Autoswage®

Based on our patented ball and taper technology, First Subsea has developed a range of high pressure pipe and tube fittings to complement the growing range of mechanical handling tools and connectors that are used throughout the world. Autoswage® is a simple, fast and more efficient way of connecting pipe without tools, with a high pressure capability, with is unique point - push - connect method of installation.

It comprises of load carrying mandrels within the Autoswage® connector, featuring ball and taper gripping technology. The connectors are a female/female type or female/welded type and they are designed to fit over the outside of the existing pipes/fittings of any size.

The compact Autoswage® connector provides:

Simple, fast and effective way of connecting pipe
Quick connect for a variety of liquids and gases applications and pressures
Simple point - push - connect all without tools
Stab on connection - no risk of applying too much or too little torque

Available in a range of different materials including:

Carbon steel
Stainless steel
Duplex
Super duplex
Inconel

Seals

The seals within the Autoswage® housing are impervious to oils, detergents, acids, alkalis, solvents and most gasses, which makes the application range of the connector considerable. As part of the testing regime, the seals and connector are tested under pressure at our facilities in Lancaster to ensure that a uniform seal is made around the pipe or umbilical.

Typical subsea applications include:

	Pipe Repair	Umbilical Intervention Connector
Information	Autoswage to bypass leaking valve and pipe on subsea manifold with limited access at approximate depth 400m	Umbilical Intervention Connectors (UIC) needed in response to leakage from two pipe members
Autoswage® Tool	Autoswage Inconel tools with Silicon Nitride balls	Double ended Autoswage design to suit 1” jumper tube
Sealing	Z70B (HNBR) seals with PEEK backup rings	PTFE and Nitrile Seals
Operating Pressure	3,750 PSI (258 Bar)	10,000 PSI (690 Bar)
Test pressure	4,688 PSI (323 Bar)	15,000 PSI (1,034 Bar)
