ASTM B366 INCONEL625 CAP UNS NO6625 DIN 2.4856 BUTT WELD FITTING
Overview
Inconel 625 is a corrosion and oxidation resistant nickel alloy that is used both for its high strength and outstanding aqueous corrosion resistance. Its outstanding strength and toughness is due to the addition of niobium which acts with the molybdenum to stiffen the alloy’s matrix. Alloy 625 has excellent fatigue strength and stress-corrosion cracking resistance to chloride ions. This nickel alloy has excellent weldability and is frequently used to weld AL-6XN. This alloy resists a wide range of severely corrosive environments and is especially resistant to pitting and crevice corrosion. Some typical applications Inconel 625 is used in are chemical processing， aerospace and marine engineering， pollution-control equipment， and nuclear reactors.
Nickel alloy steel Butt-weld caps， also known as Pipe Caps， suggest their function through their name: they act as a seal to the end of a pipe. Their primary function is to waterproof piping networks in addition to resisting chemicals， moisture and weather. Our end caps have pressure releasing abilities and flexible. We offer threaded ANSI B16.9 Pipe Caps for quick assembly that also avoid the pipe from getting cracked or damaged. Our End caps are available in high temperature resisting materials， in a variety of colours， finishes and in a wide array of sizes.
