NPS 2 and smaller, and in systems where Slip On flanges will be used. The disadvantage of a Socket Weld system is right the expansion gap and the space between the OD of the pipe and the ID of the fitting.

What is socket welding?

Socket welding(SW) is the welding method of pipeline insertion.It is welded two different sized pieces of pipe,the smaller one is inserted into the large one. The weld is completely in the periphery of the large pipe and it is fillet weld.

How are forged elbows made?

Elbows of steel pipe joints are used in the industrial plants and are mainly manufactured by the hot mandrel bending from raw material of straight steel pipe. Elbows are generally manufactured at elevated temperature by means of pushing, expanding and bending of pipes simultaneously, using the inner tool of mandrel.
