Types of Buttweld Fittings:

At Astromet Steel and Engineering, we offer a number of fittings to your unique needs, such as;

Elbows

Elbows are used to change the route of go with the flow in a piping device. They come in 3 predominant angles: 45 degree, 90 degree, and 180 degree. 

  • 45-Degree Elbow: This elbow modifications the direction of drift through 45 ranges. It is frequently used in systems where space is confined or a mild exchange in direction is required.
  • 90 degree Elbow: The maximum common elbow, it changes the flow direction by way of 90 tiers, commonly used in plumbing, heating, and cooling systems.
  • 180-Degree Elbow: This elbow permits for a complete U-turn inside the piping device, useful in applications requiring a decent flip.

Buttweld Tees

Tees are used to mix or break up fluid flow in a piping gadget. They have 3 openings: one inlet and  retailers, or vice versa.

Buttweld Caps

Caps are used to seal the ends of pipes, stopping glides from exiting the pipe machine. They are crucial for shutting off unused or future connections.

Buttweld Reducers

Reducers are used to attach pipes of various diameters, ensuring an easy transition between varying pipe sizes.

  • Concentric Reducer: This reducer has a conical form and aligns the centerlines of both pipes, typically utilized in vertical piping structures.
  • Eccentric Reducer: This reducer has an off-center shape, stopping air pockets in horizontal piping structures.

Buttweld Stub Ends

Stub Ends are used along with lap joint flanges, taking into account easy assembly and disassembly of piping systems for inspection and preservation. They are available at diverse lengths and diameters, making them flexible for exclusive piping configurations. 

Buttweld Nipples

Nipples are quick lengths of pipe with male threads on both ends, used for connecting two other fittings or pipes.

Buttweld Crosses

Crosses have four openings and are used to break up or integrate glides in four directions. This nipple has a hexagonal middle, taking into consideration clean tightening with a wrench. It is usually used for connecting pipes in tight spaces where a firm grip is needed.
