What is Buttweld Fittings?

A Buttweld fitting is a part which is joined to a Buttweld. An American standard Buttweld thread is a type of screw or thread, commonly used on Buttweld fittings to assure a tight seal. A Buttweld fitting is a part which is joined to a Buttweld. These are used to combine, divert or reduce the flow of the water supply, and they come in a variety of sizes to fit the Buttweld they will connect.
Buttweld fittings dimensions are important and there are sizing standards to follow. While most have openings of the same size on each end, some fittings are designed with different-sized openings and serve as the transition from one size Buttweld to another. Buttweld Fittings are Piping component that helps in Changes the direction of the flow such as elbows, tees. Changes the size of the Buttweld such as reducers, reducing tees. Connect different components such as couplings and stop the flows such as Caps.

A pipe fitting is defined as a part used in a piping system, for changing direction, branching or for change of pipe diameter, and which is mechanically joined to the system.
There are many different types of fittings and they are the same in all sizes and schedules as the pipe.
Fittings are divided into three groups:-

  • 1. Buttweld (BW) fittings whose dimensions, dimensional tolerances are defined in the ASME B16.9 standards. Light-weight corrosion resistant fittings are made to MSS SP43. Butt weld fittings would also be referred to as welded pipe fittings
  • 2. Socket Weld (SW) fittings Class 3000, 6000, 9000 are defined in the ASME B16.11 standards.
  • 3. Threaded (THD) fittings Class 2000, 3000, 6000 are defined in the ASME B16.11 standards.
  • What is The Purpose Of Buttweld Fittings?

    Buttweld fittings manufacturer in India, also known as Buttweld connectors, attach one Buttweld to another in order to lengthen the run or change the flow direction in a plumbing system. These are used to combine, divert or reduce the flow of the water supply, and they come in a variety of sizes to fit the Buttweld they will connect.
    The basic purpose of using Buttweld fittings in Buttweld systems is to connect the bores of two or more Buttwelds or tubes. Buttweld fittings are used in piping systems normally :-

  • to connect straight Buttweld or tubing sections,
  • to adapt to different sizes or shapes,
  • to branch or re-direct the piping system,
  • if necessary to provide a jointing method if two dissimilar piping materials are used in the one system, and
  • for other purposes, such as regulating, measuring or changing the direction of the fluid flow or to connect up threaded Buttweld and equipment.

  • They are also used to close or seal a Buttweld.

    How Are Buttweld Fittings Classified?

    Buttweld fittings are generally classified as "welded" or "pressure" fittings. Welded fittings are welded on to the piping system where as pressure fitting uses National Buttweld Thread (NPT) to connect to the Buttweld. Pressure fittings are classified as 3000#, 6000# or 9000# (most common).

    What Are Materials Used For Buttweld Fittings?

    Fittings for Buttweld and tubing are most often made from the same base material as the Buttweld or tubing being connected, e.g., stainless steel, steel, copper, or plastic. However, any material that is allowed by code may be used but must be compatible with the other materials in the system, the fluids being transported, and the temperatures and pressures inside and outside of the system.
    The material with which a Buttweld is manufactured often forms the basis for choosing Buttweld fittings. Buttweld fittings are made of the following materials.

  • Carbon steel
  • Low-temperature carbon steel
  • Stainless steel
  • Malleable iron/ductile iron
  • Non-ferrous metals
  • Non-metallic materials
  • Chrome-molybdenum steel
  • Alloy Steel
  • Mild Steel
  • -normally used for high-temperature service

    What Are The Types Of Buttweld Fittings?

    While there are thousands of specialized Buttweld fittings manufacturers Ahmedabad, some common types of Buttweld fittings which are used widely in piping systems are- (i) elbow, (ii) tee, (iii) cross, (iv) reducer, (v) cap or plug, (vi) union, (vii) coupling, (viii) nipple, etc.

    Buttweld Fitting Specification & Standards

    Welded pipe fittings are made as per ASME spec B16.9. ASME B16.9 covers factory made wrought steel butwelding fittings in sizes 1/2" to 48". This standard however does not cover low pressure corrosion resistant buttwelding fittings. See MSS SP-43, Wrought Stainless Steel Butt-Welding Fittings.

    Benefits Of Buttweld Fittings?

  • Welded connection offers a more robust connection.
  • Continuous metal structure adds to the strength of the piping system.
  • Buttweld fittings with matching pipe schedules, offers seamless flow inside the pipe. A full penetration weld and properly fitted LR 90 Elbow, Reducer, Concentric reducer etc. offers gradual transition via welded pipe fitting.
  • Option of various turn radius using Short Radius (SR), Long Radius (LR) or 3R Elbows.
  • Cost effectivStainless Steel Welded Fittings are also available in SCH 10, allowing a more thinner wall option.
  • Stainless Steel Butt Weld Fittings are more common in SCH 10 and SCH 40 configuration.

  • All butt weld fittings have beveled ends as per ASME B16.25 standard. This helps create full penetration weld without any extra preparation needed for the butt weld fitting.
