Product Summary

pdf

Seamless coupling is a coupling which is seamless. A coupling is a very short length of pipe or tube, with a socket at one or both ends that allows two pipes or tubes to be jointed, welded (steel), brazed or soldered (copper, brass etc.) together. Alternatively it is a short length of pipe with two female NPT (National pipe threads) (in North American terms, a coupler is a double female while a nipple is double male) or two male or female British standard pipe threads. If the two ends are different, for example one BSP threaded and one NP threaded, then it is usually referred to as an adapter. Another variation is one plain socket and one threaded socket. Yet another variation would be 3/4" NPT to 1/2" NPT. When the two ends are of a different size it is called a reducing coupling or reducer. Elbows are basically used to change the direction of the fluid flow. Two kind of elbows are used: 90 deg. elbow and 45 deg. elbow; 45 deg. elbows are also used in rolling of pipe.

Seamless (SMLS) coupling is formed by drawing a solid billet over a piercing rod to create the hollow shell. Seamless coupling withstands pressure better than other types, and is often more easily available than welded pipe. Welded (also Electric Resistance Welded, and Electric Fusion Welded pipe is formed by rolling plate and welding the seam. The weld flash can be removed from the outside or inside surfaces using a scarfing blade. The weld zone can also be heat treated to make the seam less visible. Welded coupling often has tighter dimensional tolerances than seamless, and can be cheaper if manufactured in the same quantities.
