What are Threaded Pipe Fittings? Similarity Between Socket Weld Pipe Fittings and 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.

What are the Applications of Threaded Pipe Fittings?

Threaded piping is commonly used in low-cost, noncritical applications such as domestic water, fire protection, and industrial cooling water systems.

What are the Advantages of Threaded 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.

What are the Disadvantages of Threaded 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 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 Fittings and Threaded Forged 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.

What are the Different Tools Used to Measure Threaded Pipe Fittings?

  1. Caliper – A caliper is a useful tool that measures the outside diameter of a male thread and inside diameter of a female thread. Using a caliper will give you the most accurate and precise measurements, but a straight steel ruler is a good alternative.
  2. Pitch Gauge – A pitch gauge measures the threads per inch. For metric threads, this tool measures the distance between the threads.

Effects of Alloying Elements on Steel

•Manganese – strength and hardness; decreases ductility and weldability; effects hardenability of steel.
•Phosphorus – increases strength and hardness and decreases ductility and notch impact toughness of steel.
•Sulfur decreases ductility and notch impact toughness Weldability decreases. Found in the form of sulfide inclusions.
•Silicon – one of the principal deoxidizers used in steel making. In low-carbon steels, silicon is generally detrimental to surface quality.
•Copper – detrimental to hot-working steels; beneficial to corrosion resistance (Cu>0.20%).
•Nickel – ferrite strengthener; increases the hardenability and impact strength of steels.
•Molybdenum –  increases the hardenability; enhances the creep resistance of low-alloy steels.

How are Steel Pipes Certified?

Certification of Steel Pipes

Manufacturers issue a Material Test Report or Mill Test Report to validate that the product meets the chemical analysis and mechanical properties specification. The MTR will contain all relevant data to the product and will accompany the product through its lifecycle.

The following are typical parameters that may be recorded on an MTR:

  • Chemical composition including carbon content, alloys, and sulfur
  • Material size, weight, identification, and grade
  • Material heat number, which ties back to the processing batch
  • Mechanical properties like tensile strength, yield strength, and elongation

At Metallica, we will Provide you with Original MTR’s for all Alloy Steel Pipe Products! We will Send Our Test Certificates, along with Quotation
