"PFS have recently undertaken the fabrication and installation of a Recovery Boiler air system upgrade at Carter Holt Harvey's Kinleith Pulp and Paper Mill in New Zealand for Andritz Oy of Finland. This work included the installation of new boiler waterwall panels, ducting and piping.

There were nine new waterwall panels installed, each consisting of six tubes 63.5 mm 00, and so in total there were 108 site welds required. Recovery boiler tube welds are 100% radio graphed and inspected to a very exacting specification. PFS achieved the unusually high standard of zero failures, which is a result they can be proud of. This is equal to world best practice. PFS manufactured and installed the ductwork including the three sets of aerofoil flow meters. This was a challenging job with tight tolerances and was well done.

We found PFS reliable, well organised, honest and easy to do business with. Their safety systems were very good. They achieved the critical time schedule required and with consistently good quality. We would be pleased to work with PFS again."

"I like to take this opportunity to say well done to all your engineering staff that has worked on any of the rotational moulding tooling that we have sent in for modifications or repairs, the general consensus from staff members here is that they are very impressed with the finish and workmen ship that has been done. I have found the finish to be of a high standard that is comparable to an expert mould making company and we will continue to send tooling in to be repaired / modified knowing it will be good hands.

Also I would like to say well done to all the on-site service staff that have worked on tooling at our factory; this has also been complete in a very tidy manner and to a high standard. I have always found them very professional to work with."

"109 welds completed 100% pass rate - outstanding!

Congratulations to the PFS team for achieving their goal of 100% butt weld pass rate. This was a tough goal given our high acceptance standards and was not achieved by accident - but was a result of good planning, training, weld preparation and a team of skilled welders."

"A short email to say thanks to you and the team for the support and repair work on the incinerator last week, line has been started and heat applied. I really appreciated the professionalism of your team and their attitude to safety and engineering, please pass on my thanks"

"I would like to write to you both to thank you for the prompt response and good capable work that was carried out at Fonterra - Canpac by your tradesmen in the repair of our Oven Incinerator. We were particularly impressed by the quiet and efficient manner that the tradesmen just got down to work and the professional manner in which the work site was organised. It was quite clear that ‘safety’ was paramount and that the men were well equipped with the resources to isolate the work space from the adjacent Production environment."
