Spiral welding can be used in the remanufacturing process to repair and improve products. Improvements can be made to the component through this process by using a selection of advanced overlay materials; this is based on two broad criteria: [1] A match of the parent material with a filler wire of the same or closest available selection material.
Metal bellows are created by rolling annular corrugations into a smooth extruded or welded pipe. In 1946, Dreyer developed a multi-walled joint that was designed to accommodate axial movements as well: the axial expansion joint.
The most common process pipe joint is the butt weld. The ends of pipe to be welded must have a certain weld preparation called an End Weld Prep (EWP) which is typically at an angle of 37.5 degrees to accommodate the filler weld metal. The most common pipe thread in North America is the National Pipe Thread (NPT) or the Dryseal (NPTF
Partially-welded steel pipe joint. The welding of metals differs from soldering and brazing in that the joint is made without adding a lower-melting-point material (e.g. solder); instead, the pipe or tubing material is partially melted, and the fitting and piping are directly fused. This generally requires piping and fitting to be the same (or ...
Crater cracks occur in the crater when the welding arc is terminated prematurely. Crater cracks are typically shallow, hot cracks, usually forming single or star cracks. These cracks usually start at a crater pipe and extend longitudinally in the crater. However, they may propagate into longitudinal weld cracks in the rest of the weld.
NEWARK, Del, Nov. 11, 2024 (GLOBE NEWSWIRE) -- The global stainless steel welded pipe market, valued at approximately USD 2.8 billion in 2022, is projected to reach USD 8.9 billion by 2033, growing at a compound annual growth rate (CAGR) of 4.7% from 2023 to 2033.
