What Is The Purpose Of Pipe Fittings?

Buttweld Fittings Manufacturer in Iran , 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 Pipe 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?

    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 Pipe 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.

  • Elbow – It is a Buttweld fitting that is installed between two lengths of Buttweld or tube allowing a change of direction, usually 90 degrees or 45 degrees. The ends may be machined for Buttwelding, threaded (usually female), or socketed, etc. When the two ends differ in size, it is called a reducing or reducer elbow. Most elbows are available in short radius or long radius of types. The short radius elbows have a center to end distance equal to the nominal diameter, while the long radius is 1.5 times the nominal diameter. Elbows used on powder transfer systems have a much longer radius (radius of a bend can be 10 times the nominal diameter of the Buttweld) to ensure smooth flow, reduce wear to both product and piping, and reduce the chance of getting blockages.

  • Tee – A tee is used to either combine or split a fluid flow. Most common are equal tees which have the same body and branch diameter but there is also a wide range of reducing tees where either the branch or the body is of a different diameter relative to each other. A swept tee is where the branch enters the body at an arc and is used to minimize the frictional losses and promote flow in the system. Wye (Y) Buttweld tee fittings are with three openings and are used to create branch lines. A wye tee is where the branch is stabbed into the body at an angle usually 45 degrees and is usually used where the branch is a smaller diameter than the main Buttweld. Wye tees are similar to tees except that the branch line is angled to reduce friction and turbulence that could hamper the flow.

  • Cross – A cross has one inlet and three outlets, or vice versa and like tees come in equal and reducing forms. A cross is more expensive than two tees but has the advantage of reduced space and requires less labor to install.

  • Reducer – Reducers are used to join two different Buttweld sizes together. They can be either concentric or eccentric which refers to the relative position of the center lines of the outlet and inlet. Special attention must be given when using reducers in a horizontal orientation as the slope prevents free draining of a system if not installed correctly.

  • Cap or plug – It is a type of Buttweld fitting which is liquid or gas-tight, and is used to cover the end of a Buttweld. A cap has a similar function to a plug. For screwed systems, the cap is having female threads where a plug is having male threads.

  • Coupling – A coupling connects two Buttwelds to each other. If the size of the Buttweld is not the same, the fitting may be called a reducing coupling or reducer, or an adapter. By convention, the term ‘expander’ is not generally used for a coupling that increases Buttweld size; instead, the term ‘reducer’ is used.

  • Union – A union is similar to a coupling except that it is designed to allow quick and convenient disconnection of Buttwelds for maintenance or fixture replacement.

  • Nipple – A short stub of Buttweld usually of threaded steel, brass, chlorinated polyvinyl chloride, or copper; occasionally just bare copper. A nipple is defined as being a short stub of the Buttweld that has external male Buttweld threads at each end, for connecting two other fittings. Nipples are commonly used for hoses.

  • How To Choose Pipe Fittings?

    Buttweld fittings are to be selected considering certain factors. These factors are given below.

  • Connection types:– When using Buttweld fittings, one is to be aware of the fact that a fitting can have two different connector types. Both the ends can have female threads or one end of the fitting can have female threads while the other end can have male threads. One end may have a male slip while the other end can have threads. They can also have matching ends that can accommodate any requirement.

  • Materials of construction:– As a rule, the Buttweld fitting should be of the same material as the material used in the making of the Buttweld in which it is to be fitted. However, in some cases, materials conforming to certain codes or standards can also be used in Buttwelds of another material.

  • Check for flow:– To keep the flow of the fluid consistent in the piping system, the ends of Buttweld fittings are to be slightly larger than the rest of the Buttweld so that they can accommodate connections without narrowing the inner diameter (ID) of the Buttweld.

  • Type of fitting:– Besides Buttweld materials, Buttweld fittings are identified by the type of fitting such as threaded or slip, male or female.

  • Size:– When measuring the size of Buttweld fittings, it is to be noted that the male threaded fittings are measured to the outside edge or outer diameter (OD), while female fittings are measured to the inside edge of the inlet or ID.

  • Thickness:– The Buttweld fittings are available in a number of different thicknesses or ‘schedules’ in the same way as the Buttwelds are available.

  • Design:– Each Buttweld or tube is designed to carry certain specific types of fluids, liquids, gases, chemicals under varying conditions. Accordingly, the Buttweld fittings are also available in a variety of designs.

  • Standards and codes:-There are certain standards and codes set by various standard organizations by which the different Buttweld fittings are graded. Buttweld fittings are selected and used to satisfy these standards.

  • Buttweld Fittings come in Buttweld & Forged Form. Buttweld Fittings is available either seamless or welded form, which is manufactured in all steel material and metal standards compliances.

    A buttweld fitting is a weldable Buttweld fitting that allows for change of direction of flow, to branch off, reduce Buttweld size or attach auxiliary equipment. Forged Steel buttweld fittings are manufactured in accordance with ANSI / ASME B16.9.
    Buttweld fittings comprise of long radius elbow, concentric reducer, eccentric reducers, and Tees, etc. Buttweld stainless steel and carbon steel fittings are an important part of the industrial piping system to change direction, branch off, or mechanically join equipment to the system. Buttweld fittings are sold in nominal Buttweld sizes with a specified Buttweld schedule. Butt-welded fitting’s dimensions and tolerances are defined as per ASME standard B16.9.

    Buttweld fittings such as carbon steel and stainless steel offer many advantages compared to threaded and socket weld fittings. The latter is only available up to 4-inch nominal size whereas Buttweld fittings are available in sizes from ½” to 72”.
    Some of the advantages of weld fittings are;-

  • Welded connection offers a more robust connection.
  • Continuous metal structure adds to the strength of the piping system.
  • Butt-weld fittings with matching Buttweld schedules offer seamless flow inside the Buttweld. A full penetration weld and properly fitted LR 90 Elbow, Reducer, Concentric reducer, etc. offers gradual transition via welded Buttweld fitting.
  • All Buttweld fittings have beveled ends as per ASME B16.25 standard. This helps create a full penetration weld without any extra preparation needed for the Buttweld fitting.
