Coupling Fittings-Butt Weld Pipe Fittings

Coupling Fittings

Pipe nipple is a length of straight pipe with male threads on both ends. It is one of the most popular category of pipe fittings.

It is a connector or a coupling threaded on both ends. Pipe nipples are used to allow plumbing to be connected to a water heater or other plumbing. They are used to fit straight end hose or pipe. A combination of pipe nipples are recommended for low-pressure discharge and suction service for various compatible liquids and not for compressible products like air, nitrogen or steam.

The length of the pipe 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”).

Coupling(Full & Half) Fittings

Full Coupling fittings

Half Coupling fittings

Reducer Coupling

Coupling fittings are used for fluid conduits in which each end portion of two tubes to be connected is provided with a swaged-on adapter carrying the necessary means to connect or disconnect the tubes without disturbing the swaged-on adapter. Our range of coupling fittings are available in aluminium, steel and bronze.

Pressure: 2000LBS, 3000LBS, 6000LBS, 9000LBS
Size: from 1/4" to 4"
Material: ASTM A105, F304, F316, F304L, F316L, A182 F11/F22/F91

Connection ends: butt welded, threaded
Standard: ANSI B16.9/B16.28 and MSS SP-43/SP-75

Connection ends: butt welded, threaded
Thread types: NU, EU, STC, LTC and BTC

Surface treatment:Shot blasted, rust-proof black oil
A pipe coupling is also often used to facilitate changes of pipe routing, crossing of obstacles, and penetration of walls. These couplings are typically elbow or U shaped but may include several variants featuring different angles of deflection. Step-down or reduction pipe couplings featuring different end diameters are used to join pipes of dissimilar sizes. Adaptor fitting may also be used to join pipes of different materials and feature separate end fittings suitable for both materials. Where more than two pipes are to be joined Y, T, or cross shaped couplings are common methods of achieving the joints.

ANSI/ASME B16.25 standard specification

ANSI/ASME B16.25 is the standard covers the preparation of butt welding ends of piping components to be joined into a piping system by welding. The standard includes the butt welding ends information of General scope, Welding Bevel designs, Preparation of inside diameter of welding ends and the tolerances involved. ANSI/ASME B16.25, Buttwelding Ends Following are the dimensions of the butt welding pipe ends according to ANSI B16.25. It includes requirements forwelding bevels, for external and internal shaping of heavy-wall components, and for preparation of internal ends (including dimensions and tolerances). Coverage includes preparation for joints with the following: (a) no backing rings (b) split or noncontinuous backing rings (c) solid or continuous backing rings (d) consumable insert rings (e) gas tungsten arc welding (GTAW) of the root pass Details of preparation for any backing ring must be specified when ordering the component. ANSI/ASME B16....

How to Calculate a Pipe Bend?

Pipe fittings are necessary to join together pipes, or to change the direction of an existing pipe. Pipes and pipe fittings are made of a variety of materials, depending on the fluid or gas being transported. Most pipe fittings tend to be either threaded or able to slip over the pipes they connect. Whether you are using steel pipes of PVC pipes, a chemical solvent is required to create a seal between the pipe and the fittings. Calculate a Pipe Bend Measure the required length of the pipe to be installed, keeping in mind the extra length required where the pipe will be inserted into the fitting. Mark this length on the pipe. How to Calculate a Pipe Bend Whether you are bending pipe for running electrical conduit or a metal project, calculating the bend for the start and end point can be an important factor. While there are different types of pipe benders on the market, they all share a common identification for the operation. Identified on all pipe benders is the size of pipe the unit w...

ANSI Flange Standards

The American National Standard Institute, ANSI, has been overseeing guidelines and standards for products manufactured through several sectors. WHAT IS ANSI? ANSI-approved flanges are used for the industrial market which handles gas, air and steam process systems. Originally formed in 1918, the American National Standards Institute is headquartered in Washington, DC, and is widely recognized as the American organization responsible for overseeing the national standards and conformity assessment system for products, services, processes, systems, and personnel. ANSI works domestically with American government agencies and organizations, as well as with international entities, to make ANSI standards useful around the world. Prior to the creation of ANSI, standards for engineering and equipment such as flanges were developed by the American Institute of Electrical Engineers (AIEE or IEEE), the American Society of Mechanical Engineers (ASME), the American Institute of Mi...
