Composition of Type C2F Double-Flange Loose Sleeve Force-Transfer Joint

Sep 17, 2025

Type C2F Double-Flange Loose Sleeve Force-Transfer Joint is composed of components such as a flange-type loose sleeve expansion joint, short pipe flange, and force-transfer screw. It can reduce the pressure thrust (blind flange force) of the connected parts and compensate for pipeline installation errors, but it cannot absorb axial displacement. This joint is mainly used for the loose sleeve connection of accessories such as pumps and valves.

 

I. Application Scope

Type C2F Double-Flange Loose Sleeve Force-Transfer Joint is suitable for conveying media including seawater, freshwater, cold and hot water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, finished oil products, air, gas, steam (with a temperature not exceeding 250°C), and granular/powdered substances.

 

II. Function Introduction

The Double-Flange Loose Sleeve Force-Transfer Joint, designated as Model VSSJAF (per the 1999 Standard) or Type C2F (per the 2007 Standard), consists of a flange-type loose sleeve expansion joint, short pipe flange, force-transfer screw, and other components. It can transmit the pressure thrust (blind flange force) of the connected components and compensate for pipeline installation errors, but it cannot absorb axial displacement. It is mainly used for the loose sleeve connection of accessories like pumps and valves.

 

Advantages

  • Simple and convenient installation
  • Facilitates valve installation
  • Capable of withstanding the axial tension of pipelines
