What does B16 9 mean?

The ASME/ANSI B16. 9 specification covers the dimensions and the tolerances of carbon and alloy butt weld fittings. The MSS-SP 43 specification integrates ASME B16. 9 to cover stainless steel and nickel alloy pipe fittings. In this article, we show the dimensions and weights of buttweld elbows, tees, and reducers.

What is the grade of forged fittings?

Each fitting has a class grading of 3000, 6000, or 9000, representing the maximum pressure that the stainless steel forged fitting can withstand. Pipes in schedule 80/XS require class 3000 fittings, pipes in schedule 160 require class 6000 fittings, and XXS pipes with thicker walls require class 9000 fittings.

What is the pressure rating of 3000 fittings?

The 3000 pound threaded fitting has a pressure rating of 3000 pound maximum pressure rating.

What is a socket weld?

A Socket Weld is a pipe attachment detail in which a pipe is inserted into a recessed area of a Valve, fitting or flange. In contrast to buttweld fittings, Socket Weld fittings are mainly used for small pipe diameters (Small Bore Piping); generally for piping whose nominal diameter is NPS 2 or smaller.

Stainless Steel Threaded Fittings ASME B16 11

What are the 5 basic types of welding joints?

There are five basic welding joint types commonly used in the industry, according to the AWS:
  • Butt joint.
  • Tee joint.
  • Corner joint.
  • Lap joint.
  • Edge joint.

What is SW in piping?

Socket Weld (SW) fittings are defined in the ASME B16. 11. As with socket weld, a pipe is inserted into a recessed area of the fitting. Both the pipe and the fitting are square cut, with no need for beveled end or preparation other than cleaning the outside, which allows easy welding and installation.

What is class 3000 steel?

The class 3000 fittings consist of multiple components made of stainless steel, like 90-degree elbow, straight and reducing tee, cross, steel pipe coupling, cap, union, and lateral. The Class 3000 Stainless Steel Fittings are used only in conjunction with the ANSI pipes, which are available in a similar size range.

What pressure is a 300 flange rated for?

the class 300 flange (bigger and stronger, but with the same bore size) withstands 570 psi at the same temperature of 600 degrees F°

What is class 150 pressure rating?

As temperature increases, the pressure rating of the flange decreases. For example, a Class 150 flange is rated to approximately 270 PSIG at ambient conditions, 180 PSIG at approximately 400°F, 150 PSIG at approximately 600°F, and 75 PSIG at approximately 800°F.

What does ASME B16 11 mean?

ASME B16. 11 is the standard for the forged steel fittings, including socket weld and threaded type. Material including carbon steel, alloy steel and stainless steel. Also described as Class 2000, 3000, 6000 threaded end fittings and Class 3000, 6000, and 9000 for socket weld end fittings.

What is A234 WPB?

What is ASTM A234 WPB. ASTM A234 is Standard Specification for steel pipe fittings includes carbon and alloy steel material for moderate and high temperature services. It covers steel fittings of seamless and welded types. Steel Pipe fittings are applied in pressure pipelines and in pressure vessel fabrications.

What is difference between wrought and forged?

Wrought is any hot or cold working of metal, and is therefore a description under which you would find forging, rolling, heading, upsetting, drawing, etc. Forging is the open (including hammer and anvil or closed die forming of metal heated to forging temperatures.

What B16 25?

ANSI/ASME B16. 25 is the standard covers the preparation of butt welding ends of piping components to be joined into a piping system by welding. The standard includes the butt welding ends information of General scope, Welding Bevel designs, Preparation of inside diameter of welding ends and the tolerances involved.

What is ANSI B16 34?

ANSI/ASME B16.34 valves-flanged, threaded and welding ends covers process. valves with flanges, butt weld, socket weld and threaded ends. It defined pressure- temperature ratings, materials, design requirements and wall thickness for process. valves.

Is ASME and ANSI same?

ANSI establishes and accredits performance and quality standards for products and services in a wide variety of sectors, while ASME is primarily focused on boilers and pressure vessels.

Are 300 and 600 flanges the same?

The difference between these three flanges is the pressure class! This is a class 150, this is a class 300, and this is a class 600. The differences are in the dimensions except for the bore!

What means Class 150?

The American National Standards Institute (ANSI) Class 150 is a system of dimensional standards for weld neck, threaded, slip-on, lap joint, socket weld and blind flanges. Dimensions for facing, bolts and studs are also included in ANSI Class 150.

What is the pressure rating of a 600 flange?

2 at a temperature of 650°F (343°C), a Class 600 flange is found to have a rating of 890 psig (6136 kPa gage) at 650°F (343°C). Therefore, a Class 600 ASTM A182 flange is suitable for the stated conditions.

What is ASTM A105?

ASTM A105 (also known as ASME SA 105) covers seamless forged carbon steel piping components for use in pressure systems at ambient and high-temperature service.

What is a Threadolet fitting?

Threadolet is a type of self-reinforced branch fitting developed by a Company called Bonney Forge. It is used whenever threaded branch connections are required from the pipe header. Mostly, it is used for small size piping with a low-pressure application. Threadolets are available in full size or reducing size.

What is a half coupling?

Half Coupling is used for small bore branching from a vessel or large bore pipe. It can be threaded or socket type. It has a socket or thread end on only one side. A socket weld half coupling can be directly welded to large bore pipe, to make a branch connection.

What is FW in piping?

FW = field weld. FFW = field-fit weld. A field-fit weld indicates that the designer has foreseen that the piping may need adjustment in the field so has added an extra length of pipe at a buttweld fitting or flange.

What is BW and SW for welding?

The SW seams are fillet welds. The BW seams are butt welds,and there is a high requirement for welding. 4.

What does SW stand for in welding?

The final process within the arc welding group of processes is known as stud arc welding (SW). This process is defined as “an arc welding process which produces coalescence of metals by heating them with an arc between a metal stud or similar part and the work piece”.
