Pipe Fittings Manufacturing Standards and Types

Published on 14 August, 2024

At Online Fittings, we understand the importance of reliable components in your piping systems. While pipes take center stage, the unsung heroes are the fittings that ensure a smooth flow and strong connections. Let’s talk about forged pipe fittings, exploring the standards that govern their creation and the various types available. 

 

Built to Withstand Pressure: Forged Pipe Fitting Manufacturing Standards

 

Unlike cast fittings, forged fittings are crafted from solid metal blocks. Intense heat and pressure are applied, shaping the metal into the desired fitting form. This process results in exceptionally strong and resilient components, making them ideal for high-pressure applications. But how do we ensure their quality and consistency?

 

Several crucial standards oversee the manufacturing of forged pipe fittings. Here are the main ones: 

 

ASME B16.11: This American Society of Mechanical Engineers (ASME) standard dictates the dimensions, tolerances, pressure-temperature ratings, material requirements, and markings for forged fittings. By adhering to ASME B16.11, manufacturers guarantee fittings that seamlessly integrate with pipe conforming to ASME B36.10 and B36.19 standards.

MSS SP-75, SP-83, SP-95: These Manufacturer's Standardization Society (MSS) specifications supplement ASME B16.11, providing additional details on material properties, inspection procedures, and testing requirements for specific fitting types.

 

Choosing the Right Tool for the Job: Diverse Forged Pipe Fitting Types 

 

Forged fittings come in a wide array of shapes and sizes, each catering to unique piping needs. Here's a look at some of the most common types:

 

1. Elbows: These fittings change the direction of flow, typically at 90 or 45 degrees. They are available in threaded and socket-weld configurations.
Socket Weld: 45° Elbow, 90° Elbow, 180° Elbow.
Threaded: 45° Elbow, 90° Elbow, 180° Elbow.

2. Tees: T-shaped fittings with one inlet and two outlets, used for branching or merging pipelines. They come in equal (all three openings are the same size) or reducing (one outlet has a smaller diameter) variations.
Socket Weld: Equal Tee, Reducing Tee.
Threaded: Equal Tee, Reducing Tee, Lateral Tee.

3. Couplings: Simple straight fittings that connect two pipes of the same diameter.
Socket Weld: Half Coupling, Full Coupling.
Threaded: Full Coupling, Half Coupling.

6. Reducers: Designed to connect pipes with different diameters, allowing for smooth transitions in pipe size.

7. Unions: Three-piece fittings enabling easy disconnection of a pipe segment for maintenance or inspection.
Threaded: Union.

8. Caps and Plugs: Caps seal off the end of a pipe, while plugs screw into a threaded opening to block it.
Socket Weld: End Cap.
Threaded: End Cap, Plugs.

 

Material Matters: Selecting the Right Forged Fitting Material 

 

The material used in forged fittings plays a crucial role in their performance. Here are the two most common options:

 

Carbon Steel (ASTM A105): This cost-effective material is widely used for moderate-pressure applications. Its versatility makes it suitable for various industries.

Stainless Steel (ASTM A182): Offering superior corrosion resistance, stainless steel finds favour in environments with harsh chemicals or high temperatures.
