Gemini is pleased to announce a strategic development programme to meet the growing demand for thermal spray corrosion protection solutions to the oil and gas industry. The programme began with the re-introduction of this capability into Gemini's Stonehaven facility in April 2005. Phase two is a new, purpose built, fully automated, state of the art computerised thermal spray hall in Gemini Montrose's site. This facility is the first of its kind in the UK and Europe, and began operation in January 2006.

Sprayed metal coatings have been used for many years, and the process is an excellent means of protecting steel from corrosion to almost any degree. Equipment can be handled almost immediately after application, has superior abrasion resistance and can be further enhanced by the application of sealers and organic materials, such as paint, as and where required.

The equipment can be used to spray pipes from 4 inches to 48 inches (102mm to 1.22m) in diameter and from 6.6 feet to 50 feet (2m to 15.24m) in length. A control box is provided to allow the storing of up to 20 preset programmes, with RPM and Carriage Traverse Rates, to ensure an even coating thickness.

By automating the process, an even coating can be guaranteed along the complete length of the pipe, which will realise potential material savings of up to 20%. Spray times will also be reduced, allowing a quicker turnaround time and increasing the capacity of the plant. In the Arcspray process, the raw material, a pair of metal wires, is melted by an electric arc. The molten material is atomised by a cone of compressed air and propelled towards the work piece. This spray solidifies when it hits the surface of the work piece to form a dense coating, which protects against corrosion or reclaims/repairs components.

Increased awareness within the industry of the advantages of thermal spray protection and an expanding customer base of confirmed orders underpins this investment project. Says Ian Guthrie, Managing Director of Gemini, "We are at the forefront of coating technology, and are continually investing in state of the art equipment and expanding our expertise to remain at the forefront of corrosion protection within the oil and gas industry".
