🔷 Forged Threaded Coupling (Full & Half)

ASME B16.11 Screwed Coupling Manufacturer – VikTech Fittings

🔹 Product Overview

VikTech Fittings is a trusted manufacturer and exporter of high-quality Forged Threaded Couplings (Full & Half) manufactured in accordance with ASME ASME B16.11 standards.

Threaded couplings are straight pipe fittings used to connect two pipes in a straight line. These fittings are internally threaded and are widely used in small bore high-pressure piping systems.

Available Pressure Classes:
✔ 2000#
✔ 3000#
✔ 6000#

Size Range: 1/8” to 4”

🔷 What is a Forged Threaded Coupling?

A Forged Threaded Coupling is a cylindrical fitting with internal threads on both ends, designed to join two threaded pipes together.

It provides:

✔ Straight-line pipe extension
✔ Secure threaded connection
✔ Easy installation without welding
✔ Reliable sealing performance

Forged construction ensures high mechanical strength and excellent pressure resistance.

🔷 Types of Forged Threaded Coupling

1️⃣ Full Threaded Coupling

A Full Coupling has threads throughout its entire internal length.

🔹 Features:

• Full internal threading

• Strong straight connection

• Suitable for permanent installations

• High-pressure resistance

🔹 Applications:

• Oil & gas pipelines

• Hydraulic systems

• Steam and condensate lines

• Chemical processing plants

2️⃣ Half Threaded Coupling

A Half Coupling is shorter in length and typically used for branch connections or tank outlets.

🔹 Features:

• Compact size

• Ideal for welding to pipes or vessels

• Used for branch connections

• Cost-effective solution

🔹 Applications:

• Vessel connections

• Instrumentation lines

• Pressure tanks

• Process equipment
