Designed for Flexibiity
For pipeline design and installation engineers,the Viking Johnsonl arge diameter couplings are extremely versatile. Each coupling sleeve is internally barelled, allowing greater angular deflection. Ideal when accomodating misaligned pipes
Large diameter couplings and flange adaptors are available in a wide range of sizes to suit virtually any customer requirement. Products can be supplied to suit all standard and non standard pipe diameters from DN350 to DN4000. Stepped couplings join pipes of different external diameters and flange adaptors can be supplied with flanges drilled toany national or international standard, or to customers’ ownspecification with a pressure up to PN100.
All products are designed and manufactured under quality management systems certified to ISO 9001 and conform to the American Water Works Association’s specification AWWA/ANSI C219 for bolted couplings.
