New large MaxiFit solves OD mismatch
problem
Viking Johnson extends the MaxiFit couplings range by adding a DN700 size - and helped Balfour Beatty in the cleaning and spray-lining of a 30Km stretch of the United Utilities Hodder trunk main
"The main, which is cast iron and dates from the 1920s, is classified as 27" but in practice there is considerable variation in OD, so we were having difficulty connecting make-up pieces at cut-out points," explained project manager John Harrison: "When we consulted Viking Johnson, they identified the 17mm tolerance of MaxiFit as the answer to our problem - and they were able to get the new DN700 size into production in time to meet our spray-lining schedule" MaxiFit is suitable for use with steel, ductile iron, PVCu, cast iron and asbestos cement - in fact all conventional pipe materials except PE - and guaranteed for a working pressure of 16 bar

In response to customer demand, Viking Johnson has added a DN225 / 9inch size to its range of EasiClamp units for repairing leaks on damaged pipes
The range includes standard, long-sleeve and stepped couplings, flange adaptors, and variants to suit customers' needs such as stainless steel bolts and Nitrile gaskets.
When it is bolted up, the exclusive MaxiFit 'slide easy' gasket provides maximum sealing pressure, even on the scored, pitted and corroded surfaces often encountered during repairs to older pipes.
All Viking Johnson products are designed and manufactured under quality management systems to BS EN ISO 9001 and have been tested in-house to the most exacting performance requirements of the UK Water Regulations Advisory Scheme (WRAS).
They also conform to the American Water Works Association specification AWWA/ANSI C.219 for bolted couplings.
