Naylor Spiral Buttweld can be furnished in industrial standard lengths of 20'0"; line pipe standard lengths of 40'0", 50'0" and 60'0"; and structural lengths up to 93'0". All piping can be cut to any required length to tolerance of plus-or-minus 1/8".
Naylor Spiral Buttweld Pipe features two welds along the spiral seam. This creates a pipe structure in which the weld is as strong or stronger than the parent metal.
Because thickness tolerances of steel strip are governed by the standards established by the American Iron and Steel Institute, uniform wall thicknesses are assured. This minimizes irregularities which could cause uneven wear.
The Naylor manufacturing process creates a pipe that maintains an accurate diameter throughout its length. The uniformity of the pipe ends speeds connections, whether mechanically coupled or welded.
INSPECTION AND TESTING
Every length of Naylor pipe is inspected and where required is tested to the hydrostatic mill test pressure specified in the applicable ASTM specification.
Naylor Spiral Buttweld Pipe is manufactured in a wide range of wall thicknesses. The fact that this pipe is available in lighter weights than other pipe makes it possible to save money, not only on the initial cost but also in transportation, handling, and installation. It means that by sizing the diameter of the pipe to the exact requirements, with exact lengths and factory-sized ends, the greatest economies can be realized.
