Carbon Steel threaded pipe fittings are generally used for small size pipes and piping systems (generally below 4 inches in diameter for Class 3000, and below 2 inches for fittings in class 6000 and 9000). Carbon Steel threaded pipe fittings are manufactured by forging, followed by heat treatment and machining solid steel as per ASME B16.11 and other dimensional standards. For bigger size piping systems buttweld pipe fittings produced as per ASME B16.9 are used.

The B16.11 standard covers pressure-temperature ratings, dimensions, tolerances, marking, and material requirements for forged carbon and alloy steel. Acceptable material forms are forgings, bars, seamless pipe, and seamless tubes which conform to the fittings chemical requirements, melting practices, and mechanical property requirements of ASTM A105, A182, or A350. ASME B16.11. Forged fittings are available with two types of end connections, which are called “socket weld” and “threaded”. Metallica is engaged in the production and trade of all kinds of carbon steel threaded pipe fitting finished and unfinished products. 90 degree carbon steel threaded pipe fitting is our main production and sell as well.

Types of Carbon Steel Threaded Fittings

Our Main Products of Threaded Pipe Fittings

Threaded fittings are normally made of cast gray or malleable iron, cast brass or bronze, or forged alloy and carbon steel. They are available in three pressure ratings: Class 2000, 3000 and 6000. At the smallest sizes, the amount of wall lost during threading actually equals approximately 55% of the original pipe wall.

Socket weld and Threaded Pipe Fittings are forged product and classified based on its pressure-temperature rating. Socket weld & Threaded end fittings are available from NPS 1/8” to 4”. These fittings are available in four pressure-temperature rating class.

• 2000 class fittings are available in only in threaded type.
• 3000 & 6000 class fittings are available in both Threaded and Socket Weld types.
• 9000 class fittings are available in only socket weld type.

Socket and threaded fittings are used for small bore and low-pressure piping.

Manufacturing Process for Carbon Steel Threaded Pipe Fittings

• Forged fittings are the fittings made by forged steel. The process of manufacturing forged steel fittings include: cutting and heating billets, put pressure on heated billets under dies into desired shape, trimming and shot blasting. Then machine forged blank fittings for net shape and dimensions. According to the applications of forged steel fittings, they are available in threaded and socket weld end connections.
• The main raw material for producing forged pipe fittings is round bar stock or billets.
• Most of the forged steel fittings are not large, so closed die forging is normally adapted to produce forged steel fittings. Compared to the open die forging, the close die forging can achieve more complex geometries, very much close to the dimensions of the finished component.
• Close die forging can produce forged fittings in all materials such as carbon steel, duplex, stainless steel or nickel alloys.

Types of Carbon Steel Socket Welded & Threaded Forged Steel Pipe Fittings

1. Carbon Steel Threaded Elbows (90 Degree Elbows and 45 Degree Elbows) – A pipe elbow is a forged steel fitting installed between two lengths of pipe or tube allowing a change of direction, usually in the 90° or 45° direction. Similar to a reducing tee, reducing elbows also exist to simultaneously change flow direction and reduce flow diameter. Street Elbows have one female end to accept pipe and another male end thread that is the same size as the pipe and can avoid the use of a pipe nipple during installation.
2. Carbon Steel Threaded Tees (Equal Tee and Reducing Tees)– Tees are a type of forged steel fitting used to combine or divide process flow, and Reducing Tees additionally allow for pipe size change. The run outlets of the tee are the two in-line outlets, and the branch is the third outlet. The branch outlet is the reducing outlet in a reducing tee.
3. Carbon Steel Threaded Couplings (Straight and Reducing Couplings, Full and Half Couplings) – Couplings are a forged steel fitting used to connect two lengths of pipe, and Half-coupling is screwed onto the pipe, while the other end is made to be tightly inserted, or welded, onto the other end to pipe or vessel. Standard Couplings have female threads or open sockets at both ends, whereas reducing couplings connect smaller pipes to larger ones.
4. Carbon Steel Threaded Unions– Unions are a forged steel fitting similar to a coupling but allow a convenient disconnection and connection; it has 3 parts: a nut, a female end, and a male end. They allow two lengths of pipe to be assembled and detached without causing any deformation to the pipes.
5. Carbon Steel Threaded Bushings (Hex Head Bushings and Flush Bushings) – Reducing inserts and Bushings are forged steel fittings that allow for a change in pipe size. Pictured here is the hex head bushing, which is most commonly used.
6. Carbon Steel Threaded Caps (Pipe Caps and End Caps) – Caps are forged steel fittings used to terminate the flow, inserting over the end of the pipe.
7. Carbon Steel Threaded Plug (Square Head Plugs, Hex Head Plugs and Round Head Plugs) – Similar to a cap, plugs are forged steel fittings that are inserted into the end of the pipe, and they come with different head types, including: hex, square, and round.
8. Carbon Steel Threaded Cross – Crosses are a 4-way forged steel fitting, with 1 inlet and 3 outlets or vice versa. These are sometimes referred to as 4-way tees.
9. Carbon Steel Threaded Outlets (Weldolets, Sockolets, Threadolets, Elbolets, Latrolets and Nipolets)
10. Carbon Steel Threaded Nipples (Hexagonal Nipples and Swaged Nipples)

Advantages of Carbon Steel Threaded Pipe Fittings

• Material performance superiority
• Advantages of environmental protection
• The superiority of connection technology
• The superiority of appearance
• Cost-effective superiority
• Quick connection and safe installations
• Remarkable corrosion resistance
• Superior crush resistance
• Installation productivity is moderately high, and specialized installation skill requirements are not extensive.
• Leakage integrity is good for low-pressure, low-temperature installations where vibration is not encountered.

Disadvantages of Carbon Steel Pipe Fittings

• In hazardous piping systems threaded connections should be avoided, if possible. Their vulnerability to fatigue damage is significant, especially where exposed threads are subject to corrosion.
• Rapid temperature changes may lead to leaks due to differential thermal expansion between the pipe and fittings.
• Vibration can result in fatigue failures of screwed pipe joints due to the high stress intensification effects caused by the sharp notches at the base of the threads.

Difference Between Socket Weld Pipe Fittings and Threaded Pipe Fittings

1. Socket weld fittings are used for applications where strong and long-lasting connections are required.  Socket weld fittings are very reliable but are time-consuming to install in a piping system (due to the heavy workload caused by welding operations on small parts). Threaded fittings are used for less-critical piping systems, such as water distribution, fire protection, and cooling, or for low-pressure installations not subject to vibration, elongation and bending forces. Threaded pipe fittings are not suited for fluids with constantly changing temperatures, as sudden changes may crack the connection.
2. Socket weld fittings are connected to pipes by fillet welds, whereas threaded fittings are screwed onto the pipe or vice-versa.

Difference Between Malleable Iron Pipe Fittings and Threaded Pipe Fittings

A malleable iron fitting is used for light industrial application, plumbing application. These threaded fittings have a high pressure rating, they are made out of a forged steel. One big difference is that malleable iron fitting is not very good with welding whereas, threaded fitting, you can weld. Again, this is a threaded fitting, but depending on your application, if there is a requirement to weld it, then you would be better off using a forged carbon steel. Also, malleable iron fitting come in 150 pound, 300 pound rating which you can make a comparison, much lower, whereas a threaded fitting come in a 3000 and 6000 pound pressure rating.
