The advantages and disadvantages of ASME/ANSI B16.11 Threaded fittings

What are ASME/ANSI B16.11 Threaded fittings?

ASME/ANSI B16.11 threaded fittings refer to pipe fittings with threads. In industry, due to the improvement of professionalism and strict requirements on pressure resistance, it is usually made of metal threaded pipe joints, such as stainless steel, carbon steel and alloy steel.

Threaded fittings can be subdivided into more than a dozen types, covering a variety of forms such as straight connection and bending connection. There are threaded elbow, threaded tee, threaded coupling, threaded cap, threaded live joint, threaded nipple, reducing nipple, threaded plug, threadolet.

What pressure rating are threaded fittings?

Threaded fittings are most commonly used in a 3000 pound and a 6000 pound pressure rating. They are also available in 2000 pound.

The advantages and disadvantages of ASME/ANSI B16.11 Threaded fittings

Advantages

There are many kinds of threaded pipe fittings, which play an important role in pipeline connection and have advantages compared with other joints in all aspects. Best of all, threaded fittings are easy to use and easy to operate.

1. There is no need to use electricity, gas, fire and other AIDS when connecting pipes.
2. No special construction requirements, greatly improve the efficiency of the work.
3. The use of threaded pipe joint will not occur oil leakage and other conditions, high safety performance.
4. The size of the threaded pipe joint is many, in the case of small space also can ensure smooth operation.
5. The use of threaded pipe joint is simple, the general workers can complete the work smoothly. And it will not be affected by additional, to ensure the stability of the performance.

Disadvantages

1. Rapid temperature changes may lead to leaks due to differential thermal expansion between the pipe and fittings.
2. 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.
3. 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.
