How to Calculate Steel Pipe Weight per Foot/Meter by Size Length 1m 10m Diameter 89mm Drilling Rod Drill Pipe

Please note The steel pipe nominal weight is that the product of its length and its mass per unit length (Per foot or per meter) For example The description of API 5L seamless steel line pipe , Outer Diameter is 6 5/8 inch (168.3 mm), Pipe Wall Thickness is SCH 40 (7.11 mm or 0.280 inch), length 12 meters. Horizontal Directional Drilling for Large Diameter PipeOnce the bore head reaches the end of the path and breaks the surface, the final drill -path is complete. Now, a back reamer is attached to the boring rods and the back reamer is then drawn back through the bore path. As the back reamer advances it simultaneously increases the diameter of Horizontal Directional Drilling - HDD - E&M Supply GroupThese rigs are used on bores that start at around 1,500 ft in length , and go up to as long as 8,000 in length . HDD maxi rigs use the same drill pipe that is used by the oil and gas industry. The most common drill pipe sizes used by maxi rigs are 5, 5 1/2, and 6 5/8 OD x 31ft long drill pipe .
