Many people call Laterals “45° Wyes”. At OK Pipe, we refer to them as 45° Laterals and Wyes as “True Wyes”. Reducing laterals and laterals at angles other than 45 degrees are also available. OK Pipe has fabricated laterals in sizes 1 1/4″ up to 96″!
We fabricate our laterals and wyes, through 12”, from A106 Grade B pipe and our welds are qualified per ASME Sect IX. Larger laterals are made from API 5LB pipe or rolled and welded cylinders, unless specified by the customer prior to manufacturing. We can fabricate these in carbon steel and stainless, in any wall thickness. In addition to Laterals and True Wyes, we also fabricate Double Laterals as seen here:
