Butt Weld Fittings

Manufacturer

Butt Weld Fittings are useful to connect pipes from its ends which change the direction or diameter of the pipe. An ordinary butt weld fitting has one or more welds as per its dimension, manufacturing process and shape. Butt weld fittings is a method to link parts without additional tools which don’t overlap and are parallel to each other. This method helps in the continuous running of a machine. Beveling of ends of butt weld fittings leads to exceeding in wall thickness by 4mm in austenitic stainless steel and 5 mm in ferritic stainless steel. These bevels help to make “Butt-Weld”.
Generally, Butt Welding Fittings making takes place by heating two weld ends using a weld plate and joining it again in a specific pressure. Later, the outputs are ground down to a give a smooth finishing. To make a seamless butt weld fittings, you need to heat a section of seamless pipe material and add pressure to convert the pipe into an elbow.

Butt Weld Fittings

The Butt weld is a product of using an arc or MIG welder. Also, brazing helps in making this. When butt weld is complete using the arc welding, the weld is to be hit with a hammer so that the slag releases before applying further welds. The weld is inexhaustible when using MIG Welder which is coated with copper wire.Fittingcart has a huge stock of Butt Weld Fittings. We also include seamless butt weld fittings ranging from ½ inch to 12 inches and welded butt weld fittings from ½ to 24 inches. Also, we have a schedule range from 5S to 169 schedules.

Fittingcart is famous for the Butt Weld Fittings that it manufactures. In fact, we provide a varied range of Butt Weld Fittings which guarantee you a high level of strengths. Along with that, our Butt Weld Fittings can fit into any dimension as they are available in different shapes and sizes. Moreover, they are most durable and are at pocket-friendly prices. Other types of Butt Weld Fittings that Fittingcart produces include seamless butt weld fittings, industrial butt weld fittings, stainless steel butt weld fittings, carbon steel butt weld fittings, alloy steel and duplex steel butt weld fittings.On the other hand, we are also well-known for Tee butt weld fittings that we produce as Equal Tee and Unequal Tee. Stainless steel, alloy steel, and carbon steel are used to manufacture Tees to connect different diameters of pipes. Great tensile strength, the accuracy of dimensions, the resistance to corrosion, durability and finishing touch, Fittingcart’s Butt Weld Fittings are the most demanded in the market.

Types of Butt Weld Fittings

  • Long Radius Elbows 90º
  • Long Radius Elbows 45º
  • Short Radius Elbows 90º
  • End caps
  • Concentric Reducers
  • Eccentric Reducers
  • Short Length Stud Ends
  • Equal Tees
  • Reducing Tees

Dimensions and Fitting Sizes

The diameter and wall thickness of pipe fittings are as per the North American Standard and is Nominal Pipe Size (NPS). The international standard Diameter Nominal (DN). All the fittings begin from ½ inch to 12-inch “Nominal Pipe Size”, wherein outer diameters are larger than marked size and lead to shortening of inside diameters when schedules grow.

Advantages of Butt Welding over Flanges

To connect pipes using butt weld fittings, you need to weld them while on the other side, to connect pipes using flanges you need to bolt them together. Butt Weld Fittings need 10 to 75 percent less material as per its size whereas flanges require less. Butt weld fittings give smooth flow without sharp corners making no frictional resistance, no pressure loss and less turbulence.

Applications of Butt Weld Fittings
  • Widely used in chemical industries, shipbuilding sectors, construction industries, oil and gas industries, power plants, geothermal energy, etc.
  • Also used in food and beverage productions from normal equipment to elaborating deserts.
  • Useful in desalination of plants into transforming seawater into drinking for drought prone areas.
  • For the production of medicines, vaccines, pharmaceutical and biotech products.
  • Additionally, useful in the production of semiconductors like microchips, pulp-paper production, construction materials, plastics, roofing materials, etc.

Another North American standard called Schedule (sch) is the wall thickness measuring unit for a pipe fitting. To resist huge pressure, industries prefer buying fittings with high schedules which give them thicker walls.

Difference between a 3R and a 3D elbow

3R and 3D actually have no difference within them. Each of them has a 3x time’s centerline than the nominal diameter size. Also, they have smooth curves as compared to SR and LR. The diameter and number preceding it help you calculate the centerline radius. But yes, there is a major difference in the concentric reducers and the eccentric reducers. First and foremost, the concentric reducer is symmetrical wherein both ends are bend in the center. Whereas the eccentric reducer is not at all symmetrical, which means the ends don’t meet at the center. Also, you must know that lateral pipe fittings are helpful to divide one line into two where the second line meets at 45-degree angle.

Tips on Protecting Butt Weld Fittings
  • Make your outputs go through the Charpy test which rates the toughness of product therefore giving you the accurate energy that was suck during its fracture.
  • Avoid exposing them to corrosive fluids or materials.
  • Try metallurgical test which will study the physical structure and components of the output fittings.
  • Do not stretch your fittings too much as it may lead to appearing of deformation.
  • Ignore going for low or cheap cost tests as the special liquid used in them may lead to cracks and pores in the output fittings.
  • Use the exact and right amount of ferrite content to get excellent yield strength, toughness, and resistivity.
  • The hydrostatic test should be performed to check if there are any leaks in the product.
  • Use a magnetic to check if there is any surface discontinuity or weakness.
