LNG installation uses extra large
connectors
When Vector International manufactured some of the largest ever pipeline clamp connectors, for an LNG installation, Arc Energy Resources was asked to apply a corrosion resistant alloy coating
Qatargas 3 and Qatargas 4 are two of the world's largest LNG developments: combined, they are expected to generate approximately 2.8 billion cubic feet per day of natural gas Among the equipment specified for two well head platforms that will deliver these enormous volumes of gas, are hundreds of Techlok Clamp Connectors from Vector International, which were specified for their combination of compact design, light weight and leak free operation in critical applications

Protecting new and refurbished oilfield valves
Weld overlay cladding specialist Arc Energy Resources has applied a coating of corrosion resistant alloy for A Finkl and Sons, to protect a brand new oilfield valve and refurbish an old one
South Wales based Vector International is renowned for its compact connection and sealing solutions for piping and vessel and pressure containment in the oil and gas industry.
Its Techlok clamp connectors offer a number of significant advantages, including a 75% weight saving compared to conventional flange connections.
Of the hundreds of Techlok connectors delivered on this project, a number needed the corrosion proof protection provided by the specially formulated Alloy 625, which is applied by weld overlay cladding.

Specialised weld overlay cladding by Arc Energy Resources was specified by Wellman Graham to provide corrosion protection on heat exchanger tube sheets destined for a new methanol plant in Trinidad
Vector International has for many years used Gloucestershire based Arc Energy Resources to carry out weld overlay cladding on Techlok connectors for projects of this type.
But as Gary Walford of Vector explains, it isn't the number of connectors that sets this project apart, it's the fact that these Techlok connectors were sized for 42 inches, which the company believes to be the largest clamp connectors of this type produced anywhere in the world.
Says Gary: "We have also supplied 26 inch and 12 inch connectors to Qatargas 3 and 4, but we have never manufactured anything as big as the 42 inch connector before, and we don't think anyone else has.
The sheer size of the connectors made this cladding operation special.
The fact that we had to apply our usual quality standards to such a large piece of equipment also meant that it was a very technically demanding project for us and for Arc Energy".
Also, due to the size and the tight tolerances specified it was decided to stress relieve the connectors after weld overlay cladding.
Even with items as large as these Arc Energy was able to carry out the post weld heat treatment in one of its own calibrated furnaces.
Summing up, Gary says he was confident that by working with Arc Energy, Vector would get the best workmanship and service, and even though it was a major project and deadlines were sometimes tight, the work was always delivered on time.
