Brief Introduction

for TF Type Self-anchored Joint Pipe

 

  

1. TF Type Self-anchored joint

 1.1  Principle

The principle of joint anchoring consist in transmitting the axial forces from one pipeline component to the following one, thus ensuring that the joint does not come apart.

Self-anchored joints allow the axial thrusts arising at particular points ( bends, tapers, tees, blank flanges) to be distributed over one or more ipes, thus avoiding installation of concrete anchor blocks.

 

1.2 Description

  

The Seal is provided by a T type socket

The axial force transmission is through a mechanical arrangement independent of that providing the seal , comprising:

- works applied weld bead on the pipe spigot

- a one-piece anchoring locking ring, with a curved external profile, whick abuts against the weld bead

- a special gland, which blocks the locking ring.

- iron bolts

2. Assembly – TF type self-anchored joint

Assembly of TF type self-anchored joint is achieved by pushing a spigot into a T type socket, then holding it in position with an anchoring system comprising a locking ring and bolted gland.

If a pipes is cut on site, the spigot has to be chamfered and anchor bead has to welded on.
