Inconel 600 is a nickel-chromium alloy used for applications that require corrosion and high temperature resistance. This nickel alloy was designed for service temperatures from cryogenic to elevated temperatures in the range of 2000° F. It is non-magnetic, has excellent mechanical properties, and presents the desirable combination of high strength and good weldability under a wide range of temperatures. The high nickel content in Inconel 600 enables it to retain considerable resistance under reducing conditions, makes it resistant to corrosion by a number of organic and inorganic compounds, gives it excellent resistance to chloride-ion stress-corrosion cracking and also provides excellent resistance to alkaline solutions. Typical applications of this nickel alloy include the chemical, pulp and paper, aerospace, nuclear engineering and heat treating industries.
A Inconel 600 nipple manufactured at INSTINOX is a fitting, consisting of a short piece of pipe, usually provided with a male pipe thread at each end, for connecting two other fittings. The length of the nipple is usually specified by the overall length with threads. It may have a hexagonal section in the center for wrench to grasp (sometimes referred to as a “hex nipple”), or it may simply be made from a short piece of pipe (sometimes referred to as a “barrel nipple” or “pipe nipple”). The length of the nipple is usually specified by the overall length with threads. It may have a hex section in the center for wrench to grasp. A “close nipple” has no unthreaded area; when screwed tightly between two female fittings, very little of the nipple remains exposed. A close nipple can only be unscrewed by gripping one threaded end with a pipe wrench which will damage the threads[citation needed] and necessitate replacing the nipple, or by using a specialty tool known as a nipple wrench (or known as an internal pipe wrench) which grips the inside of the pipe, leaving the threads undamaged. When the ends are of two different sizes it is called a reducer or unequal nipple. A barrel nipple or a pipe nipple is one which is usually made from pipe and is threaded only at both ends.
A Inconel 600 pipe nipple is a protective sleeve that includes a sheath that is closed at a forward end and connects to a collar at an open rear end. On the other hand a Pipe reducer joins two pipes of different diameter. That is both pipe nipples and pipe reducers are not same. A pipe nipple is a manufactured piece of pipe that is threaded on both ends. A pipe reducer changes the size of pipe from one section to another. A reducer coupling has female threads on both ends and a reducer bushing has male threads on one end and female threads on the other.
The working pressure of pipe nipples will vary with the size and construction of the pipe, the type and number of clamps used, clamp placement, proper installation of clamps, temperature and product being conveyed. Pipe nipples are available in the widest variety of wall thicknesses and materials in the industry.

INSTINOX has one of the largest inventories of pipe nipples. Special end finishes and non-stock finishes are available. INSTINOX manufacturers pipe nipples, pipe, and pipe fittings in the wide array of wall thicknesses and materials for many industries. Carbon welded and seamless , brass, Inconel 600, aluminum, and copper.

We’ll supply you with special lengths, special threading, We appreciate the opportunity to serve you with the following types of pipe nipples:

Barrel nipple: This is a type of a short tubular with a taper thread outside at each end and which is un-threaded in the middle.

Weld nipple: Weld nipple is used as another method of connecting tube fittings. These kind of nipples are suitable for use under extreme conditions of vibration, pressure surges and changes of temperature.

Swage nipple: The basic purpose of a swage nipple is to bringing the flow of fluids from one pipe size to another. These are available with plain, beveled or threaded ends.
Hexagon nipple: Hexagon nipples are available in a variety of threads, materials and lengths.
