Forged Carbon Steel Pipe Fittings – Complete Guide

Introduction

Forged carbon steel pipe fittings are essential components in industrial piping systems, used to connect, control, and change the direction of fluid flow. Forged from high-strength carbon steel, they are designed to perform in demanding environments where high pressure, temperature, and mechanical stress are constant.

Fortis Forge specializes in manufacturing high-quality forged carbon steel pipe fittings, built to international standards such as ASME B16.11, MSS-SP-83, MSS-SP-95, and BS3799, ensuring durability, safety, and performance.

1. What Are Forged Carbon Steel Pipe Fittings?

Forged pipe fittings are made by shaping carbon steel billets under intense heat and pressure. This process aligns the grain structure of the metal, resulting in greater mechanical strength and fatigue resistance compared to cast fittings.

Why Forging?

• Improved tensile and yield strength

• Fewer defects and porosity issues

• Enhanced pressure handling capacity

• Consistent dimensional accuracy

2. Types of Forged Carbon Steel Pipe Fittings

2.1 Elbows

• 45° and 90° Elbows: Change flow direction

• Short & Long Radius: For compact or smoother flow applications

2.2 Tees

• Equal Tees: Branch of the same diameter as the main pipe

• Reducing Tees: Branch diameter smaller than the main pipe

2.3 Couplings

• Full Couplings: Connect two pipes of the same diameter

• Half Couplings: Connect a smaller pipe or fitting to a larger one

2.4 Unions

• Allow quick disconnection for maintenance or inspection

2.5 Caps

• Close the end of a pipe securely

2.6 Cross Fittings

• Allow four-way connection in a piping network

2.7 Nipples

• Small lengths of pipe for connecting fittings or valves

3. Classes & Pressure Ratings

Forged carbon steel pipe fittings are available in:

• Class 2000 – For low to medium pressure

• Class 3000 – For higher pressure industrial use

• Class 6000 – For extreme pressure and critical service applications

4. Standards & Specifications

Fortis Forge manufactures forged fittings as per:

• ASME B16.11 – Forged steel fittings for socket weld and threaded connections

• MSS-SP-79 / SP-83 / SP-95 – Various fitting types and dimensions

• ASTM A105 – Carbon steel forgings for piping

• ASTM A350 LF2 – Low-temperature service
