Itis made from steel strip on automatic equipment designed byNaylor that forms, sizes and completes the manufacture; first,by a sound initial penetrating weld, then followed by a secondweld along the outside spiral seam.
But the technology to produce spiral-weld pipe suitable for hig h-pressure uses was developed only in the 1960s [3]. A method for manufacturing h elically formed and welded pipe was patented in 194 0.
American SpiralWeld Pipe Company, LLC (ASWP), a subsidiary of American Cast Iron Pipe Company, is expanding its spiral-weld operations to Paris, Texas. ASWP estimates making a substantial initial capital investment in pipe making technology in the range of $70 million to $90 million. The company plans to initially staff the plant with ...
2.2 Investigated pipeline sections. Spiral welded (submerged arc welding) steel pipeline sections with girth welds were examined. The main parts, which are the middle parts, in other words the investigational parts of the girth welded pipeline sections, were cut from operating pipelines after long-term operation.
This specification covers spiral-weld line pipe in grades A, B, X42, X46, X52, X56, X60, X65, X70, and grades intermediate thereto. The chemical composition and certain physical properties of intermediate grades are subject to agreement between the purchaser and manufacturer. The agreed-upon requirements must be consistent with the ...
Abstract. Submerged arc welding (SAW) is generally the preferred method for joining the seam edges of large diameter spiral pipes. The quality control of the welded pipes usually consists of a hydrostatic test in which water is pumped into the pipe. High pressure hydrostatic tests can moderate tensile residual stress caused by the welding …
We stock a huge selection and variety of sizes, lengths, diameters, and different types of spiral pipe including the most common sizes ranging from 18" to 126" in diameter and from .25" to 1" in wall thickness. We can …
Difference Between ERW Pipe and Spiral Weld. However, spiral weld pipes are more expensive to produce than ERW pipes. They also tend to have more variability in the wall thickness, which can result in inconsistencies in the quality of the pipes. This, in turn, affects their suitability for use in specific projects.
