Detailed Introduction

Threadolet for Reliable Threaded Branch Connections

A Threadolet is a type of forged branch outlet fitting designed to connect a smaller branch pipe to a main pipeline through a threaded connection. It provides a reinforced branch connection without requiring welding, making it suitable for applications where welding is difficult or where a removable connection is preferred.

Unlike traditional threaded couplings, Threadolets are specially designed with a contoured base that matches the curvature of the run pipe, providing better reinforcement and stress distribution.

DTC manufactures and supplies forged Threadolet fittings according to ASME B16.11 and MSS SP-97 standards. Available in carbon steel, stainless steel, and alloy steel, our Threadolets are widely used in oil & gas, chemical processing, power generation, and industrial piping systems.


Key Features of Threadolet

Reinforced Branch Connection

The forged design provides additional strength around the branch opening, reducing stress concentration.

Threaded Installation

The threaded outlet allows fast installation without welding, making it suitable for maintenance-friendly piping systems.

Compact Design

Threadolets require less installation space compared with conventional branch fittings.

High Pressure Capability

Forged construction provides excellent mechanical strength for demanding applications.

Wide Material Options

Available in various materials to meet different temperature, pressure, and corrosion requirements.
